That looks about right. Whats funny is that after having Sensorly on my phone for months, I just uninstalled it last week after never seeing any results for my area. Maybe I need to reinstall itSo I tried to test the 4g signal while driving, and these were my results. Pretty fast, especially considering the fact I'm in a moving vehicle. (according to the maps in Sensorly.com)
I highlighted the area of the parkway where I get the 4g signal. Towards the left of the picture is the signal for the area of Towota.
