Product Description
The M64700G25 Mobile Radio works within a frequency range of 794-806 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. The high speed mobile radio circuit
boards are built using surface mount technology (SMT) and through-hole components.
Figure 1: IPSeries High Speed Mobile Radio (Front View)
Product Functionality
The high speed mobile radio utilizes a high-performance, 32-level QAM. Further it uses state-of-the-art
OFDM technique. This new technique will enable the high speed mobile radio to transmit and receive
more than 100 Kbps data in a 25 kHz band. The high speed mobile radio 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 high speed 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) antennas 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.
