Wi-Fi allows wireless networking connectivity within homes and offices without wires, using radio signals to connect devices within 100 feet of each other. WiMAX provides broader wireless coverage over distances of up to 50km to serve as a wireless alternative to wired broadband. While Wi-Fi is best for small indoor coverage areas, WiMAX is designed for larger outdoor metropolitan coverage as a wireless option for last mile internet access to homes and businesses. Both technologies will continue to evolve and work together, with WiMAX complementing Wi-Fi for broader range wireless connectivity and Intel integrating their capabilities into single chips.

And even though the specification has been ratified for some time now, 802.11n hardware continues to evolve.
Join us as we explore the number of MIMO streams, channel bonding, guard interval lengths, and other characteristics that define your WLAN capabilities. We’ll also characterize the current state of commercially available 802.11n hardware, arming you with the information you need to determine if, when, and how you want to make the move.
In these slides, we will cover:
- Key technologies that are new to 802.11n
- The relative importance of each technology in contributing to increased performance
- The current “state of the art” of commercially available 11n equipment
What you will learn:
- What new 11n technologies are most important to you

By switching LED bulbs on and off faster than the human eye can detect, digital data can be encoded and transmitted through the light. Li-Fi provides several advantages over traditional Wi-Fi including much higher speeds, no interference with other wireless devices, and the ability to be used in places where radio signals are restricted. Researchers have achieved speeds over 500 megabytes per second in labs. Li-Fi has the potential to help solve the worldwide shortage of wireless spectrum and enable new applications for wireless connectivity through light.
Gi fi seminar Report
Gi-Fi is a new wireless technology that offers faster data transfer rates than Wi-Fi and WiMax. It uses 60GHz frequency and can transfer data at rates up to 5 gigabits per second, which is 10 times faster than current wireless technologies. Gi-Fi uses an integrated transceiver chip developed in Australia that operates at low power. It allows quick transfer of large files like videos within seconds over short ranges. Gi-Fi is expected to become the dominant wireless technology for applications like wireless home networks and high-speed transfer between devices.

Wi fi and wi-Max
- 1. WI-FI / WI-MAX ANKIT GUPTA MCA 3rd year 1003714008
- 2. WI-FI / WIMAX WI-FI access is hot spots that are very small, so coverage is sparse. WI-Max access is a high speed of Broadband and is wireless instead of wired.
- 3. WI-FI Wi-Fi is the wireless way to handle networking. It is also known as 802.11 networking. The big advantage of Wi-Fi is its simplicity. You can connect computers anywhere in your home or office without the need for wires. The computers connect to the network using radio signals, and computers can be up to 100 feet or so apart.
- 4. WIRELESS NETWORKING STANDARDS Wi-Fi refers to the protocols that allow wireless networking. These protocols are codified in standards. Standards are mutually agreed upon rules adopted by the industry on how the wireless networks operate.
- 5. WI-FI TYPE Wireless Personal Area Networks - Up to 10 meter - IEEE 802.15.1 (Bluetooth) Wireless Local Area Networks - Up to 100 meter - IEEE 802.11 (Wi-Fi)
- 6. GOVERNING STANDARDS BODY Formed in 1999 Founding Companies: 3Com Aironet Harris Semi Conductor Lucent Symbol Technologies Nokia
- 7. SPECIFICATIONS 802.11a 802.11b 802.11g 802.11n
- 8. WLAN ARCHITECTURE—AD HOC MODE Ad-Hoc mode: Peer-to-peer setup where clients can connect to each other directly. Generally not used for business networks.
- 9. APPLICATION OF WI-FI Many electronic devices use Wi- Fi due to its simple functions. Companies use Wi-Fi to create wireless networks within their company. Phone companies such as use Wi-Fi Hot Spots for their users to get free calling/internet access. Gaming companies like Nintendo use Wi-Fi to synch their products and to use global network usage.
- 10. WI-FI SECURITY 64-bit encryption - original 128-bit encryption - much secure
- 11. FUTURE OF WIRELESS TECHNOLOGY The future is WI-Max Can reach over 50km in range and have a maximum throughput of 70 Mbps.
- 12. WIMAX Worldwide Interoperability for Microwave Access Brand licensed by the WiMax Forum. “a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL” WiMAX was seen as more of a Metropolitan Area Network (MAN) technology providing a much larger coverage. Based on IEEE 802.16
- 13. WIMAX Goal: Provide high-speed Internet access to home and business subscribers, without wires. Base stations (BS) and subscriber stations (SS) Centralized access control to prevents collisions Supports applications with different QoS requirements WiMAX is a subset of IEEE 802.16 standard
- 14. WI MAX WiMAX, in fact, comes in two forms, one is called ‘fixed WiMAX’ and another is ‘mobile WiMAX’. WiMAX in its fixed form is seen as a possible alternative to expensive cable and fibre deployment. It is faster to deploy and less expensive and it also offers operators more flexibility in terms of deployment time frame and possible installation areas. 3G or other cellular network operators could see this as a potential substitute or as a complement to their cellular product.
- 15. WI MAX KEY FEATURE Modulation technique Operating frequencies Problems in wireless transmission
- 16. WIFI VS. WIMAX IEEE 802.11 (Wi-Fi) IEEE 802.16a (WI Max) Max Speed 54Mbps (a&g) 10-100Mbps Range 100m 40 km QoS none yes Coverage Indoor Outdoor Users Hundred Thousand Service Level None Yes
- 17. CONTINUED..
- 18. WILL WIMAX DISPLACE WIFI? WiMAX will not replace WiFi completely, but work TOGETHER Intel is currently integrating WiMAX and WiFi into a single Centrino chip. WiFi’s primary role will always be autonomous hotspot service areas (indoor and outdoor 0 ft. < cell radii <500 ft.). WiMax will ultimately replace WiFi in large-scale (greater than 1mi.Sq.) commercial and public roles.
- 19. WI-FI AND WIMAX TOGETHER
