Cyberspectrum #6: San Francisco

We're back at Noisebridge in San Francisco!

IRC chat will be on Freenode #cyberspectrum

We have two great speakers:

• Harvind Samra (CTO and Co-Founder of Range Networks):
"OpenBTS: A Software-Defined Mobile Network"

The OpenBTS software is a Linux application that uses a software-defined radio to present a standard 3GPP air interface to user devices, while simultaneously presenting those devices as SIP endpoints to the Internet. This forms the basis of a new type of wireless network which promises to expand coverage to unserved and underserved markets while unleashing a platform for telecom innovation.

• Jason Abele:
"Software Defined Radio without the Radio, using GNU Radio and a sound card to develop a receiver for atomic time from WWVB"

We will talk a little about DIY VLF/LF antennas, the history of WWVB and atomic clocks, and demonstrate how to use GNU Radio to turn a cheap SDR rig into a very expensive clock.
