System Overview
GigAccess
TM
is WaveIP’s wireless point-to-point and point-to-multipoint broadband
communication system. The basic subsystem is composed of a single sector, which consists of an
AU (Access Unit) and up to 64 SUs (Subscriber Units). Each sector is a stand-alone
communication network operating on a star topology with a gateway to the WAN, which allows
two-way communication between the SUs and the WAN via the AU. A Sector may be divided into
sub sectors, which are consecutive to the SUs within the sector.
A sector may include a BC (Base Controller) as an option. The BC is based on a PC and is
connecting to the AUs via the Ethernet. The interface to the BC is a 10/100 BASE-T, Ethernet
port, which provide an NMS (Network Management System) that can be integrated through an
SNMP interface to high level NMS of the service provider . Its main purpose is to configure the
AUs and SUs with SLA (Service Level Agreement). Once the AU was configured, the
configuration file is burned into an internal FLASH memory and the AU can run autonomic without
the need of a BC (stand alone configuration).
Figure 1-1 depicts a general description of a typical sector in the GigAccess™ system.

The sector uses a single radio channel frequency that carries up to 11 MBPS of data throughput.
The data bandwidth is divided between the traffic from the AU to SUs (downstream) and the traffic
from the SUs to AU (upstream). GigAccess™ utilizes Time Domain Duplex (TDD) technique in
