Data Compression using the LZ77 algorithm
The TGW-100 has data compression capability and all data records received over the
serial interface are compressed before sending as SDS. At the receiving station, the data
is decompressed before moving it out.
Data compression can improve performance when large data blocks are involved, by
reducing the data that is conveyed over the TETRA network, even if additional SDS
blocks are created (in cases where the original data block does not fit within an SDS).
If using the TGW-100 in conjunction with the discontinued TRM-, RTU-, or MDP-
Type Tetra units, (these ones do not have the compression feature) compression can be
disabled.
