Diverse wireless standards, designed for diverse traffic types, operate in the same wireless environment without coordination, often leading to interference and inefficient spectrum usage. Although C-RAN (Cloud/centralized RAN) is a promising architecture to achieve intra-operator network coordination, the architecture encounters challenge when low latency services and diverse access technologies are expected over non-fiber fronthaul. So, multi-standard multi-channel access point with low processing latency is preferred to be at the edge of network instead of central cloud. But, developing this kind of equipment is difficult as multiple radio chips and drivers have to be integrated and coordinated. In ORCA (Orchestration and Reconfiguration Control Architecture) project, a SDR architecture is developed on a single chip radio platform including hardware accelerators wrapped by unified software APIs, which offer the following capabilities: (1) concurrent data transmission over multiple virtual radios; (2) runtime composition and parametric control of radios; and (3) radio resource slicing, supporting independent operation of multiple standards in different bands, time slots or beams.
