Tenda U1 is built to compatible with Windows 10/8.1/8/7/XP/ Vista, MAC OS 10.6~10.11, & Linux operating systems. Most of the computers (desktop computers or laptops) comply with the USB (Universal Serial Bus) adapter & can connect to the Internet through it easily. 360 ° omni-directional rotating antenna for perfect 2.4 G Hz 3.5d Bi high gain detachable antenna with 360° omni-directionanl rotation provides a remarkable signal strength & corverage. 2T2R high transceiver technology Combining with internal & external antennas, 2T2R dual-channel enhances the signal penetrating ability, solve dead point (corner & long distance signal) problem, & make a stable & perfect signal transmission. 4-layers PCB with high-quality materials It takes 20 RF engineers, 5 hardware engineers & 10 software engineers more than half a year with thousands of tests to put 4 layer PCB within ultra small space. Electrical stability & radio frequency anti-interference is 120% higher than 120% higher than the normal 2-layer PCB.
