    9 These measurements demonstrate an RSSI of around -65 dBm at a 300 m straight-line distance, even in the presence of multiple buildings blocking line of sight. As would be expected, the locations close to the node experience a high RSSI an hence high SNR.
     9These measurements demonstrate an RSSI of around -65 dBm at a 200m  distance down the street. As would be expected, the locations close to the node experience the highest RSSI.

    11 Of particular note are the measurements in the southeastern area. This area is not only shadowed by several buildings, but is also outside of the beam width of {{{s3-lg1}}}'s antenna. This demonstrates that {{{s3-lg1}}} provides coverage for a significant area of the Columbia campus, making it useful for experiments undertaken in this area.
     11Up to -75 dBm coverage is achieved up to 70m up a street which is around a corner.
