Beamflex causing roaming problems with warehouse devices
We’re having a really tough time getting 25 R610’s working in a warehouse environment with Vocollect (Honeywell) T5 devices that are used by the warehouse personnel. After a lot of investigation, review of logs, and packet captures it appears that the issue is around the T5 devices misreading the signal strength of the AP’s and staying on ap’s with poor coverage. The T5 devices are deigned to be used by operators that are driving forklifts around a warehouse so they are extremely sensitive to changes in the RF environment, always looking for a better ap.
Unfortunately they are using the AP beacons to read signal strength, so even if they are connected to an AP with great coverage, when they see a beacon from that ap with a weak signal, so when they see a beacon from an AP that physically does have good coverage but shows as having a weak signal, they assume the operator has moved from that AP and they imediately scan and jump to another ap.
This process seems to repeat over and over again, resulting in a terrible experience for the client devices. These T5 devices do use older 802.11 b/g radios, and the newer devices like ipads, iphones, androids and laptops work great. Unfortunately the T5 devices are mission critical so I need a way to get them working reliably.
Before Ruckus was in place, the warehouse was using Ubiquity access points, which worked great for the t5’s, just not for anything else...
So we’re kind of stuck now... overall it seems like both the Ruckus and the T5 devices are trying to independently solve the same problem but they’re conflicting with each other resulting in terrible device experience.
We’ve tried just about every configuration change possible including adjusting signal strength up and down, changes to power management mode on the devices, forcing b, forcing g, bss minrate, smartroam, changing roam thresholds on the device, etc.... but nothing seems to get the devices to believe the rucks signal is as strong as it actually iis because the beacons show lower strength.
Does anyone have any experience with client devices that are using beacons to identify signal strength, and have any strategies to prevent them from getting confused by beamflex? Vocollect/Honeywell has asked if we can turn off beamflex, but it seems like that’s built in to the hardware and not changable.
I have opened a case with Ruckus tech support but haven’t been able to get past the “Just reboot It” stage... I don’t think they understand we have a fundamental problem with the interaction of the devices and beamflex.
Thanks for any thoughts....
