Additional Performance Enhancement
The following performance enhancements are some of the latest creations designed to enhance the
security, quality, and efficiency of the radios.
ASTRO 25 Enhanced Data
ASTRO 25 Enhanced Data is optimized to handle different message sizes and variable update rates
from different applications of the radio. Add Enhanced Data to the Integrated Data system with a
software installation to improve data channel efficiency and enable denser network traffic.
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 such as 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 scenarios from happening, especially when a wideband antenna is
used. This feature allows the adjustment of the internal SSI clock rate of the radio. This subsequently
reduces the possibility 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
SecureNet allows user to perform secured communications on an Analog or Motorola Data
Communication (MDC) channel. The MDC Over-the-Air Rekeying (OTAR) feature will allow users to
perform OTAR activities on an MDC channel.
Over-the-Air Rekeying
The Over-the-Air Rekeying (OTAR) feature allows the dispatcher to remotely reprogram encryption
keys in the radio after a rekey request.
Single-system OTAR
Single-system OTAR allows a radio to be rekeyed by only one Key Management Facility (KMF) or
Key Management Controller (KMC).
Multi-system OTAR
Multi-system OTAR allows a radio to be rekeyed by multiple KMFs. After an initial programming, the
radio is able to seamlessly move to different secure systems associated to a newly selected
channel.
NOTICE: This feature must be preprogrammed by a qualified radio technician. Check with
your dealer or system administrator for more information.
P25 Digital Vehicular Repeater System (DVRS)
Motorola Solutions offers an MSI Certified APX compatible, third Party, P25 Digital Vehicular Repeater
System (DVRS) that provides low-cost portable radio coverage in areas where only mobile radio
coverage is available and portable radio coverage is either intermittent or non-existent.
