**NOTICE OF UNLICENSED OPERATION**

Case Number: EB-08-LA-0295 Document Number: W200932900001

The Los Angeles Office received a complaint from Verizon Wireless
("Verizon"), a FCC licensed user, that radio emissions from your
building were causing interference to their cellular sites. On October
7, 2008, an agent from this office confirmed by direction finding
techniques that radio signals, including those on frequency 842 MHz,
were emanating from a building occupied by Wood Group Field Services,
Inc. ("WG") in Santa Fe Springs, CA. An Operations Manager informed the
agent that an amplifier had been installed to increase the signals for
mobile phones. In a subsequent telephone conversation, another employee
informed the agent that a BDA (bi-directional amplifier), which is an
in-building radiation system[^1] had been removed from service as a
result of the complaint.

Section 22.383 of the Commission's Rules[^2], which applies to Public
Mobile Services licensees, provides that "\[l\]icensees may install and
operate in-building radiation systems without applying for authorization
or notifying the FCC, provided that the locations of the in-building
radiation systems are within the protected service area of the
licensee's authorized transmitter(s) on the same channel or channel
block." A licensee's authority to install a BDA does not, without
further authorization from the licensee, permit a subscriber to install
a BDA.

The frequency 842 MHz is authorized for use by Verizon. Verizon has
informed the Commission that it did not provide you authorization to
install a BDA. Furthermore, Commission records show no license issued to
WG for operation of a radio station at this location on 842 MHz.

Operation of radio transmitting equipment without a valid FCC
authorization or license is a violation of Section 301 of the
Communications Act of 1934, as amended.[^3] You are hereby warned that
operation of radio transmitting equipment without a valid radio station
authorization constitutes a violation of the Federal laws cited above
and could subject the owner of this illegal operation to severe
penalties, including, but not limited to, substantial civil forfeitures,
a maximum criminal fine of \$100,000 and/or one year imprisonment, or
arrest of the equipment for the first offense (*see* 47 U.S.C. §§ 501,
503 and 510).

**UNLICENSED OPERATION OF THIS RADIO STATION MUST BE DISCONTINUED
IMMEDIATELY**.

You have ten (10) days from the date of this notice to respond with any
evidence that you have authority to operate granted by the FCC. Your
response should be sent to the address in the letterhead and reference
the listed case and document number. Under the Privacy Act of 1974, 5
U.S.C. § 552a(e)(3), we are informing you that the Commission's staff
will use all relevant material information before it to determine what,
if any, enforcement action is required to ensure your compliance with
FCC Rules. This will include any information that you disclose in your
reply.

You may contact this office if you have any questions.
