Providing Ultra-Reliable Low Latency Services for 5G with Unattended Datacenters

The strict requirements imposed by ultra-reliable low latency (uRLL) services in 5G can be costly for 5G network operators: low latency requires the deployment of distributed datacenters, while ultra-high reliability usually means attended datacenters. This paper checks whether it is possible to operate the datacenters hosting uRLL services without on-site support without affecting service availability. Overall, the paper shows that deploying additional redundant hardware and implementing uRLL services by exploiting these extra resources, the required availability levels can be maintained without on-site support, which may mean significant OPEX savings for 5G network operators planning country-wide coverage for uRLL services.
