4 Introduction

The domo SOLO4 and SOLO2 product range enables the user to build

wireless digital microwave video systems. The domo SOLO4 and

SOLO2 products have been designed to provide rugged point-to-point

links for high quality full frame rate video, and audio, even in non line of

sight and urban environments.

Existing analogue systems suffer from impairments such as video noise,

loss of colour information and poo

r image quality when line of sight

cannot be maintained, and solutions based on wireless internet

standards and PC platforms deliver poor quality video.

The domo SOLO4 and SOLO2 system is a digital system that uses the

COFDM modulation technique, which effectively eliminates the

problems caused by multipath and reflections.

The SOLO product range allows law enforcement, surveillance and

emergency service

communities to now receive the highest quality

video images, in real time, direct from personnel, buildings and vehicles.

The domo SOLO2 system employs the DVB-T 2K carrier COFDM

technology.

The domo SOLO4 system employs a revolutionary narrow band

2.5MHz COFDM technology which demonstrates better propagation for

longer range links, and extra bandwidth efficiency. The domo SOLO4

system can also be upgr

aded to include a 1.25MHz COFDM modulation

and MPEG4 compression for excellent range performance.

The domo SOLO4 and SOLO2 systems employ common transmitter

and receiver hardware.

• The SOLO4 and SOLO2 transmitter is a lightweight, low-power

transmitter suitable for body-worn applications where size, weight and

power consumption are at a premium.

• For longer range applications such as vehicle transmissions, the

SOLO4 or SOLO2 transmitter can be upgraded with the use of a

booster amplifier.

• The SOLO4 and SOLO2 receivers are diversity input receivers with

extensive built in spectrum analysis tools. The receivers can be fitted

with an optional NETSTREAM card, which then gives the option of

streaming the received video onwards over IP networks.

IMPORTANT NOTE

The SOLO4 and SOLO2 product range has been specifically designed for government

security and law enforcement users, the equipment will tune across frequencies that are

only available to licensed government users. Non-government users should employ the

equipment restricted to the license exempt bands only typically 1.389 to 1.399GHz, 2.400

to 2.483GHz and 5.725 to 5.875GHz
