We have already seen a number of ideas for tracking tags seeking funds on Kickstarter, most systems are limited by the range of Bluetooth communication with a smart device. This system from Iotera tackles the problem using cloud-based thinking: Β The basic wireless system consists of one or more tags or βiotasβ and a home base unit. Each 22 x 11 x 3Β mm iota contains a GPS chip, accelerometer, temperature sensor, speaker, RF transceiver,
Bluetooth (unused so far) and a battery to give up to three months operation. Each iota communicates with the home base unit using wireless channels in the 902 to 928Β MHz band giving a range of up to four-miles. Β Back home, the base unit receives the low-speed transmissions from the iota tag and forwards the information to a server via a Wi-Fi connection.
