SubPos - A "Dataless" Wi-Fi Positioning System

SubPos is an extensible, open-source, Wi-Fi based indoor positioning system, that doesn’t require expensive licensing, specialised hardware, laborious area profiling or dependence on data connectivity (a connection to an online/offline location database is not required). With this, it also retains backwards compatibility with existing Wi-Fi access points and receivers.
The SubPos Standard defines an accurate method for subterraneous positioning in different environments by exploiting all the capabilities of Wi-Fi. Plug and play SubPos Nodes or existing Wi-Fi access points are used to transmit encoded positioning information in a standard Wi-Fi beacon frame, which is then used for passive, low-latency, location trilateration by a device of your choice (as long as it provides access to Wi-Fi scanning functionality).
Further developments are being made to increase the system’s accuracy using various techniques such as room zoning capabilities, dead reckoning and improved averaging functionality. A cost effective, extended ranging module is also in the works, to provide enhanced positioning accuracy and distance calculation between Nodes for hobbyist robotics applications.
A live demonstration with battery powered SubPos Nodes scattered about the presentation space will be shown. Audience members will be encouraged to try SubPos out on their own devices by downloading and running an Android demo application.

Does this system link to any global mapping such as GoogleMaps, Maps, or any mapping software. What is the accuracy in terms distance. Can you store relevant asset data such as owner, date of purchase, value etc.

[@papillonbit]

the page isn work , do you can update the link, please

[@abdulrahmanazizi6265]

what is the license cost estimate?

[@eoliu1140]

just wonder how to dodge from such location,like not feeding back rssi data, sometimes stalkers locate targets and they set up ppl by dropping sth illegal into their bags or pockets or talking about illegal stuff near targeted person as though she/he was partner, we r not escaping criminals,is there a way to not b located?

[@tylerthompson5797]

any news on the individual room and wall configuration? and has it gotten more accurate?

[@cali-co6428]

no one gonna say anything about this awesome thing?
