CHAPTER 1: INTRODUCTION

516.80540.UM-Rev. D 1-Jun-07 Page 6 of 38

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. At the

minimum, the unit requires a 13.8 VDC power supply, an RF Filter 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 antennae,

preamplifiers, preselectors, filters, and combiners.

Figure 1: Base Station External Illustration (Front View)

Product Functionality

The base station utilizes a high-performance DSP to modulate/demodulate 4 to 16-level Frequency-Shift

Keying (FSK) modem for 25 and 50 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 High Speed 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) antennae, mounted as far apart as possible on the base station tower, the Diversity

Reception System (DRS) minimizes the effects of fading. One of the antennae 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) antennae, and selecting the strongest signal.

 Diversity is most effective when the vehicle using an IPSeries Mobile Radio is in motion.

CHAPTER 4: PRODUCT INSTALLATION

516.80540.UM-Rev. D 1-Jun-07 Page 15 of 38

Installation Overview

This chapter provides the basic setup involved in the installation process of an IPSeries High Speed Base

Station. For backhaul requirements, refer to Appendix A of this document.

S Standard considerations such as air flow clearance above the base station for heat dissipation

and ensuring adequate space exists behind the base station for the routing of cables are of

primary importance.

A minimum clearance of 1 rack space is recommended for natural convection cooling. Coax,

power, and interface cabling service lengths with neat routing will make the removal and

replacement of the base station easier for functional testing and maintenance purposes.

To prevent injury and damage to the base station, exercise extreme caution throughout the

installation process and follow the reminders listed below.

 Follow safety precautions for handling rack unit installations.

 Do not alter the components listed in the Installation Requirements section, unless

substituions are noted within this chapter.

CHAPTER 4: PRODUCT INSTALLATION

516.80540.UM-Rev. D 1-Jun-07 Page 20 of 38

Typical Antenna Configuration

Base station antenna configurations may vary from site to site depending on the type of mounting

structure, the presence of existing antennae, mounting structure loading limitations, etc. The following

information is provided as a guideline for a typical scenario.

Figure 10: Typical Antenna Configuration

An optimal antenna mounting configuration is shown in the figure above. The transmit antenna and

receive antennae are located at different elevations. This vertical separation provides the greatest

degree of isolation between transmit and receive antennae. The three (3) receive antennae are mounted

at the same elevation and are oriented in a 120 degree triangular pattern. A triangular orientation of the

receive antennae provides optimal diversity performance in an omnidirectional pattern.

 The greater the separation between receive antennae, the greater the diversity gain; therefore,

the distance between antennae should be made as great as is practical.

In the event only two (2) receive antennae are used (i.e. a dual receiver diversity reception system), the

receive antennae should be mounted in a broadside orientation with respect to the radio coverage area.

 To prevent the antenna’s radiation pattern from becoming distorted, the immediate area

surrounding each antenna should be kept free from conductive objects (i.e. other antennae, guy

wires, or the tower structure itself). The amount of clear area required to prevent pattern distorion

is equal to the antenna’s near-field exclusion.

CHAPTER 4: PRODUCT INSTALLATION

516.80540.UM-Rev. D 1-Jun-07 Page 21 of 38

Near-Field Exclusion Zone

The near-field exclusion zone (NFEZ) is the required distance between antennae to any other surfaces to

improve transmit and receive performance. The large radio frequency field that builts up around the

antenna upon transmitting is essential for proper data transmission. It can be severely corrupted by metal

objects in the NFEZ. As seen in the previous figure, the transmitting antenna is placed at the very top of

the tower especially if the base station will be required to transmit in all directions (omni-directional).

 If the transmitting antenna cannot be positioned on the top of the tower and must be placed on

a tower arm, then it is important to realize that coverage will be shaded in the area behind the

tower from the anetnna. The installer must be certain that the area of desired coverage is

away from the tower and not behind it.

Receiving and transmitting antennae should not be on the same plane, especially VHF and

UHF systems where the frequency splits are relatiely small. An antenna in the near-field

exclusion zone that is tuned for the same frequency as the transmitting antenna will reradiate

the signal and create unwanted effects on the transmittal signal. The receivers will be

inundated by high levels of radio frequency energy from the transmitting antenna. This is

why it is important to include vertical separation in the plan for the base station installation.

The isolation provided by 30 feet of vertical spearation can dramatically improve the

performance of the base station.

An antenna’s NFEZ can be calculated as follows:

D = 2d2

Where: D is the distance to the anenna’s near field boundary

d is the antenna’s longest linear dimension (in the same units as D)

λ is the wavelength (in the same units as D)

Maximizing the distance between the receive antennae will provide maximum diversity gain and

will minimize antenna radiation pattern distortion.

APPENDIX A: BACKHAUL REQUIREMENTS

516.80540.UM-Rev. D 1-Jun-07 Page 28 of 38

Backhaul Systems

Considering the backhaul system between the base station location and the Internet Protocol Network

Controller location is one of the most critical elements of data transmission. Once data has been

received at the base station, it must be relayed to the IPNC at the user's location quickly, accurately, and

reliably.

Industry standard backhauls are appropriate for IPMobileNet data transmission as long as data is

transmitted cleanly and dependably. Depending upon conditions and accessibility, the preferred method

of data transmission to the remote site is through a wired backhaul.

Wired Backhaul

The Ethernet backhaul is preferred as it uses a T1 (or fractional T1) line or equivalent, which handles

larger volumes of digital data. If the backhaul will be via SLIP connection, then four (4) wire DDS

telephone lines capable of 56 kbps is recommended.

 Do not order a 64 kbps line as it is incompatible with IPMobileNet’s equipment data transmission

speed.

One disadvantage of using wired lines is that the system is under the control of an outside

agency and telephone line faults or system outages impose potential loss of radio communication

through the site affected.

Microwave Transmission Link

Using a microwave transmission link is another option, which is often used when wire cannot be brought

into remote locations. Data transmission is generally very reliable, but adverse conditions can degrade

the quality of the data. High winds, ice on the microwave dish, and other environmental variables can

cause problems and prevent data or voice from completing transmitting.

Newest Backhaul

The 802.11 range of products for wireless data transmission. Several models of 802.11 have been used

successfully.

 Be aware of the possibility of interference on the 2.4 GHz frequency range. The 802.11 product

should only be used for short hops with clear line-of-sight in an environment where minimal radio

interference will exist.

APPENDIX A: BACKHAUL REQUIREMENTS

516.80540.UM-Rev. D 1-Jun-07 Page 29 of 38

Serial Backhaul Capacity

The backhaul with the fastest speed that can provide clean, reliable, and dependable transmission should

be considered when dealing with backhaul capacity. IPMobileNet’s base stations operate at four (4) data

transmission rates, which include the following:

 115,200 bps

 57,600 bps

 38,400 bps

 19,200 bps

The optimal goal is to select a backhaul data rate that remains ahead of the base station’s data

transmittal. For example:

BASE STATION BACKHAUL RESULTS

19,200 bps or

32,000 bps

Anything less than

38,400 bps

Backhaul does not have the opportunity to remain

ahead of the base station’s transmittals if data

packets are dropped or need to be rebroadcast from

the IPNC to the base station.

19,200 bps or

32,000 bps

Anything higher than

38,400 bps

System will be more efficient and always operate at

the base station’s peak performance never waiting for

data to arrive from the IPNC.

64,000 bps 57,600 bps

Backhaul does not have the opportunity to remain

ahead of the base station’s transmittals if data

packets are dropped or need to be rebroadcast from

the IPNC to the base station.

64,000 bps 128,000 bps

Ideal rate and system will be more efficient requiring

less time and operating at the base station’s optimal

performance never waiting for data to arrive from the

IPNC.

128,000 bps 256,000 bps

Ideal rate and system will be more efficient requiring

less time and operating at the base station’s optimal

performance never waiting for data to arrive from the

IPNC.

The 56 kbps DDS line is typically used to create the 57,600 bps asynchronous data line for the serial line

Internet protocol (SLIP) connection between the Internet Protocol Network Controller location and the

base station site.
