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 prior to placing into service. If the base station is nonfunctional after completing this test, refer to Chapter 6: Customer Support. 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 antenna to the base station’s TX port. Step 2 Connect the base station to the 13.8 VDC power supply. Step 3 Power on the base station and verify that the LED’s illuminate and the power LED on the front panel remains illuminated. Step 4 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 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.
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. 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. Step 2 Route the cable neatly toward the receive filter.

CHAPTER 4: PRODUCT INSTALLATION Figure 9: Base Station Ethernet Connection To connect a single base station, perform the following steps: Step 1 Plug in the Ethernet cable into the Ethernet port on the base station (as shown in the figure above). Step 2 Route and plug in the other end of the Ethernet cable to an Ethernet switch or router. Step 3 Route and plug in another Ethernet cable from the Ethernet switch or router to the Ethernet port of the Internet Protocol Network Controller (IPNC).
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 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.
CHAPTER 4: PRODUCT INSTALLATION 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.
CHAPTER 4: PRODUCT INSTALLATION Power Connection Figure 11: 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). ©2005 IMobileNet, Inc. 516.80540.UM-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.

GLOSSARY OF TERMS Data Interleaving A technique in which the order of the individual data bits within the data to be transmitted is shifted and interleaved so as to disassociate adjacent data bits in a message. This scheme is complementary to forward error correction (FEC) algorithms. Data Scrambling A technique used to ensure no repeating patterns exist in the transmitted data stream, a method of ensuring the data is reasonable random in nature.
GLOSSARY OF TERMS FSK Frequency Shift Keying – Digital modulation (a form of FM) where the carrier frequency is shifted above and below the operating frequency (in discrete steps) in response to a digital data input. Full Duplex A dual frequency mode of operation in which transmission and reception occur simultaneously.
