The solution for weak indoor signal in small households is generally weak for areas with relatively complex indoor structures, far from windows, and basement mobile phone signals. And the outdoor signal is good. A 5D-FB coaxial cable can be used to connect the receiving antenna and the signal booster host. An omnidirectional coverage antenna is installed in the center every 100 square meters indoors. At the output port of the signal amplifier, a 5D-FB coaxial cable is used to connect the power divider or coupler to distribute the signal output by the amplifier and connect it to the coverage antenna.

Amplitec's C17L series mobile signal amplifier is a very low-cost solution. The C17L series signal booster is available in single band, dual band, triple frequency, and multi band models.

Install an signal amplifier host with a downlink output power of 20dBm between devices; Install an omnidirectional ceiling mounted antenna at the center of the ceiling in areas with weak signals, covering 360 degrees in all directions; The receiving antenna is installed in the direction where the signal is strong on the rooftop.
