Artificial Intelligence in Network Optimization

One clear trend in wireless is the increasing level of network complexity and the corresponding rise in operating expenses. Networks support three or four technologies (e.g. GSM, 3G, LTE, Wi-Fi). A proliferation of frequency bands ranging between 600 MHz and 3500 MHz lead to different service performance. There are many different types of base stations such as macro cells and… Read More »

SON Progress Report: A Lot Still to Be Done!

Since the first building blocks of SON were laid down around 2008 by 3GPP and NGMN, uptake in SON deployments has been very selective by a few leading carriers for some use cases. However, universal applicability remains elusive. To say the least, the SON market is struggling – but why, and how that can be turned around is… Read More »

A Quick Tour of SON Basics

If operators are really serious about HetNets, then network operations cannot remain as usual. Deploying hundreds if not thousands of small cells is an operational nightmare that cannot be left to manual processes which is what operators do today. Automation becomes critical – and it has a name in wireless network: self-organizing networks (SON). So let’s take a… Read More »

SON Load Balancing and the Success of Disruptive Ideas

Thirteen years ago we were working at Metawave to address the capacity challenge operators were facing (sounds familiar?). Our solution was an adaptive system that automatically adjust the antenna beamwidth to change the coverage area of a given sector according to the traffic load. By changing the antenna patterns, and consequently the coverage footprint, it is possible to… Read More »

Small Cell World Summit 2013: Wireless Analytics to the Forefront

The Small Cell World Summit just concluded, so I would like to summarize my thoughts and impressions from this event. For a little perspective, the conference is sponsored by the Small Cell Forum, which was called the Femto Forum before it rebranded in February 2012. In alignment with this new vision, the 2013 edition of this conference featured… Read More »
