For example, a cell phone signal booster made for a very large home (up to 7,500 square feet) can cost up to $1,000, whereas boosters made for smaller homes (up to 3,500 square feet) can go for ...
The lower the frequency, the easier a signal can travel—AM radio tops out at about 1.6 megahertz, for example, and you can keep the same AM station on the radio as you travel extremely far from ...
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.
