The radio technology being used is likely to be [Zigbee](http://www.zigbee.org) (because it is more tolerant of errors; albeit with lower bandwidth than wifi or cellular). The "slaves" (need a better word) are also zigbee enabled and can communicate with the anchor points to transfer data (such as location, attached peripherals, internal data). The anchor points can be BeagleBone devices, which can use an Internet connection to communicate with and "optional" central server. That Internet connection can be (for example) Wifi, LAN, 4G, ...
