How does Cel-Fi differ from a broadband repeater?

Cel-Fi does several things:
1. A Cel-Fi device only boosts specific UMTS carrier frequencies (5MHz channels, up to 3) and not the whole band.
2. Cel-Fi will only boost the pre-configured UMTS carrier frequencies if they actually contain a valid UMTS signal and are for the correct network (i.e. the Cel-Fi device can lock onto the UMTS pilot channel, like a phone, and read broadcast information, such as the network identity or ‘PLMN-ID’ then determine what to boost)
3. Cel-Fi automatically limits its boost when close to the base station (based on a calculation of the actual RF path-loss) and so will never boost thermal noise to a level where the base station’s uplink performance will be damaged
4. Cel-Fi is unconditionally stable and will never oscillate – oscillation is usually a common and serious problem with traditional repeaters which causes power spikes that degrade the base station’s uplink performance.
