Additional Performance Enhancement

The following are some of the latest creations designed to
enhance the security, quality and efficiency of APX mobile

Dynamic System Resilience (DSR)

DSR ensures the radio system is seamlessly switched to a
backup master site dynamically in case of system failure.
DSR also provides additional indication e.g. failure detection,
fault recovery, and redundancy within the system to address to
the user in need. Mechanisms related to the Integrated Voice
and Data (IV & D) or data centric are all supported by DSR.

CrossTalk Prevention

This feature prevents crosstalk scenario from happening,
especially when a wideband antenna is used. This feature
allows the adjustment of the Trident Transmitting SSI clock rate
in the radio to be varied from the Receiving Frequency. This
subsequently reduced the possibilities of radio frequency
interfering spurs and prevents the issues of crosstalk.

Encrypted Integrated Data (EID)

EID provides security encryption and authentication of IV & D
data bearer service communication between the radio and the
Customer Enterprise Network.


SecureNet allows user to perform secured communications on
an Analog or Motorola Data Communication (MDC) channel.
The MDC OTAR feature will allow users to perform OTAR
activities on an MDC channel.
