Computer hardware is no longer a major barrier to wide use of wireless information systems. Wireless technology is evolving and becoming the preferred choice for connecting hardware and transferring information. Employing a wireless system allows corporations, like cruise ships, to provide a wireless service to its passengers without comprising information security. Without wireless technology this service would be impossible.
To set up a basic wireless network, you will need a network card/adapter, a wireless router, and access points. The network card is the most important hardware component of wireless networking. The wireless router and access points are used to increase performance, accommodate more computers, and increase the network’s range. Network adapters are used to interface a computer to a network. They can be found as a traditional PCI card, PC Card adapter, USB adapter, media adapter, or an integrated wireless adapter chip. A wireless router allows multiple devices to access one internet connection. Through radio frequencies, data is transferred between devices connected to the network. Access points serve as the central receiver and transmitter of these radio frequencies. Other factors to consider when setting up a wireless network are compatibility, expenses, limitations due to distance and building structure, and Wi-Fi network security.
Wireless network technology, also referred to as WLANs, uses an industry standard known as IEEE 802.11 that enables computers to communicate via radio frequencies instead of cables. The 802.11 network is available as 802.11n, 802.11g, 802.11b, and 802.11a. These networks are not all compatible. They can differ in radio frequency spectrum, speed, and range. The 802.11n, 802.11g, and 802.11b standards operate on a 2.4 GHz radio frequency. Using the 2.4 GHz frequency is less expensive, but is also
