I am trying to learn how my daughter who lives in North San Juan, California can get cell phone reception at her home. About 1/4 mile from the house on the paved road, there is 3g reception. Also, there are six single antennas within 4 mile of her house.
If she has ATT service and high speed internet, look into a 3G Microcell from ATT. I have 2, one and home and one at work, and they work great for me. Others have mixed results.
If she has high speed internet , she can request a femtocell from her cellular carrier . Otherwise - her only solution would be a wireless cellular amplifier system.
