Product Description
The content of this manual applies to all frequency ranges of the IPSeries Base Stations, unless
otherwise specified. This manual will note key differences between frequency ranges when
appropriate.
The IPSeries Base Stations are intelligent devices designed for stringent requirements of mobile data
communication systems. Intended for mounting in rack units, the base station requires very little room at
tower sites and may be connected via Serial Line Internet Protocol (SLIP) or Ethernet ports. The base
station circuit boards are built using surface mount technology (SMT) and through-hole components. At
the minimum, the unit requires a 13.8 VDC power supply, an antenna system, and a high-speed data
connection to an Internet Protocol Network Controller (IPNC) system to operate. The base station is
typically teamed up with a Power Amplifier (PA) and third-party system components such as antennas,
preamplifiers, preselectors, filters, and combiners.

Product Functionality
The base station utilizes an internal high-performance 4-level Frequency-Shift Keying (FSK) wireless data
modem (19200 bps or 32000 bps) for 25 kHz channel spacing, a multi-layered approach to signaling
reliability, including patented multi-receiver Intelligent Diversity Reception, dynamic scrambling, data
interleaving for burst error protection, Forward Error Correction (FEC), and Viterbi soft-decision
algorithms.
The IPSeries Base Station technology includes IPMobileNet’s Diversity Reception (DR) capability.
Diversity Reception reduces the number of fades and the effects of multi-path reception. With the use of
three (3) antennas, mounted as far apart as possible on the base station tower, the Diversity Reception
System (DRS) minimizes the effects of fading. One of the antennas is likely to receive a viable signal
while the others may not. DRS minimizes fading effects by comparing the signal levels from the three (3)
antennas, and selecting the strongest signal.
Diversity is most effective when the vehicle using an IPSeries Mobile Radio is in motion.

External Features
The base station technology is enclosed in a sturdy aluminum case. The external features consist of a
series of connectors in the rear of the base station and light emitting diodes in the front of the base
station, as described in this section.
aThe product warranty becomes void if an uncertified or unauthorized individual removes the base
station cover.
