Networks can be broadly classified into two types: 1. Wired networks 2. Wireless networks Some of the drawbacks of the wired networks had brought the “wireless networks” into the picture. Wireless operations permit services, such as long-range communications, that are impossible or impractical to implement with the use of wires. The term is commonly used in the telecommunications industry to refer to telecommunications systems (e.g. radio transmitters and receivers, remote controls etc.) which use some form of energy (e.g. waves, acoustic energy, etc.) to transfer information without the use of wires.[1] Information is transferred in this manner over both short and long distances. Increased uses of laptop computers within the enterprise, and increase in worker mobility have fuelled the demand for wireless networks. Up until recently, wireless technology was a patchwork of incompatible systems from a variety of vendors. The technology was slow, expensive and reserved for mobile situations or hostile environments where cabling was impractical or impossible. With the maturing of industry standards and the deployment of lightweight wireless networking hardware across a broad market section, wireless technology has come of age. Wireless networks consist of network nodes which makes use of radio communication for the wireless data transmissions. This execution is carried out at the physical layer of the OSI model. The wireless networks have a wide range of advantages: •
