Hi everyone,
I have just get two SXT lite 5 ac devices and I need to set up a 3km transparent wireless point-to-point network link. I have already set up the basic configuration (one device in bridge mode and the other one in station bridge mode) and the link is working, but I would like to understand better the impact that some configurations will have on the link performance (stability, reliability, latency…).
I just need the link to support 100Mbps rx and 100Mbps tx simultaneously (200 Mbps aggregated), no more bandwidth is needed so I don’t mind if my link throughput is 200, 300 or 1000, I just need 100/100, but I am looking to maximize its stability and reliability, as well as to minimize the latency.
Channel Width:
In the area where the link is going to be installed there are no interference problems because there are no other systems working in the 5GHz band.
The question is, will a larger channel width offer better o worse performance? As I said above, more throughput does not mean better performance in my case, if I have at least 200 Mbps aggregated. When I say better performance I mean more reliability, less latency, etc. Which channel width will be the best in my case?
Wireless protocol
802.11, nstreme or nv2, which one will provide more reliability, stability, security and less latency for my 200 Mbps 3km transparent wireless point-to-point network link?
Antenna Gain
What does this value mean? Which antenna gain do you recommend me to use?
Tx power
Card rates, default, all rates fixed, manual… Which are the differences and which configuration will be the most appropriate for my link?
Data rates
6, 9, 12, 18, 24, 36, 48, 54 Mbps… all are selected by default. Wouldn’t be the link more stable if we select just one rate so the link always uses the same one?
Cell radius
In the NV2 menu there is a cell radius value which I can’t set lower than 10 km, what is it for? Which value should I select for my 3km link?
If you have any other considerations or recommendations for my link to maximize its performance I would be very grateful to read them all!
Thanks!
