The development又兵 situation of WiFi 著上chip in internet of thin答用gs era

      &爸能nbsp;   爸哥  &nbs低的p;   In低友 the trend of internet of t算遠hings , in year 2015 , WiFi chip ush電慢ered in the first explosiv玩如e rise , the total s算兵hipment exceeding東空 30 million units , whi地時ch was three times of 紅靜that in year 2014 .

If  adding WiFi scheme這下 to it ,an addi說個tional burden will 朋唱occur , which is not beneficial to the能村 promotion of internet of分喝 things in the society . Then , d水放riven by the huge demand in internet o對黃f things , big internationa農作l chip design manufacturers be費妹gan to integrate MCU with WiFi to red房議uce the chip area and cut 銀美down the cost of chip scheme ( now t藍數he module price is abou影雪t 9 Yuan ) , the most typical r能短epresentative of which 員他are Qualcomms Atheros 4004 T外她1 CC 3200 , Real tek 8711看雜 etc . On the other hand , the窗舞 domestic chip design compa體藍nies are unwilling t身民o lag behind .

Most of the 時區RF are analog circuits . T熱少hey first have high techni北路cal requirements for the en電自gineers technology 空短.
