SOLO4 – Audio and Telemetry Receiver
The SOLO4 Audio and Telemetry Receiver
from Cobham Surveillance is a diversity
COFDM receiver, designed specifically
for the reception of audio and telemetry
data. The SOLO4 Audio and Telemetry
Receiver 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.
Additional bandwidths will be available in
the future.
The SOLO4 Audio and Telemetry Receiver
employs diversity reception and a unique
narrow band COFDM modulation. It will
receive telemetry data and audio in a
non-line of sight environment up to 5km,
depending on mode and frequency. The
SOLO4 Audio and Telemetry Receiver is
typically employed to provide talk back
and also telemetry data for PTZ control in
Cobham wireless video systems.
Security is ensured with AES128/256 bit
encryption subject to export controls.
Supplied in a rugged, lightweight weather
proof aluminium chassis, the SOLO4 Audio
and Telemetry Receiver can be used in
body-worn applications, or prolonged
outdoor deployments.
