Wireless technologies are very famous and have taken over our life’s in daily to daily task, and it is popular among the techno people and the modern researchers. The time wireless technology was discovered, it had all the potential of the world to take over many previous technologies working with help of wires. It has been breakthrough in computing networking technology, and versatility of this technology has cause it to diversify in many other fields which are not even directly related to computers. There are lots of wireless technologies now being into use which helps us to compete in the race of computer networking and be up to date in this technological World.
Computer networking is a very vast and advanced field which has been implemented on many aspects of technology. In computer networking, there are so many devices which are used for networking purposes. Wireless technologies really provide the convenient and easy approach to communications between different areas that are far behind from the different types of the modern and the latest technologies. Types of wireless technologies were designed by the scientists because people who are away from their homes, they can avail such opportunity of using the internet at very high speed and be in touch with others for the sake of their business enhancement in the best possible ways of communication between two places.
Eighteen major types of wireless technologies exist, containing a large number of subset technologies that range from ATM-protocol based (which sells at approximately $200,000 per data link, to wireless local-area network (WLAN, which sells at less than $500,000 per data link). Frequencies of the different technologies travel between several hundred feet (wireless LAN) and 25 miles (MMDS).
The process by which radio waves are propagated through the air, the amount of data carried, immunity to interference from internal and external sources, and a host of other characteristics varies from technology to technology.
Wireless technologies are differentiated by the following:
- Protocol - ATM or IP
- Connection type - Point-to-Point (P2P) or multipoint (P2MP) connections
- Spectrum - Licensed or unlicensed
