5G is the fifth generation of mobile data technology. Designed to increase speed, reduce latency, and improve wireless service resiliency. In theory, 5G technology can reach speeds as fast as 20 Gbps, while 4G's top speed is only 1 Gbps. 5G also has less latency, improving the performance of business applications and other digital experiences such as online gaming, video conferencing, and self-driving car performance.
