Introduction To WiMAX. How does it works. Connecting to wimax. Technical details. Uses Of WiMAX. Comparison Of Latest Wireless Technologies.Slide 4: Ways T o Connect T o Internet 1. Dial-up access Problem – very low data transfer rates. 2. Wi-Fi access Problem – hot spots are small, so coverage is sparse. 3. Broadband access Problem – Doesn’t reach all areas.Slide 5: “ A New Technology !! ” High speed of broadband service Wireless rather than wired access Much easier to extend to rural areas Broad coverage like cell phone networks. This technology is known as WiMAXSlide 6: What is Wimax WIMAX is a wireless digital communication system also known as IEEE 802.16. It gives an alternate to cable and DSL. It can provide broadband wireless access up to 30 miles(50 km) for fixed stations and up to10 miles(16 km) for mobile stations. The current WiMAX revision provides up to 40 Mbps with the IEEE 802.16m update expected to offer up to 1 Gbps fixed speeds.Slide 7: WIMAX operates similar to WIFI but at higher speeds, over greater distances and for greater number of users. A wimax system has two parts :- 1. A WiMAX tower , similar in concept to a cell-phone tower. 2. A WiMAX receiver - The receiver and antenna could be a small box or PCMCIA card, or they could be built into a laptop the way WiFi access is today. Working of WiMAXSlide 8: A WiMAX tower station can connect - directly to the Internet using a high-bandwidth, wired connection - to another WiMAX tower using a line-of-sight, microwave link. Two types of wireless service are provided by wimax :- 1. Line of sight – higher frequency (10-66 GHz) 2. Non-line of sight – lower frequency (2-11 GHz) Working of WiMAX Continued...Slide 9: Subscriber units are available in the market that can be used to connect to wimax. Mobile Handsets PC peripherals (PC cards or USB dongles) Embedded in Laptops Gateways Both indoor and outdoor versions are available. Connecting to WiMAXSlide 10: The IEEE 802.16 standard - the original version of the wimax was based on IEEE 802.16-2004 - the current version uses the IEEE 802.16e-2005, approved in 2005. Physical layer - Original – 10-66 GH z - Current – 2-11 GHz - The current version uses SOFDMA as opposed to OFDM used by the original version. Technical DetailsSlide 11: MAC (data link) layer - The subscriber needs to compete only once - The time slot can enlarge or contract but will remain assigned to the subscriber station Spectrum allocation - No uniform global licensed spectrum for WiMAX. - WiMAX Forum has published three licensed spectrum profiles: 2.3 GHz, 2.5 GHz and 3.5 GHz. Technical Details Continued...Slide 12: Can be used as a backhaul for other networks. WiMAX supports the technologies that make triple-play service offerings possible. Rapid deployment helps to assist communications. Uses Of WiMAXSecurity: Security X.509 certificate AES DES 3Disadvantages of WiMAX: Disadvantages of WiMAX Line of sight is needed for distant connections. Bad weather conditions like rain can interrupt the signals. Wimax is a very power consuming technology and required significant electrical support. High installation and operational cost.Slide 15: ComparisonSlide 16: Questions ?? Got I’ve got the Answers. You do not have the permission to view this presentation.
