wireless/citrix expert advice needed in logistics warehouse

mikey250 used Ask the Experts™
hi currently doing some work for a logistics company with metal everywhere just like in an airport where they sort out  parcels/baggage.

development team:

there is a development team in place who would have the knowledge/experience around the off the shelf software that has been designed to fit there clients business model and obviously being aware of the  hardware/software requirements prior to rollout in order to run a seamless wireless system.

physical network diameter:

- not sure of the acres of land but one warehouse is heading upto 1/2 mile in length hence 62 access points


partial mesh topology - i assume due to other sites using centralized citrix online site

fttb -  fibre to the business - i assume


i assume customer premises equipment on customer site

network topology:

3g wireless


a 4g topology already in place where users can  select it via their tablets but due to the specific types of problems experienced have decided against the 4g while users currently have now returned to their manual system while the development team collaborate on resolutions.

-  I would assume that the servers would be setup as: ou/group policies etc

-  62 wireless access points scattered inside/outside the yard which were obviously tested during the initial planning stages of the project which I think is using a 3g network.

-  windows 10 tablets used and then the users logon via a web browser to a citrix site in order to complete their daily routines via an online database that they also login to.

-  the advice given to users is if their are blind spots within the wireless for one reason or another then to walk around and continue to attempt to logon via their internet browser to access the (citrix) website where all works are carried out.

user windows 10 tablet network experience:

-  the first test of use was when it was not that busy and all things seemed to run smoothly ie when managers logged onto the citrix website and allocated bays via the software so a driver could park his empty truck or full truck on the bay, ready to be loaded/unloaded it appeared to work ok.

current issue:

-  as the night when on due to valentines I assume and the loading/unloading of parcels being delivered/collected and bought back to the depots, it appeared that there was loss of connectivity, such as:

-  loss of connection to network printers
-  trucks being allocated to bays that already had a truck parked in the bay ready to be loaded/unloaded

almost as if the citrix database could not deal with so many online tasks/sessions being processed through the citrix database website and as a result sessions causing back to front inconsistencies.

possible considerations:

- is the citrix site compatable for specific requirements
- is the spec of the citrix) site correct
- is the 'ou/group policies' configured correctly although I assume so
- I assume if (fttb) is in place this can obviously deal with the expected bandwidth requirements
- is the wireless robust enough due to 62 access points
- are the wireless win 10 tablets spec sufficient

question 1.  can anyone shed any light on possible resolution strategy  ?

i assume this was already done through the development team.
-  loss of connection to network printers

If the wireless infrastructure is overloaded ,you will have these types of issues.

If your servers are provisioned correctly.I can't see the DB being the bottleneck.
You could look at the server logs and see if you are having resource issues in the event viewer under applications.

Why they would use 3g as opposed to regular wireless AP's from folks like Ruckus or Aruba has me scratching my head.

Your mentioning the upgrade to 4g being roiled back suggests a the same.

I mentioned 3g but assumed so but they have physical access points so maybe not 3g.

the 4g  is only there apparantely if  apparently the weather knocked out the access points or whatever master access point has been put in place.

Currently the 4g is not being used & company using their manual system currently.
During those times of slowness and disconnects,somebody needs to be there to capture the network traffic.

Most of the big boys have software that can monitor the APs if they are having issues.

Depending upon the AP and network protocols (A,C,B,G,N),funny things can happen.

You can be in a room where an AP running N will be bypassed in favor of one down the hall.

If folks can duplicate the issues consistently ,you just do the old process by elimination routine.


understood well lets see what evolves from their decision making.


im sure its cisco type access points being used.


it appears as it turns out that there was bugs needed resolving within the software & apparently attempted to be fixed while live but did not appear to fix..

they have since updated & test updates & all appears improved so i will know if things have been fixed or improved by monday more than likely.


although bugs were fixed the server was changed also from a virtual due to also latency to a physical machine.

although problems are still being fixed it appears  things are going in right direction.

appreciated for advice!!


advice appreciated.
