Product Description

The M64450G25 Mobile Radio works within a frequency range of 450-506 MHz and requires a 1/4-wavelength
antenna.
The IPSeries High Speed Mobile Radios are intelligent devices designed for the challenging requirements
of mobile data applications. Mounted in vehicles, other intelligent devices may connect to the serial or
Ethernet ports for connectivity back to the Internet Protocol Network Controller (IPNC) and other such
servers. It provides the mobile link to land-based wired networks.

Product Functionality
The IPSeries High Speed Mobile Radio utilizes a high-performance, 4-level Frequency-Shift Keying (FSK)
wireless data modem for 32 kbps operation, 16-level FSK for 64 kbps in 25 kHz channels; a multi-layered
approach to signal reliability. It features low power consumption, high performance integrated GPS
receiver. Embedding this technology in the mobile radio lowers the cost of acquiring GPS data from
vehicles and ensures optimal performance.
The mobile radio technology includes Diversity Reception (DR) capability. DR reduces the effects of
fades in a multi-path environment. With the use of two (2) antennae mounted at a calculated distance on
the roof of the vehicle the Diversity Reception System (DRS) minimizes the effects of fading by
intelligently selecting the receiver with a better signal.

Diversity is most effective when the vehicle is in motion.
