Tenda U1 is built to compatible with Windows10/8.1/8/7/XP/Vista, MAC OS 10.6~10.11, and Linux operating systems. Most of the computers (desktop computers or laptops) comply with the USB adapter and can connect to the Internet through it easily. 360 ° omni-directional rotating antenna for perfect 2.4GHz 3.5dBi high gain detachable antenna with 360° omni-directionanl rotation provides a remarkable signal strength and corverage. 2T2R high transceiver technology Combining with internal and external antennas, 2T2R dual-channel enhances the signal penetrating ability, solve dead point ( corner and long distance signal) problem, and make a stable and perfect signal transmission. 4-layers PCB with high-quality materials It takes 20 RF engineers, 5 hardware engineers and 10 software engineers more than half a year with thousands of tests to put 4 layer PCB within ultra small space. Electrical stability and radio frequency anti-interference is 120% higher than 120% higher than the normal 2-layer PCB.
