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.

In total, around 100 measurements have been taken on sidewalks in the area spaced by roughly 5m-spaced. The measurement results are presented below. || [[Image(rssi_coverage_map_md2.png, 800px)]] || 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.
