Yes, and yes.<p>A recent news report mentioned that a &quot;cell tower&quot; moved along with participants in a demonstration (in London IIRC), and also that it switched networks, so obviously someone noticed that.<p>Time division logic involves keeping track of how far each phone is from the tower. I think GSM uses 50m or 100m bands, ie. phones that are 200m from the tower time their broadcast bursts so as not to conflict with phones that are 100m from the tower. I don&#x27;t know whether the distance information is available to the phones, or is kept internally in the tower, though. (I&#x27;m not an expert on this, I just heard that this need paid for a fair amount of NTP research&#x2F;development, many years ago.)
