Note : Currently Using Wateen to give costumers wimax services in Pakistan



•Worldwide Interoperability for Microwave Access (WiMAX)
•emerging wireless technology
•ensures compatibility and interoperability between broadband wireless access equipment
•range of up to 31 miles.
•primarily aimed at making broadband network access widely available.
•Overcome distance limitations of Digital Subscriber Line.


A WIMAX system

•A WiMAX tower, similar in concept to a cell-phone tower - A single WiMAX tower can provide coverage to a very large area as big as 3,000 square miles (~8,000 square km).
•A WiMAX receiver - The receiver and antenna could be a small box or Personal Computer Memory card, or they could be built into a laptop the way WiFi access is today

FEATURES OF WIMAX

•Scalability

•Quality of Service

•Range

•Coverage

RANGE


•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

BENEFITS OF WIMAX

•Speed
• Faster than broadband service
•Wireless
•Not having to lay cables reduces cost
•Easier to extend to suburban and rural areas
•Broad Coverage
•Much wider coverage than WiFi hotspots

Benefits to Customers

•Range of technology and service level choices from both fixed and wireless broadband operators
•DSL-like services at DSL prices but with portability
•Rapidly declining fixed broadband prices
•No more DSL “installation” fees from incumbent

Advantages of WiMax over 3G

•Using an assortment of proprietary and standards-based technologies, such as OFDM and W-CDMA ,WiMax has a clear advantage over 3G
•The advantages include
•Higher Throughput
•Low Cost
•Lower Latency

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
