Hey Trimble where is your answer to the Leica AP20 AutoPole ??

"Cell corrections work just fine with an external modem, which is still much less expensive than the bridge – it’s the exact same setup, just with the modem outside rather than inside the receiver head."

I've been doing this with my Javad system since 2016. I use a Verizon Jetpack at the base, and my phone as a WiFi hotspot at the rover. It works great.
