8.9 Site Roaming
8.9 Site Roaming
Site Roaming is the function to migrate automatically to the site (channel) providing better radio environment if a
transceiver is operated in the NXDN Conventional system.
The transceiver receives a synchronization signal transmitted from the repeaters in multiple sites at regular time intervals,
and detects the RSSI level. Therefore, the transceiver migrates automatically to the channel providing better radio
environment.

This function can be used by configuring channels for each zone in Site Roaming or Site Roaming with RAN (a maximum
of 16 channels for each) by using KPG-169D/ KPG-170D/ KPG-175D.
Site Roaming Behaviors
If the zone configured as Site Roaming or Site Roaming with RAN is selected, the transceiver automatically initiates Site
Roaming on the channels configured for the zone.
For Portable, the LED blinks green upon the initiation of Site Roaming.
For Mobile, "ro" appears on the LED display upon the initiation of Site Roaming.
When the transceiver transmits, the RAN code configured for Revert Channel is multiplexed on a signal.
The channel the transceiver received last time is retained even if the transceiver is turned OFF. When the transceiver is
turned ON and transmits next time, the channel will be used as the Revert Channel. If there is no Revert Channel, the
channel of the lowest number configured for the zone will be used as the Revert Channel. While the transceiver is
receiving, or if the transceiver transmits while the length of time configured for Dropout Delay Time or Dwell Time is
elapsing, the transceiver transmits using the Revert Channel.
