This Page is written by Saad Inam = Wireless Computing= Wireless Computing, also known as wireless networking, refers to computers (one or more) connected wirelessly to each other and/or to the internet. Wireless communications occur through the use of electromagnetic waves from one node to another. In order for the computers to be connected, there is usually a common point of connection (such as a router) to mediate the flow. Wireless computing can be set up in different ways like Wireless Personal Area Network (PAN), Wireless Local Area Network (LAN), Wireless Metropolitan Area Networks (MAN), and Wireless Wide Area Networks (WAN).

Relation to Computer Science
This Topic relates to computer science in several ways. Firstly, it is a extension of computers and their abilities. Secondly, the computers need to know how to send and receive information as well as how to connect to a wireless network. This is where computers scientists come in; they have to program things such as driver so that the computer can begin to wirelessly compute.

History
Wireless computing was developed from technologies such as the radio and the television antenna. Since the 1800s, wireless technology has been developing and improving, becoming faster and more ranged. The start of radio wave technology was in 1888, when Heinrich Rudolf Hertz produced his first radio wave ever. By the 1970s, the technology of radio wave had increased greatly, which gave way for Norman Abramson and a group of researchers under his command, to create the first Wide Local Area Network (also known as WLAN). It was named “Alohanet”. This WLAN consisted of seven computers all communicating with each other. Later in 1972, the range of the WLAN was increased to include the Arpanet WLAN system on the mainland. Development did not end here; a second type of WLAN technology was created, one which had communication ability four times faster than the original and with no interference by small appliances and industrial machinery. A third WLAN system, with the speed of 2Mbps, was created. In 1997 the 802.11 created a standard data communication format for wireless called the IEEE 802.11. This standard is still used today with different sub categories (802.11a, 802.11b, 802.11g, 802.11n )

Personal
The use of personal wireless computing is also referred to as a home network. With the release of new Operating systems such as Windows 7, creating a personal home network has become fairly simple. By creating a home network, computers are able to share printers, documents, videos, music, and pictures. Also, If a router with internet access is connect, the computers wirelessly connect will be able to access the internet through it.

Business
There has been a big shift where businesses begin to adopt wireless technologies. This brings an advantage to the business, as there is no hassle with placing wires to connect the computers. It also allows for mobility where the computers will stay connected as long as they are in range. Scott Carlson states that “The [wireless] technology is good for the bottom line. Wireless technology often is less expensive than standard wire-and-wall-jack installation.”. another positive for a business. A server can also be created in order to centralize company data as well as increase security.

Public
Public wirelesses computing (also known as “hotspots”) are becoming more available to the public. These types of wireless (usual WLAN) can be found at locations like airports, convention centers, hotels, and marinas. They consist of a user friendly interface and most do not use passwords for access. If not well maintained, the network can be infected by viruses much more easily then a Personal and Business network.

Client Adapter
In order for the Computer to be able to compute wirelessly, it requires a Client Adapter. Most laptops come equipped with one already installed. For computers, one can be installed in the motherboard or installed through the Universal Serial Bus (USB). For the Adepter to function correctly, a device driver is required.

Wireless Router
This device can moderate the traffic (e.g. direct packets to the right computer), and give a location for all the computers on the network to connect too. It can also provide internet to all the connected computer (if a modem is connect or the router features modem like functions).
