Abstract: An electronic device is provided. The electronic device includes a plurality of antennas to communicate with an external electronic device and at least one processor operatively connected to the plurality of antennas. The processor is configured to detect a tracking start event using an external magnetic material positioned at a location adjacent to the electronic device, to track a location of the external electronic device using the plurality of antennas and, while the tracking is performed, to obtain a height value of the external electronic device when an angle between the electronic device and the external electronic device is a specified angle. The processor is further configured to change a specified condition based on the obtained height value, to detect a tracking end event based on the specified condition, and to change an operating mode associated with the electronic device in response to detecting the tracking end event.

Abstract: Disclosed herein is a multi-band ZigBee transceiver for supporting IEEE 802.15.4 wireless communications. In the multi-band ZigBee transceiver, a Multi-Mode Modem (MMM) selects any one of a European version standard using 860 MHz band, a US version standard using 920 MHz band, and a worldwide version standard using 2.4 GHz ISM band among IEEE 802.15.4 standards. A frequency synthesizing unit variably adjusts a carrier frequency according to the transmission standard. A transmission unit receives a digital modulated signal, low-pass-filters the digital modulated signal with a bandwidth thereof being variably adjusted, and up-converts the filtered digital modulated signal into an RF modulated signal corresponding to the selected transmission channel.
