Wireless tracking systems could be used to protect patients in hospitals and students on campuses, backers of the technology said.
The combination of Radio Frequency Identification (RFID) tags and wi-fi allows real-time tracking of objects or people inside a wireless network.

Angelo Lamme, from Motorola, said tracking students on a campus could help during a fire or an emergency.

"You would know where your people are at any given moment," he said.

Marcus Birkl, head of wireless at Siemens, said location tracking of assets or people was one of the biggest incentives for companies, hospitals and education institutions to roll out wi-fi networks.

Tis a good idea in principle, but will be heavily abused imho.
