As the name suggests, 5G is the fifth generation of cellular mobile communications.
The key benefits of 5G over 4G LTE are much higher data rates (1-20 Gbit/s), much lower latency (1 ms), and increased capacity as the network expands.
Higher data rates allow consumers to download content more quickly e.g.
a consumer could download a full HD movie in less than 10 seconds on a 5G network vs. ~ 10 minutes on a 4G network.
More broadly, the 5G network will advance mobile from largely a set of technologies connecting people-to-people and people-to-information to a unified connectivity fabric connecting everything to everything (X2X); 5G will act as a critical enabler for Massive IoT, Connected Autonomous Vehicles (CAV), remote critical control etc.
Understanding the vast amount of data generated from the 5G revolution intelligently will be a key challenge in unlocking the full potential of 5G to vastly improve our lives, as promised.
