“On behalf of the SATNAC 2008 Programme Committee, I am delighted to inform you that the following submission has been accepted to appear at the conference:
Mapping the Location of 2.4 GHz Transmitters to Achieve Optimal Usage of an IEEE 802.11 Network”

Cool! Another conference! Really nice reviews from them as well, this paper was based on similar work to the ISSA paper but it has been completely reworked. Now I must just do the reviewers changes and submit the camera-ready paper.

Still waiting to hear about my Research-in-Progress paper from SATNAC, will keep you posted!

I guess I can say that I am now published due to an interesting turn of events!

I posted before on how my paper was unfortunately not accepted, but I wasn’t too disappointed as I was still going to be attending the conference and I designed an A1 poster for the event. Anyway, two days before leaving Grahamstown I found out that my paper had been upgraded to presentation material and that I would be presenting in a Research-In-Progress slot instead! Cramming an entire years work into a 15 minute presentation time slot was rather difficult, but I think it went ok and I received some interesting comments. The audience seemed very interested.

I am published in the proceedings as well, however it is not my “camera-ready” paper, which I am fixing up now and will be mailing to them to put on their website instead of the pre-review paper.

I also have a very shiny poster which was never seen…

A full paper titled Mapping the Location of 2.4 GHz Transmitters to Achieve Optimal Usage of an IEEE 802.11 Network has been submitted to the Southern Africa Telecommunication Networks and Applications Conference (SATNAC) for 2008. This paper is based on the work I completed in my honours year.

I am finishing writing a second paper for SATNAC, a Work In Progress (WIP) paper which is more concise and based on the work I have completed so far in my Masters research. This needs to be submitted by 7th June.

Unfortunately my paper on Location and Mapping of 2.4 GHz Transmitters for the ISSA Conference 2008 was not accepted. But I will still be attending the conference and instead presenting a poster on my honours work.

So I will be heading to Johannesburg on the 6th July 2008 and I’ll be getting back to Grahamstown on the 10th July 2008.

Last year I completed my BSc Honours in Computer Science. My project was about discovering the locations of 2.4 GHz transceivers (like Wi-Fi devices) using multiple spectrum analysers (and the method of trilateration). The project was aptly titled IEEE 802.11 Signal Source Mapping using Low Cost Spectrum Analysers.

The project was rather successful and I developed a proof of concept application to demonstrate its uses. A small pamphlet (70 page thesis) was written discussing the finer points of the project :) For more details on the project see my honours research website.

The application produced some interesting results, and some really interesting signal maps. Each circle is displaying data from the application interfaced to the spectrum analyser, the circle radius is an estimate at how far a received signal has been transmitted from. Devices can be discovered by noting where the overlapping signals intersect.
