CHAPTER 1: INTRODUCTION
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 when appropriate.
The IPSeries Base Stations are intelligent devices designed for the 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 to via Serial Line Internet Protocol (SLIP) ports or Ethernet. 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, antenna system, and 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.
Figure 1: IPSeries Base Station External Illustration (Front View)
Product Functionality
The base station utilizes an internal high-performance 4-level Frequency-Shift Keying (FSK) wireless data
modem (19200 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.

Block Diagram Definitions
For increased data security, the modem supports the U.S. Government developed Digital Encryption
!
Standard (DES) data encryption and decryption protocols. This capability requires installation of thirdparty Internet Protocol (IP) compliant DES encryption and decryption software.
The standard IPSeries Base Station circuit board contains five (5) main sections defined below:
Input/Output Circuitry associated with one of the following base station’s data
connectors:
q RS232 Serial Port DB9 Data Connector
q RJ45 Ethernet 10 Base T Interface Connection
! For further details on the Ethernet Controller refer to the Crystal
LAN Ethernet Controller Product Bulletin (CS8900AEthernetCtrlr.pdf) available on the Product Documentation CD.
System Controller Houses the modem, diversity, and Ethernet circuitry. Manages the
operation of the base station’s modem providing transmit timeout
protection in the event a fault causes the base station to become halted
in the transmit mode. The system controller also handles the loading of
selected transmit and receive frequencies into the injection synthesizer.
Includes memory for storage through Electrically Erasable
Programmable Read Only Memory (EEPROM) of the base station’s

CHAPTER 1: INTRODUCTION
operating parameters, which are retained after the base station’s power
is cycled off.
Modems Convert data into an analog audio waveform for transmission and analog
audio from the receiver to serial data interface. There is one (1) modem
that is dedicated to the transmit operation and two (2) modems dedicated
to the receive operation. The modem dedicated to the transmit supports
a 115.2 KBPS data transmission rate on the serial port, SLIP protocol,
and a 19.2 KBPS OR 9.6 KBPS over-the-air data transmission rate.
Provides Forward Error Correction (FEC) and Error Detection (using
Cyclic Redundancy Check or CRC), bit interleaving for more robust data
communications, and third generation collision detection and correction
capabilities.
Diversity Reception Circuitry selects one of three (3) diversity receiver audio outputs for
processing by the modem by comparing the Received Signal Strength
Indication (RSSI) output from each receiver. Audio from the receiver
with the highest RSSI value is passed to the modems.
RX Injection The Injection Synthesizer board provides a highly stable local oscillator
signal for the three (3) receivers. This displays a serial data input/output
interface, synthesizer, and VCO.
Transmitter Consists of an exciter and a power amplifier module covering various
frequency bands in segments. The transmitter power control is included
with the power supply circuitry on the same board.
Receiver 1/Receiver 2/ Uses three (3) discrete receivers tuned to the same frequency.
Receiver 3 The three (3) receivers are required to support IPMobileNet’s base
station Diversity Reception System (DRS).
NOTE: Some installations use only two (2) receivers.
The receivers are double-conversion superhetrodynes with an
Intermediate Frequency (IF) of 45 MHz. Each receiver consists of
bandpass filters, RF amplifiers, a mixer, 45 MHz crystal filter, and a one-
chip IF system. The injection synthesizer provides the first local
oscillator signal and outputs from each receiver include RSSI and analog
audio for Diversity Reception.
Power Supply Power supply circuitry derives the various operating voltages required by
the base station. Fixed voltage regulators are employed through the
base station for this purpose.
