Hi ! I bought the entire Raspberry Pi 4G/LTE Shield Kit and am using the LTE Main & Diversity Dual u.FL Antenna – 100mm instead of the one provided. I connected it to my main raspberry pi and it works but I was wondering if I want to use it as a hotspot for other raspberry pis to connect to what is the distance/range of connectivity this shield + antenna can provide ? I am using a AT&T sim card. Thank you.
