In the UDP mode, the transceiver supports point-to-multipoint
serial-port to serial-port connectivity. In the TCP mode, it supports
point-to-point Ethernet/IP to serial port connectivity.
For further details on the transceiver’s Serial Gateway interface modes,

1.2.7 High-Speed Mobile Data
The iNET radios support high-speed data communications in a mobile
environment. Remote radios roam between different access points, pro-
viding seamless transitions and continuous coverage. For additional
information on configuring a mobile network, refer to

1.3.1 Extending Network Coverage with Repeaters
What is a Repeater System?
A repeater works by re-transmitting data from outlying remote sites to
the Access Point and vice-versa. It introduces some additional
end-to-end transmission delay but provides longer-range connectivity.
In some geographical areas, obstacles can make communications diffi-
cult. These obstacles are commonly large buildings, hills, or dense
foliage. These obstacles can often be overcome with a repeater station.
Option 1—Using two transceivers to form a repeater station
(back-to-back repeater)
Although the range between transceivers can be up to 40 km (25 miles)
over favorable terrain, it is possible to extend the range considerably by
connecting two units together at one site in a “back-to-back” fashion to
form a repeater, as shown in
Figure 1-7
. This arrangement should be
used whenever the objective is to utilize the maximum range between
stations. In this case, using high-gain Yagi antennas at each location will
provide more reliable communications than their counterparts—omni-
directional antennas.
