TWIST Wireless

Wireless testbeds enable to effectively test the wireless protocols or applications in a real-life environment. At our group we already have a scalable and flexible testbed architecture for experimenting with wireless sensor network applications in an indoor setting. We are now extending the functionalities of this testbed with new technologies and applications. Among other have distributed state of the art WiFi routers that would allow us to experiment with mesh or corporate/AP based WiFi networks. It will also allow us to look deeper into the topic of coexistence of different wireless technologies.

The following devices are supported:

  • Intel NUC Embedded PCs
  • TP-Link WDR4300 routers distributed in the whole TKN building

Users are given root access to the devices and can thus install any software required for experiments at will.


For better management of wireless spectrum at the University, we require all Wi-Fi AP names (BSSIDs) to start with tkn_. Violations to this rule might result in terminated node reservations and banned use of the testbed.
