This is a great thread, fun challenge and there are many suggestions to help you work through this that have educated me
Without knowing the facility size, number of hotspots and the industry involved it’s hard to guess what the problem is, below are some tips based on my experience setting up warehouses for many years. I’ve encountered all of them in one form or another causing dropouts.
If you’ve not already done so you may want to document any interference hotspots within your facility and correlate those to the dropouts. Based on your description I suspect something below may be culprit. You may be able to mitigate the problem by relocating the WiFi hotspots closer to the interference source or relocating the source if feasible.
Lights, fluorescent or sodium or mercury vapor lights along with newer non filament light bulbs.
Electric motors that run compressors, presses, fans or either equipment that require high voltage.
Are you using radio transceivers for voice comms in the facilities, if so what part of the RF spectrum (frequency) are they operating in.
WiFi uses something called adaptive modulation that employs varying levels of forward error correction which allows the devices to work 99% of the time when signal strength momentarily weakens. The limitation of this is the 1% of the time when it drops and resyncs which normally takes seconds and goes unnoticed in most cases until you require continuous connectivity as you and others currently do.

Hi Kevin,
Thanks, we were hoping to replace the Warehouse Staff's current desk based Laptop / PC with a ruggedized Tablet PC such as a the WINMATE M101BK, as that offers the all the Function Keys. not many small format Windows Pc's, offer this. Our ERP solution makes extensive use of the function Keys from F2 through to F9
This would keep the same number of end points we currently have, and thereby not increasing the requirements for a further number of SB Client licences
So whilst the users working in the "aisles" and on FLT's will probably not be running reports, when they get back to their workstations, they will need full access to their current Menus
If there is still no "terminal" screen in SBXA, it might still be worth investigating the benefits of SBXA, to see if that addresses the WIFI dropouts, and then just re-engineer those processes they do need to run in the Warehouse
BTW. we are likely to have to rollout "mobile" use across the Factory production floor as well, so getting it running in the Warehouse becomes more than a POC exercise
I look forward to hearing from you again once you've had feedback from your Product Manager Colleague
Many thanks
Andy

Are the devices in question running reports ?
If not you can continue to use CHAR and GUI as required and just move over the people using the devices, one of the things that we did not communicate very effectively about SBXA is that you can still connect in CHAR and GUI and run exactly the same as you did before.
If they run a small subset of the reports it might be worth the effort to put a GUI front end on them to allow them to do what they need to do.
I moved away from SB a few years ago so I cannot comment on terminal functionality being added but i will raise the question with a current Product Manager to see.

Hi Kevin,
Thanks for the comments, i had not realised in the change of connectivity protocol
We are still using the GUI from within SB Client and not SBXA, being a 35 year experience PICK veteran (Prime, PI OPEN, Universe) I still prefer Character as my go to screen choice, but needless to say all the "Users" only get to see the GUI !!!
When we last upgraded Universe back in 2018 one of the main reasons for not adopting SBXA was that at that time, there was no "terminal window" so any of our Retrieve Reports that had in screen prompts <<Enter Start Date>> or <<Enter Range Name>> as typical examples, stopped the migration to SBXA as being viable.
I did raise this with Rocket Support back then, but am not aware it got resolved ??
As we had and still do, we are very much reliant on me to Manage all things Universe, we have limited resources, so don't really have the time to re-engineer all the Reports (would need to review over a 1000 to see which are still running live across multiple business) with new Screen Based Gui Forms just to get round the lack of a terminal window, as the conduit for the screen prompts.
We also have 100's of basic programs that also prompt for user input and or display their progress status, which would also have to be redesigned
Also there would be other financial considerations in Migrating to SBXA as our Business System, (IBS from K3) which itself would have to be validated in the latest version of SBXA, and all of our MODS would probably have to be reapplied, as we would almost certainly have to upgrade to a newer version of Universe, we are currently on 11.2.5
So I would be interested to know if the lack of a "terminal" window in SBXA was ever resolved ??
Thanks
Andy

One thing that has not been mentioned so far that may be of interest to you is that if you move to SBXA the new client is not telnet based so will work much better for you in this type of environment. If you are already running a GUI application today it is not a very big step to move to SBXA, if you are running a character based solution then part of the upgrade is thinking about how to present your application in GUI.

Hi Guys,
we would like to go Paperless in our Warehouse for our Pick & Pack operations.
We currently us SB Client on Windows Laptop and Desktops as the interface to our Business system (IBS from K3),
The Business app makes extensive use of F2 and F3 keys and other keyboard input and as such does not lend itself to Touchscreen only use, we currently have any plans to go over to Barcoding at the moment (Thats a long story i shall not bore you with just now)
We have as an experiment in our test system, be investigating using small 10" Ruggedised Windows Laptops, for both mobile and for use on Fork Lift trucks.
However we are getting significant dropouts from the SB Client Sessions, as we move around the warehouse,
We use Meraki for our WIFI and the signal strength from the AP's looks good and we can browse the network and access MS TEAMS, without issue.
So this suggests to me that the Meraki's can't currently maintain the transition from one AP to another for the SB Client user sessions.
Obviously we cant go live until we have a robust connection across the network.
So this is where i need your input, have any of you out there successfully got SB Client running via WIFI in a truly mobile Warehouse / Factory environment and what did you do to achieve this, even better if there is anyone Running SB Client and Meraki WIFI
Many thanks
Andy
