What's URLLC in 5G

URLLC stands for Ultra-Reliable Low-Latency Communications, which is one of the three main use cases for 5G wireless technology. URLLC is designed to provide extremely reliable and low-latency connectivity for mission-critical applications such as autonomous vehicles, industrial automation, and remote surgery.

URLLC builds on the capabilities of existing cellular networks and provides significant improvements in terms of reliability, latency, and network performance. With URLLC, users can expect to see network latency as low as one millisecond, which is several times faster than what is currently available with 4G LTE networks. In addition, URLLC networks will be able to provide extremely high reliability, with packet error rates as low as 1 in 10^9.

To achieve these improvements, URLLC networks use a range of advanced technologies including time-critical scheduling, high-precision clock synchronization, and edge computing (MEC or Multi-Access Edge Computing - a network architecture that allows computing, network, and mobile service providers to shift some of the computing and cloud-based processes to the edge of the network environment, achieving better performance, latency, and security). These technologies help to ensure that data is transmitted quickly and reliably, with minimal delay or packet loss.

Overall, URLLC is a key use case for 5G wireless technology and will enable a new generation of mission-critical applications and services that require extremely high reliability and low latency connectivity.
