A Workshop organized in conjunction with PIMRC 2013, 8-11 September, 2013, London UK

24th annual IEEE International Symposium on Personal, Indoor and Mobile Radio Communications

There is an increasing demand for mobile data (the data tsunami). The demand can be met by a combination of different strategies; improved technology (spectrum efficiency), allocation of more spectrum and use of smaller cells. When it comes to spectrum allocation, on one hand efforts are made to allocate “more” bands and on the other hand new techniques to exploit and “re-use” bands allocated for other application.

We believe that there is a “gap” in the discussions and understanding of spectrum usage for mobile broadband services. As we see it spectrum shortage also needs to be discussed in terms of trade-offs between capacity needs, spectrum and infrastructure cost.

We also would like to highlight the clash between business models that are applied by different actors, there seems to be a “great divide” within the industry where different deployment models have different spectrum demands. There are two ways to confront the mobile data tsunami:

  1. Traditional operators.
    Huge licensed spectrum demand to maintain inefficient wide-area (outdoor) deployment whilst majority of projected traffic is indoors.  Here we see lots of sites and towers, high wall penetration losses, high energy consumption. The current operator business model (“owning the subscriber”) is applied and protected.
  2. Indoor/Hotspot operators
    Here we can see a moderate spectrum demand above 3 GHz due to short range systems, very efficient reuse and where “light licensing” regimes, shared spectrum and secondary spectrum reuse are possible. This will require new cooperative business/roaming models since both infrastructure and spectrum most likely need to be shared.


Workshop Topics

Topics of interests for the workshop are:

  • Addressing mobile broadband capacity demand
  • Addressing identified spectrum scarcity cases
  • Estimating the spectrum use/efficiency of different bands
  • Spectrum sharing strategies and new paradigms
  • Using small cells and femtocells, outdoor/indoor aspects
  • Regulatory approaches including preparation for WRC-15
  • Trade-offs between capacity needs, spectrum and infrastructure cost
  • Techno-economic analysis of items above
  • Business model  aspects of sharing, offloading, and roaming
  • Energy-aware spectrum sharing solutions


Workshop Format

It will be a half a day interactive workshop, the program will include presentations by invited speakers as well as those accepted from the open call for papers and also a panel discussion.


Paper submissions and reviews

Paper submissions and reviews will be handled by use of EDAS, more details will come.
Each submitted paper will be reviewed by three reviewers.
The accepted papers will appear in IEEE Xplore

In order to speed up the review process contributors are asked to notify the organizing committee about the paper submission. This is done by registration of the paper in EDAS including title, authors, key words and abstract May 31. The schedule for papers submissions and reviews is:

Submission  of paper abstract: 31 May 2013
Submission of full paper:          16 June 2013
Notification of acceptance:         3 July 2013
Camera ready papers:             15 July 2013
