Wireless protocols A MAC protocol for a wireless LAN provides two types of data-transfer Service Access Points (SAP): network and native. The network SAP offers an access to a legacy network protocol (e.g., IP). The native SAP provides an extended service interface that may be used by custom network protocols or user applications capable of fully exploiting the protocol specific Quality of Service (QoS) parameters within the cell service area. Broadband Radio Access Integrated Network (BRAIN) is used for millimeter wave band multimedia communications....

WiMAX operates on the same general principles as Wi-Fi — it sends data from one computer to another via radio signals. A computer (either a desktop or a laptop) equipped with WiMAX would receive data from the WiMAX transmitting station, probably using encrypted data keys to prevent unauthorized users from stealing access.
