Wireless communication (or just wireless, when the context allows) is the transfer of information (telecommunication) between two or more points without the use of an electrical conductor, optical fiber or other continuous guided medium for the transfer. The most common wireless technologies use radio waves.
This ensures it can be applied to wireless voice telephony, mobile Internet access, fixed wireless Internet access, video calls and mobile TV technologies. CDMA2000 is a family of 3G mobile technology standards for sending voice, data, and signaling data between mobile phones and cell sites.
Wireless icon. A wireless network is a computer network that uses wireless data connections between network nodes. [1] Wireless networking allows homes, telecommunications networks, and business installations to avoid the costly process of introducing cables into a building, or as a connection between various equipment locations.

The design of cellular networks allows for seamless handover, enabling uninterrupted communication when a device moves from one cell to another. Modern cellular networks utilize advanced technologies such as Multiple Input Multiple Output (MIMO), beamforming, and small cells to enhance network capacity and efficiency.
[60] [65] Most of the essential elements of modern wireless networks are built from MOSFETs, including base station modules, routers, [65] telecommunication circuits, [66] and radio transceivers. [64] MOSFET scaling has led to rapidly increasing wireless bandwidth, which has been doubling every 18 months (as noted by Edholm's law). [60]
Multiple-input, multiple-output orthogonal frequency-division multiplexing (MIMO-OFDM) is the dominant air interface for 4G and 5G broadband wireless communications. It combines multiple-input, multiple-output technology, which multiplies capacity by transmitting different signals over multiple antennas, and orthogonal frequency-division multiplexing (OFDM), which divides a radio channel into ...
But SIGSALY was a top-secret communications system, so its existence was not known until the 1980s. In 1942, actress Hedy Lamarr and composer George Antheil received U.S. patent 2,292,387 for their "Secret Communications System", [ 9 ] [ 10 ] an early version of frequency hopping using a piano-roll to switch among 88 frequencies to make radio ...
MIMO technology can be used in non-wireless communications systems. One example is the home networking standard ITU-T G.9963, which defines a powerline communications system that uses MIMO techniques to transmit multiple signals over multiple AC wires (phase, neutral and ground). [3]
