Wireless Technologies 2 Wireless Technologies As modern technology advances in complexity, and companies become more reliant on technology to function, the utilization of wireless technology increases. There are four options available when choosing a wireless technology type for a Wide Area Network, like Radio Frequency, Microwave Signals, Satellite Signals, and Infrared Signals. Radio Frequency (RF) operates between 10 KHz and 1 GHz, and can be either low frequency or high frequency. Low Frequency RF can pass through objects, but offer a low bandwidth and distance. High Frequency RF can travel much farther distances, providing better service, but cannot pierce objects like Low Frequency can (Regan, 2004). This restricts High Frequency to line-of-sight transmission, as any object in its path will cause the transmission to be reflected. With such a large range of operating frequencies, many bands of frequencies have been established to work for one purpose (Regan, 2004). There are number of transmission options for RF such as Spread Spectrum Signals, Direct Sequence Spread Spectrum, and Frequency Hopping. These options are used to prevent unauthorized access of transmitted data in addition
