What is WiMAX Technologies?

WiMAX (Worldwide Interoperability for Microwave get access to) is a telecommunications protocol that presents repaired and fully wireless Internet access. The current WiMAX revision provides up to 40 Mbit/s with the IEEE 802.16m revise anticipated to offer up to 1 Gbit/s repaired speeds. The title "WiMAX" was conceived by the WiMAX Forum, which was formed in June 2001 to encourage conformity and interoperability of the standard. The forum describes WiMAX[3] as "a standards-based expertise enabling the consignment of last mile wireless broadband get access to as an alternative to twisted cord and DSL".

Uses

The bandwidth and range of WiMAX make it apt for the following promise applications:

Providing portable mobile broadband connectivity over towns and nations through a variety of devices.

Providing a wireless alternate to twisted cord and DSL for "last mile" broadband access.

Providing facts and figures, telecommunications (VoIP) and IPTV services (triple play).

Providing a source of Internet connectivity as part of a enterprise continuity plan.

Broadband

Companies are establishing WiMAX to supply wireless broadband or at-home broadband connectivity over whole towns or countries. In many situations this has produced in competition in markets which normally only had access to broadband through an existing incumbent DSL (or alike) operator.

Additionally, given the somewhat low cost to deploy a WiMAX mesh (in comparison to GSM, DSL or Fiber-Optic), it is now likely to supply broadband in places where it might have been previously economically unviable.

Backhaul

WiMAX is a likely replacement nominee for cellular telephone technologies such as GSM and CDMA, or can be utilised as an overlay to boost capacity. Fixed WiMAX is furthermore advised as a wireless backhaul technology for 2G, 3G, and 4G systems in both developed and evolving nations.[6][7]

In North America, backhaul for built-up cellular operations is typically supplied by one or more copper cable line T1 connections, while isolated cellular procedures are occasionally backhauled by satellite. In most other regions, built-up and rural backhaul is usually supplied by microwave links. (The exclusion to this is where the network is operated by an incumbent with prepared get access to to the copper network, in which case T1 lines may be used.) WiMAX is a broadband stage and as such has much more substantial backhaul bandwidth obligations than legacy cellular applications. Therefore, customary copper wire line backhaul answers are not appropriate. Consequently the use of wireless microwave backhaul is on the rise in North America and existing microwave backhaul connections in all regions are being upgraded.[8] capabilities of between 34 Mbit/s and 1 Gbit/s are regularly being established with latencies in the order of 1 ms. In many situations, operators are aggregating sites using wireless technology and then giving traffic on to fiber networks where convenient.

Connecting to WiMAX

There are numerous apparatus on the market that provide connectivity to a WiMAX ...
