Cell phone signal boosters (or cellular repeaters) are bidirectional amplifiers designed to boost the mobile phone reception using internal signal amplifiers, reception antennas and rebroadcast antennas. External antennas collect good cellular signal, and then it is transmitted to an amplifier, which retransmits the signal locally. This process results in much better signal. Rural areas often have problems with bad signal. Most service providers won’t make new towers in rural areas, because housing density is low. Cell phone signal boosters can solve this problem. Certain construction materials can block the signal. Read More
