RF WSN Network

I have to make a Wireless sensor network where 10 machine are installed , each machine is having 16 sensors , every machine is communicating to the local PC wirelessly. Further this Local PC is connected to my centeral PC using wireless network . I have to use 8 local PC’s so for that I am looking for wireless solution with high reliability. So suggest suitable solution for me

I’m not sure I can make a good recommendation with the above information. more information on the enviornment along with what kind of data you are collecting would also be helpful. How often are you sampling data and what kind of distances do each of these ‘machine/sensors’ network have travel?
