New 6G networks might see early commercial deployment by 2028 or 2029, ABI Research forecasts, with significant portions of the standard set as early as 2026. As always, performance metrics will improve by an order of magnitude to two orders of magnitude.
That is likely to be the case for peak data rates, latency, spectral efficiency, ability to use any available capacity and device density. Support for devices with long battery life is likely to be built in as well.
As was the case for 5G, new use cases will drive some standards goals.
As 5G was designed for machine-to-machine use cases, 6G might be designed to support various forms of extended reality (augmented, virtual, mixed).
As was the case for 5G, 6G also will likely include measures to reduce network deployment costs and time to deploy, incorporating greater ability to use any available capacity.
About all we can confidently predict is that 6G will feature faster speeds, lower latency and use of higher frequencies. Whether speeds are an order of magnitude faster or two orders of magnitude is not yet clear.
Where 5G is designed to provide a peak data rate of 20 Gigabit per second (Gbps), and an average user experience rate of 120 Megabit per second (Mbps), 6G might be designed for 1,000 Gbps peak data rates and 1 Gbps average end user experience.
The expectation of new frequency allocations is based on history. Every next-generation mobile network has been based on new frequency allocations, higher in the radio spectrum, likely extending to teraHertz ranges.
And as 5G latency performance has moved closer to zero, we might be forced to consider concepts such as negative latency, such as the ability of the network to anticipate demand in advance, prevent issues in advance or eliminate signaling, computation or data transport.
The concept might be likened to the notion of prevention rather than cure: the ability to avoid computation or bandwidth operations because a potential problem is diagnosed and prevented from happening.
Architecturally, cell-less operation might be defined, allowing any device to connect with multiple radio access points simultaneously.
