What is WiMax and its Role in the Technology Field

Wireless network infrastructure has become just another connection method for corporate and home users alike. This rapid acceptance can be attributed from:

Nowadays there are also keyboards and mousses that can be connected via Wi-Fi. It’s a wireless technology that allows computers and other type of electronic devices to communicate through a wireless signal. Wi-Fi is the most common way to connect computers to wireless networks.

WiMAX can transmit speeds up to 50km at 280mbps, and provides options for use in point to point and multipoint configurations.

Wireless DSL is a type of fixed wireless which requires a line of sight between communicating transmitters. Unfortunately; this makes its application limited, because in order to be effective, it requires tall buildings or towers. Most multitenant buildings such as hotels, remote office buildings and apartments use this. Transmitters are what connect the building to the ISP, and the DSL used inside the building connects to the wireless transceiver. Fixed wireless can be point to point or multipoint. Satellite is another form of fixed wireless. Both the point-to-point and multipoint versions have data transmissions ranging from 1.5 to 54 Mbps, dependent on the vendor. Mobile wireless service can be set up by the provider in a package one the WAP network protocol is fixed to support it. (Wireless Application Environment) (Fitzgerald, 349-350).

In the recent years, wireless technologies have taken a new dimension in the ways society lives. Wireless broadband is available to everyone. Whether the users are at home, driving the car, sitting in the park, and it would even work while people are a pleasure boat ride in the middle of a lake. And because of this, the need to have information at any time and be connected in all places, all the time has been satisfied.

The innovation behind WiFi is a very creative and amazing idea that has taken over the 21st century. WiFi was created for people to connect with one another in a faster and more efficient way. WiFi was

wireless network and the most widely available wireless broadband network in the country. The U.S.

A WLAN is a network that helps to attach two or more devices using wireless techniques like spread spectrum. It access in limited area like schools, colleges, organizations, offices, and computers labs etc. This helps the clients to access even while roaming near about that area and still they remain connected with network.

Examples of wireless networks include cell phone networks, Wi-Fi local networks and terrestrial microwave networks.

In the case, we could know that WTC had high-speed broadband connections through WiMAX to track every athlete. Broadband is the technology of internet connections, which could transmit data at a high speed of over 200 kilobytes. WiMAX technology belongs to wireless broadband technology, which could transmit wireless data in wide range areas (Baltzan & Welsh, 2015). Although WiMAX could transmit data at high speeds and operate in a big

The line-of-sight service, where a fixed dish antenna points straight at the WiMAX tower from a rooftop or pole, the line-of-sight connection is stronger and more stable, so it's able to send a lot of data with fewer errors. Line-of-sight transmissions use higher frequencies, with ranges reaching a possible 66 GHz. At higher frequencies, there is less interference and lots more bandwidth.

The IEEE 801.16 classified into two layers that are physical layer (PHY) and medium access control (MAC) layer. The PHY help four particulars which are single carrier (MAN-SC), Quadrature Amplitude Modulation (QAM), Time Division Duplexing (TDD) and orthogonal frequency division multiplexing (OFDM). WiMAX PHY is founded on orthogonal frequency division multiplexing to creating transmitter to achieve high speed data transfer. Physical layers are intended for non-line of sight operation in frequency bands lower 11 GHz.

Wireless networks serve as the transport mechanism between devices and among devices and the traditional wired networks (enterprise networks and the Internet). Wireless networks are many and diverse but are frequently categorized into three groups based on their coverage range: Wireless Wide Area Networks (WWAN), Wireless Local Area Network (WLANs), Wireless Personal Area Network (WPAN )and etc.

As multimedia services gain momentum, new broadband access technologies emerge to address the specific requirements of such services. To this purpose, there exist several traditional first mile solutions, leveraging cables or fibers, and a novel family of Broad¬band Wireless Access (BWA) technologies. Among BWA tech¬nologies, the IEEE 802.16 standard [1] is considered the leading technology for the provision of Internet-based broadband services in wide

Wi-Fi - a trademark of Wi-Fi Alliance for wireless networks based on the standard IEEE 802.11. The acronym Wi-Fi (from the Wireless Fidelity, which can be literally translated as "the quality of the wireless") is currently developing as a family of standards for the transmission of digital data radio streams. It is still often hears that the wireless network is not secure compared to wired solutions. At the present stage of Wi-Fi technology‘s development that is not true. Simply security needs to be addressed (to design and maintain), as in the case of a wired network.
