Abstract WiMAXis an emerging technology for broadband wireless access. It offers both fixed and mobile broadband wireless Internet access. It promises very high data rates, high reliability, good efficiency and low cost. WiMAX enjoys strong industry support and standardization. Because of its low cost, WiMAXcan be used to provide broadband Internet access to suburban and rural areas and thus bridge the digital divide.

Introduction WI MAX Worldwide Interoperability for Microwave Access. WiMAX standards define formal specifications for deployment of broadband wireless metropolitan area networks (wireless MANs). Wireless MANs as defined in WiMAX standards provide wireless broadband access anywhere, anytime, and on virtually any device. It is an access technology that promises high data rates and wide coverage at low cost. WiMAX provides an impressive set of features like coverage radius of up to 50 km, data rates of up to 70 Mbps, ability to work in both licensed and license-exempt spectra and high spectral efficiency. WiMAX standards enjoy wide support from the industry, which is very crucial for the success of any technology.

Wimax Architecture ,[object Object], TCP/IP, VoIP, and SIP etc. Wimax network is offering air link interoperability and vendor for roaming. The multi vendor access from Wimax focused on higher level networking specifications for fixed wimax, mobile wimax, and portable wimax. The Architecture of wimax technology based on all IP platforms. ,[object Object], connectivity purpose like IEEE 802.16 radio specifics. ,[object Object], Voice, mandated dogmatic services as emergency and lawful interception. ,[object Object], interface with multi internetworking, media gateway, delivery of IP broadcasting such as MMS , SMS, WAP over IP.

Base station (BS): ,[object Object], The other functionality of BS is micro mobility supervision functions. Access service network (ASN): ,[object Object], combination of functional entities and equivalent significance flows connected with the access services. Connectivity Service Network (CSN) : ,[object Object], services for connectivity to Wimax clients. ,[object Object], database and gateway devices that support validation for the devices, services and user. The Connectivity Service Network also handled different type of task such as management of IP addresses.

HOW WIMAX WORKS In its simplest form, a WiMAX network consists of a WiMAX base station and multiple WiMAX subscriber stations (fixed or mobile). Figure using one fixed subscriber (shown as house) and one mobile subscriber (shown as passenger in a car). WiMAX base station is mounted on a tower. WiMAX subscriber station is a WiMAX customer premise equipment (CPE) that is located inside the house.

WiMAX base station on the tower communicates wirelessly with the WiMAX subscriber station located inside the house. WiMAX base station on the tower is physically wired to the Internet service provider's (ISP) network through fiber optic cables. At the ISP network terminus, data aggregated from all base stations are sent to the Internet backbone through high-speed high-capacity hick" fiber-optic cables. The transmission frequencies of Wimax technology from 2.3MHz to 3.5 GHz make it low price wireless network. ,[object Object],[object Object]

Wimax Features ,[object Object], access to mobile users. Wimax technology based on IEEE 802.16 standard and it is a telecommunication protocol offering full access to mobile internet across cities and countries with a wide range of devices. ,[object Object], easily scaling of data with possible bandwidth of channel. If the bandwidth of channels may from 1.25MHz to 10MHz bandwidth. ,[object Object], DSL and much easier to extend to suburban and rural areas . ,[object Object],[object Object]

Limitations of WiMAX Technology ,[object Object], cellular backhaul, hotspot, VoIP mobiles and broadband connection. ,[object Object], which is up to 30Mbit/s but if a user exist at the cell edge from the tower can obtain only 14Mbit/s speed. ,[object Object], could go down if more than one user exists in a single sector. Mostly user have a range of 2- to 8 or 12 Mbit/s services so for better result additional radio cards added to the base station to boost the capability as necessary.

Advantages Wimax Coverage ,[object Object], a time and manage sending and receiving of data at very high speed with full of network security. Wimax High Speed ,[object Object], demanded in hardly populated areas plus compacted areas. Disadvantages Lack of Quality ,[object Object], people trying to get access at the same tower so due to heavy traffic it is very hard to maintain high quality. Data Rate ,[object Object], satellite, cables etc are very slow.

WiMAX vs Wi-Fi ,[object Object], cost, speed, distance and so on. Wimax coverage is about 30 miles and Wi-Fi coverage is very limited to some small area. ,[object Object], get access to internet to your home or business, while Wi-Fi will be used inside in your local area network (LAN) for access to the internet. ,[object Object], networking (MAN). The base station of Wimax capable to provide access to business and hundred of homes, While Wi-Fi is providing only local area networking (LAN). Wimax Specifications ,[object Object]

Line-of-sightnot needed between user and base station

Frequency bands - 2 to 11 GHz and 10 to 66 GHz,[object Object]

Everything will be coordinated with Wimax .
