operation in power network, even with no voltage in the network;
"last mile" problem solution for any systems;
high interference resistance;
confidentiality of data transmission;
applying noise–shaped signals and special processing algorithms.

"SHOPOT" is a two–way data comminucation channel. It uses the existing infrastructure for dispatcher, monitoring and control systems based on the principle "request–response". The channel is built on the principle "Point–multipoint" with the help of communicators SM–16 (half-duplex modem of data recieve–transmitting via dedicated lines and power network 0,4kV/50Hz or 0,4kV/60Hz) and SMR–16 (half-duplex modem of data recieve–transmitting via a radio channel 432–435MHz).

The channel can be created by free combination of communicators SM–16 and SMR–16 by way of their direct connection with each other via RS485 (RS232) interface. The channel "SHOPOT" provides communication between devices of any system without intermediate transformation of protocols and additional modules, being "transparent" for the system.

The soft and hardware of "Shopot" allows the creation of a temporary access division into the channel (parallel operation) for different systems including:

automatic process control systems, dispatcher systems, automatization of processes and control of life–support subsystems (boiler–room, waterchannel, air–conditioning, ventilation, power supply);
Automated Meter Reading (AMR) systems of energy supply control for residential customers that controls and accounts the consumption of power, heating, hot and cold water, gas;
systems of burglar, fire and perimeter alarm.

The main advantages of channel:

using of already existing infrastructure (power network, radio channel, telephone lines);
solution of "last mile" problems for any systems;
parallel operation of up to 4 different systems in one channel;
confidentiality of data communication;
high interference resistance thanks to noise–shaped signal and special processing algorithms;
programmable access password to the channel.
length of transmitted data package up to 256 byte.
