Hello, I’m studying for my sec+ and net+ certs. I’m not sure this is covered in those exams, but I’m very curious on cellular technology. Talking about 4G LTE voice and sms data, the stuff we think of as “phone” services, are still just converted and passed to the TCP/IP stack same as the data connection? But it doesn’t become an IP packet until it makes it to the tower and is then converted? I’m having trouble finding good info about the process online. Thanks in advance guys!
