Introduction to Same Band Combining of UMTS & GSM

The advantage of using a Same Band Combiner (SBC) is that infrastructure such as feeders, tower mounted amplifiers and antennas can be shared by multiple base stations or node-Bs. This means less equipment is required per sector with the benefits of lower operational & capital expenditure (opex/capex) as well as more efficient use of tower space.

Range to Fault Technology

Passive intermodulation (PIM) has been recognized as a problem in communications systems for nearly 50 years. New technology is helping cut down on the amount of time it takes to find the source of the problem. Learn how Range To Fault (RTF) analysis can accurately predict the location of multiple static PIM sources within the RF infrastructure.
