For example, this means that if you are an AT&T customer in the U.S., you will not only have access to AT&T's 30,000 wireless hot spots here at home, but you might also be able to roam onto Orange's or O2's hot spots in Europe. (AT&T already offers some roaming in other countries, but these standards could simplify this process for subscribers and carriers.). For consumers, seamless roaming onto carrier Wi-Fi networks means that they'll likely get faster Net connections in places where a typical cellular network may be overloaded: Think an NFL football stadium on game day or Times Square during the holidays. With the roaming arrangements among foreign operators, it could mean paying a much reduced data roaming fee while traveling.

And for carriers, the seamless Wi-Fi connections relieve congestion and lower their costs, especially in places that can be overwhelmed with data, The need for additional network capacity is very real, Just ask any AT&T iPhone customer in New York City and San Francisco over the past few years, And even Verizon Wireless, which has traditionally managed its network resources well and is ahead of the competition in deploying retro circles mid century modern background iphone case more efficient 4G LTE technology, says more network capacity is needed..

The wireless capacity crunch But getting that capacity isn't easy. Carriers can only slice and dice their existing spectrum so much. Some carriers, like AT&T and Verizon, are trying to acquire more spectrum from other carriers or companies, such as cable operators, which bought spectrum in previous auctions. The Federal Communications Commission has promised to identify, clear, and auction off more wireless spectrum, but that process has been slow and auctions for new spectrum are still years away.

Wi-Fi offers a more immediate relief to carriers already in a crunch, "Many networks are straining to keep up demand from subscribers with iPhones and Android smartphones," said Craig Mathias, a principal analyst at the Fairpoint Group, "They need to offload traffic in high demand areas, And the best way to do that is through Wi-Fi, And Hostpot 2.0 addresses many of the issues associated with making the retro circles mid century modern background iphone case use of Wi-Fi transparent to end users.", AT&T, which has faced some of the biggest issues with network congestion, has been pushing its Wi-Fi offload strategy the past couple of years, As mentioned earlier, the company has built Wi-Fi hot zones in several cities, and it plans to continue building others, It has more than 30,000 hot spots around the U.S, in Starbucks coffee shops and other retail locations..

And the program has been growing by leaps and bounds. Since 2008 there's been a 60 percent growth in usage. And the company noted in its most recent earnings that access to AT&T's Wi-Fi network tripled in 2011 compared to 2010. AT&T customers made more than 1.2 billion connections to its Wi-Fi hot spots in 2011 or more than 3 million connections per day. Even though these growth figures are impressive, AT&T is still only offloading a fraction of its traffic to Wi-Fi today. These standards could help AT&T and other carriers leverage these Wi-Fi networks even more.
