OpenWLANMap@Android - collect data automaticallySimilar to SETI@home now there exists a possibility to support the OpenWLANMap project easily and fully automatically. To do that nothing more has to be done than to install a small App on your own smartphone or tablet. Once it was executed it runs in background and collects data that are useful for extending the projects database and uploads them from time to time. The user itself is credited by points that can be used to show its ranking comparing to other uses that do the same.
But how's that working in detail? The steps you have to do are quite simple:
You will get one to five points for every WLAN network that is new for the database or for every existing WLAN that has changed its position nameably so that it has to be added to the database again. The exact number of points depends on the measurement quality of that network. WLAN network positions that are already stored in database are used to increase accuracy.
How it works: this App uses GPS to find your current geographic position. In case there is no signal available (may be because you are inside a building or because you currently don't have a GPS fix), OpenWLANMap is used to evaluate your position. This second method of positioning is not available in case network access is not allowed since it requires an Internet connection. That means in this case it might be possible you collect less WLAN-points because you depend on the GPS-based positioning.
The OpenWLANMap@Android-App itself works as ressource-saving as possible. So it wakes up after some seconds to collect the required data for a very short time and to fall asleep fore some more seconds afterwards. During these long times of hibernation nearly no compunting power and therefor nearly no additional battery capacity is used.
As an additional bonus this App offers the possibility to auto-connect to open Freifunk-WLAN networks that are available to the public. As soon as this happened all data are transferred via this network, so this function acts as some kind of automatic internet connection which does not cost you any fees for the data transfer. This option can be enabled within the preferences.
ATTENTION: this function should be enabled only in case your device is secured so that no private data are sent unencrypted! There is the possibility somebody created such an open WLAN as some kind of trap to attack your device or to grab your personal data. But if you protect your device, this function is a nice possibility to have automatic access to public networks and to the internet.
