{\TeX\ in industry \acro{II}\Dash designing converged network solutions} {Stefan Kottwitz} {Pure graphics, with efficient use of \TeX\ and \TikZ\ for programming drawings of network architectures (\acro{LAN}, wi-fi, \acro{V}o\acro{IP}, \dots). Efficient in the sense of my note at \url{http://tex.stackexchange.com/a/297029/213}. Quick sample notes: \url{http://tex.tips/tag/industry}. Example drawings: \url{http://tex.tips/LAN-1-2.pdf}. Presenting a showcase what can be done with \TeX\ (instead of Visio, PowerPoint or \acro{CAD}) and how, with a view toward efficiency (time pressure on projects). }
