Fixed wireless is the operation of wireless communication devices or systems used to connect two fixed locations (e.g., building to building or tower to building) with a radio or other wireless link, such as laser bridge. [1] Usually, fixed wireless is part of a wireless LAN infrastructure. The purpose of a fixed wireless link is to enable data ...
The cable connecting the receiver to the LNB are of the low loss type RG-6, quad shield RG-6, or RG-11. [22] RG-59 is not recommended for this application as it is not technically designed to carry frequencies above 950 MHz, but will work in many circumstances, depending on the quality of the coaxial wire.

Wi-Fi (/ ˈ w aɪ f aɪ /) [1] [a] is a family of wireless network protocols based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves.
A 1 Gbit/s point-to-point millimeter-wave link installed in the UAE A point-to-point wireless unit with a built-in antenna at Huntington Beach, California. With the exception of passive optical networks, modern Ethernet is exclusively point-to-point on the physical layer – any cable only connects two devices.
Some devices with dual-band wireless network connectivity do not allow the user to select the 2.4 GHz or 5 GHz band (or even a particular radio or SSID) when using Wi-Fi Protected Setup, unless the wireless access point has separate WPS button for each band or radio; however, a number of later wireless routers with multiple frequency bands and ...
The direct-sequence modulation makes the transmitted signal wider in bandwidth than the information bandwidth. After the despreading or removal of the direct-sequence modulation in the receiver, the information bandwidth is restored, while the unintentional and intentional interference is substantially reduced.

U-verse TV is an internet protocol television (IPTV) service operated by DirecTV.Launched on June 26, 2006, U-verse was originally a triple play package that included broadband Internet (now AT&T Internet or AT&T Fiber), IP telephone (now AT&T Phone), and IPTV (U-verse TV) services in 22 states.
Long-distance electromagnetic telegraph systems from 1820 onwards [a] used two or more wires to carry the signal and return currents. It was discovered by German scientist C.A. von Steinheil in 1836–1837, that the ground could be used as the return path to complete the circuit, making the return wire unnecessary. [2]
