Chapter 1 Introduction
The Safari Network TM SR-7100 System offers unique
capabilities that make it an extremely versatile wireless
communications solution. Whether you have a single
point-to-point application or a sophisticated multi-point
data network, the Safari Network can support your
applications and requirements.
System Overview
The Safari Network is based on a Star topology cellular
architecture. It supports simultaneous packet and circuit
switched data communication. The Safari Network
consists of three major components:
Network Control Unit (NCU)
The NCU acts as the overall controller of the Safari
Network, ensuring the most effective allocation of
network resources, and providing a single point of
control for all network components. The NCU also
acts as the gateway between the Safari Network and
other networking environments such as the Internet,
wired LANs, and the public switched telephone
network.
Subnetwork Control Units (SCUs)
Subnetwork Control Units (SCU) are used to extend
the range, or circumvent line-of-sight limitations. The
SCU allows the network administrator to create an
additional cell that manages its associated Remote
Units (RUs) through channel assignment, frame
synchronization, frequency synchronization, packet
assembly and packet routing. In essence, the SCU
creates semi-autonomous
cells within a single Safari
Network under full control of the NCU.
