Systems and methods for trajectory prediction to enable seamless access using mobile devices

A computer program product tangibly embodied on a computer readable medium, the computer program product including instructions that, when executed by a processor, cause the processor to perform operations comprising:

• detecting a first sequence of signal strengths between a mobile device and one or more access controls over a first time period;
• detecting an access request from the mobile device to a final destination access control of the one or more access controls on along a first route when the first time period has expired;
• associating the first sequence of signal strengths over the first time period with the first route to the final destination access control;
• detecting a second sequence of signal strengths between the mobile device and one or more access controls over a second time period;
• and
• determining that the second sequence of signal strength correlates with the first sequence of signal strengths and that the mobile device is on the first route to the final destination access control during the second time period.
