Introduction to wireless and Bluetooth technologies
Wireless technology provides the ability to communicate between two or more entities over distances without the use of wires or cables of any sort. This utilizes radio frequency (RF) as well as infrared (IR) waves.
Table 6.1 outlines the different wireless technologies with the IEEE standards they support, the radio frequency that they operate on, data bit rates, and network ranges and size:
