Site Switching; Preferred Site Selection - Motorola MTX150 User Manual

(received signal strength indication) to
determine if it should switch to another site.
This is transparent to the user. In addition,
the zone controller continuously transmits
adjacent site information to each radio so
that at any time, the radio is able to quickly
switch to the site that has the next highest
RSSI rating.
• Preferred Site - Sites can be programmed
into Privacy Plus Roaming radios to be
preferred, most-preferred, or
least-preferred. This gives the user the
flexibility to keep a radio on a particular site,
regardless of the presence of a stronger
signal from an adjacent site. This also
forces the radio to always look for its
preferred site and use it whenever possible.
• Site Trunking - If the zone controller loses
communication with any site, that site will
revert to what is known as "site trunking."
Under this type of operation, radios are still
able to operate in the trunking mode, but
trunking operations are limited to the site
only.

Plus Roaming radio can be programmed by
your authorized Motorola dealer to
automatically migrate to the lowest failsoft
frequency programmed in its list of 32
control modes. The radio will periodically
scan the control mode to check for the
presence of a valid control mode (in case
the radio roamed into a site that is
trunking).

SITE SWITCHING

Privacy Plus Roaming site switching mainly
uses signal strength to determine whether or
not to switch sites. The radio's preferred site
selection can also determine this. Because the
radio knows the site ID, active control mode,
and the signal strengths of its adjacent sites,
the radio is capable of quickly switching sites.

Preferred Site Selection

Privacy Plus Roaming radios can have up to
eight sites that are individually set as either
always-preferred, most-preferred, or
least- preferred. The default value is no
preference. This feature is programmable by
your authorized Motorola dealer.
