The system has two main components: A WiMax tower and a WiMax receiver. Like Wi-Fi, WiMax can connect directly to the Internet by sending a signal from a WiMax tower to a WiMax-enabled computer via a wired connection.

What are the two parts of WiMAX system?

This is what allows WiMAX to achieve its maximum range. Below, at figure Figure 4., we can see how WiMAX works. Typically, a WiMAX system consists of two parts: Page 15 – A WiMAX Base Station: Base station consists of indoor electronics and a WiMAX tower.

What is the principle behind WiMAX communication?

Mobile WiMAX uses Orthogonal frequency division multiple access (OFDM) as a multiple-access technique, whereby different users can be allocated different subsets of the OFDM tones.

Where do we use WiMAX?

WiMax developed to provide wireless broadband access to buildings, either in competition to existing wired networks or alone in currently unserved rural or thinly populated areas. It can also be used to connect WLAN hotspots to the Internet. WiMAX is also intended to provide broadband connectivity to mobile devices.

What are the advantages and disadvantages of WiMAX?

It can also provide a wireless alternative to cable, DSL, and broadband access. The main advantages of WiMAX are that it allows high-speed wireless internet connection over the broad coverage area, while main disadvantages of WiMAX is still much bigger installation coast and also operational cost.

What are some of the features of the WiMAX standard?

WiMAX – Salient Features

• Two Type of Services. WiMAX can provide two forms of wireless service −
• OFDM-based Physical Layer.
• Very High Peak Data Rates.
• Scalable Bandwidth and Data Rate Support.
• Adaptive Modulation and Coding (AMC)
• Link-layer Retransmissions.
• Support for TDD and FDD.
• WiMAX Uses OFDM.

What are the three basic profiles supported by WiMAX?

The WiMAX Forum currently supports continued rapid WiMAX user adoption in the 2.3 GHz, 2.5 GHz, and 3.5 GHz frequency bands, with additional spectrum bands to come.

What is the difference between WiFi and WiMAX?

WiMax handle a larger inter-operable network. WiMax can be used to provide internet services such as mobile data and WiFi spots….Difference between WiFi and WiMax:

What are the benefits of WiMAX?

Infrastructure: WiMAX infrastructure is very easy and flexible therefore it provides maximum reliability of network and consent to actual access to end-users. 5. Low cost network: WiMAX provides a low cost network substitute to Internet services offered via ADSL, modem or local area network.

What are the limitations of WiMAX?

1. Lack of Quality: The WiMAX network has lack of quality service because there are hundreds of people trying to get access at the same tower so due to heavy traffic it is very hard to maintain high quality. 2. WiMAX range: The other disadvantage of WiMAX network is range.

Why do we need to define the WiMAX network architecture?

In order that elements of network equipment can be used from different suppliers, it is necessary to define the WiMAX network architecture that is common to all WiMAX networks. In this way economies of scale can be gained along with robust networks that are able to perform reliably under all conditions.

What version of WiMAX is used for WiMAX?

802.16 is used for WiMAX with the features: •Uses wireless link with microwave or millimeter waves. •Uses licensed spectrum Provides public network service to fee

Is WiMAX an alternative broadband?

Based on IEEE 802.16 WiMax is claimed as an alternative broadband rather than cable and DSL. This paper is a quick technical overview and covers: WiMAX overview Fundamental Concept Technology Standard update and WiMAX archi tecture Network and Node Architectures Physical Layer MAC Layer Index Terms—Broadband, IEEE 802.16, WiMAX. P

What is the difference between WiMAX and Wi-Fi?

Comparison 1 WiMAX is a long range system, covering many kilometres, that uses licensed or unlicensed spectrum to deliver connection to a network, in most cases the Internet. 2 Wi-Fi uses the 2.4 GHz and 5 GHz radio frequency bands to provide access to a local network. 3 Wi-Fi is far more popular in end-user devices.
