Abstract
Disclosed herein is an architecture for a Digital Capacity Centric Distributed Antenna System (DCC-DAS) that dynamically manages and distributes resources in different locations where there is demand for capacity. The DCC-DAS also allows for the routing of resources to other applications such as location finding devices, jamming devices, repeaters, etc.
Claims12
A digital routing hub for coupling a plurality of base transceiver station (BTS) ports and a plurality of remote radio units (RRUs), the digital routing hub comprising:
- a digital processor for routing and processing cell resources data samples from the plurality of RRUs to the plurality of BTS ports;
- wherein, in an uplink direction, each RRU:
- receives one or more uplink radio frequency (RF) signals,
- digitizes the one or more uplink RF signals,
- filters the digitized one or more uplink RF signals on a cell resource basis to produce digitized uplink cell resource data samples, and
- wherein the digital processor:
- receives the digitized uplink cell resource data samples from the plurality of RRUs and
- allocates an individual routing path to the digitized uplink cell resources data samples;
- routes the digitized uplink cell resources data samples to two or more BTS ports using the allocated individual routing path,
- wherein the individual routing path is according to software programmable routines in the digital routing hub,
- sums a plurality of the digitized uplink cell resources data samples into a combined uplink cell resource data sample;
- assigns a routing path to the combined uplink cell resource data sample;
- and
- routes the combined uplink cell resource data sample to a BTS port according to the routing path;
- and
- a gain and routing management system,
- wherein the gain and routing management system individually controls a gain of one or more uplink cell resource data samples prior to the summation of the uplink cell resource data samples into the combined uplink cell resource data sample.
A digital routing hub for coupling a plurality of base transceiver station (BTS) ports and a plurality of remote radio units (RRUs) comprising:
- a digital processor that receives a plurality of digitized individual cell resource data samples from the plurality of RRUs;
- wherein the digital routing hub is interfaced with at least two BTS ports in a digital format and at least one RRU in a digital format, and
- wherein the digital processor:
- allocates an individual routing path to at least one of the digitized individual cell resource data samples according to software programmable routines in the digital routing hub,
- sums a plurality of the digitzed individual cell resource data samples into a combined uplink cell resource data sample;
- assigns a routing path to the combined uplink cell resource data sample;
- and
- routes the combined uplink cell resource data sample to a BTS port according to the routing path;
- and
- a gain and routing management system,
- wherein the gain and routing management system individually controls a gain of one or more the digitzed individual cell resource data samples prior to the summation of the digitzed individual cell resource data samples into the combined uplink cell resource data sample.
