Node {{{md2}}} is a [https://wiki.cosmos-lab.org/wiki/Hardware/Nodes#MediumNode Medium Node] located on the second floor of the Mudd Building at Columbia University, overlooking Amsterdam Avenue. The [https://wiki.cosmos-lab.org/wiki/Hardware/antennas#Omni-directionalmediumnode omni-directional antenna] has line-of-sight to the majority of Amsterdam Ave. between 116th St. and 122nd St., as well as to parts of 120th St. and 119th St. headed east.

==== Coverage
[https://wiki.cosmos-lab.org/wiki/Hardware/Nodes/Measurements Coverage measurements] are currently being performed in the area around {{{md2}}}. In total, around 100 measurements have been taken on sidewalks in the area spaced by roughly 5m-spaced. The measurement results are presented below.

 || Figure 1: Coverage measurement results for {{{md2}}}.

These measurements demonstrate an RSSI of around -72 dBm at a 200m  distance down the street. As would be expected, the locations close to the node experience the highest RSSI. 

Up to -82 dBm coverage is achieved up to 70m up a street which is around a corner.

==== To-Do
Measurements to the north of Amsterdam Ave (the street in the centre of Figure 1)

Measurements on 120th St. (the street in the northeast of Figure 1)

Measurements on 118th St. (the street in the southeast of Figure 1)
