Wireless network design - Essay Example This paper looks at implementing wireless network in an organization. Why should one use wireless instead of the traditional wired networks, the advantages and disadvantages of wireless network and the components of wireless network. The paper also looks at the configurations for wireless network. The strength of having wireless internet is attributed to the fact that wires or cables are not required to connect each node on the network hence it is cheaper to install and maintain. While interface which results to packet errors and security concerns are some of the shortcoming of wireless network. When designing the wireless network, the main goal is to ensure that services, which were offered by other modes of communication, are offered even more effectively. Therefore, the same data types and services should be available to the users after implementing it. The safety and security concerns of the data on the internet must be well addressed. This is because any person can attempt to access information illegally once on the network. Encryption mechanisms should be implemented to protect the privacy of the users and the organizational data. As privacy and confidentiality is ensured in the design of wireless network, the existing services of the organization should be transparent which means they should be available. The two protocols both operate in spectrum technique in 2.4 GHz band (in the range of 2.4 to 2.4835 GHz) with 83.5 MHz total bandwidth. 802.11 uses; DSSS, CCK and OFDM techniques. The technique has method and mechanisms of adapting to noise, where the 802.11 uses 1 to 54 Mb/s signal rate to protect its protocol from noise. Adaption to noise is done in physical layer in 802.11 where it is transparent to higher layers. This wireless network has capabilities of transmission speeds going to 300Mbps. The frequency range of this technology is 2.4GHz to 5.0 GHz. It is the most recent wireless
