iControl Incorporated http://www.iControl‐Inc.com miKEY Operations Background The miKEY “key fob” is a small, battery powered 802.15.4 compliant radio transmitter. A miKEY has one LED and three buttons and resembles the keyless entry device found with most modern cars. The intent of the miKEY is to allow control of a mLOCK at times when no other communication link is possible. For example, a truck driver may carry a miKEY along with cargo which is secured by an mLOCK so that, in the case of an unscheduled inspection, he could unlock and then re‐lock the cargo. Operation There are three buttons on the key fob: Power – blue button located top left. This button is pressed and held to power the radio transmitter and to begin transmission of a 1‐second burst of radio traffic. The LED will illuminate (and possibly blink) for the duration of the button press. Note: the other two buttons (grey) are intended for future use and currently do nothing. These buttons do not power the device, and therefore would have to be held in combination with the Power button. LED Power iControl Incorporated http://www.iControl‐Inc.com Each miKEY is typically paired with one mLOCK. The two devices share common configuration which may include: channel designations, encryption keys, and addressing information. It is also possible to configure a one‐to‐many scenario whereby one miKEY could communicate with many mLOCKs. Maintenance The miKEY uses a small replaceable battery. Battery replacement is currently only done by the manufacturer. Radio Transmission When the Power button is pressed, the 802.15.4 radio will transmit a burst of approximately 100 frames with a short (several milliseconds) gap between frames. The duration of the “burst” will be approximately 1 second or until the miKEY receives an acknowledgment from the targeted mLOCK. The intent of the burst is to signal a mLOCK which may be in a low power state. When the mLOCK receives one of the frames in the burst it will acknowledge the signal and the burst will terminate. When this occurs, the LED on the miKEY will blink once. All communication between the miKEY and the mLOCK is done using 802.15.4 data frames which are typically encrypted. 802.15.4 Channels The IEEE 802.15.4 specific ion defines a set of channels: 11 (2405 MHz) though 26 (2480 MHz). A miKEY will typically be configured to utilize two of these channels known as the “wake” and “sleep” channels. The signal burst consists of one frame on the “wake” channel followed by repeated frames on the “sleep” channel. If an mLOCK is not in low power mode (i.e. “awake”) it will respond immediately, otherwise it will respond to the first “sleep” frame it receives. iControl Incorporated http://www.iControl‐Inc.com FCC NOTICE: miKEY miKEY_V13 FCC ID: W2E‐MIKEYV13 !
