FUNCTION
Base
FleetTrak
TM
ELOS (CSMA
& TDMA)
It is connected by landline to a central
Host. It communicates with both remotes
and repeaters.
Repeater
FleetTrak
TM
ELOS (CSMA
& TDMA)
As a repeater it communicates with base
stations, other repeaters and remote
stations.
Remote
FleetTrak
TM
ELOS (CSMA
& TDMA)
As a remote it communicates with base
stations, repeaters and other remote
stations.
The MRC-565 operating in GMSK has a maximum data rate of 9.6 kbps. Therefore, the choice
between using the MRC-565 or the MRC-565C is a trade-off between performance and data
rates.
For reference, each of the three networks are briefly described below.
Multiple master stations are interconnected into a clustered star configuration as shown below.
The remote stations transmit their data to whichever master station probe is received. Multiple
master stations will significantly improve the performance of the network because of the
additional RF links available to each remote station.
