CHAPTER 3: PRODUCT SETUP AND PRELIMINARY TESTING Base Station Setup Intended for rack unit configuration, the base station can be installed in an existing rack or assembled into a rack of its own. Rack Unit Mounting Figure 7: Base Station Mounting in the Rack Unit (Front View) Table 5 lists the required components for a base station setup.
CHAPTER 3: PRODUCT SETUP AND PRELIMINARY TESTING Preliminary Testing This section provides a functional preliminary test for the base station prior to installation. It is used to determine the condition of the new base station before placing into service. If the base station is found to be non-functional after completing this test, refer to Chapter 6: Customer Support for the appropriate action. ! This section applies to all base station frequency ranges.
CHAPTER 3: PRODUCT SETUP AND PRELIMINARY TESTING Preliminary Test Procedure Perform the following initial setup to prepare the base station for preliminary test: Step 1 Connect the base station to the 13.8 VDC power supply. Step 2 Power on the base station and verify that the LED’s illuminate and the power LED on the front panel remains illuminated. Step 3 Verify that the base station DC-supply current is <1.2 amps.
CHAPTER 4: PRODUCT INSTALLATION Installation Overview This chapter provides the basic setup involved in the installation process of an IPSeries Base Station. For backhaul requirements, refer to Appendix A of this document. 1 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.
CHAPTER 4: PRODUCT INSTALLATION Adjusting the Power The power output of the base station will depend upon whether it will be used to drive an external power amplifier or transmit directly over-the-air. ! In either case it is important to measure and set the transmitter power output using a wattmeter and dummy load before connecting it to the power amplifier or antenna system. The base station power is adjusted mechanically by tuning a potentiometer (pot) on the bottom of the base station.
CHAPTER 4: PRODUCT INSTALLATION Figure 10: Power Adjustment Potentiometer Location for the IP8B Step 1 Connect a computer with the HyperTerminal utility to the base station’s monitor serial port. ! Refer to the section titled HyperTerminal Setup located in Chapter 5: Programming Instructions for HyperTerminal Setup and access instructions. Step 2 Launch the HyperTerminal utility. Step 3 Locate the adjustment hole (see Figures 8, 9, or 10 according to the model being used).
CHAPTER 4: PRODUCT INSTALLATION Step 7 Once the adjustment is made, connect the base station to the external amplifier and connect the wattmeter and dummy load to the amplifier’s output. Step 8 Measure the power output of the amplifier. ! 1 If the amplifier does not produce the expected power, additional adjustments to the base station output are necessary. When making large adjustments in power, the external amplifier should be disconnected from the base station and the base station’s power reset.
CHAPTER 4: PRODUCT INSTALLATION Installation Instructions ! If setting up a new rack unit, make sure to complete the rack unit setup according to the Manufacturers instructions. Interconnection Diagram Figure 11: Interconnection Diagram Base Station Installation into the Rack Unit Receiver and Transmitter Connections To connect the base station, perform the following steps: Step 1 Connect the RF coaxial cable to Receiver 1 (RX1) on the back of the base station.
CHAPTER 4: PRODUCT INSTALLATION Step 7 Connect the RF coaxial cable to the Transmitter (TX) connection on the back of the base station. Step 8 If connecting to a power amplifier (as shown in the figure below), connect the cable from the base station to the power amplifier via the Transmitter (TX) connection. If not connecting to a power amplifier, skip to Step 11. Step 10 If a power amplifier is used, connect an RF coaxial cable to the output port of the power amplifier.
CHAPTER 4: PRODUCT INSTALLATION Single Base Station Configuration Figure 13: Base Station Ethernet Connection To connect a single base station, perform the following steps: Step 1 Plug in the Ethernet crossover cable into the Ethernet port on the base station (as shown in the figure above).
CHAPTER 4: PRODUCT INSTALLATION Typical Antenna Configuration Base station antenna configurations may vary from site to site depending on the type of mounting structure, the presence of existing antennas, mounting structure loading limitations, etc. The following information is provided as a guideline for a typical scenario. Figure 14: Typical Antenna Configuration An otpimal antenna mounting configuration is shown in the figure above.
CHAPTER 4: PRODUCT INSTALLATION Near-Field Exclusion Zone The near-field exclusion zone (NFEZ) is the required distance between antennas 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.
CHAPTER 4: PRODUCT INSTALLATION Power Connection Figure 15: Base Station Power Connection To connect the base station power connector, perform the following steps: Step 1 Connect the power cable to the base station power supply connection (as shown in the figure above). Step 2 Connect the wires to the appropriate output (+ and -) output posts on the power supply (as shown in the figure above). 2003 IPMobileNet, Inc. 26 IPSeries MR User Manual / Rev.

APPENDIX A: BACKHAUL REQUIREMENTS 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.
APPENDIX A: BACKHAUL REQUIREMENTS 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.
