The North Miami Beach Police Department is building a Wi-Fi network using Tropos gear: The police had used a CDPD network to access data but the operator is shutting down its CDPD network. The department expects to save a bundle by not having to pay an operator a monthly fee for using the network.
The Wi-Fi network currently only covers a few square blocks but plans call for it to stretch five square miles. That's not a very big area so I wonder what the cops will do outside of that area.
