Hi to everyone. I am new to this group...80 years old so bear with me...I now have and use a verizon AC563 3g hotspot and it works fine...we now have 4g available and I am considering going to the novatel MiFi 4510L moble hotspot...I will and now only use will be in the house. question 1. what is the frequency of the 4G and the 3G? 2. will 4G penetrate a building as good or better than 3G? 3. does verizon have a external antenna for the Novatel MiFI 4510L that is placed outside the house and run into the device inside the house? and if so has anyone had experience with it? 4. for the home phone system that verizon has does anyone know if they have a antenna that is on the outside of the house running to the device inside the home? thanks in advance for your help...
