1. A distributed antenna system (DAS) architecture, the DAS architecture comprising:
a DAS cloud computing network;
a first distributed antenna system comprising uplink circuitry and downlink circuitry configured to implement at least a first user plane, wherein the uplink circuitry forwards uplink radio frequency traffic from at least one remote antenna unit of the first distributed antenna system to at least one master unit of the first distributed antenna system, wherein the downlink circuitry forwards downlink radio frequency traffic from the least one master unit to the at least one remote antenna unit;
wherein the DAS cloud computing network comprises a control plane in communication with the first user plane of the first distributed antenna system through a network;
wherein the first user plane comprises a protocol interface abstraction layer coupled to the network and is communicatively coupled to the control plane through the network by the protocol interface abstraction layer of the first user plane, wherein a protocol interface abstraction layer translates configuration commands received from the control plane into DAS hardware specific instructions compatible with the uplink circuitry and downlink circuitry, and wherein the first user plane processes and forwards the uplink and downlink radio frequency traffic based on configuration commands received from the control plane via the protocol interface abstraction layer.
