The following is from Rethink Wireless article last month:
Large-scale deployments of public access small cells are still in their infancy, but there is already talk of 'hyper-dense' networks to cope with hotspots of intense data usage. Most of this remains just talk, but Qualcomm - on the rampage in metrocells after a hesitant start- is showing off how the approach might work in reality.
The chip giant, never averse to a bold demonstration, is claiming the densest network ever constructed in a working environment, equating to 1,000 cells per square kilometer (a neat figure given that Qualcomm's ongoing marketing campaign revolves around the '1,000x Data Challenge', predicting an increase of that magnitude over the coming decade).
It has put the trial together for Sprint's TDD technology, working with Airspan, the WiMAX specialist that has evolved into a small cell vendor with heavy emphasis on self-organization and integrated backhaul.
We recently heard from Caroline Gabriel in our Cambridge Wireless Small Cells SIG this (last) week. This very interesting presentation below is from that event. A very important slide is the tools that are available for achieving this ultra-dense networks. Anyway, presentation as follows:
