Node Specifications

There is currently only a single type of node available in the City of Things testbed. It consists of of an apu2c4 embedded pc with two WiFi interfaces and a number of additional radio modules that are connected through USB. It supports the following wireless technologies out of the box:

• WiFi 802.11ac on 2.4 GHz and 5GHz
• IEEE 802.15.4 on 2.4 GHz and 868MHz
• Dash7 on 433MHz and 868MHz
• LoRaWAN on 868MHz (client only)

All these components are housed in a waterproof metal box to protect them from the elements. The antenna's of the node are housed in a separate (plastic) enclosure and the two are connected by low-loss coax cables.
