2. Long-range Wi-Fi - Wikipedia

   en.wikipedia.org/wiki/Long-range_Wi-Fi

   Long-range Wi-Fi especially in the 2.4 GHz band (as the shorter-range higher-bit-rate 5.8 GHz bands become popular alternatives to wired LAN connections) have proliferated with specialist devices. While Wi-Fi hotspots are ubiquitous in urban areas, some rural areas use more powerful longer-range transceivers as alternatives to cell ( GSM , CDMA ...

3. Cantenna - Wikipedia

   en.wikipedia.org/wiki/Cantenna

   The 5.5 GHz cantenna dimensions are almost perfect in that they make a good fit for the standard TV satellite dish. The resulting setup is a low-cost high-quality high-gain antenna. [6] Such setups are widely used in wireless community networks for long-distance Wi-Fi links. Cantennas may be used with other RF devices such as wireless security ...

5. Antenna amplifier - Wikipedia

   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 ...

7. Amateur radio satellite - Wikipedia

   en.wikipedia.org/wiki/Amateur_radio_satellite

   Yagi antenna being used to communicate through an FM satellite. A number of low Earth orbit (LEO) OSCAR satellites use frequency modulation (FM). [6] These are also commonly referred to as "FM LEOs" or the "FM Birds". Such satellites act as FM amateur radio repeaters that can be communicated through using commonly available amateur radio equipment.
