Wireless network problem

Hello everyone.
i have 1 ip camera (parantek), 1 embstar m16 wifi module with openwrt and 1 ubiquiti loco m2 with openwrt. i want to make a network like;

Camera>m16>loco>pc wiev

i use m16 for wireless transfer from camera to pc, but i want to use another device for connect pc and m16. so i can get camera wiev directly from embstar but i cant use patch antenna for longer distance. if i use another device between pc and m16 i can get longer distance to transfer i think. but i dont know how ll i set it up between pc and m16. Please someone help me to setup this.

Thank you a lot.
