Wireless Network

Introduction Wireless network is indicated to a telecommunication network whose interconnections between nodes are implemented without the use of wires, such a computer network. Nowadays, wireless network has become the important thing in telecommunication. This sort of technology has been used for over a century and remains synonymous with radio. In 19th century, Guglielmo Marconi invented a radio and made his made his mark in the world of wireless technology. At that moment, Marconi was about to produce detect radio waves from long distance. In 1896, the Wireless Telegraph and Signal Company Limited was established and became the first radio actor in the world. The first wireless signal was sent using Morse Code. Signals were received across the Atlantic in 1905. However, this kind of technology was first introduced during World War II when the army began to sending battle plans over enemy lines and when Navy ships commanded their crew from shore to shore. As the time goes by, wireless network proved its functions and advantages so businesses and schools have expand their computing arena by improving their wires LAN (local area networks) into wireless LANs. Therefore, wireless technology revolves in every house, classroom and business around the world. This paper will discuss the type of wireless network, the function, how wireless should be implemented, pros and cons of having wireless network wireless, how this wireless can be managed, what the security issues of wireless technology, when it is to be implemented in institution, and how this can be monitored and controlled.

The Types of Wireless Network The following are the types of wireless network:
1. CDPD (Cellular Digital Packet Data) is a specification for supporting wireless access to the internet and other public packet-switched networks over cellular telephone networks. CDPD supports TCP/IP and Connectionless Network Protocol (CLNP). CDPD utilizes the RC4 stream cipher with 40 bit keys for
