It has been projected that next generation cellular base stations will have uplink speeds around 10Gbps or more, serving 6 or more sectors with channel bandwidths beyond 200MHz. The anticipated cellular network architectures that include a very large number (>100) of antennas per sector drive the strong demand for an increased uplink channel capacity. Today's platforms cannot scale to meet these requirements. A networked solution is required to enable:
Ethernet technology has demonstrated steady, cost efficient speed and capacity growth driven by the enterprise connectivity, access, and data-center markets. The Radio over Ethernet (RoE) project aims to take advantage of the Ethernet developments and specify a scalable and streamlined solution that complements, for example, the existing CPRI radio transport specification based on fixed time division-multiplexing.
The P1904.3 standard will enable the transfer of In-phase Quadrature (IQ) user-plane data, vendor specific data, and control and management (C&M) information channels across an Ethernet-based packet-switched network. The standard will foster interoperability among implementations by defining framing, the encapsulation of the information, and a common Ethernet Type for Radio over Ethernet (RoE) purposes.
This standard will specify:
