Remote Programming

Hi. I have project for a commercial client where we have a B&W screen with logic and CBUS relays/DSI module etc.
Now because the site is not local, I am looking for a solution to enable remote programming of the CBUS and the Touchscreen.
One point to mention would be it is very unlikely that the client will allow us to use their internet connection, so was thinking of a GSM router solution.

So just seeing if anyone has any experience with this, and if there are any products used that would be recommended.

 

Would be more robust and reliable to have a dedicated DSL line with a CNI attached to that router.

Then you aren't giving connectivity to their infrastructure and you arent subject to coverage and bandwidth issues that plague mobile networks.

I used to do tech support for a major Telco's mobile data, I wouldn't want the hassle of doing this over a mobile connection.
