R-168MRAE subscriber multichannel radio station

R-168MRAE
The R-168-MRAE radio station is intended for construction of the high-speed radio networks and batch communications for the TCL (tactical command link). It uses the principle of time division of reception, transmission, data compression and provision with radio access.

Components parts:
unit PRD, unit UM, directional antenna R, antenna B, antenna , mounting set, unit R-168-UVRD-, SPTA-S set, in-line documentation set.
Advisable basic delivery set: unit PRD, unit UM, antenna B, SPTA-S set, in-line documentation set.
Types of operation: mating with microphone-telephone handset and DTE, transmission and reception of ordering, digital and voice data, mating with data sources via the S1-FL, S1-TCh, RS-232, Ethernet 10\100 interfaces, antinoise coding of data transmitted, adaptive retuning to spare frequency, cryptographic protection of data, automatic check for serviceability.
Operation modes: batch communications, remote control via interface RS-232, input, output and urgent erasure of radio data, point-dots without use of central station, automatic retransmission.

Particularities of the radio station:
ciphering with 2256 combinations excludes unauthorized overhearing;
interfaces: I port, S1-Ch, S1-FL (up t 16 bps), 10/100 s Ethernet, RS-22, (up to 115 kbps);
support of rotocols: /I, , F, F;
data rate: without ciphering 3.5 bps; with ciphering 1.75 bps;
effective radio interference control at the expense of doubling of data on the different radio channels and possibility of retuning of the second radio channel in the frequency non-affected with interference;
use of directional antennas in the both channels simultaneously;
batch communication, including video and sound;
common channel speed and signals format for all subscription stations
adaptive change of the data rate;
increase of the output transmitter power at the expense of the external PA use;
possibility of retransmission without the loss in data rate;
possibility to double the data rate;
each radio modem is a source for transmission of subscription data.
