     19The measurements show -77 dBm RSSI at a link distance up to 550m distance away. The location with highest signal strength received was on 120th St in within the 3dB beam width of the antenna. These measurements demonstrate that s2-lg1 provides coverage to a significant portion of Broadway almost up to 125th St, along with streets between Broadway and Amsterdam Ave. Coverage also extends to Riverside Park and portions of Claremont Ave.
