Wi max by yogijicreations
WiMAX is a wireless technology that provides broadband access over long distances. It can deliver high-speed internet access to both fixed and mobile users. WiMAX uses radio signals to transmit data between an antenna mounted on a structure like a tower and a wireless device. This allows it to provide broadband connectivity to areas where cable or DSL internet is unavailable or too expensive. WiMAX has advantages over WiFi like greater range, higher speeds, and less interference. While it promises high speeds and long ranges, its real-world performance depends on factors like line of sight, number of users, and environmental conditions. WiMAX can help provide emergency communications networks that are difficult to disrupt.
Wimax and lte
3G networks faced issues accommodating mobile internet demand, including high costs of expanding networks. Performance was also low in densely populated and dead spot areas. IMT-Advanced networks were developed to address these issues by providing higher data rates, better mobility support, improved indoor coverage, and more compatible international roaming compared to 3G networks. WiMAX is a telecommunications technology that can provide wireless broadband internet over wide areas as an alternative to DSL and cable. It uses the IEEE 802.16 standard and can transmit data at distances of up to 30 miles.
Wi fi technology
WiMAX is a wireless communication technology that provides broadband internet access over long distances, surpassing the range of Wi-Fi. It uses IEEE 802.16 standards for wireless data transfer and can deliver speeds up to 1 Gbit/s for fixed locations and 75 Mbit/s for mobile use. WiMAX is used for internet access, mobile backhaul, and triple play services. It connects using various devices like indoor/outdoor gateways, external modems, and mobile phones that are certified by the WiMAX Forum to ensure interoperability.

WiMAX is a wireless technology that provides broadband connectivity over long distances, allowing users to connect to the internet without being near a WiFi hotspot. It operates using radio signals in a similar way to WiFi but can transmit data over distances of up to 30 miles for fixed points or 3-10 miles for mobile users. WiMAX supports both line-of-sight and non-line-of-sight connections and can deliver speeds comparable to cable internet, making it a viable option for broadband access in both urban and rural areas.
WI-FI and Wi Max
Wi-Fi and WiMAX are wireless networking technologies. Wi-Fi uses radio waves to connect devices in local areas like homes and offices, while WiMAX can connect devices over longer distances of up to 30 miles, making it suitable for connecting entire cities. Both technologies transmit data using radio signals in specific frequency ranges and support various transmission speeds and encryption standards. Wi-Fi devices connect directly to a local wireless router or access point, while WiMAX uses wireless towers similar to cellular networks to connect multiple users over wider areas.

It then addresses whether WiMAX will replace these existing broadband technologies. While WiMAX provides broadband wireless access not available in all areas, DSL and cable will likely continue to be deployed where infrastructure allows. The document goes on to describe the IEEE 802.16 standard that defines WiMAX and how it has evolved. It also explains WiMAX system models including point-to-point, point-to-multipoint, and mesh topologies. Finally, it covers WiMAX's use as a metro-access option and details its physical layer technology which is based
WiMAX presentation v2
WiMAX is a wireless technology that provides broadband connections over large areas using towers similar to cell phone towers. Towers can provide coverage up to 3000 square miles and connect to the internet or other towers using line-of-sight microwave links between 10-66 GHz. Within a 4-6 mile radius of each tower, WiMAX receivers in devices like laptops can get wireless access at speeds up to 70 Mbps. By the end of 2010, WiMAX was projected to be available in over 80 US cities.
EMERGING BROADBAND WIRELESS TECHNOLOGIES: WIFI AND WIMAX
Now-a-days there is high demand for broadband mobile services. Traditional high-speed
broadband solutions depend on wired technologies namely digital subscriber line (DSL). Wifi
and Wimax are useful in providing any type of connectivity such as the fixed or portable or
nomadic connectivity without the requirement of LoS (Line of Sight) of the base station. Mobile
Broadband Wireless Network (MBWN) is a flexible and economical solution for remote areas
where wired technology and also terminal mobility cannot be provided. The IEEE Wi-Fi and
Wi-Max/802.16 are the most promising technologies for broadband wireless metropolitan area networks (WMANs) and these are capable of providing high throughput even on long distances with varied QoS. These technologies ensure a wireless network that enables high speed Internet access to residential, small and medium business customers, as well as Internet access for WiFi hot spots and cellular base stations. These offer support to both point-to-multipoint (P2MP) and multipoint-to-multipoint (mesh) nodes and offers high speed data (voice, video) service to the customers. In this paper, we study the issues related to, benefits and deployment of these technologies.

Wimax
- 1. Presented by Naveed Ahmad UET Peshawar
- 2. “WiMAX-we believe it’s the next big thing in the wireless broadband arena”
- 5. INTRODUCTION: WiMAX(Worldwide Interoperability For Microwave Access) is a wireless communications standard designed to provide 30 to 40 megabit-per-second data rate. A fourth generation (4G) technology WiMAX is technically also known as “IEEE 802.16” WiMAX is a wireless communications standard designed for creating Metropolitan Area Networks(MANs).
- 6. 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 WiMAX system consist of: 1) 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).
- 7. 2) 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 Wi-Fi access is today
- 8. MODES OF OPERATION Non-line-of-sight Wi-Fi sort of service A small antenna on your computer connects to the tower. WiMAX uses a lower frequency range -- 2 GHz to 11 GHz (similar to Wi-Fi).
- 9. A fixed dish antenna points straight at the WiMAX tower from a rooftop or pole. The line-of-sight connection is stronger and more stable, so it's able to send a lot of data with fewer errors It use higher frequencies, with ranges reaching a possible 66 GHz. At higher frequencies, there is less interference and lots more bandwidth Line-of-sight
- 11. A WiMAX tower station can connect directly to the internet using a high-bandwidth, wired connection. How It Works? It can also connect to another WiMAX tower using a line-of-sight, microwave link. This connection to a second tower (often referred to as a backhaul), along with the ability of a single tower to cover up to 3,000 square miles It allows WiMAX to provide coverage to remote rural areas
- 13. Connectivity Devices that provide connectivity to a WiMAX network are known as the “subscriber stations”. Some of the portable units are: Mobile Phones PC peripherals Laptops Gaming consoles MP3 Players
- 14. FEATURES OF WIMAX Frequency bands - 2 to 11 GHz and 10 to 66 GHz (licensed and unlicensed bands) Range – 30 mile (50-km) radius from base station Speed - 70 megabits per second Coverage-A single tower covers upto 3000 sq.miles so remote areas can easily get broadband access
- 16. Applications According to WiMAX forum, it supports five classes of applications: Multi-player Interactive Gaming. VOIP and Video Conference Streaming Media Web Browsing and Instant Messaging
- 17. Present research work on WiMAX WiMAX2 is the present ongoing development in the WiMAX versions. That is to increase the speed of existing WiMAX network. Currently existing WiMAX versions provides minimum of 30 to 40 megabits per second of speed. But the goal of the WiMAX2 is to get 100 Mbit/s for mobile devices and 1 Giga bits per second fixed type of WiMAX devices and 4G for next generation mobile network
- 19. Thank You!!!!
