1.1 Describe WLAN organizations and regulations

 

 

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.

 

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.

 

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.

 

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.
