P25 Digital Vehicular Repeater System
Motorola Solutions offers an MSI Certified APX compatible, third party, P25 Digital Vehicular Repeater
System (DVRS). This provides low-cost portable radio coverage in areas where only mobile radio
coverage is available.
The system sends DVRS firmware and configuration updates over-the-air. The following scenarios
occur during the update:
•
If the update is accepted, the display shows Updating DVRS.
•
If the update fails, the display shows DVRS updt failed. For more information, contact your
system administrator.
NOTE: Portable subscriber units enabled in the system for Radio Authentication shall be able to
authenticate regardless of whether they are communicating directly on the system or by using a
DVRS.
DVRS can also work with SmartConnect to use broadband coverage for the in-vehicle mobile. Portable
radios communicate through the in-vehicle mobile to the system through the LTE, Satellite, or Wi-Fi
connection. This extends the system coverage when you are away from the vehicle.

Conventional Talkgroup and Radio Scan Enhancements
Enhancements have been made to the Conventional Talkgroup at the system to improve the Scan
feature operation significantly when multiple agencies are using a single conventional radio frequency

that are relevant to the users rather than all talkgroups on the channel.
The enhancements support the following Scan mode:
•
Mixed Vote Scan.
•
Standard Conventional Scan.
•
Priority Operation.
