Optimization Manual: Scope and Layout 1 Scope of This Document This document provides information pertaining to the optimization and audit tests of Motorola SC 4812T Base Transceiver Subsystem (BTS) equipment frames equipped with trunked high–power Linear Power Amplifiers (LPAs) and their associated internal and external interfaces.
PAGE 30
1 Optimization Manual: Scope and Layout – continued Document Composition This document covers the following major areas. Introduction, consisting of preliminary background information (such as component and subassembly locations and frame layouts) to be considered by the Cellular Field Engineer (CFE) before optimization or tests are performed.
PAGE 31
Optimization Manual: Scope and Layout – continued 1 Graphical User Interface Overview The LMF uses a GUI, which works in the following way: Select the device or devices. Select the action to apply to the selected device(s). While action is in progress, a status report window displays the action taking place and other status information. The status report window indicates when the action is complete and displays other pertinent information.
PAGE 32
1 Purpose of the Optimization Why Optimize? Proper optimization and calibration assures: Accurate downlink RF power levels are transmitted from the site. Accurate uplink signal strength determinations are made by the site. What Is Optimization? Optimization compensates for the site-specific cabling and normal equipment variations. Cables that interconnect the BTS and Duplexer assemblies (if used), for example, are cut and installed at the time of the BTS frame installation at the site.
PAGE 33
Purpose of the Optimization – continued 1 These values are factored in by the BTS equipment internally, leaving only site specific antenna feed line loss and antenna gain characteristics to be factored in by the CFE when determining site Effective Radiated Power (ERP) output power requirements. Each C–CCP shelf BBX board is optimized to a specific RX and TX antenna port. (One BBX board acts in a redundant capacity for BBXs 1–12, and is optimized to all antenna ports.
PAGE 34
1 Required Test Equipment Policy The LMF is used in conjunction with Motorola recommended test equipment and is part of a “calibrated test set”. To ensure consistent, reliable, and repeatable optimization test results, only recommended test equipment supported by the LMF must be used to optimize the BTS equipment. NOTE During manual testing, you can, of course, substitute test equipment with other test equipment models not supported by the LMF, but those models must meet the same technical specifications.
