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 a breakthrough in computing networking technology, and versatility of this technology has caused 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. 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. Examples include:
Wi-Fi: Primarily associated with computer networking, Wi-Fi uses the IEEE 802.11 specification to create a wireless local-area network that may be secure, such as an office network, or public, such as a coffee shop. Usually a Wi-Fi network consists of a wired connection to the Internet, leading to a wireless router that transmits and receives data from individual devices, connecting them not only to the outside world but also to each other.
Cellular: most often associated with wireless phones, a cellular network use connected transmitters, or cells, that enable the user to move about while remaining in contact with the network. Cells transmit at low power levels so as not to interfere with each other and may be spaced far apart in rural areas or close together in cities. Cellular networks rarely offer complete coverage, and due to a number of factors, you may have experienced "dead zones" with no coverage at all. Also, when usage is extremely high in a specific area, bandwidth may be insufficient to handle all the traffic, and the system may block new calls until bandwidth becomes available. The evolution of cellular networks is enumerated by generations. The first generation was completely analog and supported the first wireless phones. The second generation, or 2G, used a number of different digital standards to support compact phones, leading to the wide adoption of wireless phones. To accommodate a growing need for data as well as voice, 3G offered further bandwidth. Today's widespread use of smartphones has spurred the wireless providers to build out 4G networks, which support high-speed data for phones such as the iPhone 5 and Samsung Galaxy S III.
Bluetooth: While both Wi-Fi and cellular networks enable connections to anywhere in the world, Bluetooth is much more local, with the stated purpose of "replacing the cables connecting devices," according to the official Bluetooth website. That's precisely what Bluetooth does; it connects iPods to car stereos, wireless keyboards and mice to laptops or cell phones to the ubiquitous hands-free earpieces. Bluetooth uses a low-power signal with a maximum range of 50 feet, but with sufficient speed to enable transmission of high-fidelity music and streaming video.
