Hi, There is no rule of thumb for recommended distance between APs. There's the basic "1 AP per 25 client equipment’s" but I strongly suggest a site survey, focusing in which are the main areas you want/need coverage and what type of service would use the network (like just simple data or there would be voice services with roaming clients?). And also check which interference is generated by the workshop machines and other sources of RF interference (microwave ovens, motion/alarm sensors, neighbor rogue APs, etc). At the worst case scenario, if you don't have a RF spectrum analyzer or budget to pay for a Site Survey, you can install a MR33 and check the RF Spectrum status but if you want to pinpoint interference sources, you have to run a survey with a spectrum analyzer.
