"The only difference between Wi-Fi that's selling today for low single digits and us, is that they've sold a billion of them," Grodzinski said.

Specialized functions such as docking and video streaming are small opportunities compared with faster wireless LANs, said Farpoint Group analyst Craig Mathias. The 60GHz band is irresistible because it has between 7MHz and 9MHz of unlicensed spectrum available in it, regardless of any limitations on network range, he said.

"The real money is out there in high-performance wireless LANs. You can never have enough network capacity," Mathias said.

He expects WiGig capability to be sold as one more form of Wi-Fi, with users eventually being able to move onto 60GHz without even knowing.

"This idea of tri-band is very powerful and I think you're probably going to see a significant emphasis on that approach," Mathias said. "It'll all eventually live under the Wi-Fi umbrella, whether the Wi-Fi Alliance wants it to or not," he added.
