Packet Data (IP) Communication
Packet data (PD) communication essentially differs from SDS data communication in
that the TETRA infrastructure must support the use of packet data. Data communication
takes place not through the Control Channel (as in the case of SDS data communication)
but through normal traffic channels. Thus an active PD connection over which data is to
be transferred, affects the availability of the voice channels: this must be taken into
account at the time of network planning. Also the TETRA radios are not addressed by
their ISSI but by the IP address which was assigned to them by the TETRA network.
The main advantage of packet-data based communication in Tetra infrastructures is that
it supports protocols using IP data packets.
Any network which allows the connection of IP based equipment to the TETRA switch
can be used for the TGW-100 if packet data based transmission is used to the TMO-100
outstations.
