Abstract

The necessity of monitoring of the wilds birds across the border by using ICT is already confirmed in International Telecommunication Union (ITU). We developed a ultra-compact bird-borne S-band transceiver, which the biological information and the positional information of the birds can be obtained by using the bird -to-bird communications and the bird -to-centre communications. This transceiver is composed of Texas Instrument Inc.CC2500 packet communication device and can choose a transmission speed from 1200bps to 500kbps, and can choose a modulation from 2FSK, GFSK, MSK, OOK. We sought the optimal parameter for both communications by using the evaluation experiment.

1 Objective

The bird-borne S-band transceiver is composed of Texas Instrument Inc. CC2500 for packet communication. This device can choose a modulation-technique from 2FSK, GFSK, MSK, OOK. The objective of this paper is to seek the optimal parameter of the bird-to-bird communications and the bird-to-centre communications by using the evaluation experiment.

2 Background

The necessity of monitoring of the wild birds across the border by using ICT is already confirmed in International Telecommunicatio n Union (ITU) [1]. In the past, the wilds birds were tracked by the ARGOS system, which used NOAA satellite. However, the measured position accuracy wasn't so high and there was a limit in the memory capacity for the measured data [2]. Therefore, by attaching the transceiver to the wild birds, we have started the research to get the biological information and the positional information by using the bird-to bird communications and the bird-to-centre communications [2].

. For bird-to-bird

communication, the autonomous decentralized

RBBS first exchanged data between files, then

collected files possessed by one bird, but not others.

First installed in the PAX

-88B packet radio

communication modem by Escuela I

nc.

(Yokohama) in 1988, this RBBS function has been

used successfully in the area of radio

communications.

Because the CPU mounted on the transceiver
