2003 IPMobileNet, Inc. 7 IPSeries MR User Manual / Rev. A / 08-Apr-03
Product Description
The content of this manual applies to all frequency ranges of the IPSeries Mobile Radio, unless
otherwise specified. This manual will note key differences when appropriate.
The IPSeries Mobile Radios are intelligent devices designed for the challenging requirements of mobile
data and voice 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. The IPSeries Mobile Radio provides the mobile link to land-based wired networks. The mobile
radio circuit boards are built using surface mount technology (SMT) and through-hole components.

Product Functionality
The mobile radio utilizes a high-performance, 4-level Frequency-Shift Keying (FSK) wireless data modem;
a multi-layered approach to signal reliability, including patented multi-receiver Intelligent Diversity
Reception; data scrambling; data interleaving; Forward Error Correction (FEC); and Viterbi soft-decision
algorithms, providing up to 20 dB improvement in Signal-to-Noise Ratio (SNR) in low signal-to-noise
environments. This assures a very high message success rate even while transferring large blocks of
data at high vehicle speeds. The mobile radio features a 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 IPSeries Mobile Radio technology includes IPMobileNet’s Diversity Reception (DR) capability. DR
reduces the effects of fades in multi-path environment. With the use of two (2) antennas mounted at a
calculated distance on the roof of the vehicle (refer to the section in Chapter 4 titled Antenna
Configuration) 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.
