Ericsson Time-Critical Communications for 5G IoT

Time-Critical Communication is designed to resolve lags and interruptions in 5G mobile networks supporting internet of things use cases highly dependent on low latency and is based on the 3GPP-specified ultra-reliable low latency communication (URLLC).

Introduced in 3GPP release 15 to address the requirements of ITU-R M.2083, the underlying use case is support for dense sensor grids of IoT endpoints, especially for manufacturing, energy transmission, transportation and healthcare. 

With the need to support end-to-end latencies as low as 5 milliseconds, the delay budget for individual interfaces can be as low as 1 ms or less (140 microseconds). URLLC prioritizes traffic and optimizes connections for latency performance rather than bandwidth.
