The Work Of Wireless Internet

The advantage of wireless internet

Wireless internet has many advantages both for business and residential users. Provide broadband-speed wireless Internet is very good. Today, at over 2 Mbps for commercial use (megabytes per second) obtained using the wireless Internet.

Previously up to 1 Mbps speeds are acceptable for wireless internet, but with content providers who provide speed at 8 Kbps and up to business and residential customers through cable (fiber optic), wireless internet expectations running too high. This could mean only one thing-speed wireless internet sooner or later it will catch up with the speed offered through fiber optic cable.

Wireless Internet is more reliable than the Internet through a cable or satellite. Initial cost to the service provider will also be reduced because they do not have to spend paying expensive cable or satellite transmissions are for. All that is needed is to establish internet tower (very similar to the cellular tower). Users will be connected to the internet for his laptop / device is receiving signals from the nearest tower (once again, very similar to using a mobile phone).


Comparison between the cellular networks work and the wireless Internet network can be made to a certain extent, but working from a wireless Internet network is much more complex in nature. So, how wireless Internet works?

How WiMAX works
We can single out WiMAX (Worldwide Interoperability for Microwave Access) technology is widely used for setting up wireless internet. High speed can be achieved through a wireless network using this technology. Based on the IEEE 802.16 communications standard, this technology fast replacing complicated if cable and satellite networks expensive.

WiMax network consisting of base stations (similar to cellular tower) is set by the service provider, and a receiver antenna (similar to mobile phone antenna) at the user end. Users pay for the service provider wireless internet access, just as they would for a normal internet connection via cable networks. The service provider will provide end users with software, a login and password. Most manufacturers today complements the high-end laptop models with built in antenna is bundled with the software needed to be WiMax compatible units. Internet service providers semaphore from the base station. Antenna at the user end to catch the signal, which provides for uninterrupted internet signal is available. With a laptop equipped with an antenna you can connect to the Internet wherever a signal is available from the base station. As with cellular phone signals from nearby towers from certain service providers, as well as a new generation of WiMax services. One WiMAX base station can send signals over distances several miles depending on terrain. The flatter the terrain, more coverage. Once you move from one base station to another, the recipient will connect your laptop to another base station (from the same service provider) with a stronger signal. For WiMAX service providers to spread their operations, everyone will connect with truly high speed internet 24x7 wherever they are.

Another common use of wireless internet
Wireless Internet is not limited to WiMax. Most of us have used a wireless internet some time or another. GPRS (General Packet Radio Service) is one example. When a mobile user subscribed to a GPRS service, the recipient mobile unit can receive voice and data signals. Simply put, mobile phones can be used as a phone for voice calls and also as a modem to connect to a computer to surf the internet. The only limiting factor here is a very slow pace. This technology was gradually replaced by EDGE (Enhanced Data Rates for Global Evolution) technology. EDGE is an enhancement over GPRS, able to provide greater capacity for voice traffic and at the same time have a high speed data transfer capabilities.

EDGE technology has recently been replaced by 3G (Third Generation) technology. Speeds of 2Mbps is achieved by using 3G technology. This speed will continue to increase with technological advances. 4G (Fourth Generation) will be the next major change in this domain. 4G research is being done, but nothing that has not been allocated frequencies for this technology. It is estimated that 4G will be around 2010-2012, but with the speed of technological advance, it could happen earlier.

Conclusion
Mobile phones that have passed the stage where they used to just make and receive calls. Now people can buy a mobile phone to do almost anything that your personal computer or laptop can be. The operating system can be loaded into the phone, almost making them a tool for all your phone and computing needs. This is where the wireless Internet will play an important role in the future. This will connect you 24x7 with almost no damage.

Cable still be used for the Internet to wireless internet time to adjust the speed of data transfer cable. Once this happens, technologies such as WiMax and 3G will help in making this world a 24x7 connected, wire-free world./source : http://d3nba9uzs.blogspot.com

Hi.. please advice how to gain the signal from a WAP via antenna

Free Your Mind said...

I think WiMax in the future will have wider area of internetworking than GPRS did
