Abstract
A wireless access system includes a baseband processing unit pool, an optical network unit and a remote radio head. The BBU pool may be connected to one or more ONUs, each of the ONUs may be connected to one or more RRHs, and the connection between each of the ONUs and the one or more RRHs may be implemented using a twisted pair. Embodiments can provide access, convergence and transport with a very large capacity from indoor antenna units to a centralized BBU as well as an easy installation, and thus they are cost economical for a large scale deployment of indoor wireless access. Furthermore, advanced wireless technologies, such as large scale MIMO and CoMP, can be supported.
Claims9
A wireless access system, comprising:
- a baseband processing unit (BBU) pool,
- an optical network unit (ONU), and
- a set of remote radio heads, the BBU pool being connected to one or more ONUs, each of the ONUs being connected to at least two remote radio heads of the set of remote radio heads, a connection between each of the ONUs and each of the at least two remote radio heads being implemented using a twisted pair,
- wherein the BBU pool compensates for crosstalk in transmission via the twisted pair.
