Hi,

Guys, I need your help.
I have the following setup:
- 11 microcontrollers with RJ45 interfaces spreaded across a warehouse ( 100meters length \ 20 meters width )
- a "command center" in the center of the warehouse

I need to connect each microcontroller with the command center in order to receive and sent data.
What models would you recommend ?
I would like to use
1 x RB951G-2HnD
11 x Groove A-52HPn ( with 6 dBi 2.4GHz omni antenna )

That will work. Unless you have a specific requirement to use 2.4GHz, I would switch it over to 5GHz. You could use the groves for all of them and remove the RB-951 so that it can be 5GHz... ,but you may have other reasons for using the RB-951 as well.
