Wireless Networking - Essay Example Individuals with desktop computers connected to Wide Area Networks (WANs) and Local Area Networks (LANs) in their places of work may need to be connected while away, which is literary impossible with the concept of wiring. Here is where wireless networking comes in. A wireless network is a system that receives and transmits radio signal through the air from one point to another. The term wireless network often refers to a Wi-Fi or 802.11 networking, from the protocols that control the wireless network concept (Kumar, Manjunath & Kuri 2). Wireless networks are consistently proving their worth in today’s world, with coverage of important services like FM radio, AM radio, satellite television, broadcast television, and satellite internet, which all form a basic part of our lives. The history of wireless networking discovery takes us back to 1888 when Heinrich Herz discovered the first radio wave. In the years that followed, other scholars were further developing the radio frequen cy concept. Marconi was the first known man to successfully transmit and receive a message using radio waves in a distance of two miles, labeling him the â€Å"father of radio†.... The resultant second generation WLAN was upgraded and was four times faster, with an operational speed of 2Mbps. Further developments led t the design on the third generation WLAN, which are in use currently (Kumar, Manjunath & Kuri 23). The Institute of Electrical and Electronic Engineers (IEEE) 802 committee in 1990 set up the 820.11 Working Group that would be the foundation of the WLAN standard. Among the specifications of the standard was an operating frequency of 2.4GHz ISM band, and consequently approved the IEEE 802.11 to be the first WLAN standard with frequency of between 1and 2 Mbps. Building a wireless network will require an access point, which receives and sends radio signals, as well as acting like a repeater. Another vital device required in all the devices in the wireless network is the wireless network card. A desktop computer usually has an internal card, and may or may not have antennas. Notebooks have a PCMCIA extension slots for the card, if not installed from t he manufacturer. There are two basic forms of configuration for a wireless network: infrastructure and Ad-Hoc. An infrastructure wireless configuration constitutes more than one access point connections to an already existing single wireless network. This will enhance the sharing of resource among the devices in the network, like the internet and printers. Here, a computer acts like a hub that provides connectivity for the other computers in the network, hence connecting a wireless LAN to a wireless LAN (Kumar, Manjunath & Kuri 54). On the other hand, an Ad-Hoc wireless network configuration connects one device directly to another device on the network, hence the common reference to peer-to-peer network. All devices can connect directly to each other, but there must be one that is
