Core technologies
Groundhog Technologies launched its Mobility Intelligence platform based on chaos theory and multi-dimensional modeling. The application of chaos theory gave rise to the company's mathematical models of subscribers' mobility and usage behavior,{{cite web|title=Management system and method for wireless communication network and associated user interface|url=http://patents.justia.com/patent/7747254|website=Justia Patents|accessdate=30 June 2014}} which can be used for different applications such as by mobile operators to optimize networks according to the user demands.{{cite web|title=System with user interface for network planning and mobility management optimization in a mobile communication network and method thereof|url=http://patents.justia.com/patent/7561876|website=Justia Patents|accessdate=30 June 2014}}

According to chaos theory, some seemly random or chaotic signals may be converted to analyze in phase space which can reveal the patterns behind it. The cases of most interest arise when the chaotic behavior shows patterns around an attractor in the phase space. Based on the attractor in the phase space, data can be used from different space, time, and individuals for modeling and indoor geolocation.
It is also found that the dimensional structure and characteristics of phase space can naturally neutralize the bias of positioning (based on techniques such as triangulation or trilateration) caused by reasons such as multipath. That is, although each input is biased in some way, the observation from different dimensions and angles are biased in different ways. Combining multi-dimensional input in the phase space, based on the law of large numbers it can average out the bias with different samples through dimensions, time, and individuals.{{cite web|title=System for constructing a mobility model for use in mobility management in a wireless communication system and method thereof|url=http://patents.justia.com/patent/8031676|website=Justia Patents|accessdate=30 June 2014}}
