QuickerTek has introduced the Q4 (http://www.quickertek.com/products/Q4.php), the fourth generation Quicky. Offering an improvement over the previous models, the new Q4 works in both 2.4GHz and 5.8GHz wireless modes and powered from the USB port.

It’s designed as a solution for users who often find themselves accessing networks at work, school, hotels, coffee shops, airports and other environments where signal strength and speed vary and who want maximum wireless performance. Any Mac with a USB port can take advantage of wireless networking, whether the Mac has an AirPort wireless network card or not.

The dual 3 dBi antennas provide the speed necessary for 802.11a/n wireless that runs in the 2.4GHz and 5.8GHz range. Users may choose to upgrade these antennas for even greater distance and wireless speeds.

The US$125 Q4 clips to the Mac laptop case and is powered from the USB port. Q4 works on any Mac with any open USB port with Mac OS X 10.5.8 or higher. It conforms to the wireless standards 802.11a/b/g/n. In fact it, should work on most if not all wireless networks, especially modern ones like; D Link, Linksys and Belkin just to name a few. The Q4 supports 64/128~bit WEP, WPA2 (AES with IEEE 802.11x) and WPA(TKIP with IEEE 802.11x) wireless encryption.

Like most QuickerTek products, the new Q4 is backed with a one-year warranty on parts and labor. The Q4 can be purchased for $125.00 (USD) from QuickerTek’s web store or from a participating resellers.
