4G Broadband

The early days of home Internet access required using a modem connected to a computer to dial a number and maintain a connection. It was cumbersome and slow. The faster modems became, the more people realized how painfully sluggish data transmission had been in the days of 300 baud. Eventually, home users who could afford a jump in price could get Broadband access via digital subscriber lines (DSL), cable and satellite. Technology changes from day-to-day; this is also happening in case of networking. So many breakthroughs in the realm of science forced the way of networking from wired to wireless, which is very inexpensive and efficient. A new technology that provides dynamic connectivity to a network through wireless which is called as Wi-Fi (Wireless Fidelity), works on the principle of Radio transmission, but Wi-Fi is accessible only to a limited area, In this paper we are going to present about a technology which breaks the problems like limited area connectivity and also ECO Friendly, this can be possible with the help of WiMax(Worldwide Interoperability for Microwave Access), which supports the concept of Internet everywhere. However people are connected by opening up the Internet to create a more spontaneous and empowering broadband experience.


If we have been in an airport, coffee shop, library or hotel recently, chances that we been right in the middle of a wireless network. Many people also use wireless networking, also called Wi-Fi or 802.11 networking. In the near future, wireless networking may become so widespread that you can access the Internet just about anywhere at any time, without using wires, wireless networks are easy to set up and inexpensive.
Wireless network uses radio waves, just like cell phones, televisions and radios do. In fact, communication across a wireless network is a lot like two-way radio communication
1. A computer's wireless adapter translates data into a radio signal and transmits it using an antenna.
2. A wireless router receives the signal and decodes it. It sends the information to the Internet using a physical, wired Ethernet connection.
The process also works in reverse, with the router receiving information from the Internet, translating it into a radio signal and sending it to the computer's wireless adapter

Need for WiMax
WiMAX outdistances Wi-Fi by miles, WiMAX is short for Worldwide Interoperability for Microwave Access, and it also goes by the IEEE name 802.16, WiMAX would receive data from the WiMAX transmitting station, probably using encrypted data keys to prevent unauthorized users from stealing access this is the main advantage. In this way network security is also embedded.
WiMAX has the potential to do to broadband Internet access what cell phones have done to phone access. In the same way that many people have given up their "land lines" in favor of cell phones, WiMAX could replace cable and DSL services, providing universal Internet access just about anywhere you go. WiMAX will also be as painless as Wi-Fi -- turning your computer on will automatically connect you to the closest available WiMAX antenna
A WiMAX tower station can connect directly to the Internet using a high-bandwidth, wired connection (for example, a T3 line). 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, is what allows WiMAX to provide coverage to remote rural areas.
Wi-Fi-style access will be limited to a 4-to-6 mile radius (perhaps 25 square miles or 65 square km of coverage, which is similar in range to a cell-phone zone). Through the stronger line-of-sight antennas, the WiMAX transmitting station would send data to WiMAX-enabled computers or routers set up within the transmitter's 30-mile radius (2,800 square miles or 9,300 square km of coverage). This is what allows WiMAX to achieve its maximum range

Internet service provider sets up a WiMAX base station 10 miles from our home. we would buy a WiMAX-enabled computer or upgrade our old computer to add WiMAX capability. we would receive a special encryption code that would give you access to the base station. The base station would beam data from the Internet to our computer (at speeds potentially higher than today's cable modems), for which we would pay the provider a monthly fee. The cost for this service could be much lower than current high-speed Internet-subscription fees because the provider never had to run cables. The WiMAX protocol is designed to accommodate several different methods of data transmission, one of which is Voice Over Internet Protocol (VoIP). VoIP allows people to make local, long-distance and even international calls through a broadband Internet connection, bypassing phone companies entirely. If WiMAX-compatible computers become very common, the use of VoIP could increase dramatically. Almost anyone with a laptop could make VoIP calls.
XOHM (4G Technology):
XOHM is coming – providing next-generation mobile broadband across your city. With XOHM, you no longer need to find a hotspot for a broadband internet experience – the hotspot comes with you. There are no compromises here – even if it’s streaming fullscreen video. And with XOHM, you have one account and it’s always available. No long-term contracts – you can pay by the day, the month or the year
XOHM won’t just connect WiMAX-enabled products to the internet it’ll allow them to connect across the network to each other. We expect this to open exciting new experiences beyond just getting online with the potential to change how we communicate, enjoy, and achieve - for example:
• Health: a mobile health monitor could track and transmit a user’s vitals and alert a hospital or caregiver in case of an emergency.
• Sports: a runner’s performance could be monitored by WiMAX-enabled chips built into her shoes to be shared with coaches, peers or spectators.
• Home Entertainment: While you’re out of town, your WiMAX-enabled DVR could send a reminder to your phone that your favorite TV show is about to start - command it to record the show to watch later via your WiMAX-enabled portable video player 

4G Broadband

Next Generation Internet
Get ready to experience how spontaneous the internet can be. With XOHM mobile broadband, you’ll be able to:
 Stream movies
 Watch a video
 Download music
 Share photos
 Play games
 Instant Message
 E-mail
 Surf the web
Or whatever you want - around your home, office or on the go, wherever there’s XOHM coverage - all on the same connection
Plug and Play:
Getting started with XOHM is a snap: no wires means no service calls, drilling, or digging – just plug and play.
Compendium:
It is to be concluded that among all communication interfaces wireless is better one, in that going to WiMax is the better solution in all aspects, now some of the companies are trying to establish their networks using this technolog
