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.

TWC WiFi in Los Angeles County

TWC WiFi in Orange County

Time Warner Cable has unveiled free Wi-Fi service for their broadband customers on-the-go in selected portions of Los Angeles and Orange counties.

TWC WiFi comes free for Road Runner customers.  Others can access the network for $2.95 for one hour, $6.95 for one day, $19.95 for a week, or $49.95 a month, which is at least as much as the price of a traditional Road Runner account.

The first phase of the $15 million dollar wireless network covers 40 square miles, including downtown Los Angeles, Newport Beach, Santa Ana, Venice Beach, and West Hollywood.

That’s only a tiny fraction of Los Angeles County’s total size, encompassing more than 4,700 square miles, but the cable operator promises it will be expanding the wireless network to cover Westside coastal communities and more of Orange County.

Los Angeles joins New York City as Time Warner’s second Wi-Fi-enabled city.  The cable company is introducing Wi-Fi service to help improve the perceived value of the company’s broadband product.

Not satisfied with relying on the U.S. Department of Justice to protect the competitive marketplace for cell phone service, Sprint Nextel today brought suit against AT&T, Inc., AT&T Mobility, Deutsche Telekom and T-Mobile seeking to block the proposed acquisition as a violation of Section 7 of the Clayton Act. The lawsuit was filed in federal court in the District of Columbia as a related case to the Department of Justice’s (DOJ) suit against the proposed acquisition.  It has been assigned to the same judge handling the Justice Department’s own lawsuit — Judge Ellen S. Huvelle.

“Sprint opposes AT&T’s proposed takeover of T-Mobile,” said Susan Z. Haller, vice president-Litigation, Sprint. “With today’s legal action, we are continuing that advocacy on behalf of consumers and competition, and expect to contribute our expertise and resources in proving that the proposed transaction is illegal.”

Sprint’s lawsuit focuses on the competitive and consumer harms which would result from a takeover of T-Mobile by AT&T. The proposed takeover would:

• Harm retail consumers and corporate customers by causing higher prices and less innovation;
• Entrench the duopoly control of AT&T and Verizon, the two “Ma Bell” descendants, of the almost one-quarter of a trillion dollar wireless market. As a result of the transaction, AT&T and Verizon would control more than three-quarters of that market and 90 percent of the profits;
• Harm Sprint and the other independent wireless carriers. If the transaction were to be allowed, a combined AT&T and T-Mobile would have the ability to use its control over backhaul, roaming and spectrum, and its increased market position to exclude competitors, raise their costs, restrict their access to handsets, damage their businesses and ultimately to lessen competition.

Sprint believes that in a marketplace dominated by AT&T and Verizon Wireless, the two largest players would likely collude on pricing and terms of service rather than compete heavily against one-another.  Sprint’s assumptions may already be true, considering both companies largely charge near-identical prices for service.

While Sprint proceeds with its own legal action, squabbling has broken out over whether or not AT&T so carefully crafted the terms and conditions of their $6 billion “breakup fee,” payable to T-Mobile USA if the merger fails, that it almost guarantees AT&T will never have to pay it.

“Under its agreement with Deutsche Telekom, the deal is only valid if the acquisition receives regulatory approval within a certain time frame,” an anonymous source told Reuters. “Also, the agreement could become invalid if regulatory conditions for the sale push the value of T-Mobile USA below a certain level.”

T-Mobile, unsurprisingly, disagrees with that characterization.

A Deutsche Telekom spokesman said Tuesday that AT&T could retreat from the transaction if the concessions necessary to get approval amount to more than $7.8 billion, but added Deutsche Telekom would still be entitled to receive the break-up fee package, which includes cash and wireless spectrum.

Canada’s largest privately owned telecommunications provider is getting into the mobile broadband business.

EastLink, which owns cable systems in communities across nine provinces, is constructing its own mobile phone and data network set to launch in 2012.  Part of that network will be its own competitive wireless mobile broadband service.

EastLink is using licensed wireless spectrum acquired in a 2008 federal auction which will allow it to provide cell service in Newfoundland, New Brunswick, north and southwest Ontario, and the metropolitan region of Grand Prairie, Alta.  But its first priority is delivering service on Prince Edward Island and in Nova Scotia, where EastLink is based.

“With this network evolution, our customers will be able to work and communicate more reliably and faster than ever before,” said Matthew MacLellan, president of EastLink Wireless.

EastLink subsidiary Delta Cable delivers cable service in western Canada.

EastLink’s new wireless network will use HSPA technology, presumably at the speeds most common in Canada — 21 or 42Mbps.  Ericsson is providing the equipment for the network.

EastLink has nearly a half-million customers, a tiny number in comparison to market leaders Bell, Rogers, and Telus.  But the company has a reputation for delivering advanced service, and is well-regarded in Atlantic Canada, especially for delivering Internet at speeds up to 100Mbps.

“They have a very strong reputation so they’ll be likely to shake up the market down there,” Brownlee Thomas, principal analyst at Forrester Research Inc., told The Wire Report.

EastLink’s primary focus is on its Canadian subscribers, but the company has also investments in Bermuda, and its subsidiary Delta Cable delivers service to one American community — the enclave of Point Roberts, Washington, located south of Delta, British Columbia.
