Worldwide inter-operability for microwave access or wimax is standard developed for wireless communications that has been designed so as to deliver data rates of 30-40 mbps. The update in the technology in the year 2011 upgraded the technology to provide around 1 gbps for the stations that were fixed.
- The Wimax forum is responsible for naming the technology as Wimax.
- This forum was formed in the year of 2001 for the promotion of the inter-operability and conformity of this standard.
- The Wimax has been defined by the forum as the technology based up on standards that enable the last mile wireless broadband delivery as alternative for the DSL and the cable thing.
- The IEEE 802/ 16’s interoperability implementations are referred to as the WiMax.
- The wimax forum has ratified this family of standards.
- By virtue of the certification provided by this forum, the vendors are able to sell mobile and fixed products that are wimax certified.
- This is done for ensuring that a level of inter-operability is maintained at par with the other products that have been also certified for the same profile.
- The ‘fixed wimax’ is the name given to the original IEEE 802.16 standards.
- ‘Wifi on steroids’ is the term used to refer to WiMax sometimes.
It has got a number of applications such as in:
Ø Broadband connections
Ø Cellular back-haul
Ø Hot spots and so on.
- This technology shares some similarity with the Wifi technology however, this one is more capable of transmitting data at greater distances.
It is because of its range and bandwidth that the WiMax is suitable for the following applications:
Ø Provides services such as the IPTV services and VoIP (telecommunications services).
Ø Provides mobile broadband connectivity that is portable across the cities and countries and that can be accessed via different kinds of devices.
Ø Provides an alternative for DSL and cable in the form of wireless last mile broadband access.
Ø Acts as a source of internet connectivity.
Ø Metering and smart grids.
- This technology can be used at home for providing internet access across the countries.
- This has also caused a rise in the market competition.
- The WiMax is even economically feasible.
- Mobile wimax has been used as a replacement for the technologies like CDMA, GSM that are cellular phone technologies.
- The technology has also been used as an overlay for increasing the capacity.
- The fixed wimax is now used for 2g, 3g and 4g networks as a wireless back-haul technology in almost all the nations whether they are developed or developing.
- In some states of North America, this technology is provided through a numbered of copper wire line connections.
- On the other hand, the technology is back hauled via satellites in case of the remote cellular operations.
- While in other cases even microwave Links are used.
- The bandwidth requirements of the WiMAX demand more substantial back-haul when compared to other legacy cellular applications.
- In some of the cases, the sites have been aggregated by the operators by use of Wireless Technology.
- The traffic is then introduced to the fiber networks as per the convenience.
- The technologies that provide triple play services are directed compatible with the WiMAX.
- These services might include multi-casting and quality of service.
- WiMax has been widely used for providing assistance in the communications.
- The Intel Corporation has donated the hardware for WiMax technology for assisting the FCC (federal communications commission) and FEMA etc.
- The subscribers’ stations or SS are the devices which are used for connecting to a WiMAX Network.
- These devices might be portable such as the following:
> Handsets and smart phones
> PC peripheral such as USB dongles, PC Cards and so on.
> Embedded devices in notebooks.
