One obvious choice for pushing messages to the field would be multicast ( on any band, depending on the range you are after, etc.. )
One transmitter pushes the data to an unlimited number of recipients, who all get it at the same time. No point-to-point system can compete with it, multicast is much, much faster for distributing the same data to many locations.
