R710 coverage and features

[chennai_itsuppo]

Hi We are currently using ZD1200 with 5 R700 AP and planning on adding two more AP but there is no enough channel on 5GHz 80 MHz so we move to 5GHz 40MHz but we are not so impress with the performance. And i heard that R710 has better coverage compare to R700. Can someone confirm that for me please... also if its true how does it enable better coverage on 5GHz ... i mean both R710 and R700 when deploy on 5GHz 80MHz they are both seems running on the same frequency to me ... please need clarification.....

Hi John thank you ....
in two of our APs mostly 50+50 max clients and the rest will be distributed on the rest of the APs and we have 5 AP and yesterday got a demo R600 AP from our vendor...
When we are on 5GHz 80MHz total airtime utilization is good i mean it was never above 5 for the ap with the most clients
But on 5GHz 40MHz i can see two of the APs which has the most number of clients will have a total airtime utilization of above 10 and sometimes 12

and thank you clarification on the MU-MIMO now i know it will work only for MU-MIMO capable devices....

Sure thing! 5%, 10% or even 12% airtime utilization is not that bad. Any particular reason why you'd like to keep it to 5? It sounds like you have plenty of capacity left on your network. Is something not meeting a performance goal you have from the clients' perspective?

You should not be worried about airtime utilisation until it is above 75%

(i was thinking MU-MIMO will works just like that for all devices)
Average through put between AP and ZD is 700M - 912M up n download depending on the number of clients on the AP and distance between the AP and ZD
And clients througput varies but a would say 400mbps for ac capable devices and 300mbps for n capable devices.

That's pretty good and about the capabilities of the technology.
