The UMTS Microsphere antenna provides wireless connectivity for Next Generation (3G) voice and multimedia applications in buildings. The low-profile UMTS Microsphere works as a seamless upgrade to existing in-building wireless systems or as a stand-alone solution to provide 3G devices with enhanced connectivity. UMTS Microsphere can be installed in almost any indoor space via a simple ceiling mount. The antenna's small size and sleek design roughly the size of a playing card ensures that once installed, it remains virtually unnoticeable. The UMTS Microsphere features an omnidirectional pattern that is suited for handheld and other mobile devices that can be used indoors. By operating in the 1920 - 2170 MHz frequency range, the antenna supports all 3G UMTS voice and data applications. The antenna offers a high performance peak gain of 3 dBi and a VSRW of 2:1.
