and construction does not actually result from the inspection; the intended purpose of the operation of the
UWB device is to determine if construction is required.  We also believe that the GPRs and wall imaging
systems may be operated for one of the purposes described in the regulations but need not be operated
directly by one of the described parties.  For example, a GPR may be operated by a private company
investigating forensic evidence for a local police department.  
FCC Permitted Mode of Usage
The GPR antenna must be kept on the surface to be in compliance with FCC regulations.  Use of the
antenna is not permitted if it is lifted off the surface.  Use as a through-the-wall imaging device is prohib-
ited.  
GPR Use Coordination
FCC regulation 15.525(c) (updated in February 2007) requires users of GPR equipment to coordinate the
use of their GPR equipment as described below: 
TITLE 47--TELECOMMUNICATION 
CHAPTER I--FEDERAL COMMUNICATIONS COMMISSION
PART 15_RADIO FREQUENCY DEVICES
Subpart F_Ultra-Wideband Operation Sec.
15.525  Coordination requirements.
    (a) UWB imaging systems require coordination through the FCC before the equipment may be used.
The operator shall comply with any constraints on equipment usage resulting from this coordination.
    (b) The users of UWB imaging devices shall supply operational areas to the FCC Office of Engineering
and Technology, which shall coordinate this information with the Federal Government through the National
Telecommunications and Information Administration. The information provided by the UWB operator shall
include the name, address and other pertinent contact information of the user, the desired geographical
area(s) of operation, and the FCC ID number and other nomenclature of the UWB device. If the imaging
device is intended to be used for mobile applications, the geographical area(s) of operation may be the
state(s) or county(ies) in which the equipment will be operated. The operator of an imaging system used
for fixed operation shall supply a specific geographical location or the address at which the equipment will
be operated. This material shall be submitted to:

    (c) The manufacturers, or their authorized sales agents, must inform purchasers and users of their sys-
tems of the requirement to undertake detailed coordination of operational areas with the FCC prior to the
equipment being operated.
    (d) Users of authorized, coordinated UWB systems may transfer them to other qualified users and to dif-
