1. A system for monitoring activity of a subject and occurrence of a fall of the subject, said system comprising:
- a sensing unit configured for placement at the base of the back of the neck of the subject, said sensing unit being configured for a low G/high G acceleration sensing range; and
a base configured to wirelessly communicate with said sensing unit;
said sensing unit being configured to wirelessly transmit acceleration data measured by said sensing unit in the low G and in the high G acceleration range and correlated to the spine of the subject due to said placement at the base of the back of the neck of the subject;
wherein said base is configured to receive said acceleration data measured by said sensing unit in the low G and in the high G acceleration range and sent by said sensing unit;
said base being further configured to process the acceleration data in the low G and in the high G acceleration range into data reflecting a vectorial position of the spine of the subject due to said placement at the base of the back of the neck of the subject;
said base being further configured to identify a fall of the subject based at least on said acceleration data measured by said sensing unit in the high G range and to determine levels of activity of the subject based at least on said acceleration data measured by said sensing unit in the low G range.
