One of the greatest and most useful achievements in the computing world is
wireless technology. Currently, there are two mainstream wireless
standards: WiFi and Bluetooth. For those unfamiliar, WiFi is charged with
handling high speed networking duties. Bluetooth on the other hand keeps
our desktops clutter free by replacing various peripheral wires. Though
they both use radio frequencies (very similar in range I might add), they
are vastly different standards and require separate adapters. Of course,
adding two adapters to make your computer Bluetooth and WiFi enabled is
certainly a feasible option. It is also a costly and space wasting one. To
alleviate the need for two adapters, Suncore has released the BlueWiFly
Combo USB adapter.
