Motorola's USBw 200 WiMAX adapter takes less power

If you're inhabiting one of the few but increasingly common localities with WiMAX internets beaming through the airwaves, you're probably looking for the least bulky and most efficient way to get connected. Motorola's latest doesn't look particularly more svelte than its previous USBw 100, but the USBw 200 is more efficient, requiring less than 1.5 watts of power despite the new "power boost" mode to connect more quickly to networks.
Like its predecessor, it supports 2.3, 2.5, and 3.5GHz bands, and now includes Windows XP and Vista drivers on the device itself, so no pesky installation CD is required. No word on pricing or availability, but those figures will be largely be left to the discretion of wireless providers anyhow.
With this capability the WiMAX CPEi 725 and USBw 200 WiMAX devices will automatically transmit on the antenna that is receiving the stronger signal, providing subscribers with a better connection to the network while allowing operators to reduce base station infrastructure requirements. The CPEi 725, available in the 2.5GHz band, and the USBw 200, available for the 2.3, 2.5 and 3.5GHz bands, can be updated over-the-air. Both products initially will be available in Q4 of 2009.
Motorola’s CPEi 725 features a balanced blend of integrated design, data and voice access ports, high gain antennas to offer the best possible signal strength and a highly sensitive receiver that exceeds the WiMAX Forum®’s specified receiver sensitivity requirements across all modulation schemes. In addition, the CPEi 725 features a single Analog Terminal Adaptor voice port to streamline the subscriber experience when connecting voice equipment.
The CPEi 725 has unique design advantages which improve network performance and end-user experience while reducing the total cost of operations. Leveraging Multiple Input Multiple Output (MIMO), diversity techniques, and excellent receiver sensitivity, these devices provide increased throughput, optimize utilization of system resources, and reduce the number of access points required to provide service.
A unique power boost during network entry feature will make it even easier to connect to operator networks and expand footprints to a wider area. Finally, the USBw 200 delivers this improved experience while using less power – drawing less than 1.5 watts at peak power.
