Mobile Wireless Communications And The Advances In The Field

Wireless communication is, as the name suggests, communication between devices which are not physically connected with the help of wires. Such things like cell phones, remotes for toy cars and TVs, PDAs, radio devices and walkie-talkies can all be put in this category. The most recent use that wireless communication technology has been put to is the variety of wireless headphones, keyboards and even your mouse for computers, and also the GPS tracking in your car which tells you the best route to your destination. The main piece of equipment that everyone typically thinks of when they hear ?wireless communications? is a cell phone or mobile wireless communications.

Martin Cooper is considered to be the father of mobile wireless communications. He succeeded in making the first call from a wireless telecommunications device in 1973. The cell phone has seen a lot of change and evolution since then. Unlike the cell phones today that are adept for so many things the cell phones then were only able to make and receive phone calls. They can not only make and receive calls, but also has a host of very advanced features such as internet connectivity, thanks to the Wireless Application Protocol or WAP and other such technologies. In contrast with the talk time on the phones back then, which was 35 minutes, our phones now can handle over 30 hours; that is a big change.

Early cell phones, or as we can call them the first generation or 1G cell phones, used to depend on the analog TDMA or Time-Division Multiple Access technology alone for communication; then came the 2G or second generation of mobile phones, which depended on the CDMA and the GSM technologies. This enabled the 2G phones to transmit not only the analog voice signals, but also the digital data signals. This revolutionized the whole idea of mobile wireless communications, as the PDAs and GPRS and WAP came into the picture. Phones today are able to be more portable as they are smaller in size. Also, as the carriers were now able to guarantee non-interference of signals over an area even with increased subscribers, mobile usage increased dramatically.

Now we are in the third and fourth generation of mobile communications, more commonly known as 3G and 4G. These would provide features like WLAN and WiMAX which would enable all the future devices to have exclusive IP addresses. Mobile wireless communications has really evolved since Martin Cooper brought us into the future with his mobile telephone.
