A concept for wildlife tracking using ultra high frequency (UHF) radio
Wildlife tracking technology is a method routinely used in the detection of small animals or big animals. Normally, a radio tracking using a low frequency between 30MHz to 300MHz known as Very High Frequency (VHF). In this study, a band of Ultra High Frequency (UHF) with a frequency 315MHz is use...

| Summary: | Wildlife tracking technology is a method routinely used in the detection of
small animals or big animals. Normally, a radio tracking using a low frequency
between 30MHz to 300MHz known as Very High Frequency (VHF). In this study, a
band of Ultra High Frequency (UHF) with a frequency 315MHz is used as a
transmitter. While a encoder HT12E is used as a function of generate a data signal to
the RF Transmitter module 315MHz to transmit. The signal sent by the transmitter
detected by Yagi antenna as a receiver and was designed at a frequency of 315MHz
with a gain is 10.68dBi. Received power detected by Yagi antenna shown at Anritsu
Spectrum Analyzer. The highest differences between power received at vegetation
area compared to open area is about 10dBm while the furthest distance of the
receiver can be traced in the vegetation area is about 67 meters, and for open area is
more than 70 meters. The results of this study agreed with Tamir’model for
propagation in forest whereas can be used in a prediction of initial pattern of power
received signal which is gradually decrease if a receiver moves away from the
transmitter over much larger distances. |
