COSMOS is split into several domains, which are reserved separately.

They represent physically distinct sets of hardware, with specific purposes and usage goals.

The recommended usage pattern is to use the sandboxes to develop and debug experiments, before running them on the main "bed" domain to collect real results. In addition, most sandboxes are less affected by "real world" variance in performance from outside factors.

Indoor Sandboxes

    • This is the first development sandbox located at WINLAB in North Brunswick, NJ.
    • It consists of:
      • Two roof mounted radio sectors
      • Two indoor USRP 2974, with Sivers based MMWave frontend for development.
      • Several stationary "mobile" nodes, for development.
      • Two servers shared by all radios.

    • This is the second development sandbox, located at Columbia University in New York City, NY.
    • It consists of:
      • Two "sectors" worth of radios, but all colocated in one rack indoors.
      • 4 Full duplex frontends
      • 2 MMwave frontends
      • Support hardware to connect frontends to desired radios
      • Two servers shared by all radios

This is the main testbed in New York City, NY.

It currently consists of:

  • Radio Sectors around the Mudd Building at Columbia
    • 1 at 1st floor
    • 1 at 2nd floor
    • 3 at 18th floor
  • Servers for processing the radio data
    • 4 dedicated to the 18th floor radios
    • 2 that are shared by all sectors

All devices are connected by the optical network described at Hardware/optical

Each radio sector contains a USRP N210 and a USRP 2974, fiber connectivity, RF frontends, and antennas, as well as various support hardware to ensure its reliable operation.
