Beware of pricier mobile Internet data plans
September 14th, 2009 | 
Author: Prices for cell phone voice services may be dropping, but consumers are likely to be forced to pay a lot more for mobile Internet data plans in the future.
It’s no secret that the price of voice services for cell phones is falling. Just last week Sprint Nextel announced it was offering a new $69.99 a month, Any Mobile, Anytime plan that allows subscribers to call any cell phone in the U.S., regardless of the carrier, in addition to such things as unlimited text messaging and data services.
Analysts are predicting a price war in the mobile market as national wireless carriers will soon be forced to offer more minutes of voice service or unlimited voice services for equal or lower prices to compete with each other.
To make up for the shortfall in revenue, these analysts also predict that wireless operators will start reconfiguring Internet data service plans to make up the difference.
“Voice revenue is declining for the carriers,” said Charles Golvin, an analyst with Forrester Research. “And the vision for the future is to use data revenue to make up for the shortfall and to kick ARPU (average revenue per user) into growth mode.”

802.11n Wi-Fi standard finally approved
As predicted last month, the IEEE has finally approved the 802.11n high-throughput wireless LAN standard.
Finalization of the new wireless networking standard–which is capable of delivering throughput speeds up to 300 megabits per second (and even higher)–took exactly seven years from the day it was conceived, or six years from the first draft version. The standard has been through a dozen or so draft versions.
News of the ratification broke via a blog post displaying an e-mail sent by Bruce Kraemer, longtime chairman of the 802.11n Task Group, to task group members. There has been no public announcement yet. Update 5:49 p.m. PDT: A press release has been issued.
(The 802.11n Task Group is part of the 802.11 Working Group, which oversees WLAN (wireless local-area network) standards. Task group members include the majority of Wi-Fi chipmakers, software developers, and equipment OEM vendors. Meru Networks, one of the members, posted the blog that broke the news.)
It’s likely, however, that final approval of the standard will be publicly announced by September 15, the date when Meru Networks puts on a public Webcast to provide answers about the ratification.
According to the Wi-Fi Alliance, the group that tests and certifies wireless products to ensure their interoperability, all existing Wi-Fi Certified Draft N wireless products will still work with the final standard.
802.11n offers much higher speeds than the previous, already-ratified 802.11g, which caps at only 54Mbps. Due to the compelling higher speed, most wireless vendors haven been offering 802.11n-based (also known as Wireless-N) products during the past six years and calling them Draft N products. Now the Draft is no more.
According to the Wi-Fi Alliance, most, if not all, of the existing equipment can be upgraded to the final specification via a firmware update. Finally, all future wireless networking products will be compatible with today’s products that have been Wi-Fi-certified.

Google Voice and Gmail are sort of merging
Two new little Google Voice features just made their way into Gmail. A new option lets text messages sent to Google Voice show up as e-mail messages in Gmail. You can reply to messages from Gmail, too, which makes it a nice platform for carrying on a text message conversation.

More on today’s Gmail issue
Gmail’s web interface had a widespread outage earlier today, lasting about 100 minutes. We know how many people rely on Gmail for personal and professional communications, and we take it very seriously when there’s a problem with the service. Thus, right up front, I’d like to apologize to all of you — today’s outage was a Big Deal, and we’re treating it as such. We’ve already thoroughly investigated what happened, and we’re currently compiling a list of things we intend to fix or improve as a result of the investigation.
Here’s what happened: This morning (Pacific Time) we took a small fraction of Gmail’s servers offline to perform routine upgrades. This isn’t in itself a problem — we do this all the time, and Gmail’s web interface runs in many locations and just sends traffic to other locations when one is offline.
However, as we now know, we had slightly underestimated the load which some recent changes (ironically, some designed to improve service availability) placed on the request routers — servers which direct web queries to the appropriate Gmail server for response. At about 12:30 pm Pacific a few of the request routers became overloaded and in effect told the rest of the system “stop sending us traffic, we’re too slow!”. This transferred the load onto the remaining request routers, causing a few more of them to also become overloaded, and within minutes nearly all of the request routers were overloaded. As a result, people couldn’t access Gmail via the web interface because their requests couldn’t be routed to a Gmail server. IMAP/POP access and mail processing continued to work normally because these requests don’t use the same routers.
The Gmail engineering team was alerted to the failures within seconds (we take monitoring very seriously). After establishing that the core problem was insufficient available capacity, the team brought a LOT of additional request routers online (flexible capacity is one of the advantages of Google’s architecture), distributed the traffic across the request routers, and the Gmail web interface came back online.
What’s next: We’ve turned our full attention to helping ensure this kind of event doesn’t happen again. Some of the actions are straightforward and are already done — for example, increasing request router capacity well beyond peak demand to provide headroom. Some of the actions are more subtle — for example, we have concluded that request routers don’t have sufficient failure isolation (i.e. if there’s a problem in one datacenter, it shouldn’t affect servers in another datacenter) and do not degrade gracefully (e.g. if many request routers are overloaded simultaneously, they all should just get slower instead of refusing to accept traffic and shifting their load). We’ll be hard at work over the next few weeks implementing these and other Gmail reliability improvements — Gmail remains more than 99.9% available to all users, and we’re committed to keeping events like today’s notable for their rarity.

Sony shipping Chrome on Vaios
Google promised earlier this year that a major computer maker would start to ship its Chrome browser.
Sony’s the one.
Sony’s Vaio line has begun carrying the browser in the U.S., the Financial Times reported late Monday.
According to a Dow Jones report, all Vaio-branded PCs are now using Chrome as their default browser. A Sony representative told Dow Jones that there are no plans to add Chrome to Vaios outside the U.S.
Vaios will continue to come with Microsoft’s Internet Explorer in tandem.
The Financial Times also reported that other companies are in talks with Google about Chrome and that the browser will also be promoted to Internet users who download RealNetworks’ RealPlayer media-streaming software. Google has previously said it’s in discussions with Dell about bundling the software.
To date–a day before the first anniversary of its launch on September 2, 2008–Chrome has around 30 million active users or around 3 percent of the global market. This makes it the fourth most-popular browser after Internet Explorer, Mozilla’s FireFox, and Apple’s Safari.
