The name ‘Wireless Networks’ can cover a variety of meanings and definitions. In this day and age there are all kinds of Wireless communication and operation devices available, ranging from simple, everyday items like the TV remote, to the complex, high quality and expensive items like Nav-mans and Wireless Laptops.

For each wireless device, there is a unique technology behind it. For instance, some mobile phones use the Cellular Digital Packet Data (CDPD) technology, which is a standard for communication between two mobile devices. Other standards include the Packet Data Cellular (PDC-P), General Packet Radio Service (GPRS), High Speed Circuit Switched Data (HSCSD), 1x Radio Transmission Technology (1xRTT, which is related to CDMA), Bluetooth and IrDA (Infer-Red). Bluetooth technology is more related to short distance communications(less than 10 meters) and operates at a slower rate (1Mbps) and on a much lower frequency. This means the Bluetooth is a technology more suited towards smaller devices such as mobile phones and PDA’s.

Some other Wireless technologies, which are not related to mobile phones, are Local Multipoint Distribution Service (LMDS), Multi-channel Multipoint Distribution Service (MMDS) and Wi-Fi (802.11).
One aspect all wireless communication devices have in common is that they all use radio waves, at different frequencies to communicate. Each device uses an agreed radio frequency to communicate to another device: thus, we have wireless communication.
