		<description><![CDATA[Wireless is just the latest of Conexant's cuts. The company just got done culling 500 employees, and it's stopped working on new network processors, packet-processing chips, and chips for the HomePlug Powerline Alliance 's home-networking standard.]]></description>
			<content:encoded><![CDATA[<p>Still trying to slim down, chip firm Conexant Systems Inc. (Nasdaq: CNXT) is halting new development of wireless LAN chips and laying off 140.</p>
<p>The news came yesterday as Conexant reported its fourth-quarter earnings, and the change took effect immediately. By late afternoon yesterday, the &#8220;wireless products&#8221; link had been removed from Conexant&#8217;s home page. (See Conexant Reports Q4.)</p>
<p>Conexant will continue building wireless LAN technology into products such as DSL gateway chipsets, and the company says it will continue supporting its current wireless customers. But development of any new wireless products is out.</p>
<p>Wireless is just the latest of Conexant&#8217;s cuts. The company just got done culling 500 employees, and it&#8217;s stopped working on new network processors, packet-processing chips, and chips for the HomePlug Powerline Alliance &#8217;s home-networking standard.</p>
<p>That still leaves Conexant with a broad portfolio including chips for DSL, set-top boxes, video, VOIP, and passive optical networking (PON). </p>
<p>Conexant had about 3,000 employees five weeks ago, before all these cuts, so it&#8217;s dropped headcount by about 20 percent, to around 2,360. </p>
<p>Conexant has been in flux as officials try to steer the company back to the breakeven point. New CEO Daniel Artusi took the helm in June to lead the restructuring, and the company got a new CFO in September. (See Artusi to Helm Conexant and Conexent Names CFO.)</p>
<p>The de-emphasized products won&#8217;t necessarily get sold off. &#8220;We are in discussion with several parties to sell some selected assets in some of these businesses, but the plan right now is to wind down these businesses,&#8221; Artusi said on a conference call with analysts yesterday.</p>
<p>For its fourth quarter, which ended Sept. 28, Conexant reported revenues of $183.9 million and losses of $234.8 million, or 48 cents per share, compared with third-quarter revenues of $179.6 million and losses of $35.2 million, or 7 cents per share. </p>
<p>For its fourth quarter a year ago, Conexant reported revenues of $245.9 million and losses of $21.1 million, or 4 cents per share. </p>
<p>Conexant shares were down 2 cents (1.6%) at $1.21 in after-hours trading.</p>

Only the court clerk could make that change, Frenkel wrote, and he cites an email that "suggested" the attorneys convinced the clerk by phone to do it.]]></description>
			<content:encoded><![CDATA[<p>Now that the world knows a Cisco Systems Inc. (Nasdaq: CSCO) employee is behind the Patent Troll Tracker blog, it&#8217;s no surprise to see the company&#8217;s name show up in defamation lawsuits.</p>
<p>Two Texas attorneys are suing blogger Richard Frenkel over some postings made in October. And they&#8217;ve named Cisco as a defendant as well.</p>
<p>Eric Albritton filed his suit on March 3 in the District Court of Gregg County, Texas, followed by John Ward Jr., who filed March 13. Both are seeking unspecified damages </p>
<p>Patent Troll Tracker is a blog that investigates patent lawsuits &#8212; specifically, the ones Frenkel thinks are frivolous.</p>
<p>The term &#8220;patent troll&#8221; gets tossed around rather loosely, but usually, it refers to someone who holds a patent and just waits around for a chance to sue someone. Anti-troll crusaders get particularly irked in cases where the patent holder makes no effort to build the product patented. </p>
<p>The practice is legal and can pay off big. In 2006, Research In Motion Ltd. (RIM) (Nasdaq: RIMM; Toronto: RIM) paid $612.5 million to NTP Software Inc. , which held patents crucial to the BlackBerry device and service. NTP has gone on to sue Palm Inc. , AT&#038;T Inc. (NYSE: T), and Verizon Communications Inc. (NYSE: VZ). (See RIM, NTP Come to Terms, NTP Takes Another Shot, and NTP Rides Again.)</p>
<p>The suits against Frenkel don&#8217;t strike at any big patent questions. Instead, they&#8217;re about some alleged legal maneuvering which, if it happened, could get Albritton and Ward in hot water.</p>
<p>Albritton and Ward were among the attorneys representing a company called ESN, which filed a patent suit against Cisco and Linksys on Oct. 15, 2007. But the patent in question, No. 7,283,519, didn&#8217;t get issued until Oct. 16. </p>
<p>Frenkel pointed this out in a blog entry of Oct. 17, according to a copy attached to Albritton&#8217;s complaint. Frenkel went on to say ESN was trying to change the date on its complaint to Oct. 16.</p>
<p>And in a posting the following day, he said the date did indeed get changed on the docket for the Eastern District Court of Texas. Only the court clerk could make that change, Frenkel wrote, and he cites an email that &#8220;suggested&#8221; the attorneys convinced the clerk by phone to do it.</p>
<p>&#8220;You can&#8217;t change history, and it&#8217;s outrageous that the Eastern District of Texas is apparently, wittingly or unwittingly, conspiring with a non-practicing entity to try to manufacture subject matter jurisdiction,&#8221; Frenkel wrote. &#8220;This is yet another example of the abusive nature of litigating patent cases in the Banana Republic of East Texas.&#8221;</p>
<p>So, how does Cisco get roped into this, if Frenkel was acting on his own? The key appears to be the way in which Fenkel outed himself.</p>
<p>Until last month, the author of Patent Troll Tracker was a mystery. His writings were infuriating some patent attorneys, though. Raymond Niro, a partner in Chicago-based Niro Scavone Haller &#038; Niro, offered a reward for anyone who could unmask the blogger; the amount started at $5,000 and eventually climbed to $15,000. </p>
<p>Last month, for reasons that still aren&#8217;t clear, Frenkel came clean about his name and occupation. He claimed Cisco&#8217;s higher-ups had no knowledge of what he was doing &#8212; but that his manager did. </p>
<p>That last part might be what&#8217;s allowing some legalese to get pointed Cisco&#8217;s way.</p>
<p>&#8220;Defendant Frenkel has publicly admitted that he engaged in this activity with the full knowledge and consent of his employer,&#8221; Ward&#8217;s complaint reads &#8212; meaning &#8220;Cisco is vicariously and directly liable for the intentional torts of Defendant Frenkel.&#8221;</p>
<p>From there, Ward goes on to claim Cisco (and Frenkel) were intentionally attacking him in hopes of damaging his business. </p>
<p>Albritton&#8217;s complaint follows similar lines. Further, Albritton notes that Frenkel was a Cisco manager and claims Frenkel was involved with the ESN case. </p>
<p>Both complainants also accuse Frenkel of gaming search engines to make his blog appear when their names are used as search keys. Light Reading&#8217;s quick Google checks of &#8220;Albritton&#8221; and &#8220;Eric Albritton&#8221; didn&#8217;t turn up Patent Troll Tracker on the first page, but that might be because Patent Troll Tracker has shut itself in. It&#8217;s an invitation-only blog now.</p>
<p>Cisco declined to comment but issued a statement that reads, in part: &#8220;We would like to underscore that the comments made in the employee&#8217;s personal blog represented his own opinions and several of his comments are not consistent with Cisco&#8217;s views.&#8221;</p>

			<content:encoded><![CDATA[<p>Reliance Communications Ltd. (RCom) , which runs India’s second largest mobile network, has made its first international mobile acquisition, in Africa. (See Reliance Buys Into Uganda.) </p>
<p>Reliance has acquired Anupam Global Soft (U) Ltd., a service provider license holder in Uganda, for an undisclosed sum and plans to invest $500 million over the next five years building an IP-based network there. </p>
<p>Anupam Global expects to launch GSM services by the end of the year. Reliance says it will also offer fixed-line, Internet, and long-distance services, and is looking to roll out WiMax and wireless LAN. </p>
<p>The move marks the beginning of Reliance&#8217;s expansion into emerging Asian and African mobile markets. Africa provides fertile ground for acquisitive telcos as the fixed-line infrastructure is underdeveloped, telephone penetration remains low, and governments are increasingly liberalizing their markets, all creating huge potential for further growth. </p>
<p>Uganda had 4.2 million mobile subscribers and 162,263 fixed lines at the end of September 2007, according to the Uganda Communications Commission (UCC), in a population of around 30 million. </p>
<p>Reliance will be competing with fixed-line incumbent Uganda Telecom and its mobile subsidiary UT Mobile; MTN Group Ltd. ; and Celtel International B.V. On top of that, HiTs Telecom is also in the process of setting up operations in Uganda. </p>
<p>Reliance&#8217;s FLAG subsidiary is already building a presence in Africa as part of its global NGN initiative. It&#8217;s laying a submarine cable system that will provide the underserved continent with connectivity to the rest of the world, helping bring down the cost of providing communications in the region.</p>

		<description><![CDATA[For example, a basic application, such as enabling customers to buy a product online and pick it up at the store, will touch many different IT systems operated by a retailer, from the Web-based ordering, to inventory management, pricing, control of delivery using third-party operators, and more, Bagal said. What the Verizon Retail Framework is offering is a way to orchestrate those interactions, using the existing IT systems for individual functions. ]]></description>
			<content:encoded><![CDATA[<p>Verizon Business has announced a new initiative designed to help retail customers modernize their IT infrastructures using an open standards approach. As part of this initiative, announced at the National Retail Federation show in New York City this week, Verizon also announced its support for the Association for Retail Technology Standards (ARTS) and unveiled its own open standards framework for retail services. </p>
<p>The first service to be offered via the Verizon Retail Framework will be a wireless security solution, in partnership with Motorola Inc. (NYSE: MOT). The managed wireless security solution is aimed at protecting the growing number of in-store wireless LANs being used both for internal purposes and for customer use, said Ravi Bagal, global managing director, retail and distribution, Verizon Business. </p>
<p>In general, retail use of IT technology suffers from what Bagal termed “point solution pollution” &#8212; the development over time of many individual solutions that don’t interoperate, some of which may also be outdated and inefficient.</p>
<p>”The Verizon Framework for Retail is intended to address the need for interoperability of these systems,” Bagal said. “Rather than having to rip out existing systems or repair them, retailers can use solutions hosted in the cloud to integrate new capabilities and use the functionality of existing systems.”</p>
<p>For example, a basic application, such as enabling customers to buy a product online and pick it up at the store, will touch many different IT systems operated by a retailer, from the Web-based ordering, to inventory management, pricing, control of delivery using third-party operators, and more, Bagal said. What the Verizon Retail Framework is offering is a way to orchestrate those interactions, using the existing IT systems for individual functions. </p>
<p>The use of open standards enables retailers to take a best-of-breed approach to buying IT from multiple vendors and move away from dependence on proprietary systems that don’t interoperate, according to Bagal.</p>
<p>Verizon Business and Motorola chose to partner on a managed wireless security service to address a growing problem that the increasing use of WiFi and other wireless LANs is creating, said David Thomas, director of product management and strategy for Motorola AirDefense, Motorola Enterprise Mobility Solutions. </p>
<p>Critical information, such as credit card numbers and social security numbers, is being put at risk by transmission over unsecured wireless networks, Thomas said, and retailers are coming under fire when such customer information is compromised. </p>
<p>Verizon will offer a range of solutions using Motorola AirDefense wireless security products, which were developed by AirDefense &#8212; acquired by Motorola in 2008 &#8212; to protect 802.11 wireless LANs against unauthorized access of any kind, Thomas said. </p>
<p>Verizon can monitor the service or fully manage it, depending on customer needs, Bagal noted. The new offering will bring retailers into compliance with Payment Card Industry (PCI) security standards. </p>
<p>The retail initiative is one of several industry-specific efforts by Verizon Business in recent years. To move away from more generic sales approaches, Verizon hires experts within a specific field, such as retail or healthcare, both to help design more specific IT and telecom solutions for that field and to enable its sales personnel to speak the language of the customer, Bagal said.</p>

			<content:encoded><![CDATA[<p>Singapore&#8217;s government is to partly fund the construction of a nationwide broadband network that, once built, could be used by any operator to deliver services to the country&#8217;s 4.5 million residents. (See Singapore Issues RFP.) </p>
<p>The Infocomm Development Authority of Singapore (IDA) has issued an expanded request for proposals (RFP) inviting any company or consortium to bid for the right to build a network that, by 2015, will provide &#8220;pervasive and competitively priced ultra high-speed broadband connectivity [1 Gbit/s or more] to business users at the workplace as well as to Singaporeans at home, schools and learning institutions and other premises.&#8221; </p>
<p>The IDA pre-qualified 12 bidders for the network deal and has been consulting them to establish the fine detail of the RFP that&#8217;s now available to all comers. Among those 12 are incumbent operator Singapore Telecommunications Ltd. (SingTel) (OTC: SGTJY); local cable operator StarHub Pte. Ltd. ; Siemens Communications, now part of Nokia Siemens Networks ; and Japan&#8217;s NTT West Corp. , all of which submitted single company bids, even though some have sourced technology partners. (See StarHub Goes Out-of-Band With Vyyo.) </p>
<p>The remaining pre-qualified bidders are all consortia, including teams in which Alcatel-Lucent (NYSE: ALU), Cisco Systems Inc. (Nasdaq: CSCO), Ericsson AB (Nasdaq: ERIC), BT Group plc (NYSE: BT; London: BTA), Tech Mahindra Ltd. , Chunghwa Telecom Co. Ltd. , T-Systems Inc. , Hong Kong Broadband Network Ltd. (HKBN) , and MobileOne Ltd. (M1) (Singapore: MONE) are involved. </p>
<p>To help attract more bidders, the country&#8217;s government will provide a grant of up to 750 million Singaporean dollars (US$520 million) to the &#8220;NetCo,&#8221; which will &#8220;design, build and operate&#8221; the &#8220;passive infrastructure.&#8221; </p>
<p>The government will then choose an &#8220;Operating Company&#8221; to deploy network infrastructure (routers, switches) and act as a wholesaler of broadband capacity, which will then be sold to multiple retail service providers. </p>
<p>That three-layered model &#8212; network, operations, services &#8212; is similar to Amsterdam&#8217;s municipal network rollout, notes Heavy Reading chief analyst Graham Finnie, who finds the project &#8220;really interesting.&#8221; (See Amsterdam Fires Up Muni Broadband.) </p>
<p>&#8220;Talk about this project has been around for a while, and the open access enthusiasts are very excited about it. That&#8217;s because the momentum behind the open network model has largely been in Northern Europe so far, in the Netherlands and Scandinavia, but this is a large project in a different part of the world &#8212; it validates the model,&#8221; says Finnie. </p>
<p>Finnie notes that Singapore, with its high population density, is ideal for a fiber-to-the-home rollout. He estimates that the total cost of building the network could be as high as US$2 billion. </p>
<p>Given the size of the project, and the attention it will likely attract, Finnie believes the vendor community, especially companies such as Cisco and PacketFront AB , which are already supplying infrastructure for European open network projects, will &#8220;go hell for leather to be involved with this.&#8221; (See Amsterdam Gets Active With FTTH and PacketFront Touts FTTH Success.) </p>
<p>The analyst expects all the major infrastructure vendors to be keen on the Singapore project, and expects AlcaLu to propose GPON as the access technology of choice. </p>
<p>Active Ethernet, where each customer is linked to a dedicated fiber connection, has been the technology approach of choice so far for such networks, says Finnie, but &#8220;Alcatel-Lucent is trying to promote GPON as an open access alternative.&#8221; (See Bright Prospects for GPON and CitéVision Uses AlcaLu GPON .) </p>
<p>The RFP closes on March 25, 2008, after which the IDA will evaluate the submissions. </p>
<p>Singapore&#8217;s residents won&#8217;t have to wait until 2015 to benefit from the new network, though, as the IDA expects services such as &#8220;high-definition video conferencing, telemedicine, grid computing-on-demand, security, and immersive learning applications&#8221; to be made available from 2010 onwards. </p>
<p>The new network build is part of Singapore&#8217;s Next Generation National Infocomm Infrastructure (NGNII), which includes a nationwide WiFi rollout of 6,000 hotspots that began in December 2006.</p>

		<description><![CDATA[For government prosecutors, it's an embarrassing end to a high-profile case. In 2007, Broadcom had to restate $2.2 billion in on-paper earnings after it was revealed that the company hadn't properly accounted for backdated stock options.]]></description>
			<content:encoded><![CDATA[<p>A federal judge has crippled the U.S. government&#8217;s options-backdating cases against former Broadcom Corp. (Nasdaq: BRCM) executives, and the federal drug case against former CEO Henry Nicholas III could fall apart next.</p>
<p>Yesterday, U.S. District Court Judge Cormac J. Carney acquitted former Broadcom CFO William Ruehle of fraud charges and dismissed criminal fraud charges against Nicholas. </p>
<p>He also dismissed a Securities and Exchange Commission (SEC) case against four Broadcom executives: Nicolas; Ruehle; former CTO Henry Samueli; and former general counsel David Dull. Civil charges were filed in that case in May 2008. (See Options Scandal Deepens at Broadcom.)</p>
<p>Carney ruled that prosecutors had improperly meddled with the executives&#8217; defense by intimidating potential witnesses &#8212; specifically, Samueli, Dull, and former Broadcom vice president of human resources Nancy Tullos. As a result, reports say, Carney didn&#8217;t think Nicholas and Ruehle could get fair trials.</p>
<p>Last week, Carney also tossed out Samueli&#8217;s guilty plea from June 2008. That plea came with a $12.2 million fine and five years of probation, but also with a promise that Samueli wouldn&#8217;t have to testify against Nicholas; the two men are longtime friends who founded Broadcom together. (See Broadcom: Guilty Plea.)</p>
<p>The Orange County Register describes a courtroom scene made for TV: Nicholas and Samueli, who hadn&#8217;t spoken in years due to the ongoing court cases, hugging in the aisle after Carney&#8217;s ruling. </p>
<p>The dismissals might affect the government&#8217;s case against Nicholas for drug distribution. Reports say Carney double-dared prosecutors (so to speak) to come up with reasons why that case shouldn&#8217;t be thrown out, considering Nicholas&#8217;s defense would rely on the same set of witnesses as the options case. </p>
<p>For government prosecutors, it&#8217;s an embarrassing end to a high-profile case. In 2007, Broadcom had to restate $2.2 billion in on-paper earnings after it was revealed that the company hadn&#8217;t properly accounted for backdated stock options. (See Broadcom&#8217;s $2.2B Confession.) </p>
<p>Options backdating isn&#8217;t illegal, but many, many companies weren&#8217;t properly accounting for the costs of those options. </p>
<p>Another high-profile options case that went to trial was that of Gregory Reyes, former Brocade Communications Systems Inc. (Nasdaq: BRCD) CEO. Reyes&#8217;s conviction got overturned in August. (See Brocade Ruling Gets Erased.) </p>
<p>Earlier this month, however, prosecutors confirmed that they&#8217;ll give it another go. </p>
<p>The court rulings gave Broadcom something extra to talk about at its annual analyst meeting, held yesterday in Santa Clara, Calif. </p>
<p>Broadcom used the occasion to announce a better forecast for fourth-quarter earnings. (See Broadcom Brightens Q4 Outlook.) </p>
<p>CFO Eric Brandt joked during his afternoon presentation that it would have been nice to have gotten the court decisions earlier; apparently, Broadcom&#8217;s operating expenses have been hard to predict due to legal fees.</p>
<p>Broadcom now says fourth-quarter revenues will be around $1.32 billion, as opposed to the $1.25 billion previously announced, and that gross margins on its product sales will be better than expected. Broadcom stock traded roughly flat after-hours.</p>

			<content:encoded><![CDATA[<p>wireless network, at least according to Motorola Inc. (NYSE: MOT). </p>
<p>Motorola didn&#8217;t invent this idea, but it&#8217;s one of the few saying the ability to go purely wireless is here now (although major rival Aruba Networks Inc. (Nasdaq: ARUN) has talked up the concept in the past). At recent media events held in Boston and San Francisco, Motorola executives stated their case, basing it on the rise of 802.11n and the advent of new reliability techniques. </p>
<p>Yes, it&#8217;s a marketing message. But it&#8217;s also Motorola&#8217;s chance to stand out against a crowd of second fiddles battling Cisco Systems Inc. (Nasdaq: CSCO), which leads in sales of wireless LAN gear. </p>
<p>&#8220;What Cisco is to wired, we think we could be for wireless,&#8221; says Sujai Hajela, Motorola&#8217;s vice president of enterprise wireless LAN. </p>
<p>Just to be clear: Motorola isn&#8217;t advocating that anyone replace their wired LANs (although they&#8217;ve had at least one customer do that). Gartner Inc. analyst Michael King notes that the idea is mostly being applied to newly built offices, or cases where a company&#8217;s networking gear of choice is being discontinued.</p>
<p>Motorola has another case in mind. Because network expansions will probably use 802.11n as an access medium, why not use 802.11n for hooking up aggregation switches and wiring closets, too?</p>
<p>&#8220;We&#8217;re not proposing that companies start ripping out wires. But as you implement 802.11n, you do not have to grow this pile of wires,&#8221; Hajela says.</p>
<p>By Motorola&#8217;s count, the result would save an enterprise a lot of money. The company gives an example of one greenfield network where wired Ethernet would incur recurring costs of $88 per user per year in maintenance and support, versus $12.51 for a wireless network. </p>
<p>Moreover, a company fully exploiting a wireless LAN mesh might be able to cut down on the number of switches it needs, since it theoretically wouldn&#8217;t have to wire up as many connections. </p>
<p>Motorola cites one customer that used 12 of Cisco&#8217;s Catalyst 6500 boxes as an distribution layer, the last layer feeding into the business&#8217;s small network core. By using wireless hookups for most of its network, including that distribution layer, the enterprise found it could do without six of those 6500s.</p>
<p>Helping boost the trend is the fact that telephones are going increasingly wireless or are being replaced with PC-based alternatives. It&#8217;s one part of the network that doesn&#8217;t need much prodding to go wireless. &#8220;We&#8217;re at a point in time where the market is already penetrated,&#8221; Gartner&#8217;s King says. </p>
<p>To complete the picture, an office could even use a wireless connection to hook its network to the outside world. Eventually, that could be WiMax; for now, 802.11n could be an option.</p>
<p>None of this could be pulled off, on any large scale, without 802.11n. The protocol&#8217;s higher bandwidth means the all-wireless network can be built with fewer access points than before &#8212; which lowers equipment costs and management difficulties. </p>
<p>That&#8217;s got other wireless vendors thinking along similar lines, although not as aggressively as Motorola. &#8220;You could say that some of them are ahead of the market,&#8221; King says. &#8220;They&#8217;ve got the story set up for the verticals but without experience in those markets.&#8221;</p>
<p>So, the bandwidth is there to make an all-wireless network possible. Motorola still has to counter the two issues that always come up with WiFi: reliability and security.</p>
<p>Motorola says it can get around a lot of reliability problems with its adaptive access point technology, announced in February. (See Motorola Gets Adaptive.) The technology lets an enterprise manage its 802.11 network, including branch offices, from a centralized point. It also supports a mesh topology, so traffic can be steered in another direction if one access point goes down. </p>
<p>And Motorola is outright dismissing the security question. The 802.11 network can be infused with just as much security as a wired network, Hajela says; moreover, wired networks are notorious for not having security activated. In summary, Motorola claims a WiFi operation wouldn&#8217;t be any less secure than the networks being used now. </p>
<p>Others in wireless question whether Motorola&#8217;s got all the answers, though. </p>
<p>&#8220;It&#8217;s difficult to see an office that is purely wireless. You can&#8217;t do wireless without wired,&#8221; says Chris Kozup, Cisco&#8217;s manager of mobility products. </p>
<p>One question is how much bandwidth the aggregation layer would take up. &#8220;There&#8217;s only so much spectrum in the 2.4 and 5 GHz bands,&#8221; Kozup says. &#8220;You quickly run into scalability limitations when you&#8217;re doing that.&#8221;</p>
<p>Kozup and others also point out that an all-wireless enterprise would probably have to rely on sending data across multiple hops between access points.</p>
<p>&#8220;Inter-AP hops are bad, degrading the performance often 50 percent or more,&#8221; says David Callisch, director of marketing for Ruckus Wireless Inc. </p>
<p>Ruckus gets around that problem with its directional-antenna gear, which it says is a a better alternative to just relying on the multiple-input, multiple-output nature of 802.11n. &#8220;Ultimately there’s no reason why an all WiFi enterprise shouldn’t exist,&#8221; Callisch says.</p>
<p>Kozup contends the all-wireless idea is better suited for a remote branch offices. Networks there are subject to frequent changes or even relocation, so having fewer wires to plug in seems attractive, he says.</p>

			<content:encoded><![CDATA[<p>Mobile World Congress &#8212; How will the rapid growth of the mobile Internet be funded? And who will reap the spoils from a wealth of new wireless data applications and services? Those questions have been vexing operators, vendors, and content providers here at the show, and it came bubbling to the surface in this morning&#8217;s keynote session.</p>
<p>On one side was Masayoshi Son, CEO of Japanese wireless and mobile operator Softbank , who advocated a combination of micropayments and ad-funded content to derive revenue from wireless. On the other was Marco Boerries, head of connected life at Yahoo Inc. (Nasdaq: YHOO), who, while stressing the firm&#8217;s carrier partnerships, argued that a consumer-driven, ad-funded, open-Internet-like model was the way. Somewhere in the middle was Research In Motion Ltd. (RIM) (Nasdaq: RIMM; Toronto: RIM) co-CEO Jim Basilie, who claimed that his company and others can help carriers to become &#8220;value-added platforms&#8221; in this colorful new world of mobile content.</p>
<p>Son&#8217;s contention is that the wireless Internet is fundamentally unlike the wired Internet because classic Google (Nasdaq: GOOG)-style online advertising will not work on the smaller screen, and content downloads will always be limited by the amount of radio spectrum available to operators.</p>
<p>Son even suggests that, as more users get online wirelessly, the current hegemony of the Internet could change. &#8220;The glory of Google may not last another 20 years,&#8221; he quipped. &#8220;With a small screen, if you have too many flashy ads, it is too noisy.</p>
<p>&#8220;For the PC, Internet advertising was 80 or 90 percent of the revenue,&#8221; Son continued. &#8220;For the mobile Internet it will be maybe 20 percent.&#8221;</p>
<p>High-value content, such as mobile video downloads, will be paid for by micropayments rather than funded by ads. This, suggested Son, will also help to ensure that willy-nilly &#8220;rich media&#8221; downloads don&#8217;t take an operator by surprise.</p>
<p>&#8220;The rich media cannot come onto the mobile network without any control,&#8221; Son said. &#8220;YouTube [downloads] are guaranteed to kill the network in the night-time.&#8221;</p>
<p>Yahoo&#8217;s Boerries, however, is favoring a far more open approach to drive up user numbers for the mobile Internet. &#8220;The ad market is all about scale,&#8221; Boerries expounded. &#8220;If we don&#8217;t get to millions of users and eventually billions of users using [social networking and other] services several times a day, then this model doesn&#8217;t scale.&#8221;</p>
<p>This necessarily requires open access to applications and services and an ad-driven model, Boerries claims, while acknowledging that micropayments may have a role to play. &#8220;We&#8217;re trying to re-invent mobile advertising,&#8221; he said, using uniquely mobile aspects like a user&#8217;s location to make the marketeering &#8220;constantly relevant&#8221; to a user.</p>
<p>Borries acknowledged carrier fears that opening up networks would make them little more than a dumb pipe but claimed that Yahoo and others will add to an operator&#8217;s revenue pot, not take away from it through revenue sharing deals. &#8220;They don&#8217;t share their data plan revenue with us &#8212; we&#8217;re creating new mobile ad-revenue.&#8221;</p>
<p>RIM co-head Basilie acted as something of a middle way between a carrier-driven mobile Internet and an ad-supported free and easy model. RIM and others, he suggested, can help carriers develop as a &#8220;value-added platform&#8221; and not be &#8220;disintermediated&#8221; on the new mobile frontier.</p>
<p>Basilie even had a helpful suggestion on how to ensure that mobile cellular networks aren&#8217;t &#8220;killed&#8221; by a massive increase in video downloads. &#8220;You can also use WiFi for side-loading,&#8221; he suggested. That is, if a user wants a video download immediately, then they make an additional micropayment for the privilege, or automatically wait until they are near a hotspot to pull down the clip, which is then cached in the phone&#8217;s memory, ready to be played.</p>
<p>&#8220;That&#8217;s a wonderful strategy,&#8221; Basilie claimed.</p>
<p>Side-loading, however, was shot down by the Softbank CEO. &#8220;In the U.S., the networks are so slow that you need to use WiFi,&#8221; Son stated to laughter from the crowd. &#8220;In Japan, our network is so fast people want to use it.&#8221;</p>

			<content:encoded><![CDATA[<p>Basic station where the small family flows &#8212; Can lengthen its convergent quotation for service, Englishmen porters are announced by today.   </p>
<p>But the operator warns that it is still too high to use the expenses of femtocells effectively.   (See 3 G &#038; WiMax Femtocells: Operator&#8217;s opinion.)   </p>
<p>&#8221; We are making the technology assessment of femtocells, like other each person, but the big problem is the expenses, &#8221;   Warren and Barclay, the executive of BT that the mobility peace conference is collected says, speaks at Informa Femotcell solution meeting in London.   </p>
<p>Barclay emphasizes operators have not decided yet whether to use femtocells effectively, but the family  Basic station can offer one method expand electric current range assemble operator melt / can collect while being flexible through definite it BT Mobile phone and service offered.   (see passway BT melt the difficult key moved.)   </p>
<p>But he point out running prices farther house centre house expense of passway of BT of femtocell, BT has already shipped and exceeded 2 million.   (whether see house centre No. ship, BT of Tomson, BT gets a passway.)   </p>
<p>&#8221; The expenses in the center of BT home are analogous to anything we are less than what has been spoken 5,000 of a femtocell, &#8221;   Barclay says.   &#8221; The expense model does not prove now I am the correct putting femtocell into centre of home.  &#8221;  (see Femto athlete hunt the passway.)  </p>
<p>BT checks how to connect broadband with to the key network moved the station of home base those Great Britain and the United Kingdom femtocells, Northern Ireland of any arrangement too Connect and is used in backhaul, can influence the traffic in the porter&#8217;s entry network.   Barclay, but say porters&#8221;  Do not worry influencing in the bandwidth of femtocells above our broadband.  &#8221; </p>
<p>BT people say porter experience with melt and inhabit passway notify BT house in the center broadband of decision of it at femtocells together.   </p>
<p>Melting does not succeed as regards user&#8217;s development.   Less than 50, 000 and melt users after providing service for two years.   BT goes to the market to belong to bad development to lack attractive dualmode cell-phone and channel.   (whether see BT make it confirm / lead to getting blue by cellular telephone, BT not to enter the water, Flat of BT melt, feet of BT. in FMC)  </p>
<p>But an analyst said the melted question can not clearly lie in, and even obscure, sell.  </p>
<p>&#8221; What for users do not know, &#8221;   Picture assorted Tohmatsu David and Tansley in Deloitte, a partner says.   &#8221; They can&#8217;t find out whether it is about cheaper telephone or new service.   That understands scarcely that is being damaged very much.  &#8221; </p>
<p>When eyes of BT wander up and down and check femtocells, the operator says the key component that WiFi that it keeps being devoted to offers as its mobility and to melting, though lackluster user takeup.   </p>
<p>The operator plans a door to sell and demand to melt in earlier 2008 strongly constantly, including the quotation of more broad mobile phone.   [Ed points out: Did not we hear this in the past?  ](whether see BT increase WiFi apparatus, BT melt BT WiFi focus and BT FONs, WiFi solicits, FON cooperation.)  </p>
<p>Only 4 weeks ago, BT melts and serves and launches a kind of anticipated payment to choose with its GSM quietly.   Barclay says this will drive the service to Great Britain and new part of addressable cellular telephone market of the United Kingdom of Northern Ireland, the market is prepaid from 65% of Great Britain and the United Kingdom, Northern Ireland.   </p>
<p>&#8221; We plan to drive and melt to develop through the salary and new mobile phone in advance, new [serve ] planning and a sale new method, &#8221;   Barclay says.   &#8221; The users who we must make learn about the service.  &#8221; </p>

			<content:encoded><![CDATA[<p>Known as the code division multiple access (DS-CDMA) in proper order directly too directly Order last expansion frequency spectrum signal one of method of modulation that send of figure above radio broadcasting.   Expand frequency spectrum according to the direct order, the small stream of the information conveyed is divided into smallly, each one is passed and assigned to to cross a frequency channel of the range.   Close to data signal and a high speed datum and some orders of carrying (know as a cracked code too) It combine together that divide count rate that travel according to.   If the data location is damaged during sending, the surplus cracked code helps the signal to resist and interfere with and enable the initial data to resume.<br />
Form and compare with other spectral course of expansion known as frequency with jumping to expand frequency spectrum in proper order directly, or the code division multiple access (FH-CDMA) jumps Frequency,divide pieces of bandwidth wide range thin slices into into much broadcast frequencies possible.   Usually, the apparatus of frequency jumps to use less power and cheaper, but the performance of DS-CDMA system is usually better and more reliable.   </p>
<p>The first of the expansion frequency spectrum is by the extensive application of those armies, because it is difficult to be resisted and blocked and attempting to do by wideband signal and that found to use.   In recent years, researchers have already transferred their attention to the commercial purpose, especially the wireless network of some areas uses and expands the spectral course.  </p>
