What are the basic components of WiMAX?
WiMAX requires two main components to form an operational network:
- Base Station (BS), which can serve as a repeater or can be connected to the Internet backbone.
- Subscriber/end user, enjoying broadband wireless access through the base station.
What is WiMAX how it works?
WiMAX is an alternative to wired broadband, such as DSL and cable modem, and according to the forum, “provides fixed, nomadic, portable and, soon, mobile wireless broadband connectivity without the need for direct line-of-sight with a base station.”
What are the two parts of WiMAX system?
Typically, a WiMAX system consists of two parts:
- A WiMAX Base Station: Base station consists of indoor electronics and a WiMAX tower.
- A WiMAX Receiver – The receiver and antenna could be a stand-alone box or a PCMCIA card that sits in your laptop or computer.
What technology does WiMAX use?
WiMAX technology is a wireless broadband communications technology based around the IEE 802.16 standard providing high speed data over a wide area. The letters of WiMAX stand for Worldwide Interoperability for Microwave Access (AXess), and it is a technology for point to multipoint wireless networking.
What is WiMAX base station?
A WiMAX base station consists of indoor electronics and a WiMAX tower similar in concept to a cell-phone tower. A WiMAX base station can provide coverage to a very large area up to a radius of 6 miles. Any wireless device within the coverage area would be able to access the Internet.
What is the bandwidth of WiMAX?
Under optimal conditions, WiMax offers data-transfer rates of up to 75 megabits per second (Mbps), which is superior to conventional cable-modem and DSL connections. However, the bandwidth must be split among multiple users and thus yields lower speeds in practice.

Does WiMAX need line-of-sight?
While many technologies currently available for fixed broadband wireless can only provide line of sight (LOS) coverage, the technology behind WiMAX has been optimized to provide excellent non line of sight (NLOS) coverage.
