Motorola is one of the earliest of the major telecom companies to place all of its WiMax bets on the 802.16e version of the technology, instead of the 802.16d standard for fixed WiMax. Motorola last year announced its "MotoWi4" umbrella brand for an array of broadband wireless technologies that includes mesh WiFi networks, WiMax, and the Canopy wireless technology for unlicensed spectrum. It also launched a partnership with Sprint Nextel Corp. in which Motorola will develop WiMax handsets and infrastructure for the broadband wireless network that Sprint plans to build over the next couple of years. Field trials are expected to start later this year. Widespread availability of Wimax is not expected until 2009. Wimax speeds are expecting to be about 15mbps for mobile system and 40mbps for fixed position systems.
Upgrades of cellphone EVDO technology could allow average download speeds starting in 2007 of between 1.3mbps and 2.4mbps and upload speeds between 210kbps and 432kbps This is three times better than what is available today.
