Slicing uses the virtualized 5G core to create logically separate networks on shared radio and transport infrastructure. One slice might guarantee low latency and high reliability for a robot fleet, another might prioritize throughput for video, and a third might be tuned for massive numbers of low-power meters. Each comes with its own quality parameters and can be isolated from the others.
For IoT buyers the promise is an operator-provided network that behaves like a private 5G deployment without owning the equipment, backed by a contractual SLA per slice. The caveat is that end-to-end slicing requires a standalone 5G core and support across the radio, transport and core layers, which operators have rolled out unevenly. Many current offers are closer to prioritized traffic classes than to fully isolated networks.
