Abstract: A wireless communication device includes a first transceiver operable according to a first radio technology and a second transceiver operable according to a second radio technology and operable concurrently with the first transceiver. The wireless communication device further includes an antenna configured to transmit radio transmissions of the second transceiver, and a filter circuit coupling the second transceiver with the antenna. The filter circuit includes a first frequency path and a second frequency path in parallel. The first frequency path passes a first set of frequencies of the radio transmissions and the second frequency path passes a second set of frequencies of the radio transmissions. One of the first frequency path or the second frequency path is configured to filter the radio transmissions of the second transceiver to remove signals corresponding to the one or more operating frequencies of the first transceiver from the radio transmissions of the second transceiver.

Abstract: A security system comprises a control panel configured to control devices in a security system, a keypad and an arm/disarm device. The keypad is in communication with the control panel and comprises a transceiver configured to communicate with the control panel and a magnet having a magnetic field extending within a predetermined proximity of the keypad. The arm/disarm device comprises a transmitter and a switch configured to activate the transmitter when the switch is in the magnetic field. The transmitter is further configured to transmit a low power signal when activated. The transceiver is further configured to receive the low power signal and transmit a message to the control panel. The control panel is further configured to change an Armed/Disarmed Mode of the system based on the message.
