INTRODUCTION

The Dual E1 version of TRACER provides two, individual E1 transports via a 2.4 GHz or 5.8 GHz,

direct sequence, spread spectrum microwave link. The transmitter output power is 20 dBm maximum

while the receiver sensitivity is -89 dBm @ 2.4 GHz and -87 dBm @ 5.8 GHz. System performance is

determined, in part, by the engineering of the microwave link. Each TRACER radio is comprised of two

components – the baseband processor and the radio frequency converter (RFC). The E1 interfaces

(G.703, G.704 compliant) are provided on the back of the baseband processor, which is mountable in a

515 mm rack. The radio frequency converter is rackmountable adjacent to the baseband processor or

mastmountable in a weatherproof enclosure, located up to 110 meters apart, using RG-8 style coax. A

single coaxial cable connects the baseband processor (via a Type N connector) to the RFC and another

coaxial cable connects the RFC to the antenna (via a Type N connector).

Applications

Any application that would typically use metallic E1 as a transport can use the TRACER instead. Figure

1-1 illustrates a typical application.

In addition to telephony applications, TRACER can be used in data communications such as inter-

networking, video conferencing, and telemetry.

Spread Spectrum

Spread spectrum is a form of communication in which the bandwidth of a message signal is intentionally

increased or “spread.” There are two methods of spreading -- frequency hopping and direct sequence.

TRACER employs direct sequence spread spectrum.
