So here’s a question that’s not likely asked often. I’m testing the Boron LTE and having good results with it so far. I use a third party SIM from Hologram since my customers often live in areas of the US that AT&T doesn’t reach reliably. So far I have the Boron successfully connecting to both Verizon and AT&T, and it even seems to be automatically selecting the carrier. That’s great!
BUT. My last batch of prototypes (not using Particle hardware) were supposed to intelligently switch between the two carriers also. I found out it wasn’t so intelligent and ended up with devices stuck in endless connection loops trying to connect to a carrier that it simply couldn’t reach.
For testing purposes, I’d like to simulate some of the conditions I actually see in the field, like carrier dead zones. I have locations where AT&T is either unavailable or has extremely low signal, but Verizon works fine. My question is, does anyone have ideas on how to simulate this environment in the lab? i.e. One carrier is accessible, but the other is not. I can put some money towards a simulation environment, but I don’t exactly have a big budget. Is there a decent way to for instance, block carrier X or degrade its signal, on a very localized scale? What I am envisioning and may be completely off base with, is being able to jam a particular carrier’s signal, just within my lab, so I can see how the device performs.
Does anyone have any creative ideas?
