I am doing some research on cellular connections like HSPA. I have been searching for a Windows 8.1 API that will allow me to request the radio to use HSPA instead of LTE.
I have written an app for a window 8 phone and a windows 8.1 tablet. My area uses LTE, but I was able to disable the phone's LTE so it fell back to HSPA+. Unfortunately, I cannot find anything similar for this tablet (Nokia Lumia 2520).
So, I haven't found anything and I am beginning to doubt that I will, but I thought I would check with others before declaring defeat.
