    en.wikipedia.org/wiki/Internet_access

    Wi-Fi networks are built using one or more wireless antenna called access points. Many "modems" ( cable modems , DSL gateways or Optical Network Terminals (ONTs)) provide the additional functionality to host a LAN so most Internet access today is through a LAN such as that created by a WiFi router connected to a modem or a combo modem router ...

    Unlike most radio jammers, deauthentication acts in a unique way.The IEEE 802.11 (Wi-Fi) protocol contains the provision for a deauthentication frame.Sending the frame from the access point to a station is called a "sanctioned technique to inform a rogue station that they have been disconnected from the network".

The filtering is done voluntarily by the six largest providers of public Wi-Fi: Arqiva, BT, Sky, Nomad Digital, Virgin and O2, who together are responsible for 90% public Wi-Fi.

  9. Carrier-sense multiple access with collision avoidance

    en.wikipedia.org/wiki/Carrier-sense_multiple...

    Carrier-sense multiple access with collision avoidance (CSMA/CA) in computer networking, is a network multiple access method in which carrier sensing is used, but nodes attempt to avoid collisions by beginning transmission only after the channel is sensed to be "idle". When they do transmit, nodes transmit their packet data in its entirety.
