The UMTS Signal Boosters from Raygnal may be set up to amplify any 2G network system, including GSM900, DCS1800, CDMA850, PCS1900, and others. Applications include areas with poor signals, such as the country, the mountains, or the villages.
There could be several reasons why an UMTS signal booster cannot work even if the phone signal bar is full:
1. The signal booster might be defective or malfunctioning.
2. The signal booster might not be installed correctly and is not properly grounding.
3. The signal booster might not be compatible with the carrier network or frequency bands used in the area.
4. The signal booster might not be powerful enough to boost the signal in the specific location.
5. The signal booster might be receiving interference from other devices or noise sources.
6. The phone signal bars may not always indicate the true strength of the signal, and a full signal bar may not necessarily indicate strong signal quality.
It is important to identify the exact cause of the problem and address it accordingly to ensure a reliable boost to the signal.
