- Fundamentals of Radio Tomographic Imaging - Part 1Nodes vs Links Consider a wireless network consisting of \(K\) number of devices. If each and every device is communicating with each other, there will be a wireless link between each and every pair of nodes. The number of such unique two-way links is depicted as \(M\). The following equation describes relationship between \(M\) and […]
