    en.wikipedia.org/wiki/2.4_GHz_radio_use

    Using cordless phones that do not use the 2.4 GHz band. Using the 5 GHz band. DECT 6.0 (1.9 GHz), 5.8 GHz or 900 MHz phones, commonly available today, do not use the 2.4 GHz band and thus do not interfere. VoIP/Wi-Fi phones share the Wi-Fi base stations and participate in the Wi-Fi contention protocols.

    A rooftop 1 watt Wi-Fi amp, feeding a simple vertical antenna on the left. Another way of adding range uses a power amplifier. Commonly known as "range extender amplifiers" these small devices usually supply around 1 ⁄ 2 watt of power to the antenna. Such amplifiers may give more than five times the range to an existing network.

    en.wikipedia.org/wiki/Antenna_amplifier

    In electronics, an antenna amplifier (also: aerial amplifier or booster) is a device that amplifies an antenna signal, usually into an output with the same impedance as the input impedance. Typically 75 ohm for coaxial cable and 300 ohm for twin-lead cable. An antenna amplifier boosts a radio signal considerably for devices that receive radio ...
