I hope you appreciate the fact that I’m sparing you a long diatribe on the technical aspects of your phone’s radio frequency usage. At best, an explanation would be wordy and confusing. And it’s unnecessary.

The simple explanation for those letters and numbers associated with your smartphone’s signal is this: The higher the number in the radio frequency designation, the faster the data signal can communicate with your phone. The G stands for the generation of the device. LTE stands for Long Term Evolution (basically, industry and marketing jargon), and 4G VoLTE means that you can make voice calls over the LTE data network.

Each leap in technology represents more signal capacity. The faster newer-generation technology also means less latency (lag time) between the signal source and your phone. It takes less time to get a signal response, which, in the case of 5G, can mean useful advances in personal medical devices, such as remote monitoring, and more. Also, if you live in a home with lots of people using the Internet simultaneously, the 5G signal has more capacity and will improve buffering (latency) for everyone sharing a single signal.

You don’t need to run out and upgrade your phone unless it’s so old that the carrier no longer supports it in the country where you reside. Just FYI: 2G is gone, and 3G is on its way out, too.
