QuickerTek today announced its new QuickerTek N Antenna Upgrade, offering better wireless performance than its previous model. The new Antenna Array Upgrade can be purchased three different ways: a customer-installed upgrade is available for US$129.95, QuickerTek can install it on the customer’s Base Station for $179.95, or an already-upgraded Base Station is available for $349.95 for plug-and-play use. Once an AirPort Extreme Base Station is upgraded, it retains backward compatibility with previous wireless standards. It works with all IEEE 802.11 b/g/n networks and performs to it’s full speed (near 300 mbps) potential with 802.11n rated hardware, notes the company.
