I guess , there seems to be no limit to how we can access to a 5G network , there seems to be no limit to how we can put all those machines(regardless whether it is a  PC/Desktop or a Laptop or a Tablet or an  Engineering Workstation) that do not have a  built-in 5G modem [ 1 2 3 4 ] , to access the 5G bandwagon , so , using      " a 5G USB Dongle that I  envisioned "    to do that , is one of the many ways how we can connect , for example, our Laptop to a 5G network and at the same time use that Laptop to make phone calls and reply phone calls just like a 5G smartphone .
