4G has all the features of 3G at more speed. It provides download speeds of around 14 Mbps up to speeds as high as 150 Mbps, five times faster than 3G. And it allows more than ten times the uploading data speeds of 3G, ranging from 8Mbps up to 50 Mbps.
Low latency is another feature, it ranges from 60ms to 98 ms, Although it’s only a few milliseconds lower than 3G, it is very necessary for some use cases like video conferencing or online gaming, and other live interactions.
The rise of VoLTE standard added another feature to 4g technology which is the ability to make phone calls and surf the internet at the same time, with even enhanced voice quality. All of these advantages are within your reach with Oppo A77 (2017) 4G technology.
