wavemon is a ncurses-based monitor for wireless devices. It allows you to watch the signal and noise levels, packet statistics, device configuration, and network parameters of your wireless network hardware. It has currently only been tested with the Lucent Orinoco series of cards, although it should work (with varying features) with all devices supported by the wireless kernel extensions written by Jean Tourrilhes.
The Wifidog project is a captive portal solution that has three main functions: location-aware delivery of internal or external content, authentication and authorization, and centralized network monitoring. Most of the contributions to its development came from wireless community groups, so this is the model with the most support. However, Wifidog has an extremely generic design. As such, it is now used by several other types of organizations. With relatively small amount of development it can also be used for many other business models.
ePoint HotSpot is a firmware for wireless routers based on OpenWRT with some ePointy extensions and an ePoint-branded UI theme. It is distributed as a stand-alone flashable firmware-image, as a set of extension packages for OpenWRT, pre-installed on wireless routers, and in source code. It is aimed primarily at catering businesses, Internet cafés, and medium-sized communities (e.g. residential co-ops) wishing to share their Internet connection on a fair basis. The primary target hardware is WRT54GL by Linksys.
YFi Hotspot Manager is a modern AJAX Web front-end for FreeRADIUS 2.x. It has support for vouchers, permanent users, billing post paid, and pre-paid. Multiple languages are supported. Statistics can be generated. It works with CoovaChilli and Mikrotik. It runs on Ubuntu and CentOS. It has Google Maps integration. Third party systems can be integrated. There is thorough documentation.
linux_ics is designed to make the process of sharing an Internet connection from a Linux computer easier for the average user. It handles configuring the interfaces, setting up NAT, and optionally running a DHCP server. In addition to Ethernet, linux_ics can also share an Internet connection over a WiFi interface in either ad-hoc or master mode.
ribbil is a wireless network manager designed for power users. It purposes is to provide an easy way to connect to wireless networks from a console under GNU/Linux, using wpa_supplicant and wireless tools. It can be used through the command line directly or through its curses interface.
Mole (Mobile Organic Localization Engine) provides room-level geoposition estimates using existing WiFi infrastructure. When you create an entry in the database by naming a room, your and other users' mobile devices will recognize when they are in that room. Other applications can poll or monitor the current room estimate and act accordingly, with context aware behavior. Because too much WiFi scanning drains batteries, it uses accelerometers and other tricks to keep scanning to a minimum while keeping update latency reasonable.
NetSpot is a simple and accessible wireless survey tool. It allows you to collect, visualize, and analyze Wi-Fi data using any MacBook. NetSpot can visualize your wireless network by building a visual Wi-Fi map. It will let you see dead zones without coverage and place hotspots (access points) correctly. Using the visualized map of collected wireless data, you will also see channels' load and will be able to decide how to optimize your Wi-Fi site better. NetSpot is a powerful analyzer of Wi-Fi coverage. It will gather all the information needed for analyzing radio signal leakages, for discovering noise sources, for locating effective access points, etc. You can also use NetSpot as a powerful wireless network planning tool.
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.
