13. The device of claim 1 wherein the data transmitted includes:

(a) at least one of a battery charge level, a temperature, a barometric pressure, a code relating to an accessory for the medical device, a data validity measurement, an elapsed time since a previous reading by the medical device, a test result parameter, a signal-to-noise parameter, and a quality of service (QoS) parameter;

(b) a user's: heart rate, blood oxygen level, perspiration, electrical resistance on the skin, movement, blood pressure, fall or sudden impact, calories used, calories consumed, or body temperature; and

(c) ambient air temperature, time, day, and location.

14. The device of claim 1 wherein the data transmitted by the device is encrypted.

15. The device of claim 14 wherein data is encrypted utilizing a private encryption key associated with the user.

16. The device of claim 1 that is configured to contact an emergency center and provide a user's location if the device senses an emergency.

17. The device of claim 16 wherein the emergency is one or more of (a) a sudden impact, (b) undesirable physical location, and (c) transmission by a user of an emergency.

18. The device of claim 1 that is configured to communicate with an intermediary device that performs a diagnostic test on the device to determine if the device is functioning properly.

19. The device of claim 1 that is configured to perform a diagnostic test on itself to determine whether it is functioning properly.

20. The device of claim 19 that is configured to generate an alert in response to a determination that it is not functioning properly.

21. The device of claim 1 wherein one or more of the device, an intermediary device, a coordinator, and a gateway is configured to receive and install a software update directly, or indirectly, on the device.
