If someone is trying to sell you 4G wireless these days, don't believe them.

The truth is, neither WiMax nor LTE (Long-Term Evolution) qualify as 4G (fourth-generation) technologies, according to the International Telecommunication Union Radiocommunication Sector (ITU-R). On Thursday, the group announced it had finished its assessment of submissions for the 4G standard, also called IMT-Advanced. Based on that group's decision, to really be selling 4G, carriers will have to get going with one of two future technologies, called LTE-Advanced and WirelessMAN-Advanced. The latter, also known as IEEE 802.16m, will form the basis of WiMax Release 2.

The IEEE 802.16 Working Group is the IEEE group for Wireless Metropolitan Area Networks (WMANs), in particular Part 16: Air Interface for Fixed Broadband Wireless Access Systems. The working group develops standards and recommended practices to support the development and deployment of fixed broadband wireless access systems.

The Institute of Electrical and Electronic Engineer

The IEEE creates the industry standards in the United States and in many parts of the world. The IEEE created the 802.11-2007 standard and subsequent WLAN amendments. The IEEE creates the standards within the confines of regulatory domains. The IEEE website is www.ieee.org
The body responsible for IEEE 802.3 (Ethernet), 802.11 (WLAN), and many other specifications. The IEEE creates standardized data communications protocols for Layers 1 and 2 of the OSI model.(Open System Interconnection)

Layers of OSI Model

Layer 7 | Network Application
Layer 6 | Presentation
Layer 5 | Session
Layer 4 | Transport
Layer 3 | Network
Layer 2 | Data - Link ( is your Ethernet protocol and Ethernet addressing * MAC Address
*LLC sublayer
*MAC sublayer
Layer 1 | Physical - traffic is going across your network medium ( such as your network cable or your wireless air waves)
