Hello all,

Four more contributions for system requirements are available on our web site
(http://grouper.ieee.org/groups/802/16/sysreq/index.html).  Please review them
and post your comments to the email reflector (stds-802-16@ieee.org).

   The Network Topology of Point to Multipoint Radio Systems
   Scott Marin
Broadband fixed wireless access systems are being planned for delivery of
voice, data, and video services to subscribers. Point-to- multipoint radios
have emerged as the principle approach to implementing these systems. This
paper defines microwave point-to-multipoint radio systems in terms of network
topologies so that appropriate protocols can be selected by the 802.16 working

   802.16 Services and Applications
   Scott Marin
Broadband fixed wireless access systems are being planned for delivery of
voice, data, and video services to subscribers. The planned data rates range
from POTS (64 kbps) to over DS3 (45 Mbps) rates. This document proposes some
of the services and applications that the customers of Bosch Telecom consider
important for business success in services such as the local multipoint
distribution service (LMDS).

   Quality of Service
   Scott Marin
Broadband fixed wireless access systems are planned for multi-service
applications that may have different quality of service categories. Categories
and parameters are proposed.  The ITU 27,500 km hypothetical reference path
and parameters from existing standards are used to allocate parameters to the
access section of the reference path.  Some parameters are derived where no
standard has provided an access section allocation.

   Interface to MAC and LLC Protocols
   George Fishel
Broadband fixed wireless access systems are under development to deliver
voice, data and video for residential and commercial applications.
Interoperability between various vendors' equipment, other IEEE 802 IP
systems, and protocols such as ATM will be imperative for commercial success
of the standard. Interoperability must be maintained at the physical layer,
MAC layer, and LLC layer. Transport of real-time voice and video requires
isochronous communications, provided by a QoS mechanism, which must
interoperate between various systems and applications. This document proposes
considerations for interoperability at various layers.
