Is Wi-Fi the Future of Mobile Internet? Jeff Thompson, the CEO of Towerstream has been asking this question lately. And after seeing the results of a test Wi-Fi project in mid-town Manhattan, Thompson keeps coming back to the same answer: yes.

Thompson’s company has been testing the Wi-Fi network since early summer and has recorded days of more than 1 terabyte in usage and 21 million connections in one quarter. This is in one area of Manhattan while AT&T racked up 68.1 million Wi-Fi connections in the second quarter from its more than 20,000 hotspots nationwide.

What it suggests is that even with 4G on the way, carriers cannot keep up with the looming demand for mobile broadband. And as even more people adopt smartphones, which generate an estimated 50 times more data usage than feature phones, the crunch will only continue. Current projections are that half of U.S. mobile subscribers will have a smartphone by the end of next year.

“What we’re learning is there is a huge amount of demand for Wi-Fi devices and what we’re seeing in the first three months of using the Wi-Fi network is the dramatic increase of handsets jumping on the network,” Thompson said. “All of these devices are not getting enough of what they need from 3G networks. Wi-Fi has critical mass.”

And that’s where Towerstream comes in. The company is testing the Wi-Fi network using 802.11 N technology with powerful hardware from Ruckus Wireless that extend a wireless radio’s reach to 1,200 feet. Combined with Towerstream’s own broadband network, which can pump out 200 megabits per second, the company has a system that is faster and more capacious than cellular networks.

While Towerstream hasn’t decided what it will do next after the Wi-Fi test, the company is considering building more networks and selling wholesale access to carriers who need to offload data usage. Some carriers such as AT&T are relying on their own Wi-Fi hotspots while others like Verizon have struck deals with Boingo to offer more wireless access. And all the carriers are turning to femtocells and UMA technology to extend coverage in home. But they’re aware that it won’t be enough, something that was very apparent at the Mobile World Congress in February.

Offering a wholesale option for Wi-Fi offload for carriers, especially in dense areas of big cities like New York, San Francisco, Chicago or Los Angeles, holds special promise for improving network connectivity. Overworked 3G networks are already a headache in places like New York and San Francisco but it could be a more common problem elsewhere as usage goes up. Even with a network of hotspots, having an option to light up a general problem area could go a long way in bringing down complaints and keeping pace with demand.

Thompson said he’s talking to carriers and he said cable operators might also be potential customers. Comcast recently rolled out 2,000 free Wi-Fi hotspots for its Xfinity customers in New Jersey, Philadelphia and Delaware while Cablevision has launched Wi-Fi hotspots around the greater New York area. The growing reliance on Wi-Fi has implications for not just Towerstream but Wi-Fi networking vendors such as Ruckus, which provided the gear for Towerstream, and  for BelAir Networks, which is building wireless base stations for wireless operators and cable companies such as Cablevision. Though much of the talk is turning to 4G these days, Wi-Fi is increasingly looking like a critical way to keep the mobile broadband boom alive.

  1. Too bad 1200 feet is only .2 miles. It would take a lot of hotspots to cover areas. Definitely works great at a stadium with a ton of people to handle the bandwidth. I do enjoy the free wifi at Starbucks and such, but being on a public wifi can be a little dangerous. I agree Wifi is here to stay, that is until something else that could potentially take it over, but that is not the case yet.

  2. i understand the benefits of wifi at my home, workplace, etc. and also can see why cable companies might want to offer city wide wifi as an incentive for customers.

    but is does it really make more sense for the carriers such as AT&T or verizon to use WIFI instead of deploying picocells, mircocells or whatever is the latest fad in tiny cellular towers? it would certainly keep things a lot simpler for their customers. as smartphones become more commonplace the customers will be less sophisticated and many may not even understand how the wifi capability on there phones work. also with the proliferation of MIFI devices and tethering becoming more common a lot of wifi connections are going to loop back onto the cell networks anyways.

  3. If only all those ISP and cable providers could just partner with Fon (http://www.fon.com/en/) like it is done in Europe and Asia (BT, SFR, etc.), it would be simpler for all customers.

Other radio standards won’t go away (Atheros makes chips for many of them) and Qualcomm will likely begin offering even more highly integrated chips that combine application processors, cellular radio technology, Wi-Fi and other flavors. Mollenkopf mentioned that even cellular operators will rely more on Wi-Fi as they deploy their 4G networks, to meet the demand for bandwidth while saving their scare spectrum resources. For example, Towerstream said it has seen days where usage on a single metro Wi-Fi hot zone in Manhattan has exceeded a terabyte of traffic. [...]
