Re: [AFMUG] Control Slots on Canopy

[Sean Heskett]

We use 2 control slots on FSK and 8 slots on 450.

As others have said, control slots on the 450 are a negligible amount of
data so why not be generous and ensure that there is always enough for
uplink scheduling.

you can adjust the range/download percentage.
for us it would be too difficult to manage the number of ap's 100's & 450's..
just keep range/download the same as 100 series, double the slots, perfect match to sync

[Ken Hohhof]

I thought insufficient controls slots affected registration as you say, and 
also upstream traffic, since controls slots are used by SMs to announce they 
have data to send and to request allocation of upstream data slots.

 

Given the additional capacity of 450, I thought the advice was to be generous 
with control slots, we typically use 8.  With 100 series you didn’t have that 
much capacity and allocating more to control slots was a decision not lightly 
made.

can't you adjust the distance to make them sync as well if you don't want to 
add more control slots? It is my understanding that the main problem that 
arises from not having enough control slots on a heavily loaded AP is that new 
SM's take longer to register to the AP but once they are registered it is fine.

I just read in a Cambium notes file that control slots should be set to 4.
I have a competitor that is running 6.

What is the best setting on a 20 Mhz channel on the 450? 20M with 75% downlink.
What is the tradeoff with the change of the control slot in setting?

[AFMUG] Control Slots on Canopy

We have always set our control slots to 3 on all our canopy platform.

I just read in a Cambium notes file that control slots should be set to 4.
 I have a competitor that is running 6.
