In an effort to improve client RF Performance, specifically SNR and speed, I would like to consider all the configurable options I have. First off, a bit of background:
Client Connectivity
- The majority of clients connecting are 5Ghz/HT-40Mhz
- All others are 2.4GHz/HT-20MHz.
- The environment is somewhat mobile (by foot) but would not be described as highly mobile.
Client RF Performance - SNR
12% < 20 SNR
38% 20 <> 30 SNR
50% > 30 SNR
Client RF Performance - Speed
25% < 54 Mbps
75% > 54 Mbps
Client Issues
- Client roaming sometimes results in worse connection when just sitting at desk
- Random drops from the network
Airwave flags potential connectivity problems for clients with an SNR of 35 or below. So I use this as my baseline for determining if clients are underperforming. Looking at the SNR numbers above, I would say that at least half of my clients do not have ideal SNR. However, the speeds look good - not sure how the SNR and speed actually relate to eachother. That being said, I think that the network could be tuned a bit to increase SNR and speed.
I understand there are several options that could be tweaked, but I am not sure where to start. I believe I have the following options:
- Adjust transmit EIRP (15 currently)
- Tweak A & G transmit rates
- Set local probe threshold
I've done some basic research on each of the options, but I'm not sure where to start if looking to increase RF Performance. Any suggestions for where to start?
