With the advent of wireless access in cities, businesses of all types have revolutionized the state of their setup and services. However, some customers in remote areas do not have access to the Internet or the network. In order to meet the needs of today’s era, there is no fixed concept, and the idea of WiMAX is very attractive. WiMAX is a technology with many solutions.
WiMAX specification
While the Wi-Fi specification is IEEE 802.11b, WiMAX was introduced as IEEE 802.16 and it revolutionized the computing world. Connect anywhere, anytime without boundaries. The hurdles have been overcome and WiMAX is now qualified to penetrate connections under all types of conditions. Previously, fixed WiMAX had been introduced, but extended mobile WiMAX quickly overtook its market as its features became more attractive and advantageous than fixed WiMAX.
bandwidth
WiMAX WiMAX supports greater bandwidth. For instant speed, the bandwidth of the FFT has been scaled to channel form. It needs to be considered that the channels have equal space so that the spectrum should be wider. This is known as a wide funnel, and a narrow funnel also results in less spending.
WiMAX range
The latest WiMAX standard (802.16e) specification provides a range in excess of 70 GHz. It provides many scalable orthogonal frequency-division accesses and shows much better performance than fixed standards.
WiMAX features
If we consider the characteristics of WiMAX, it has almost all means for connection and display. With the introduction of this new specification, the use of the Internet and coordination over the network has brought remarkable efficiencies to users.
flexibility
Mobility is the first benefit we see when using DSL or any other wired communication medium. Removal of restrictions or restrictions makes it easy to connect in any way no matter where the user stands. This mobility is not available under the closed premise of a specific location. Wimax coverage is now wider and can be used between cities or countries.
right to use
The connectivity provided by WiMAX lives up to the meaning of the term “last mile.” It supports near-overlapping connections for a wide range of access frequencies. This feature is most important as it supports service in remote rural areas.
flexibility
Rather, WiMAX is a universal mobile broadband. Not only does it support wireless connections, but you can transfer large amounts of data through it. Various services, such as voice over IP and especially triple play, can only use WiMAX. It stands alone as a formidable giant that can meet the standards of all services obtained using different devices. WiMAX replaces all these conveniences and delivers its services with confidence.
connect
After deploying WiMAX, forget to disconnect. WiMAX will be responsible and let you forget about Internet or network related problems. It fulfills its responsibilities through various means available in the market known as subscription units such as mobile phones, netbooks, iPods, etc. Today, the WiMAX service also supports game consoles. There are several ways to access the service using a Wi-Fi hotspot, the Ethernet port also supports WiMAX connections, and the phone jack is a convenient way to access this WiMAX service.
limit
After reading so many good points, one would think it’s the best option ever. However, Wimax also has some limitations that cannot be ignored.
speed/distance
Speed is inversely proportional to distance, because when you move away from the access point, you lose speed. The greater the distance, the slower the speed on a Wimax network.
Quality/Bandwidth
Performance depends on available bandwidth in Wimax network. If the bandwidth is divided into many different users operating simultaneously, it will inevitably reduce the quality of service.
What is WiMAX technology?
Wimax stands for Worldwide Interoperability for Microwave Access. Wimax technology is a telecommunication technology that provides wireless data transmission through multiple transport methods; such as mobile or fully mobile Internet access through point-to-multipoint links. Wimax technology provides approximately 72 megabits per second without requiring a wiring infrastructure.
The standard on which Wimax technology is based is IEEE 802.16, which is often referred to as broadband wireless access. The WiMAX Forum, named for the Wimax technology, was formed in mid-June 2001 to promote compliance and interoperability of the Wimax IEEE 802.16 standard. Wimax technology is truly standards-based, providing last-mile broadband access as an alternative to traditional cable and DSL lines.
Wimax technology (802.16) is often misunderstood as mobile WiMAX, 802.16d, fixed WiMAX and 802.16e. Actually 802.16-2004 or 802.16d was developed as a standard by a third party and it is also called Fixed WiMAX because the standard is only missing because of non-portability, that’s why it is often called Fixed WiMAX. During the maturity of Wimax technology (802.16), the above-mentioned 802.16d has been revised many times, and they called this revised standard 802.16e. 802.16e introduced mobility and other features in another standard, also known as Mobile WiMAX.
Today less than one in five people in the developed world, or even fewer, have access to broadband globally to a tiny minority. Existing technologies such as Digital Subscriber Line (DSL), cable and fixed wireless are dwarfed by expensive installations, loop length issues, upstream upgrade issues, limitations, poor visibility and scalability.
Wimax (802.16) is the next phase in the broadband and wireless world, bringing broadband into new territories by extending broadband wireless access to new locations and greater distances, and dramatically reducing costs. Wimax technology (802.16) offers greater range and bandwidth than other existing or upcoming broadband wireless technologies, such as true wireless standards (Wi-Fi) and ultra-wideband (UWB). It provides a wireless alternative to cable data service interface specification (DOGS1S), Digital Subscriber Line (DSL), T-Carrier and E-Carrier (Tx/Ex) systems, and fiber optic carrier grade for cable modem and last-mile backhaul deployments Technology (OC-x). (Jiffy Networks, 2006)
The joint initiative for urban wireless networks started with so-called fixed wireless networks, as envisioned in 802.16. The backbone of the base station is connected to the public network, and each base station carries hundreds of fixed user stations, which can be either a public hotspot or a firewall enterprise network. Later in the 802.16e development cycle, Wimax (802.16) is expected to promote mobile wireless technology, especially direct wireless transmission to mobile end users, which will be similar to the function of General Packet Radio Service (GPRS) and radio once transmission technology ( RTT) provided by the mobile phone company.
New organizations and individuals are increasingly adopting broadband, while those already using broadband are increasingly dependent on it and demanding better service and additional benefits. .To support this particular new requirement, Wimax (802.16) has emerged as a possible solution, which holds great promise for the future of wireless communications due to its inherent characteristics. (Terry Robinson, 2005)
There has been a lot of excitement about Wimax (802.16) and the impact this standards-based wireless networking technology will have on the broadband access market. All this hype has created enormous expectations, and the industry has responded with extraordinary enthusiasm and commitment to taking broadband to the next level with Wimax (802.16).
How WiMAX works
Wimax (802.16) is based on typical connections to public wireless networks using fiber optics, microwaves, cables, or any other high-speed connection. In some cases, such as networking, a point-to-multipoint (PMP) connection is also used as a supporting method. Ideally, Wimax (802.16) should use point-to-point antennas to aid in connecting subscriber sites to each other and to base stations over long distances.
A wimax base station that serves subscriber stations using a non-line-of-sight (NLOS) or LOS point-to-multipoint connection; this connection is called last-mile communication. Ideally, Wimax (802.16) should use point-to-multipoint NLOS antennas to connect residential or business users to a Wimax base station (BS). Subscriber stations (Wimax CPE) typically serve buildings using wired or wireless LANs. (Steven J. Vaughan-Nichols, June 2004)
