Examples could include finding the nearest printer or monitor or, perhaps trickier, could two roaming devices find each other? albeit lab digital chips is rarely cutting edge, I can see a day when all our sensors and probes will find data (wireless thermocouples are already available), and positioning cue will become much more important. What technologies exist to do this? How precise can the find be?"
