I happened to hear part of a radio interview with Professor Warwick
The basis appears to be LCS over the GSM network (he made a comment
that one of the issues was that they had to get the network operators
to "buy in" to doing this experiment). The positional resolution for
planned to be about 10metres, when it is implemented, not 1 metre.
As I recall, the battery recharge was not a major obstacle, they just
to decide which way to do it. A larger issue was the system design to
as long as possible between charges (1 week was mentioned).
The girl has not been chipped yet, as the article you quote said: "in
Implantation is to be "in a fleshy part of the body", I'll leave it up
others where would be suitable in a teenage girl, that a kidnapper
