Solution for reading sensors

Hello,
I have to connect from 1 to 6 pressure sensors to a my device.
Speed between one sensor and my device is about 100 B/s.

I would like to ask, what’s best solution for this network ? What module choose ( distance between sensor and my device is ± 30 meters in indoor ), what module choose for recieving + how it works, if 6 sensors will be sending data to my reciever connected to my device ? i mean, if 6 sensors will be sending data at the same time, what will happend ?
What about reliability ? network latency ?

Thank you for ideas, opinions.
