In order to extend use of calcium carbonate, the samples were modified by hydrazine hydrate, triethanolamine and sodium stearate. Hydrazine hydrate was 0.08%～0.24% of calcium oxide, triethanolamine was 0.1%～0.3% of calcium oxide, sodium stearate was 5% of calcium carbonate,modification time was 40 minute. Calcium carbonate has better active exponent and white degree.

In this thesis, we proposed a robust trilateration method to estimate Path Loss Exponent which stands for the signal attenuate rate for each reference node to target path by using two different frequency signals and the trilateration method. Then we used every PLE to calculate the corresponding distance and performed the trilateration positioning task using these distances. We also ran two simulations to evaluate our proposed method.

但另一方面，即使在同一空间中，却因为存在著许多变数而导致各个不同的路径都拥有自己的路径衰减指数，所以此篇论文我们提出先利用两个不同频率的讯号测得参考点到目标上的路径衰减指数后，再利用此数值做此路径的距离推导，最后再藉由三点定位法做出目标的定位。
