When we talk about wireless communication it was simply a way for people communicate with each other for a certain distance without using any wire. This wireless communication includes voice, data and video transmitting from one place to another within certain wide range area. When the term mobile was put into the sentence then it mean that we talk about specific wireless communication that help mobile people to use certain device such as cell phones, computing devices, PDA and other communication device that was portable and easy to carry around anywhere.

Although the Mobile Wireless Communications idea has been widely known for a very long time ago, but it was going to major breakthroughs since internet becomes part of person''s life. At first, the wireless communication limited to send and receive voice but later it has gone to a whole new level.

People no longer communicate with voice only but they also can exchange messages, transferring files, an even collaborative computing. Some of this major breakthrough happens because of the internet connection.

But beside the hype of internet and how it affects  the way people communicate wirelessly, the wireless technology itself has developed from the very simple function to broader function. Start with 1G system or the Analog system, then move to 2G systems or the digital system where the term of GSM (Global System for Mobile Communication) and CDMA (Code Division Multiple Access) was introduced, then it moves to 3G systems and 4G system. The 3G and 4G system promising higher data speed service and in the end provide higher wireless data rates. With the whole features that come from wireless communication, the user will get the best benefit of all. They can carry their cell phone wherever they go and still can communicate with other people and with the promising system of 3G and 4G it seems like everyone can get the benefit of higher data speed that was becoming an important need in this modern life.
