    22== Types / Domains
     3COSMOS is split into several domains, which are reserved separately.
     4
     5They represent physically distinct sets of hardware, with specific purposes and usage goals.
     6
     7The 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.
    38=== Sandboxes
     9==== sb1.cosmos-lab.org
     10This is the first development sandbox located at WINLAB in North Brunswick, NJ.
     11
     12It consists of:
     13* Two roof mounted radio sectors
     14* Two indoor USRP 2974, with Sivers based MMWave frontend for development.
     15* Several stationary "mobile" nodes, for development.
     16* Two servers shared by all radios.
     17
     18 [wiki:/hardware/Domains/sb1 more info]
     19
     20==== sb2.cosmos-lab.org
     21This is the second development sandbox, located at Columbia University in New York City, NY.
     22
     23It consists of:
     24* Two "sectors" worth of radios, but all colocated in one rack indoors.
     25* 4 Full duplex frontends
     26* 2 MMwave frontends
     27* Support hardware to connect frontends to desired radios
     28* Two servers shared by all radios
     29
     30 [wiki:/hardware/Domains/sb2 more info]
    431=== Indoor
    532=== Outdoor
     33==== bed.cosmos-lab.org
     34This is the main testbed in New York City, NY.
     35
     36It currently consists of:
     37* Radio Sectors around the Mudd Building at Columbia
     38  * 1 at 1st floor
     39  * 1 at 2nd floor
     40  * 3 at 18th floor
     41* Servers for processing the radio data
     42  * 4 dedicated to the 18th floor radios
     43  * 2 that are shared by all sectors
     44All devices are connected by the optical network described at [wiki:/hardware/optical#Optical]
     45
     46Each 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.
