Advantages of wireless internet
Wireless internet has many advantages for both the business as well as residential users. Wireless internet provides excellent broadband speeds. Today speeds of over 2 Mbps for commercial use (megabytes per second) are attained using wireless internet.

Previously speeds of up to 1 Mbps were acceptable for wireless internet, but with service providers providing speeds of 8 Kbps and above to business and residential customers through cables (fiber optic), expectations through wireless internet too are running high. This could mean just one thing -speeds through wireless internet will sooner or later catch up with speeds offered through fiber optic cables.

Wireless internet is more reliable as compared to internet via cable or satellite. Initial costs to the service provider too are reduced as they do not have to lay out expensive cables or pay highly for satellite transmission. All that is required is the setting up of internet towers (very similar to mobile towers). The user will be connected to the internet as long as his laptop / device receives a signal from the nearest tower (again, very similar to using a mobile phone).

Comparisons between the workings of a mobile network and wireless internet network can be made to some extent, but the working of a wireless internet network is much more complex in nature. So, how does the wireless internet work?

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

The WiMax network consists of base stations (similar to mobile towers) set up by the service provider, and a receiving antenna (similar to a mobile phone antenna) at the user end. The user pays the service provider for wireless internet access, just as they would for a normal internet connection via a cable network. The service provider provides the end user with the software, a login and a password. Most of the laptop manufacturers today equip high-end models with a built in antenna bundled with the required software for the unit to be WiMax compatible. The service provider beams the internet signals from the base station. The antenna at the user end catch the signals, providing uninterrupted internet as long as the signal is available. With a laptop equipped with an antenna you could be connected to the internet wherever the signal is available from the base station. As with mobile phones that catch a signal from the nearest tower of the particular service provider, so is it with new generation WiMax services. One WiMax base station can send signals over distances of several miles depending on the terrain. The more flat the terrain, more the coverage. Once you move from one base station area to another, your laptop receiver will hook up to the other base station (of the same service provider) with a stronger signal. As WiMax service providers spread out their operations, everyone will be connected to really high-speed internet 24X7 wherever they are.

Other common uses of wireless internet
Wireless internet is not limited to WiMax. Most of us have used some sort of wireless internet some time or the other. GPRS (General Packet Radio Service) is one such example. When a mobile user subscribed to the GPRS service, the receiving mobile unit could receive voice as well as data signals. In simple terms, the mobile phone could be used as a phone for voice calls and also as a modem to connect to the computer to surf the internet. The only limiting factor here was the speed which was very slow. This technology was gradually replaced by the EDGE (Enhanced Data Rates for Global Evolution) technology. EDGE was an enhancement over GPRS, able to provide more capacity for voice traffic and at the same time have high-speed data transfer capabilities.

EDGE technology has recently been replaced by the 3G (Third Generation) technology. Speeds of over 2Mbps are attained using 3G technology. These speeds will keep on increasing with advancing technology. 4G (Forth Generation) will be the next main change in this domain. 4G research is being carried out, but no frequencies have yet been allocated for this technology. Estimates are that 4G will be implemented around 2010-2012, but with the speed at which technology is advancing, it could happen earlier.

Conclusion
Mobile phones have passed the stage where they were used to just make and receive calls. Today one can buy mobile phones that do almost everything that your personal computer or laptop can. Operating systems can be loaded onto mobiles, virtually making them one instrument for all your phone and computing needs. This is where wireless internet will play a major role in the future. It will connect you 24X7 with virtually no breakdowns.

Cables will still be used for the internet till the time wireless internet can match data transfer speeds of cables. Once this happens, technologies such as WiMax and 3G will help in making this world a 24X7 connected, wire-free world.

With over half the population in most countries being affected by obesity, it has become vital to find a solution for it. In this context, Calotren supplement has been found to be of great use. It is a protein supplement which helps the body to lose fat in a natural way. It works in combination with a healthy diet and regular exercise pattern and works slowly to show its effects. But what are the pros and cons of taking Calotren? We must find out all about the supplement before deciding to take it regularly.

Burning Up The Calories

Calotren is mainly made up of collagen hydrolysate, which is a form of protein. This protein is very essential in building lean muscle mass which is found in the muscles, organs and joint tissues. In the process of developing these muscles, collagen is produced. The more the collagen, the more the lean muscle mass. And this lean muscle mass again burns up more calories, leading to weight loss. Calotren serves as a supplier of collagen to the body. Therefore, it aids in the development of lean muscle mass and consequently in losing weight. The lean muscle mass burns up more calories than other parts of the body. As more calories are burnt, more fat is destroyed which leads to a leaner body.

What About The Side-Effects?

Calotren supplement has zero side effects. This has been confirmed by all the people who have taken Calotren. Since Calotren has no stimulants like caffeine and ephedrine, it does not cause a person to feel jittery or have a racing heart. These are the normal side-effects of weight-loss supplements. On the other hand, Calotren has displayed some positive side-effects. It has been noticed that Calotren prevents wrinkling of the skin. This means that there will be no wrinkles on your face and hands which will make you look much younger than your age. Beauty experts are also pleased with the results.

How Much Weight Do You Lose?

Calotren supplement must be able to achieve the very goal that it has been created for. Unless you lose substantial weight after consuming Calotren, there is no use in taking it. But studies state that you should be able to lose 1 pound every week. A calorie deficit of 500 calories should be created per day. Taking Calotren will add about 12 calories every day which is quite negligible. It is expected that you will achieve 86% success with weight loss after taking Calotren constantly for 90 days.

What Are The Other Benefits?

What can be better than if Calotren supplement can provide other benefits besides controlling your weight. The presence of glucosamine and chondroitin in Calotren is a very good sign. These ingredients aid in developing joint tissue. This means that there will be an increase in joint flexibility and also that you will recover better from joint injuries. Looking at all these aspects of Calotren, one can safely conclude that Calotren is an effective means of controlling your weight. There are only advantages to count.
