FEATURES PLANNED FOR DEVELOPMENT
 Additional modem support, where S4285 is currently under development.
 Integration of Listen Before Transmit (LBT) technology.
 Data Link Protocol layer Broadcast mode support in addition to ASYNC and SYNC modes.
 Data Port streaming of unknown data for transmit with minimal buffering where
transmitting of the preamble and known data will begin immediately vs. requiring to
buffer all the data prior to transmitting the data.
 Graphical Constellation and Channel Impulse Response (CIR) displays for both analysis of
the radio equipment used to transmit and receive the waveforms and ongoing HF channel
state analysis of multipath, fading and other conditions affecting the channel.
 Test Waveform (2400bps) to characterize signal path between modem/radio pairs to
determine SNR, available bandwidth, radio ALC and AGC effects and distortion from
non-linear effects with CIR display of I and Q data and other parametric information.
 Full Sync on Data (SoD) supporting late entry and recovery where the known data bits
are used for synchronization.
