使用 IEEE 802.15.4 技术在室外环境中报告传输损耗测量结果，用于监测和跟踪小型反刍动物。显示了最简单的可能的传播模型，以反映测量的传播数据的一般特征。然而，其绝对精度可能不足以用于基于模型反演而不优化其参数的定位算法。建议进行模型校准以反映传播环境的站点间变化，作为实现具有有用精度和足够可移植性的定位系统的可能方法。
Transmission loss measurements using IEEE 802.15.4 technology are reported in an outdoor environment for application to monitoring and tracking of small ruminants. The simplest possible propagation model is shown to reflect the general features of the measured propagation data. Its absolute accuracy, however, is probably inadequate for use in a location algorithm based on model inversion without optimization of its parameters. Model calibration to reflect inter-site variation of the propagation environment is suggested as a possible way of realizing a location system with useful accuracy and adequate portability.
