1. A method for proximity based secure communications, comprising:
- defining a proximity boundary with dimensions defined by a selected communication range of one of a first Short Range Communication (SRC) device and a second SRC device, wherein each of the first and second SRC devices are configured to communicate using near field magnetic induction (NFMI), and the first SRC device is configured to be coupled to a first computing device and the second SRC device is configured to be coupled to a second computing device;
communicating an NFMI proximity signal in the proximity boundary between the first SRC device and the second SRC device, wherein at least one of the first and second SRC devices includes at least two antennas to provide magnetic induction diversity, and using the magnetic induction diversity to substantially reduce a variability of the dimensions of the proximity boundary;
selecting secure data for NFMI communication on a spatially secure NFMI data link between the first and second computing devices when the proximity signal is detected between the first and second SRC devices; and
selecting non-secure data for communication on a radio frequency (RF) data link from at least one of the first and second computing devices using one of a wireless local area network (WLAN) radio and a wireless wide area network (WWAN) radio when the proximity signal is detected between the first and second SRC devices.

Abstract
Spatially enabled secure communication technologies are disclosed. A proximity boundary can be defined by a communication range of one or more SRC devices configured to communicate using near field magnetic induction (NFMI) using at least two antennas to provide magnetic induction diversity. Secure data can be selected for NFMI communication on a spatially secure NFMI data link between the one or more SRC devices. Non-secure data can be selected for communication on one of a wireless local area network or a wireless wide area network.
