Cellular signal enhancer

摘要: A low-cost user portable signal enhancer unit for extending service coverage of wireless communications to a in desired area limited coverage. The enhancement supports an increase power levels allow communication usage location, such as small office or home environment where the original cellular signals are weak unreliable. base station is enhanced by bi-directional amplifier device (BDA), which receives signal, amplifies and retransmits amplified first path close proximity. also second separate path. Dual polarized antennas can receive transmit respective at opposite polarizations isolation signals.
