分子通信（MC）是一种使用化学物质或分子而不是电磁波来传输信息的方法。迄今为止，MC的研究主要集中在纳米（nm）到微米（$\mu \text{m}$）尺度上，只有少数的宏观尺度上的实验研究。本文对宏尺度MC的特性进行了实验研究。它们是信号流（$q$）、载波流（$Q$）和比特持续时间（$T$）。使用带有四极杆质量分析器的质谱仪作为检测器，使用内部建造的气味发生器作为化学脉冲发生器。本文证明了信号能量与信号流量成二次函数关系，而载波流量与信号幅度和信号能量成非线性关系。比特持续时间表明，随着比特持续时间的增加，系统达到饱和点，并且这种效应也发生在比特传输后的剩余化学信号中。最后，首次建立了一个数学模型，用对流扩散方程解释了宏观尺度上的分子传输。
Molecular communication (MC) is a method where the transmission of information involves the use of chemicals or molecules instead of electromagnetic waves. The study of MC to date has mostly focused on the nano (nm) to micro ( $\mu \text{m}$ ) scale and there have been only a few experimental studies on the subject of macro-scale. In this paper properties of macro-scale MC are experimented and studied. These are signal flow ( $q$ ), carrier flow ( $Q$ ), and bit duration ( $T$ ). A mass spectrometer with a quadrupole mass analyzer is used as the detector and an in-house-built odor generator is used as the chemical pulse generator. This paper has shown that the signal energy has a quadratic relation to signal flow whereas the carrier flow has a non-linear relation to both the signal amplitude and the signal energy. The bit duration has shown that the system reaches a saturation point as the bit duration is increased and this effect also occurs in the leftover chemical signal after bit transmission. Finally, a mathematical model is developed for the first time to explain the molecular transmission on the macro-scale using advection-diffusion equation.
