Answer:
WiMAX (Worldwide Interoperability for Microwave Access) is a family of wireless broadband communication standards based on the IEEE 802.16 set of standards, which provide multiple physical layer (PHY) and Media Access Control (MAC) options.The name "WiMAX" was created by the WiMAX Forum, which was formed in June 2001 to promote conformity and interoperability of the standard, including the definition of predefined system profiles for commercial vendors.
Answer:
The ‘World Interoperability for MicroAcess, Inc. (WiMAX)’ forum, an industry group, focuses on creating advanced technology solution for high speed wide area internet access.
ii. The WiMAX product certification program ensures interoperability between WiMAX equipment from vendors worldwide.
iii. WiMAX can serve as a backbone for 802.11 hotspots for connecting to the internet. Alternatively, users can connect mobile devices such as laptops and handsets directly to WiMAX base stations. Mobile devices connected directly can achieve a range of 4 to 6 miles.
iv. There are 2 types of WiMAX, fixed WiMAX(IEEE 802.16d-2004) and mobile WiMAX(IEEE802.16e-2005). Fixed WiMAX is a point-to-multipoint technology, whereas mobile WiMAX is a multipoint-to-multipoint technology, similar to that of a cellular infrastructure.
