Summary

In this project CWINS has been funded to purchase equipment that will significantly enhance its research activities in wireless networks for multi-media applications.

The principle feature of this equipment enhancement is an experimental wireless LAN testbed that will be used to serve as a test environment for multi-layer design and performance monitoring. In this testbed, researchers working at all protocol layers of the network will conduct their research to evaluate the impact of wireless broadband access on the design and performance analysis. Multimedia services such as voice, text and image streams will be provided to terminals dispersed over the geographical area covered by the testbed.

The planned equipment includes a network analyzer, spectrum analyzer, and RF power meter for physical layer scenario development up to 50GHz, which includes all bands currently considered for UWB systems. Other planned equipment includes wireless access points, a central router and switch, network management and monitoring software, laptop computers, PDAs, wireless LAN IP phones, and head-mounted displays as well as a traffic generator and protocol analyzers for packet generation and performance monitoring. The wireless LAN Network Interface Cards (NICs) include IEEE 802.11 as well as Bluetooth cards for both laptop computers and PDAs.
