ITU-R : International Telecommunication Union Radiocommmunication & Local entities such as FCC (Federal Communications Commission) set the rules for what the user can do with a radio transmitter.These organisations manage and regulate ferquencies, power level and transmission methods.
This worldwide wide organizationi defined which portion of spectrum will be adapted to each type transmission use case. It also define spectrum segments, names, and assigns communication access to each segment.

IEEE : The institute of Electrical and Electronic Engineers: Create standard for compatibility and coexistence between networking equipement. The IEEE standards must adhere to the rules of the communications organizations, such as the FCC.
It also designs the transmission mechanisms of Wi-Fi.
IETF : The Internet Engineering Task Force: responsible for creating Internet standards. Many of these standards are integrated into the wireless betworking and security protocols and standards.
ISO - International Standards Organisation - Created the OSI model
Wi-Fi Alliance : performs certification testing to make sure wireless networking equipment conforms to the 802.11 WLAN communication
guidelines, which are similar to the IEEE 802.11-2012 standard.
The International Organization for Standardization (ISO) created the Open Systems Interconnection (OSI) model, which is an architectural model for data communications.
FCC - The Federal Communications Commission is an independent agency of the United States government created by statute to regulate interstate communications by radio, television, wire, satellite, and cable.
The FCC maintains jurisdiction over the areas of broadband access, fair competition, radio frequency use, media responsibility, public safety, and homeland security.
ETSI - uropean Telecommunication Standards Institute , define the set of spectrum usage regulations in Europe.
WPA2 Security - Security Standardisation
CCX - Cisco Compatible Extensions - Allows chipset different Vendors to be compliant with Cisco Proprietary Protocols.
