Automated 4G / 5G HetNet Design


I recently heard Iris Barcia, COO of Keima speak after nearly 6 years at Cambridge Wireless CWTEC 2018. The last time I heard her, it was part of CW Small Cells SIG, where I used to be a SIG (special interest group) champion. Over the last 6 years, the network planning needs have changed from planning for coverage to planning for capacity from the beginning. This particular point started a little debate that I will cover in another post, but you can sneak a peek here 😉.

Embedded below is the video and presentation. The slides can be downloaded from SlideShare.

Radio Challenges and Opportunities for Large Scale Small Cell Deployments

Here is another presentation by Keima at our Small Cells Event. Their last presentation on "Twitter et al. for Small Cell Planning" was a hit and has racked up over 9000 views on slideshare.

Summary of Cambridge Wireless Event on Small Cells, 3rd Oct. 2012



We had another successful Small Cells SIG Event (jointly powered by the Radio Technology SIG) in Cambridge Wireless on the theme “Radio Challenges and Opportunities for Large Scale Small Cell Deployments”. I will be looking at the presentations in detail in separate blog posts as there are interesting bits and pieces from each of them that can easily be overlooked. Here is a high level summary of this event.






We had over a hundred delegates in this event and as one of the speakers admitted privately, they were expecting to see around a dozen people and were a bit overwhelmed by the number and caliber of the people. The delegates included small cell vendors, chipset vendors, test & measurement vendors, operators, industry analysts, regulators, etc. It was a lovely day to be in Cambridge with the sun shining the whole of morning and the afternoon to show us the best of the Downing college.


The event was kicked off by Prof. Simon Saunders, formerly the founding chairman of Small Cell Forum who talked about the long journey the small cells (or Femtocells as they were then known) have gone through, the benefits and the road ahead.


This was followed by a talk from Julius Robson of CBNL, who was also representing NGMN. The focus of the talk was on backhaul.



Nick Johnson, CTO of ip.access was the next speaker who started his presentation with humorous note. His presentation was titled "Building the World’s Largest Residential Small-Cell network" but as he said he was very tempted to change the title to “How to Screw Up the World’s Largest Residential Small Cell Deployment”. His talk had lots of real life examples on where and how things can go wrong and how to make sure they dont. If they do, what lessons should be learnt. Some of these problems have been faced by me too in various test scenarios. It was a very interesting talk.


After the break we heard a presentation from Steve Brown of Telefonica O2 UK. The talk was a bit familiar for me (and my blog readers) as I have already blogged on similar information in the past. It was though new information for the audience and could see that they were enjoying this information. A lot of questions were asked after the presentation and also in the panel discussion at the end. There is some interesting new information that I will blog later on.



The final talk was by Iris Barcia of Keima who talked about "Small Cell Network Design".

Finally we had a panel discussion with lots of interesting questions. Once the discussions finished there were people discussing and debating issues among themselves for a long time. I am looking forward to the next event in January in London on the topic "Lets get real!" where we are hoping to be able to hear from some more operators/vendors on the deployment and rollout issues. More details available on the Cambridge Wireless page here.

Twitter et al. for Small Cell Planning

A recent report in Light Reading mentioned about using Twitter for planning of Small Cells network. In fact for quite a while, a UK based company, Keima has been using this technique to help plan small cells deployments in the US. I used some of their research in my presentation in the Optimisation conference; see here.

A map using the Keima tool showing the activity on the Social Networks for London is as follows.



It would be very interesting to see the above during olympics.

If you are interested in learning more about the tool see Keima's presentation from MWC here and their video here.

Keima’s Simon Chapman will be presenting to the Cambridge Wireless Small Cells SIG event on 3rd October on the topic "Deploying bigger numbers of smaller cells". Here is a summary of things going to be discussed by them:



We discuss how "small cells" are a natural evolution of network design principles started with A.H. Ring in 1947. We discuss the practical consequences of managing interference while rolling out more cells in the next few years than all the previous deployments put together.

We consider processes for achieving cost-effective, spectrally efficient network capacity and establish the most influential: the location of small cells. Given the importance of location we demonstrate mechanisms for identifying demand hotspots using publicly available datasets and show that this knowledge alone has a significant impact on the eventual network capacity.

Finally, as we look at the immediate areas in and around demand hotspots, we discuss the associated issues of selecting thousands of utility poles or building-side mountings; of managing wired or wireless backhauling; of lowering latency; of repurposing the macro
