Scientific infrastructure

In order to support cutting-edge research, IMDEA Networks invests in the latest, state-of-the-art laboratories and laboratory test equipment, endowing the Institute with the capacity of transforming research into high added value products and services.

These laboratories are used for:

  • Constructing prototypes and measuring the devices, protocols and algorithms developed by the researchers.
  • Simulating complex base-band and medium access systems, as well as sophisticated radio subsystems.
  • Measuring radio parameters involved in mobile, fixed and satellite communications, designing and characterizing radiating elements, and measuring the effects on the radio electric spectrum of new protocols and algorithms designed by the Institute.

Examples of the laboratories capabilities include:

Ubiquitous Wireless Networks Lab

Underwater communications testbed

 

This is a collection of 4 underwater acoustic transceivers that operate in the 18-36 kHz band. They are connected to semi-rugged laptop computers through a switch and waterproof underwater cables. They can be operated both from a bench power supply (like in this picture) and from batteries.

 

 

 

 

 

Neptune, the horse power server of the underwater laboratory: This is a DELL PowerEdge server that is employed to run computer simulation for underwater communications, localization, and networking. It is also used as a remote control center for the UWN group's underwater acoustic transceivers.

MONROE Testbed at IMDEA Networks: Consists of 20 static nodes. 4 are development nodes and 12 testing nodes. These nodes are also connected through Ethernet alongside WIFI and LTE connectivity.

 

Dynamic Provisioning testbed

 

An isolated LAN consisting of 4 laptops (all running Ubuntu Linux 16.04 LTS) connected via a GB Ethernet switch. All PCs also have an external wireless connection to facilitate monitoring of the experiments via the IMDEA network. The laptop in the middle acts as the Data Centre which hosts Virtual Machines that provide a Video On Demand service. The other laptops send out requests for particular video segments in a given format to the host. The host laptop on receiving this request directs it to a VM or VMs specifying the client address and port to stream back a transcoded version of the segment.

mmWave band radio link

The Sivers IMA form the building block for mmWave band radio link applications. Each unit consists of one up- and one down-converter. The up- and down-converters operate independently. The boards are used as a reference design for e.g. an RF front end for a point-to-point or point-to-multipoint radio link. The evaluation board offers all necessity for interfacing the converter modules with the I/Q baseband inputs and outputs of a modem. RF output/input is over WR15 waveguide. The antennas provided by the lab are omnidirectional and directional with apertures of 7, 20, and 80 degrees.
