We face a growing challenge to the design, deployment and management of wireless networks that largely stems from the need to operate in an increasingly spectrum-sparse environment, the need for greater concurrency among devices and the need for greater coordination between heterogenous wireless protocols.
Unfortunately, our current wireless networks lack interoperability, are deployed with fixxed functions, and omit easy programmability and extensibility from their key design requirements.
Studied here is the design of next-generation wireless networks and an analysis of the individual components required to build such an infrastructure. Re-designing the wireless architecture must be undertaken carefully to balance new and coordinated multipoint (CoMP) techniques with the backward compatiblity necessary to support the large number of existing devices.
These next-generation wireless networks will be predominantly software- defined and will have three components:
(a) a wireless component that consists of software-defined radio resource units (RRUs) or access points (APs);
(b) a software-defined backhaul control plane that manages the transfer of RF data between the RRUs and the centralized processing resource; and
(c) a centralized datacenter/cloud compute resource that processes RF signal data from all attached RRUs.
