0 INTRODUCTION
0.1 General
This description is focused on the IEEE 802.15.4TM Keyfob remote control from
FALCOM GmbH. It contains short information about purpose and use of the Keyfob
concept.
The Keyfob remote control contains an IEEE 802.15.4
GHz ISM-Band. It uses 16-channels in interval of 5 MHz (2405–2480 MHz).
The Keyfob supports an over-the-air data rate of 250 kb/s by using the O-QPSK (offset
quadrature phase-shift keying) modulation type. The duty-cycle with the PHD100
device is:
- 1 ms transmit (Tx)
- 300 ms receive (Rx)
- 5 s sleep
Based on these features, the Keyfob will spend most of its operational life in a sleep
state that favor the AAA-batteries a long lifetime; however, the Keyfob periodically
listens to the RF channel in order to determine whether a message is pending.
The Keyfob has an internal Multi-Layer-Ceramics antenna from Murata with the gain
TM
of –1 dB. The IEEE 802.15.4
module works with a chipset from Freescale called
MC13192 (Transceiver), MC9S08GT60 (8-bit Processor).
The keyfob operates with the help of three buttons. It supports 3 LEDs, a buzzer and
a vibrator for signal indication.

2 BI-DIRECTIONAL KEYFOB, REMOTE OPERATION
The Keyfob gives you remote operation of your security system. This Keyfob operates
with the push of one button or buttons combination. It also gives you direct
feedback on its operation with a blinking light as well as with voice prompts, so you
can be sure that your security system is operating as you intended. The
communication to the Keyfob unit is based on the IEEE 802.15.4 wireless network
systems.
