a) I'm using MKR GSM 1400
b) In an urban area in the US with good network coverage.
c) As SIM card I tested both Twilio and Hologram.
d) As antenna I am using this one https://www.robotshop.com/en/dipole-antenna-arduino.html
e) Code I used to test is: https://github.com/arduino-libraries/MKRGSM/blob/master/examples/GsmLocation/GsmLocation.ino
Issue & Question:
Unfortunately the latitude/longitude I'm getting is far off (about a mile off) from the actual location.
Is there anything I should do to improve the accuracy ? Maybe use different library than MKRGSM ? or keep the same library but use different function other than GSMLocation.latitude() GSMLocation.longitude() ?
Any hints or guidance is much apopreciated,
