AT&T and Verizon Communications are spending billions of dollars upgrading their networks to deliver Internet Protocol-based TV service to consumers. But most homes today aren't equipped with Ethernet cabling. So one of the problems they face is finding a way to distribute the service to multiple TVs.

Wi-Fi provides a good alternative to Ethernet cabling, but the technology has not provided enough capacity or reliability to be used for anything more than delivering data services.

But we may want to watch Airgo Networks in that space. The company has already been supplying wireless routing companies such as Linksys. Now Airgo says it has tweaked its technology to improve the throughput, range and reliability of the signal enough to deliver high-quality video. Airgo's next-generation chips, called True MIMO Gen3, provide transmission speeds up to 240mbps when tested in Airgo's 6,000-square-foot model home.
