Tait provided the DoD with a P25 digital system. Tait P25 TB9100 base stations were
installed at three sites – one at Alice Springs and two others in the surrounding
area. Tait P25 TM9155 mobiles and TP9160 portables were deployed to maintenance
personnel and vehicles. A spare Tait P25 TB9100 base station was provided to
enable quick response to any maintenance issues.

The Tait P25 digital system significantly improved coverage between the facilities,
without the need for any additional sites or channels. The Tait P25 TB9100
base station’s Ethernet interface allowed the three repeater sites to be linked
via voice over IP (VoIP). This created the wider area network required to cover
the 11,583 square miles (30,000 square kilometers) of land.

To strengthen communication clarity, base and mobile voting were implemented.
This feature, with the system’s ability to recover audio, means the new system
provides superior audio quality across the coverage area.

Tait improved worker safety through the emergency call button on each Tait P25
TM9155 mobile and TP9160 portable radio. When pushed, the user is directly linked
to headquarters allowing for improved response times. Every P25 transmission is
made over the P25 Common Air Interface (P25 CAI) which can only be heard by a
P25 digital radio. For BAE staff this ensures that those operating analog radios in the
surrounding area cannot access their communications. Furthermore DoD also has
access to P25 digital encryption options which could be used in the future to protect
highly sensitive information.

Talk groups, a standard P25 conventional feature, have been implemented to
improve internal security measures and further streamline communications.
By grouping users into talk groups, the DoD has greater control over who listens to
what, which helps streamline communications by ensuring others on the network are
not disturbed by irrelevant chatter.
