AT&T flipped the switch Sunday on its new 4G-LTE wireless data network, and the resulting next-generation wireless speeds now available to customers in Atlanta, Chicago, Dallas, Houston and San Antonio, Texas are impressive, averaging 23.6Mbps on the download and 15.2Mbps for uploads during a three-day test.

Mobile World reports initial testing by Signals Research in Houston delivered a peak data rate of a massive 61.1Mbps.  The researchers transferred nearly 90GB of data back and forth during the weekend tests, almost always at data rates above 5Mbps.

AT&T intends to compliment its existing “4G” HSPA+ network with a gradual rollout of LTE service in their major markets, eventually covering 44,000 nodes over a three-year period.

AT&T will first introduce its LTE service to wireless mobile broadband customers who will find the USB modems on sale with a two-year service commitment.  Support for the network on smartphones will come later.

A few important points to consider before becoming too excited with AT&T’s speed ratings:

1. Signals Research conducted the tests on an effectively empty network.  Since AT&T hasn’t started selling LTE-capable smartphones yet, the only ones using the network are AT&T’s mobile broadband customers, most of whom are using AT&T’s older HSPA+ service.  AT&T doesn’t guarantee any particular speed, and it’s a safe bet speeds will slow considerably when smartphone customers eventually pile on board.
2. That speed comes at a significant price.  AT&T is charging $50 a month for mobile broadband service with a 5GB usage cap.  Each additional gigabyte runs $10.  Signals Research is lucky they didn’t pay AT&T the going rate during their tests.  That 90GB of data would result in a bill from AT&T amounting to $50 for service, and $850 in overlimit penalties.

AT&T and Verizon: The Doublemint Twins of Wireless

Mirroring AT&T’s announcement last month that it would begin implementing speed throttles for wireless unlimited data plan customers who are among the “top 5% of users,” Verizon Wireless quietly made changes last week allowing the company to throttle its own unlimited data plan “heavy users” who consume more than 2GB of usage per month on its 3G network.

But Verizon claims it isn’t actually throttling the speeds of customers, it is simply engaging in “network optimization practices” and using “network intelligence” to reduce speeds (sometimes to near-dial-up) while connected to a “congested cell site.”

That will prove a distinction without much difference to customers who rely on 3G data usage using cell sites Verizon deems congested.  They may also find the time spent in Verizon’s penalty box unusually long.

“You may experience [reduced speeds] for the remainder of your then current bill cycle and immediately following bill cycle,” Verizon’s FAQ states.

That can mean customers paying $30 a month for an “unlimited data plan” may find 3G usage a very slow experience for a maximum of two months before they are off Verizon’s throttle list.

The new speed throttle policy began Sept. 15.  Verizon:

Network Optimization practices and throttling is network intelligence.  With throttling, your wireless data speed is reduced for your entire cycle, 100% of the time, no matter where you are. Network Optimization is based on the theory that all customers should have the best network possible, and if you’re not causing congestion for others, even if you are using a high amount of data, your connection speed should be as good as possible. So, if you’re in the top 5% of data users, your speed is reduced only when you are connected to a congested cell site. Once you are no longer connected to a congested site, your speed will return to normal. This could mean a matter of seconds or hours, depending on your location and time of day.

Verizon has not said exactly how many of its cell sites it deems as “congested,” at what times that congestion is most likely to occur, and admits there is currently no way customers can learn when they are connected to a congested site so they can make an informed decision about their usage.

But the company does say customers can avoid the penalty:

1. Upgrade to a 4G phone and hope for good 4G LTE coverage.  Customers using Verizon’s 4G network are not currently subject to a speed penalty for “excessive use.”
2. “Upgrade” to a tiered data plan with usage allowances.  Verizon will not throttle the speeds of customers who are not on unlimited data plans.
3. Reduce your data usage, especially in areas where congestion is likely.

Choke collars are in season at AT&T and Verizon Wireless, leaving Sprint's unlimited service looking more consumer-friendly by the day.

Those suggestions require potentially pricey new handsets, require customers to abandon their existing unlimited data usage plan, or simply get you thinking twice before launching a data session, fearing being grounded for up to two months with a dramatically reduced level of service.

The biggest impact of the network speed throttles will be among data-heavy iPhone users.  Apple’s iPhone doesn’t support 4G, and is likely to continue to rely on 3G network coverage when the next version of the popular phone is introduced in October.  Ultimately, Verizon’s new policy means iPhone devotees using more than 2GB per month may have to abandon their phone or their unlimited data plan if they want to avoid the throttle.

Verizon also found a way to keep customers from canceling penalty-free, noting contract changes that reserved the right to implement network management techniques were made in February.  The 60-day window for the “materially-adverse” contract change cancellation policy expired in April.  Verizon:

By alerting customers in February 2011, and including the notice in our terms and conditions as of February 3, 2011, we made sure customers knew we began reserving the right to implement Network Optimization practices.  In February 2011, we began alerting customers:

• Data Management – (note: now named “Network Optimization” to more accurately describe the tools) – Verizon Wireless may reduce data throughput speeds in a given bill cycle for customers who use an extraordinary amount of data and fall within the top 5% of data users.  The reduction will only apply to those using congested cell sites and can last for the remainder of the current and immediately following billing cycle.  The reductions will only apply when appropriate in locations and at times of peak demand.
• Data Optimization – (note: now named “Video Optimization” to more accurately describe its function) – Verizon Wireless is implementing optimization and transcoding technologies in its network to transmit data files in a more efficient manner to allow available network capacity to benefit the greatest number of users, and although unlikely, the process may minimally impact the appearance of the file as displayed on the mobile device.

Interestingly, AT&T’s own speed throttle penalty was estimated to kick in after 4GB of usage, not the 2GB Verizon is using as its benchmark for “network optimization.”  Verizon also says customers with their Mobile Hotspot feature will find that usage exempted from counting towards the 2GB threshold.

Verizon has opened up a new web page explaining the throttling policy.

Verizon Wireless has announced a new $50 unlimited talk, text, and web prepaid plan for price sensitive new customers who don’t mind being stuck with a lower-end feature phone.

The new Verizon Unleashed unlimited plan has been test-marketed since April to prepaid customers in southern California and Florida, but will now be available nationwide from Verizon stores, Best Buy, Wal-Mart and Target.

Although existing Verizon Wireless prepaid customers may be able to sign up for the plan on their existing phones, new customers in test markets were limited to a selection of just a handful of “feature phones” that make web use and texting cumbersome:

• LG Cosmos™ 2 — Now into its second generation, this basic feature phone slightly improved its slide-out keyboard.  The phone was rated “adequate” for an entry-level feature phone, but CNET’s detailed review notes it lacks 3G EV-DO service.  That means you will be web browsing on Verizon’s painfully slow 1xRTT data network.  Verizon has no worries customers using this phone will chew up a lot of wireless data.  Customers rated the build quality as adequate, but found the keys on the first generation of this phone did tend to wear out with a lot of use.  It’s a true “throwaway” phone once the warranty expires.  Repairs always cost more than buying a new phone.  Verizon’s website prices the phone at a stiff $189.99 for month-to-month customers, but it will probably remain priced at around $99.99 for prepaid customers choosing the Unleashed plan.
• LG Accolade™ — A real workhorse basic phone for Verizon Wireless, the Accolade is much better for making and receiving calls than doing anything with texting or web use.  The phone has no QWERTY keyboard to type on, and no 3G service either, so its usefulness for data and texting is extremely limited.  But it is cheap, routinely selling for under $40.  CNET has a video review.  We suspect this phone will not be major part of the nationwide rollout of Unleashed, as Verizon appears to have discontinued it recently.
• Pantech Caper — A front facing tiny keyboard features prominently on this phone, which would have been considered cutting edge five years ago.  Now, it’s considered a ho-hum “feature phone” for the non-smartphone crowd.  It received a fair rating from most reviewers, with the biggest complaints coming from unintentional pocket dialing and button pressing, and a lousy built-in camera.  No 3G service.  The Caper also won’t win any awards for its ergonomics.  Verizon Wireless had been selling this phone in test markets for $80 earlier this year.  CNET’s video review is here.

There is a good chance a few different, more current feature phones will be introduced for the Unleashed plan later this week.  But they will all likely dispense with support for 3G service and lack features many customers increasingly seek on smartphones.

Verizon Wireless has traditionally done poorly in the prepaid market, because its plans are considerably more expensive that those offered by competitors, especially T-Mobile and Sprint.  Verizon Wireless had been charging $95 a month for unlimited talk/text prepaid service plus $0.99 per day for web use.  At those prices, Verizon has been losing prepaid customers, now down to 4.4 million.  Many of those customers fled to providers like Sprint’s Virgin Mobile, which saw a 23 percent increase in its customers, which now number 13.8 million.

Verizon’s $50 unlimited plan matches AT&T’s $50 prepaid unlimited GoPhone plan.  Analysts suggest both companies have set prices (and limitations on the phones that work with the plans) at a level that allows them to compete with lower-priced rivals, but does not encourage their contract customers to switch to a cheaper prepaid plan.

For data-hungry smartphone users, there is little here to persuade anyone to downgrade to a $50 prepaid plan.

A new study from the University of Michigan suggests one U.S. cell phone company is intentionally throttling cell phone speeds by as much as 50 percent, potentially to engage in “deep packet inspection” of their customers’ wireless traffic.

The researchers also found bad network management may be costing you up to 10 percent of your daily battery life.

The study, published by a team of researchers at the university and Microsoft Research, relied on nearly 400 volunteers running a diagnostic application while using 107 wireless providers around the world.  Researchers found company policies at several carriers in conflict with practices guaranteeing the fastest wireless data speeds, maximum battery life, and protection from malware and other hacker actions like IP spoofing.

The researchers refused to name the biggest offending carriers, citing legal reasons, but rang the alarm that network performance and security was clearly hampered by management decisions designed to keep costs down and maximize company network efficiency, at the expense of the quality of your service.  Among the conclusions:

• Microsoft engineer Ming Zhang believes the one U.S. carrier with dramatically reduced speed performance is probably using “deep packet inspection” techniques to analyze what individual customers are doing with their wireless connections.  The overhead from that inspection process is implicated in reduced speeds and performance;
• At least 11 wireless carriers are hurriedly shutting down TCP data connections that applications want to leave open in order to communicate on the network.  When an app discovers the data connection has been closed, it has to request a new connection, wasting up to 10 percent of daily battery life;
• Four of 60 cellular networks allow IP spoofing, which can make hosts vulnerable to scanning and battery draining attacks even though they are behind a firewall.

Better days: AT&T's BlackBerry Curve, circa 2007

The prevalence of unlimited wireless data plans may have been an important factor in the American consumer’s move away from Research in Motion’s (RIM) former superstar BlackBerry, according to a company official.

Responding to questions about its falling market share in the U.S., Patrick Spence, the managing director of regional marketing at RIM pointed to unlimited usage plans as one potential way the competition got a leg up on their devices.

“In the United States, they’ve had flat rate data pricing for a long time, which has meant users haven’t had to worry about how they are using their smartphones,” Spence said.

He noted Americans love for wireless data has forced carriers to launch 4G upgrades in advance of other markets where 3G remains the fastest available standard.

The Guardian’s Charles Arthur gave RIM’s Patrick Spence a challenging series of questions about RIM’s ongoing loss of market share, and why the company is forcing BlackBerry owners to cope through two major platform upgrades in the coming months. (11 minutes)

Spence said the dynamics of unlimited data have inspired a change in the types of devices used in the United States, namely not necessarily those carrying the BlackBerry brand.

As carriers end unlimited data, Spence predicts users will likely change their behavior in concert with new data plan limits as low as 200MB per month.

Where data limits prevail, BlackBerry devices seem to do better.  Spence touted the fact BlackBerry phones have now achieved number one status in Africa and countries in the Middle East like Saudi Arabia, displacing troubled Nokia.

Spence warned tech reporters not to extrapolate American marketplace trends as foreshadowing developments in the rest of the world.  One reason for that, according to Spence, has been the unlimited data plan, now being replaced with usage based billing or usage-capped plans.

BlackBerry phones have had a difficult time competing with the iconic Apple iPhone, as well as Android-based smartphones on offer from virtually every wireless carrier.  BlackBerry devices, once deemed the most advanced phones in the market, have lost quite a bit of luster in the last four years, particularly after the arrival of iPhone.

As a result, RIM has been engaged in serious cost-cutting, announcing job cuts of some 2,000 employees recently.  The company hopes to spring back with a series of platform upgrades and new phones, dubbed “superphones” by RIM, to regain market share.

It cannot come soon enough, as RIM lost another four percent of market share in just the past four months.  comScore suggests RIM phones now have just 21.7 percent of the smartphone market.  Only Microsoft and Nokia are doing worse.  Most of the BlackBerry fan base are moving to Android-based smartphones instead as their contracts come up for renewal, particularly those made by Samsung.  The Korean manufacturer now manufactures one of every four smartphones Americans own.

As of July 2011, RIM has 7.6 percent of the market share in the United States.

BlackBerry phones have fewer challenges overseas, and the devices remain very popular among younger users in the United Kingdom, parts of western Europe, Africa, and the Middle East.  That has been a mixed blessing for RIM in England, where the phone has been  implicated as the device of choice for looters during riots earlier this month.
