What is the SubPos Wi-Fi Positoning Standard?

The SubPos Wi-Fi Positoning Standard is a dataless positioning system that doesn't require expensive licencing, specialised hardware, laborious area profiling or reliance on data connectivity (a connection to a location database or cellphone coverage is not required), all while remaining backwards compatible with existing Wi-Fi access points and receivers. It works independently of, or alongside GPS/Wi-Fi Positioning Systems (WPS)/Indoor Positioning Systems (IPS) as an additional positioning data source by exploiting hardware commonly available.
