Abstract: Generally, a combination of the following features are present to provide a centralization solution, in some embodiments: Latency compensation and auto-calibration of the delay between the PHY and the radio; Leveraging loopback in the radio (ORAN standard defined); Measurement based on air timing and/or RRH early/late feedbacks; and ability to understand routing changes and recalibrate latency compensation. In one embodiment, a method is provided for providing workload redundancy in a virtualized radio access network (RAN), comprising: distributing a baseband workload from a plurality of cells onto a first virtualized baseband unit (vBBU) at a centralized site; provisioning a second vBBU as a redundant vBBU for the plurality of cells; synchronizing state from the first vBBU to the second vBBU according to a first periodicity; performing failover from the first vBBU to the second vBBU at a first time; and adjusting an operating latency during the performed failover such that the plurality of cells continues operation without an interruption of service.

Abstract: High capacity, long range wireless communication link was ever needed. With the technology advancement and the requirement for higher data rates and limited latency requirements the existing solutions are providing partial and very limited solution. We propose new approach that provides the need in an efficient way and with the required properties to allow easy use and tuning as well as great robustness with link redundancy.
