Samsung is currently researching 6G. Not too much is currently known on how fast 6G would be and how it would operate; however, 6G will probably operate in similar differences in magnitude as between 4G and 5G. Some think 6G may use MM waves on the radio spectrum and may be a decade away.

5G use cases can range from business and enterprise use to more casual consumer use. Some examples of how 5G can be used include the following:

streaming high-quality video;
communication among devices in an internet of things (IoT) environment;
more accurate location tracking;
fixed wireless services;
low-latency communication; and
better ability for real-time analytics.
In addition to improvements in speed, capacity and latency, 5G offers network management features -- among them network slicing, which enables mobile operators to create multiple virtual networks within a single physical 5G network. This capability will enable wireless network connections to support specific uses or business cases and could be sold on an as-a-service basis. A self-driving car, for example, could require a network slice that offers extremely fast, low-latency connections so a vehicle could navigate in real time. A home appliance, however, could be connected via a lower-power, slower connection because high performance is not crucial. IoT could use secure, data-only connectionsMany of the big carriers are working on building up their 5G networks now. This includes Verizon, AT&T and Sprint. Verizon is working on implementing MM wave, and T-Mobile is working on low- and midband 5G first.
