Abstract
This talk will describe the Wireless ATM Adaptive Voice/Data Networks
project at the University of Kansas. The objective of this project is
the implementation and demonstration of a complete adaptive voice/data
(AVD) network, including switches and terminal units, based on
wireless asynchronous transfer mode (ATM) technology. This network
will serve as a testbed for investigation into the delivery of voice,
images, and data to remote users using highly interoperable ATM
technology. Dynamic bandwidth allocation algorithms using low bit
rate speech coding based on the Sinusoidal Transform Coder are used in
the ATM wireless environment. Existing ATM standards are the basis
for network control and management were possible, and research into
extending the technology into the narrowband arena is being performed.
A testbed to evaluate the use of the bit-rate adaptive characteristics
of the Sinusoidal Transform Coder (STC) as a means of congestion
control for voice/data networks is being designed and built. The
narrowband network is interfaced to other ATM facilities such as the
MAGIC gigabit testbed, the ACTS ATM Internetwork (AAI), and the
Rapidly Deployable Radio Network (RDRN), to demonstrate
interoperability.
