MASQ Predicted Performance*
Preset Bit Rate (bps) Carrier Freq. (Hz) Transmission Bandwidth (Hz)
Range predictions are based on spherical spreading and absorption
models, incorporating surface noise and biological (short transients)
in the shallow water case. These predictions have been validated by
actual measurements made in close to ideal deep water conditions
and very rough shallow water conditions.

*Data rate fi gures quoted are raw data rate (excluding all protocol overheads which are typically 20%). Actual transmission bandwidth
is also dependent on transmission hardware including matching network and transducer. Restrictions to actual bandwidth – e.g. due to
fi ltering - will reduce Signal to Noise Ratio (SNR) and if output power is kept constant, reduce range performance.
