WaveNet Link AX Installation and Operations Manual

1.0 General Overview

1.1

WaveNet Link Series Product Family

All Link AX radios are members of the WaveNet Link Series radio product family. The WaveNet
Link Series is designed to provide an economical wireless solution for local access telecommu-
nication requirements.

This manual addresses, in detail, the operation of the Link AX. For detailed information on
other members of the WaveNet Link Series, please refer to the appropriate Operation
Manual(s).

1.2

Introduction to the Link AX

The Link AX is a digital radio designed for use as a point-to-point communications system. The
Link AX is used in the following applications:

Wireless DSL
Point-to-point (building to building)
Internet Service Providers (ISPs)
Local Exchange Carriers (LECs)
Wireless Local Loop (WLL)
Backup Solutions
Temporary Links

The Link AX radio is designed for operation in two of the Unlicensed National Information
Infrastructure (U-NII) bands at frequencies of 5.250 - 5.350 GHz and 5.725 - 5.825 GHz.

Each Link AX is comprised of a pole mounted RF/antenna unit. Each radio  is powered by means
of a DC power supply (optional AC-DC power supply available) which is fed to the unit through
a power/data cable. The system has a total data transmission capacity of 8 Mps full-duplex.
Refer to the Link AX data sheets for detailed information relating to product offerings and
specifications.
