An Overview of the Wireless Intrusion Detection System

Wireless technology has emerged as a very popular alternative to wired technology in recent years and has become readily available in more networks everywhere, whether it is for a home, an office, or any size of business. Wireless or WiFi technology is another way of connecting a number of computers to a network without using wires. WiFi uses radio frequency to connect wirelessly, so there is greater freedom to connect computers from anywhere in a home or an office network. This technology is similar to how a cordless phone would work, using radio signals to transmit data from one point to another. However, wireless technology has restrictions on accessing a network, such as the network range. Two types of wireless networks are Wireless Local Area Network (WLAN), and Wireless Personal Area Network (WPAN). Bluetooth is the industry standard wireless technology that WPAN uses. These devices operate in a range of up to 30 feet away. Compared to the WLAN, the speed and wireless operation range are both less with the Bluetooth, but this technology does save on power and makes it more ideal for a number of personal devices, such as mobile phones, PDAs, headphones, laptops, speakers, and other battery-dependent devices.
