Hello,

I would like to use Nstream on P2MP systems to take advantage of the polling feature.

Is Nstream more Susceptible to noise/interference bacuase its not 802.11?
Will I still need to run wep or a vpn over the top to make it secure & prevent sniffing?

Will I get more clients per AP eith Nstream?

Thanks :slight_smile:

I don’t run nstreme for p-t-multipoint. So I’m definetely not an expert. But polling should help out greatly to keep the AP chatter down. I would think it would allow you to run more clients. How many more, I can’t answer. Also, the framer-policy should help you to optimally fit more data into each packets, which should really help if any clients send small packets. The old Karlnet software had a similar product called Turbocell, which I have used. Nstreme appears to be similar but better.

Here is what the manual says about Nstreme:

Benefits of Nstreme protocol:

  • Client polling. Polling reduces media access times, because the card does not need to ensure the air is “free” each time it needs to transmit data (the polling mechanism takes care of it)
  • Very low protocol overhead per frame allowing super-high data rates
  • No implied protocol limits on link distance
  • No implied protocol speed degradation for long link distances
  • Dynamic protocol adjustment depending on traffic type and resource usage


    The one thing I’ve noticed is that if you are doing alot of polling, it is a bit much for the RB532’s. You’ll probably have to use a P3 or higher on the base station side.
