I am working on a project where we need many devices to talk via 900 MHz with some strict
timing requirements. Is there any data available about Rocket M9 performance transmitting
small packets based on the number of clients connected?
For example, if there are 50 clients each with their own Rocket and they want to broadcast
small packets to each other (assuming good signal strength) at 10 hz how many of them will
be dropped? What would be the typical transmission time?
CSMA solutions won't work because they all start colliding and the transmission time goes
up very quickly.

So 50 clients * 49 packets * 10 times per second = 24,500 pps?
I think that's pushing the limits of what a Rocket M can handle.

Thanks for the response. It's actually 50 "devices" and each device has a Rocket M. Each device
will be sending 1 small packet at 10 Hz to be received by all the other devices. It's just a broadcast
msg. Each device then needs to support 500 pps (1 out and 49 in at 10 Hz).
The transmission distance is relatively short (< 1500') although there may be obstacles. Antenna would
have to be omni-directional.
