The paper titled ”When Cellular Meets WiFi in Wireless Small Cell Networks” was listed among ten most popular articles published in ComSoc periodicals in June 2013, based on PDF views trough IEEE Xplorer.

The main author, Dr. Mehdi Bennis, works as a Research Manager at the University of Oulu Centre for Wireless Communications (CWC).

The topic of the paper, traffic offloading, is one of the hottest research problems in communications engineering right now.
-With the advent of small cells the challenge is to solve the problem of traffic offloading in an intelligent manner and with very minimal overhead and signalling. The concept described in the article is based on reinforcement learning, in which small cell base stations learn on their own how to do load balancing between LTE spectrum and WIFI, Bennis explains.

For the CWC, the rating is good news in terms of positioning the research centre in the field.
-Popularity of the article can be seen as an indication of the fact, that we are in the forefront of the research in small cells and 5G networks in general, the author rejoices.
