WIMAX TECHNOLOGY Presented by VIKAS

QUICK GLANCE : 

QUICK GLANCE WIMAX stands for Worldwide Interoperability for Microwave Access, the stage of mobile communications that will enable things like IP-based voice, data, gaming services and high quality streamed multimedia on portable devices with cable modem-like transmission speeds.

HISTORY

What is WIMAX ? : 

What is WIMAX ? WIMAX is a wireless digital communications system also known as IEEE 802.16. WIMAX can provide broadband wireless access up to 30 miles(50 km) for fixed stations and 3-10 miles(5-15 km) for mobile stations. It allows a user, to browse the internet on a laptop without physically connecting it to a router. It involves microwaves for the transfer of data wirelessly.

Wireless Technologies : 

Wireless Technologies Wide Area Network Metropolitan Area Network Local Area Network Personal Area Network Fixed WIMAX & 2G / 3G Mobile WIMAX & 3G Evol Wi-Fi WiMedia & BT

WIMAX SPECIFICATION : 

WIMAX SPECIFICATION 802.16a Uses the licensed frequencies from 2 to 11 GHz Supports Mesh network 802.16b Increase spectrum to 5 and 6 GHz Provides QoS( for real time voice and video service) 802.16c Represents a 10 to 66GHz 802.16e Addresses on Mobile Enable high-speed signal handoffs necessary for communications with users moving at vehicular speeds

Architecture : 

Architecture IEEE 802.16 Protocol Architecture has 4 layers: Convergence, MAC, Transmission and physical, which can be mapped to two OSI lowest layers: physical and data link

HOW IT WORKS ? : 

HOW IT WORKS ? A WIMAX tower station can connect directly to the internet using a high-bandwidth, wired connection. It can also connect to another WIMAX tower using a line-of-sight, microwave link. This connection to a second tower, along with the ability of a single tower to cover up to 3,000 square miles, is what allows WIMAX to provide coverage to remote rural areas.

TYPES… : 

TYPES… Fixed WiMAX Typically, fixed WiMAX networks have a higher-gain directional antenna installed near the client (customer) which results in greatly increased range and throughput

TYPES… : 

TYPES… Mobile WiMAX networks are usually made of indoor "customer premises equipment" (CPE) such as desktop modems, laptops with integrated Mobile WiMAX or other Mobile WiMAX devices. Mobile WiMAX devices typically have an omni-directional antenna which is of lower-gain compared to directional antennas but are more portable

MODES OF OPERATION : 

MODES OF OPERATION LINE OF SIGHT Uses a lower frequency range.

MODES OF OPERATION : 

MODES OF OPERATION NON LINE Of SIGHT Uses a higher frequency range

ADVANTAGES : 

ADVANTAGES Wimax Coverage Wimax High Speed Multi-functionality within Wimax Technology Potential and development Wimax Infrastructure Wimax, cheap network Wimax Rich Features Smart antenna and Mesh Topology Ultra wide Band Homeland Security

disadvantages : 

disadvantages Lack of Quality Wimax range Wimax Bandwidth Expensive network Bad Weather Wireless equipments Power consuming

FEATURES OF WIMAX : 

FEATURES OF WIMAX Scalability Quality of Service The 802.16 standard supports flexible radio frequency (RF) channel bandwidths. The standard supports hundreds or even thousands of users within one RF channel As the number of subscribers grow the spectrum can be reallocated with process of sectoring. Primary purpose of QoS feature is to define transmission ordering and scheduling on the air interface These features often need to work in conjunction with mechanisms beyond the air interface in order to provide end to end QoS or to police the behaviour or SS.

FEATURES OF WIMAX : 

FEATURES OF WIMAX RANGE Coverage Optimized for up to 50 Km Designed to handle many users spread out over kilometres Designed to tolerate greater multi-path delay spread (signal reflections) up to 10.0μ seconds Standard supports mesh network topology Optimized for outdoor NLOS performance Standard supports advanced antenna techniques

FUTURE : 

FUTURE WiMax will be deployed in three stages In the first phase WiMax technology (based on IEEE 802.16-2004) provides fixed wireless connections In the second phase WiMax will be available as a cheap and self-installing Subscriber Terminal (ST), linked to PC and to antenna The third phase enables portability, thus WiMAX (based on IEEE 802.16e) will be integrated into commercial laptops

Conclusion : 

Conclusion It is highly unlikely that WiMAX will compete with or replace every other wireless technology; however, WiMAX will fulfill a very valuable role in the wireless ecosystem. By providing and overview of the fundamental WiMAX business models, as well as market and technological challenges, we have attempted to illustrate the implications of creating and capturing value through WiMAX. By outlining market players and the competitive nature of the WiMAX market, we have attempted to provide a glimpse of what the WiMAX landscape may resemble in the not so distant future.
