A cellular repeater (also known as cell phone signal booster or cell phone signal amplifier) is a type of bi-directional amplifier used to improve cell phone reception. [citation needed] A cellular repeater system commonly consists of a donor antenna that receives and transmits signal from nearby cell towers, coaxial cables, a signal amplifier, and an indoor rebroadcast antenna.
A passive system is less expensive to install and is best suited for smaller buildings where one or possibly two MNOs need to be enhanced within the building and are not usually installed in spaces over 100,000 square feet (9,300 m 2). Passive systems require the RF power to be balanced among all the coverage antennas so there is uniform signal ...

For very low-power systems, such as mobile phones, signal strength is usually expressed in dB-microvolts per metre (dBμV/m) or in decibels above a reference level of one milliwatt . In broadcasting terminology, 1 mV/m is 1000 μV/m or 60 dBμ (often written dBu). Examples. 100 dBμ or 100 mV/m: blanketing interference may occur on some receivers

His neighbor’s house sits on concrete pillars more than 20 feet tall. “I want to watch your house fall,” he joked to his neighbor as he tightened the strap holding the camera.
A mobile phone signal (also known as reception and service) is the signal strength (measured in dBm) received by a mobile phone from a cellular network (on the downlink). Depending on various factors, such as proximity to a tower , any obstructions such as buildings or trees, etc. this signal strength will vary.
