Switch – to – radio communication using Packet Data
This is the recommended scenario wherever it is possible. It requires an IP connection
between the master application / SCADA server and the TETRA infrastructure.
The Piciorgros TGW-100 is interfacing the serial communication from the SCADA
master for the connection to the TETRA network, offering the same functionality like
protocol analysis and routing, data compression etc. as the TMO-100; but instead of
using the TETRA air interface it'll use a fast IP connection to the packet data gateway of
the TETRA infrastructure.
As no air interface communication is needed on the master side this solution will allow
serving a nearly unlimited number of modems in the field, just depending of the number
of base stations and the distribution of modems to them.
In comparison to the radio-to-radio scenario the data speed is doubled and the latency
divided by two in the switch-to-radio solution.
As the packet data gateway of the infrastructure is needed which allows the passing of
any IP packets, this solution will work out of the box on any TETRA infrastructure
which support packet data and the connection of an external IP source using the packet
data gateway as a router to the TETRA network.
