WiMAX Technology

WiMAX is also one of the emerging technologies that provide us high speed mobile data and telecommunication services. WiMAX stands for Worldwide Interoperability for Microwave Access and it is based on IEEE 802.16 standards. It works same as Wi-Fi does but it is more improved and efficient then WiFi and it can routedata to Wi-Fi that is Wi-Fi devices can take advantage of WiMAX connection. WiMAX technology provides higher speed connection up to 70 Mbps over the area of 30 miles. There is no need for line of sight connection between subscriber terminals and the base station in WiMAX technology and it can support hundreds if not thousands of subscribers from a single base station. It is also specified in 802.16 standards that it will supports low latency applications such as voice, video, and Internet access at the same time.

What is WiMAX Technology:

WiMAX technology is a telecommunications technology that offers transmission of wireless data via a number of transmission methods; such as portable or fully mobile internet access via point to multipoint links. The WiMAX technology offers around 72 Mega Bits per second without any need for the cable infrastructure

WiMAX is the next stage to a broadband as well as a wireless world, extending broadband wireless access to new locations and over longer distances, as well as considerably reducing the cost of bringing broadband to new areas. WiMAX technology offers greater range and bandwidth than the other available or forthcoming broadband wireless technologies such as Wireless Fidelity (Wi-Fi) and Ultra-wideband (UWB) family of standards

How WiMAX works:

The backhaul of the WiMAX is based on the typical connection to the public wireless networks by using optical fibre, microwave link, cable or any other high speed connectivity. In few cases such as mesh networks, Point-to-Multi-Point (PMP) connectivity is also used as a backhaul. Ideally, WiMAX should use Point-to-Point antennas as a backhaul to join subscriber sites to each other and to base stations across long distance.

A base station serves subscriber stations using Non-Line-of-Sight (NLOS) or LOS Point-to-Multi-Point connectivity; and this connection is referred to as the last mile communication.  Ideally, WiMAX should use NLOS Point-to-Multi-Point antennas to connect residential or business subscribers to the Base Station (BS). A Subscriber Station typically serves a building using wired or wireless LAN.
