Steve Perlman, the creator of the defunct game-streaming service OnLive, claims he has the answer to slow wireless service. pWave is a new type of wireless antenna that creates a miniature “bubble” of wireless connectivity around every device, solving congestion even in busy areas like sports stadiums and city centers. Perlman calls these bubbles pCells, and today his company Artemis is launching its ambitious attempt to reinvent the wireless network.
