SOLO4 – Audio and Telemetry Transmitter

The SOLO4 Audio and Telemetry

Transmitter from Cobham Surveillance

is a COFDM transmitter, designed

specifically for the transmission of

audio and telemetry data. The SOLO4

Audio and Telemetry Transmitter has

domo technology at its core and can be

configured into different user selectable

bandwidths, to satisfy a variety of

requirements. Bandwidths from 25KHz to

125KHz are available offering user capacity

from 14 to 146kb/s. This capacity can be

shared between audio and user RS232

telemetry data, in any combination. Wider

bandwidths are available on request.

The SOLO4 Audio and Telemetry

Transmitter employs a unique narrow

band COFDM modulation and will transmit

telemetry data and audio in a non-line of

sight environment up to 5km, depending

on mode and frequency. The SOLO4 Audio

and Telemetry Transmitter is typically

employed to provide talk back and also

telemetry data for PTZ control in Cobham

wireless video systems, especially mobile

systems.

Security is ensured with AES128/256 bit

encryption subject to export controls.

The SOLO4 Audio and Telemetry

Transmitter can also be connected to

Cobham IP solutions to create rugged

wireless IP Bridge applications.

Supplied in a rugged, lightweight weather

proof aluminium chassis, the SOLO4 Audio

and Telemetry Transmitter can be used

in body-worn applications, or prolonged

outdoor deployments.
