1. EXECUTIVE SUMMARY
Wireless networks have been an essential part of communication in the last century. In this report, it outlines the chosen topic which is “Wireless technologies in LAN environment” and also its underlying principles which it define as a popular option for network connectivity on organization intranets, home networks and for accessing the internet. It provides users connectivity to the network without having a physical network cable attached to the user’s workstations or laptops. This involves the transmitting of electromagnetic signals over the air.
In a LAN environments, wireless technologies may affected by interference and obstacles that block RF (Radio Frequency) signals. So the wireless technologies that used in LAN environment are Ethernet and Token Ring technology. Thus, LANs are traditionally used to connect a group of people who are in the same local area. The working groups are becoming more geographically distributed in today’s work environment.
The underlying principles include the wireless environment which is an often appropriate network option that will grow and improve the demand in manufacture.
Today’s manufacturers have adopted many competing standards for implementing wireless communication. These standards are 802.11b and Bluetooth. Within the network of wireless technologies, there are three categories that divided based on their technologies which are LANs, Extended LANs and Mobile Computing. Wireless LANs and Extended LANs use transmitters and receivers owned by the company in which the network operates. But mobile computing use public carriers such as long distance telephone companies, along with local telephone companies and their public services to transmit and receive signals. One of the principles of the chosen topic is the methods or technique of how data transmit. The method of wireless uses the earth’s electromagnetic frequency
