Small Cells Research Bible

Here is a detailed research on Small Cells from Mehdi Bennis and Walid Saad presented in IEEE Dyspan 2014, this month. Feel free to add any comments for questions you may have.

AT&T: Small Cells advertisement and Cell On Wheels (COW)

Interesting Small Cells advert from AT&T:

In the recent Boston marathon on the weekend, they also used their COW (Cell on Wheels) to boost the service. Here is a picture from their official tweet account. To know more, check their tweet out below.

You can also see whats inside the COWs in the video below:

Unlocking Small Cells for the Enterprise - EE

Another excellent presentation by the UK operator EE in our Cambridge Wireless SIG. There was a discussion about the different options during deployment, which options are more preferable than others, etc.

Another point worth mentioning is the potential of Small Cells in emergency and disaster situations. We have seen similar deployments happening in Japan during the tsunami that occurred a few years back. The complete presentations as follows:

Operator plans for the ultra-dense network

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:
