2. Aerial base station - Wikipedia

   en.wikipedia.org/wiki/Aerial_base_station

   An Aerial base station (ABS), also known as unmanned aerial vehicle (UAV)-mounted base station (BS), is a flying antenna system that works as a hub between the backhaul network and the access network.

3. MIMO-OFDM - Wikipedia

   en.wikipedia.org/wiki/MIMO-OFDM

   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 ...

4. 5G NR - Wikipedia

   en.wikipedia.org/wiki/5G_NR

   5G NR (5G New Radio) [1] is a radio access technology (RAT) developed by the 3rd Generation Partnership Project for the 5G (fifth generation) mobile network. [1] It was designed to be the global standard for the air interface of 5G networks. [ 2 ]

5. Air interface - Wikipedia

   en.wikipedia.org/wiki/Air_interface

   An antenna focuses the radio waves in a certain direction. Usually, this is called the main direction. Because of that, in other directions less energy will be emitted. The gain of an antenna, in a given direction, is usually referenced to an (hypothetical) isotropic antenna, which emits the radiation evenly strong in all directions.

6. 5G - Wikipedia

   en.wikipedia.org/wiki/5G

   An Android phone, showing that it is connected to a 5G network. In telecommunications, 5G is the fifth generation of cellular network technology, which mobile operators began deploying worldwide in 2019 as the successor to 4G. 5G is based on standards defined by the International Telecommunication Union under the IMT-2020 requirements, which outline performance targets for speed, latency, and ...

7. Wireless ad hoc network - Wikipedia

   en.wikipedia.org/wiki/Wireless_ad_hoc_network

   A wireless ad hoc network [1] (WANET) or mobile ad hoc network (MANET) is a decentralized type of wireless network. The network is ad hoc because it does not rely on a pre-existing infrastructure, such as routers or wireless access points. Instead, each node participates in routing by forwarding data for other nodes.

8. Multi-user MIMO - Wikipedia

   en.wikipedia.org/wiki/Multi-user_MIMO

   Multi-user MIMO (MU-MIMO) is a set of multiple-input and multiple-output (MIMO) technologies for multipath wireless communication, in which multiple users or terminals, each radioing over one or more antennas, communicate with one another.

9. Wireless mesh network - Wikipedia

   en.wikipedia.org/wiki/Wireless_mesh_network

   A wireless mesh network (WMN) is a communications network made up of radio nodes organized in a mesh topology. It can also be a form of wireless ad hoc network. [1] A mesh refers to rich interconnection among devices or nodes. Wireless mesh networks often consist of mesh clients, mesh routers and gateways. Mobility of nodes is less frequent.
