Not always the case. One of my students worked on her thesis where she set up a bunch of XO-1 laptops over a 802.11s (draft) mesh and tested simultaneous calls to look for saturation, etc. https://www.dropbox.com/sh/0gszp4447j1g2qn/AAAxdUv_tNbstjzmD6BI1-jla/tilila-moujahid-thesis.pdf?dl=0 I'll see if I can find the actual thesis.
