xMax

For the Xmax referring to loudspeaker driver maximum excursion, see Thiele/Small.

xMax developed by xG Technology, Inc. is a cognitive radio based mobile VoIP and computer networking system operating in the license-free ISM 900 MHz band (902-928 MHz). xMax is built upon an end-to-end Internet Protocol (IP) system infrastructure that includes a line of base stations, mobile switching centers (MSC), handsets and modems.

Performance claims

A press report was published in 2005 quoting inventor Joseph Bobier.[1] The technology was said to compete with WiMax, but details were initially not disclosed.[2] By 2006, the company announced it had "completed" the technology after six years of development.[3] In 2009, a blogger wrote that he witnessed a xMax mobile VoIP pilot network operated by the company in Fort Lauderdale: "xMax worked well and is real. When you realize that this company may have found a way to take a frequency riddled with wireless garbage and turn it into a fully functioning wireless voice and data network you start to see how much of a game changer this could be for the wireless industry."[4]

From 2007 through 2009 Phil Karn published some analysis of the technology claims.[5]
