Datasheet
uComm Acoustic Modem
Description
The uComm family of acoustic
modems provide simple and easy to
use acoustic communication links for
the wireless transmission of a variety
of subsea data.
uComm products utilise wideband
signal processing which is field
proven to provide unprecedented
levels of robustness and flexibility in
challenging acoustic environments.
The uComm comes out of experience
gained whilst utilising over 35 years
of experience with underwater
acoustic telemetry. The result is an
easy to use, robust and highly
reliable acoustic modem.
The simple serial interface allows the
user to acoustically “pair” two
uComm modems and then use them
as a seamless data link similar to a
serial cable connection.
To ensure minimal interference
uComm provides over 250 unique
addresses as standard.
Adaptive data rate and transmit
power control techniques ensure the
maximum achievable transfer rate is
maintained for all acoustic
environments. The data transfer rate
ranges from 9,000 bps down to
200 bps depending on the
environment.
Key Features
Advanced communication protocols
and intelligent data packet stitching
ensure that latency is minimised and
that only completely error free data is
delivered.
 Gain, Power and Data rate all
automatic, only setup needed is the
address and serial baud rate.
 Simple to configure and use
 Field proven communication
technology; used within critical
acoustic control systems and has
transferred many Gigabytes of user
data.
 Wideband telemetry provides up to
9,000 bps true user data rate
 Robust performance in noisy and
reverberant environments
 Ruggedized housing and connector
 Configuration software allows
throughput analysis and other
diagnostics to show how the link is
operating
 Re-configurable point to point
operation
 Address and serial baud rate
configurable via a downloadable
Android application using the
supplied Bluetooth interface cable
