Hardware

The hardware used Dresden Elektronik radio communication platform described on this page consists of three types of components:

  • Radio/microcontroller modules
  • Development boards (can also be replaced with a custom board)
  • Sniffer (for analyzing communication between the nodes)

Radio/microcontroller modules

The Dresden Elektronik radio/MCU modules are small modules consisting of a AVR or ARM based microcontroller with integrated radio. List of all available modules can be seen here.

As of July 2015, three types of Dresden Elektronik Radio/microcontroller modules were available in the institute:

  • deRFmega128
  • deRFmega256
  • deRFarm

Power consumption (Sleep) < 1 µA < 1 µA < 250 µA

The 2.4 GHz transceiver that is used in all the modules supports the IEEE 802.15.4 MAC standard. The IEEE 802.15.4 MAC standard has support for additional network layers like 6LoWPAN and ZigBee (It should be noted, that although the ZigBee protocol is theoretically supported by the standard, it is not supported by the Dresden Elektronik communication stack).
