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.
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.
If you can't reconnect to your WiFi until you reboot your Froyo device, Wifix (lite) will probably help you. Just click the "Reassign" button, and about 8 seconds later you will be reconnected to your WiFi. You can use "Reconnect" if it doesn't work for you. There is also a "Keep Connection" checkbox that prevents your WiFi connection from been deactivated.
