I have a clinic that is wanting to provide Guest WiFi to their parking lot for patients that do not have internet at home. The clinic wants to be able to do tele-medicine over this link. They anticipate a low amount of people that would use this, perhaps 3 or 4 people at a time. The closest parking spot from the suggested AP location is about 30 ft. The furthest is 110 ft. I am going to recommend putting signs at the nearest four parking spots that range from 30 ft away to 62 ft away indicating these are intended for tele-medicine. I am looking at an MR74 with dual-band omni antennas. Does this sound viable? What other recommendations or warnings do you all have?
