WiFiDB is a set of scripts that is intended to manage wireless access points found with the Vistumbler wireless scanning software. WiFiDB also has support for importing Netsumlber summary files and Wardrive for Android database files. WiFiDB can also export access points with GPS to a Google Earth KML file, so you can see where the access points are located.
OsmoSGSN (Serving GPRS Support Node) is the central core network node of a GPRS/EDGE/UMTS cellular network. It is an experimental SGSN implementation, exposing a Gb interface (NS/BSSGP) towards the BSS and the GTP protocol towards the GGSN. It is not yet ready for production use, but primarily for laboratory and research use.
SIMtrace sniffs communication between a mobile phone and a SIM/USIM card. This can be useful for research and analysis, and for developing mobile phone and SIM toolkit (STK) software. The SIMtrace hardware is also capable of MITM (man in the middle) attacks on the SIM-MS communication.
wwan-helper is a script that establishes a UMTS connection using a Ericsson F3507g Mobile Broadband Module. It was designed to be used with a ThinkPad T420s. It takes care of resetting and reinitializing the modem if the hardware fails to get a WWAN connection, and retries as often as necessary until the UMTS connection is really established. It is meant to run as a hook script for the ifup / ifdown mechanism, but should also work on other networking systems.
Xiwtool simplifies connecting a Linux computer's wireless card to a nearby Wireless Access Point. It allows anyone to browse nearby networks and can help you configure a Linux machine to connect to a WAP. It is compatible with any Linux system with a graphical desktop and wireless card, and can configure wireless connections on most systems which use ifup and ifdown to connect to the Internet.
Bluelog is a Bluetooth site survey tool, designed to tell you how many discoverable devices there are in an area as quickly as possible. Bluelog differs from most Bluetooth scanners in that it prioritizes speed of reporting over anything else (i.e. it doesn't spend time trying to pull detailed data from a device) and doesn't require any user intervention to function. As the name implies, its primary function is to log discovered devices to file rather than to be used interactively. Bluelog could run on a system unattended for long periods of time to collect data. In addition to basic scanning, Bluelog also has a unique feature called "Bluelog Live", which puts results in a constantly updating Web page which you can serve with your HTTP daemon of choice.
Jkaptive is a simple captive portal without RADIUS (and thus without total security, but at the same time without too much hassle). The reason behind this is because a lot of site administrators don't need tight security; their site is just a café that offers free Internet access on an unsecured WLAN access point connected to the Internet, and they need a ticketing system to make it cumbersome for average people to use this offering without actually buying a single coffee. Jkaptive itself just presents the login page and checks the token. The blocking of unticketed traffic is done through Linux' netfilter. As no proxy server is involved, jkaptive has no performance penalty, nor does it create problems with non-HTTP traffic. Once the token is accepted, jkaptive is out of the way of any network packets completely. For presenting the login page, jkaptive has a built-in Web server, so no additional Web server application is needed.
