| Abstract: | Objective To design a low-power Wi-Fi access solution with internet of things to connect sensors network to Internet. Methods Low-power ARM main controller, Marvel188W8686 network chip and light TCP/IP were involved in the solution for Wi-Fi access, establishing TCP connection, data sending and etc. ~ Wi-Fi network could be accessed to Internet rapidly, with the maximum current not more than 170 mA and sensitivity of -85 dBm. C.onchmion The solution results in low-power, high-speed and multi-protocol-compatible Wi-Fi access, and thus is worth applying to internet of things gateway and sensor node. |
