A testbed has been constructed to evaluate node architectures that sup
port multimedia applications and services across a wireless network. U
sing this testbed, a low bitrate subband video compression algorithm h
as been prototyped in a field programmable gate array (FPGA) and evalu
ated for video networking across bandwidth-limited RF channels. A radi
o interface has been prototyped in an FPGA and a common applications p
rogramming interface (API) has been developed to allow experimentation
with multiple radios. This testbed has been used to evaluate node per
formance under two different wireless applications: 1) simultaneous vi
deo and data networking (VTALK) and 2) TCP/IP utilities such as FTP an
d telnet. Based on this evaluation, the design of a battery-operated h
igh throughput wireless multimedia node is presented.
