April Meeting report (for John A)- Next meet, Station May 25th.

24 05 2010

April meeting has turned out to be a “communications rich” event circling around VOIP in it’s many guises. Discussion of the open source GSM core network on an island called Niue was very interesting and was propably most people’s first introduction to OpenBTS and GNU Radio.

Jon gave a very good description of how he customized open source software to give a professional integrated solution used by a local VOIP provider.

More practically any user can get into this technology using live disks which are available both for Asterisk and for OpenBTS(check links out).

Usual talk abounded about “When I was young…..” or rather what was my first experience of computing. PDP 8 clone kits from Sparetime Gizmos seemed to fit the bill as suitable flashy light subsitutes for the real thing!!!

The next meeting is on Tuesday 25th May at the Station Inn:
