Presented & performed by : Ankit Aggarwal Electronics Engineering INDIA Contents : Contents Introduction Certification Advantages -Uses Piggybacking Topologies triple play Comparisions Conclusion -Video Slide 3: Means Wi-Fi : Wireless Fidelity * A Local Area Network that uses high frequency radio signals. * Uses Ethernet protocol (means "a network of everywhere.“) * The term Wi-Fi, first used commercially in August 1999. * Belanger created the yin-yang-style Wi-Fi logo. Slide 4: A radio technology that networks the devices. Refers to wireless LAN products based on the IEEE 802.11b specification Provides easy connections to the internet and business networks while traveling The main attractive feature of this technology is that it can provide wireless broadband connection within a specific geographic boundary. Wireless Fidelity (Wi-Fi)Welcome to the World of Wireless Slide 5: Wi-Fi certification Wi-Fi technology builds on IEEE 802.11 standards The right to mark products with the Wi-Fi logo. Tests includes of IEEE 802.11 draft standards : # Security set-up # Multimedia # power-saving. Institute of Electrical and Electronics Engineers 802.11a/b/g (Wi-Fi) : IEEE 802.11 Is A set of standards. Created & maintained By IEEE. 802.11a/b/g (Wi-Fi) 802.11n – 100Mbps, still in draft Slide 7: ADVANTAGES & CHALLENGES…! Operational Advantages Reach Mobility Data Security Risks Internet access : USES City-wide Wi-Fi Direct PC-to-PC communication Internet access Campus-wide Wi-Fi Slide 9: Internet Access # Connect to the Internet # Wi-Fi can provide public access. City & Campus-wide Wi-Fi # Sunnyvale, California first city -wide free Wi-Fi. # Drexel University in Philadelphia first university campus in 2000. Direct Pc to PC communication # ad-hoc mode of Wi-Fi transmission. # multiplayer,game consoles, digital cameras, electronics devices. USES Hardware (Standard devices) : Hardware (Standard devices) Slide 11: Piggybacking refers to access to a wireless Internet connection by bringing one's own computer within the range of another's wireless connection, and using that service without the subscriber's explicit permission or knowledge. Piggybacking Topology of a Wireless Network : 12 Topology of a Wireless Network Point-to-point Point-to-multipoint Mesh Smart Antenna Arrays Topology of a Wireless Network : 13 Topology of a Wireless Network Point-to-point Usually very high speed and high capacity Requires a clear line of sight to tower Backbone, or backhaul connectivity Corporate/Business Class service Topology of a Wireless Network : 14 Topology of a Wireless Network Point-to-multipoint Similar technology to point-to-point network Topology of a Wireless Network : 15 Topology of a Wireless Network Mesh Network Distributed gateway devices Self healing network Uses multiple radios in tight formation “Micro cell” concept Relatively easy to deploy Topology of a Wireless Network : 16 Topology of a Wireless Network Smart Antenna Arrays High powered & directional Switched Array of multiple access points Better obstruction penetration, but still limited Good for covering large open, or semi-open environments Coverage from high vantage points usually works best Wi Max stands for Worldwide Interoperability for Microwave Access : Wi Max stands for Worldwide Interoperability for Microwave Access It is built on IEEE 802.16 standards It is a Wireless Technology that provides high throughput broadband connections over long distances. Wi Max is both faster and has a longer range than Wi-Fi. It represents the next generation of wireless Slide 18: Technical Details:- Range 30 mile radius from base station. Speed 70 Megabits per second. Line of sight not needed between user and base station. Frequency bands- 2 to 11 GHz & 10 to 66 GHz Slide 19: Wi Max operates similar to Wi-Fi but at high speeds, over long distances and for a greater number of users. A Wi Max consists of two parts A Wi Max tower, provides coverage to a very large area. A Wi Max receiver and antenna could be a small box. Wi Max Transmitting Tower Working of Wi Max IEEE 802.16 -- Introduction : IEEE 802.16 -- Introduction Source: WiMAX, making ubiquitous high-speed data services a reality, White Paper, Alcatel. IEEE 802.16 -- Introduction : IEEE 802.16 -- Introduction Coverage range up to 50km and speeds up to 70Mbps(shared among users). Slide 22: The bandwidth and range of WiMAX & relatively low cost to deploy a WiMAX network (in comparison to GSM, DSL orFiber-Optic), it’s now possible places where it might have been previously economically unviable. Uses • Providing portable mobile broadband connectivity across cities and countries through a variety of devices. • Providing a wireless alternative to cable and DSL for "last mile" broadband access. • Providing data, telecommunications (VoIP) and IPTV services (triple play). ??? Devices. ??? Triple play… Slide 23: WiMAX supports the technologies that make triple-play service offerings possible (such as Quality of Service and Multicasting). Triple-play Slide 24: This includes handsets (similar to cellular smartphones); PC peripherals (PC Cards or USB dongles); and embedded devices in laptops. Gaming consoles, MP3 players and similar devices. DEVICES…!! Slide 25: There are two versions: Indoor SU. Outdoor SU. Indoor units are comparable in size to a cable modem or DSL modem. Outdoor units are roughly the size of a laptop PC, and their installation is comparable to a residential satellite dish. There is an increasing focus on portable units including handsets and PC peripherals. Outdoor subscriber unit Indoor subscriber unit Subscriber units The First Wi Max Chip Slide 26: Wi-Fi 802.11 WiMax 802.16a Speed 6 - 54 Mbps 70 Mbps Coverage 30 m 50 km The biggest difference isn't speed, it's distance. Wi Max out distances Wi-Fi by miles. Comparison between Wi-Fi & Wi-Max: Slide 27: WiMAX, LTE, MESHWireless Network Doctors at the emergency room can see the vehicle and get an understanding of the mechanism of injury to guide their treatment of the victim. Portable or fixed mounted cameras can be used to capture video or still images of a vehicle accident to send to emergency room doctors. Enables real time monitoring of Patients on the way to the Hospitals Vehicle accident Slide 28: WiMAX, LTE, MESH Wireless Network Doctors at the emergency room can help guide treatment of the victim, especially important for time critical treatment. Cameras inside ambulances can capture video of patients to send to emergency room doctors for consultation. Remote diagnosis can shorten the time before treatment which can potentially save lives and shorten recovery time Remote medical diagnosis Slide 29: Thank You very much…..
