1. The document provides guidance on reconfiguring existing ERICSSON 884 Microcells to support the continued deployment of 3G technology in the San Francisco Bay Area. 2. Key steps in the reconfiguration process include identifying sites that need updating, checking the combiner filter model, balancing the receive signal path, and freeing one of the receive paths for use with new 3G equipment by rerouting the signal from the primary antenna. 3. Special attention must be paid to properly terminating unused ports, balancing the receive signal levels, and selecting the appropriate configuration based on the combiner filter type to avoid interference between transmit and receive signals.
