Legacy Radio Access Network, RAN, infrastructures provide coverage and capacity with a fixed allocation of baseband and radio resources. This static allocation of resources means that systematic over- provisioning is needed in order to meet peak demands at any time and location.
C-RAN (Cloud RAN) centralizes the baseband processing resources of multiple base stations at a single location. However, the majority of the total base station cost lies with the RF modules or radio resources. Therefore, a more comprehensive and impactful virtualization approach must also include the radio resources to significantly improve the efficiency and utilization of the deployed resources.
RF ROUTER® takes virtualization one step further by not only virtualizing the baseband processing resources, but the operators’ most valuable asset, RF spectrum.
RF ROUTER’s unique “end-to-end” digital RF signal processing and software configurability mobilizes wireless coverage and capacity. The base station signal is converted to digital, addressable packets allowing routing of radio capacity from any source to any destination point within the network – any-to-any connectivity. Irrespective of the underlying physical transport network – whether a star topology or a chain topology, a logical network is formed that enables RF signals to travel from any source to any destination point, enabling RAN Virtualization.
