All the different wireless technologies can easily confuse the average user. It is important to understand the major differences between wireless technologies such as Infrared, Bluetooth, 802.11 b/g/n, and WIMAX. It all depends what you need your wireless technology to do. If you want to transfer high quality sound for example, A2DP or stereo Bluetooth is the way to go. If you need to transfer a small amount of digital data from one IR enabled device to another, while preserving your device’s battery, Infrared is your tool. Wimax is simply like WIFI on steroids. The most important factor when choosing a wireless technology is assessing your needs.
