I am planning an installation in an area serviced only by Verizon 3G wireless service. I would like to use a Pepwave MAX BR1 for connectivity. Since it is only going to be a 3G connection, I was wondering if I should use the 3G or the 4G version for best connection. I am not interested in the cost savings. I am only interested in best performance. I understand there are sometimes issues with 4G routers working well in 3G areas. I was wondering if anyone had any insight into this. TIA.
