Things and Stuff Wiki - An organically evolving personal wiki knowledge base. An on-the-fly taxonomy containing a patchwork trail of topic outlines, descriptions, notes, stubs and breadcrumbs, with links to sites, systems, software, manuals, organisations, people, articles, guides, slides, papers, books, comments, videos, screencasts, webcasts, scratchpads and more. Content is orientated towards mostly free/libre/open, mostly Linux. Quality and age varies drastically. Sometimes old things are first, sometimes last. Use the Table of Contents menu to navigate long pages. Zoom in if text is too small. Dead link? Wayback Machine. I probably need to fix the theme CSS after an update. See also libreav.org.

RTL chipset

http://sdr.osmocom.org/trac/wiki/rtl-sdr - RTL-SDR is a set of tools that enables DVB-T USB dongles based on the Realtek RTL2832U chipset to be used as cheap software defined radios, given that the chip allows transferring raw I/Q samples from the tuner straight to the host device.

http://www.hamradioscience.com/rtl2832u-r820t-vs-rtl2832u-e4000/

The frequency range of the RTL2832U / E4000 is generally around 64MHZ to 1700MHz with a gap around 1100MHz to 1250MHz. The RTL2832U / R820T frequency range is 24MHZ to roughly 1850MHz with no gaps (found yet), and no DC offset spike.

RTL dongles have 2.4 MHz of useful bandwidth.

Telephony

http://openbts.org/
- - OpenBTS is a Unix application that uses a software radio to present a GSM air interface to standard 2G GSM handset and uses a SIP softswitch or PBX to connect calls. (You might even say that OpenBTS is a simplified form of IMS that works with 2G feature-phone handsets.) The combination of the global-standard GSM air interface with low-cost VoIP backhaul forms the basis of a new type of cellular network that can be deployed and operated at substantially lower cost than existing technologies in many applications, including rural cellular deployments and private cellular networks in remote areas.
