Despite those findings, the publication reported that the FCC has only issued two citations to mobile operators since rules were adopted in 1996. Under a consent decree signed with the FCC this past spring, Verizon Communications (NYSE: VZ) agreed to pay $50,000, train employees and contractors, and check other sites after it was accused of RF violations in Pennsylvania and Connecticut related to unlocked access to a rooftop and a missing sign. Further, in one recent instance, engineer Marvil Wessel spotted lawn chairs near a T-Mobile US (NYSE:TMUS) antenna installation whose emissions violated safety limits. The structure was painted brown to match a fence. Upon notification from the Wall Street Journal, T-Mobile installed warning signs and a chain to restrict access in front of the antenna. However, property owners and residents often become upset regarding RF notification signs, which they oppose due to aesthetics and concerns they might reduce their property value.
