12 CONVENTIONAL IP NETWORK / 12.2 Site Roaming
Note
・ From among the repeaters interconnected by using an IP network, configure one repeater as Primary and one repeater as
Secondary respectively.
To use this function, Beacon needs to be enabled, and the configurations related to Site Roaming need to be configured even
・
on the subscriber units.
Configure Common Multicast IP Address only when "Multicast" is configured in IP Casting.
・
To synchronize the timing to transmit a beacon, the configuration value in Transmit Interval Time needs to be the same for
・
each repeater, and the configuration value in Duration needs to be the same for each repeater.

Duration
Duration is the length of time for which the interconnected repeaters by using an IP network continue to transmit a
beacon.
The repeater must transmit a beacon until the subscriber unit determines the site providing good radio environment
using the received beacon. If the number of repeaters interconnected by using an IP network increases, the length of
time for the subscriber unit to determine the site providing good radio environment increases; hence a long duration
needs to be configured for Duration.
Note
To use this function, Beacon needs to be enabled, and the configurations related to Site Roaming need to be

configured even on the subscriber units.

Transmit Interval Time
Transmit Interval Time is the interval time in which the interconnected repeaters by using an IP network transmit a
beacon.
The frequency, which the subscriber unit determines the site providing better radio environment and then automatically
migrates to the site (channel), can be controlled by using the configuration for Transmit Interval Time. For instance, if
the subscriber unit moves at a high speed, the subscriber unit frequently moves to accessible area of each site; hence
the site providing good radio environment frequently changes. In this case, configuring a short duration for Transmit
Interval Time enables the subscriber unit to determine the site providing better radio environment at short intervals. On
the contrary, if the subscriber unit hardly moves from the accessible area of the same site, the subscriber unit does not
need to determine the site providing better radio environment at short intervals; hence a long duration can be
configured for Transmit Interval Time.
