The document provides an overview of WiMAX (Worldwide Interoperability for Microwave Access), a wireless technology that provides broadband connectivity. It discusses WiMAX architecture which includes base stations, access service network gateways, and connectivity service networks. WiMAX works through WiMAX base stations and receivers to provide portable mobile broadband across large areas. It offers benefits like high-speed broadband access, reliability, and support for mobility and roaming. WiMAX provides longer range connectivity compared to WiFi networks and is suited for metropolitan area networks rather than local area networks.

WIMAX Architecture
• Base station (BS): The BS is responsible for providing the air interface to
the MS. Additional functions that may be part of the BS are micromobility
management functions,
• Access service network gateway (ASN-GW): The ASN gateway typically
acts as a layer 2 traffic aggregation point within an ASN.
• Connectivity service network (CSN): The CSN provides connectivity to the
Internet, other public networks, and corporate networks. The CSN is
owned by the NSP and includes AAA servers that support authentication
for the devices, users, and specific services. The CSN is also responsible
for IP address management, support for roaming between different NSPs,
location management between ASNs, and mobility and roaming between
ASNs.

8. Use of Wimax
Providing portable mobile broadband connectivity across
cities and countries through a variety of devices.
Providing a wireless alternative to cable and DSL(digital
subscribe line) for last mile broadband access
Providing Data, telecommunication (VoIP) and (IPTv)
services (triple play)

Wimax vs WiFi
Wimax Vs WiFi
• Wimax coverage is about 30 miles . Coverage is limited to 1.5 miles
• It provides metropolitan area network(MAN) Provides local area networkt
• It is a high cost network Low cost network
• It offers high speed of broadband access Offers short range of data transfer
