Daniel Appelquist, who describes himself as an “open web advocate”, joins us to talk about TLS on the web: some good reasons for using it and the common objections to it. As someone with a very wide experience in IP and network communications, a session with Dan and our VUC regulars should be excellent!
From Ivelin Ivanov: In this session we will demo a full open source based mobile network running in an office setting. From Android mobile devices to OpenBTS base station from Range Networks and Restcomm app server from Telestax.
I have an OpenBTS dev kit base station running Restcomm and two Android devices connected to my miniature mobile network. The mobile devices can call each other and send SMS between each other. They can also call customer service IVR, conference bridge and other services implemented as Restcomm apps.
This demo shows that a commercial grade end-to-end 2G mobile network is possible today with open source elements. The demo setup can be easily expanded to life size mobile network. The OpenBTS dev kit box can be replaced with production OpenBTS stations with powerful antennas (10+km radius) and a cluster of Restcomm instances running in the cloud.
Overlaying an area of OpenBTS 2G base stations with a mesh of WiFi hot spots presents a plausible interim alternative to prohibitively expensive and still limited in many ways 4G networks.
This type of systems are particularly appealing for person to person and IoT communications in rural areas, remote work sites such as oil rigs, manufacturing, transportation, warehousing, telemetrics, and telemedicine scenarios.
After first experimenting with VoIP in 2004, Michael Iedema worked on IMS proof-of-concept projects until 2007, when he founded the AskoziaPBX project, an easy-to-use telephony system now deployed in countries around the world. After moving on in 2011 to do VoIP related research and development for Ubiquiti Networks, Michael is currently a Senior Engineer at Range Networks, the creators of OpenBTS.
The book Getting Started with OpenBTS is currently available for free download courtesy of Range Networks. Here is O’Reilly’s description blurb:
“Deploy your own private mobile network with OpenBTS, the open source software project that converts between the GSM and UMTS wireless radio interface and open IP protocols. With this hands-on, step-by-step guide, you’ll learn how to use OpenBTS to construct simple, flexible, and inexpensive mobile networks with software.”
VUC regulars assemble to ring in the year and diminish the hangovers of 2014. The video will be via Jitsi Video Bridge, with audio available live onhttp://vuc.audio. Connect via SIP for wideband audio at sip:firstname.lastname@example.org
Topics covered include Skype “Killers” like Wire.com, SS7 insecurity and hacking, microphones and much more.
Audio-only this week for an extended (2 hours) discussion of the past year, from WebRTC to the recent SS7 security scare. Many Internet topics were covered in this session (and a few unrelated ones like how to buy wine) that brought together Andy Abramson, Marc Abrams, James Body, Jay Carpenter, Karl Fife, Emil Ivov, Tim Panton and […]
