                                 WARNING NOTICE

   On March 14, 2006, in response to complaints from Cingular Wireless
   ("Cingular"), agents from this office conducted an inspection of the
   in-building bi-directional amplifier (BDA) system that Sprint Nextel
   Corporation ("Sprint") installed and operated at the State Farm Insurance
   Facility, One State Farm Way, Concordville, PA. Cingular reported that the
   BDA system was significantly degrading the service it was able to provide
   its customers. The inspection confirmed that the BDA system operated by
   Sprint was causing harmful interference to Cingular's service.

   Sprint is licensed to operate in the 851-869 MHz Specialized Mobile Radio
   ("SMR) band under Part 90 of the Commission's rules ("Rules"). The BDA
   system employed by Sprint constitutes a Class B signal booster, as that
   term is defined in Section 90.7 of the Commission's rules ("Rules").
   Section 90.219 of the Rules provides that licensees authorized to operate
   radio systems in the frequency bands above 150 MHz are permitted to employ
   signal boosters, subject to the requirement that the booster retransmits
   only the licensee's authorized frequencies and that the licensees  are
   responsible for correcting any harmful interference such equipment may
   cause to other systems.   Any harmful interference must be resolved as set
   forth in Section 90.173(b) of the Rules,  which provides that licensees of
   stations suffering or causing harmful interference are expected to
   cooperate and resolve the interference problem through mutually
   satisfactory arrangements. If the licensees are unable to do so, the
   Commission may impose restrictions including specifying the transmitter
   power, antenna height, or area or hours of operation of the stations

   Although the interference at the State Farm Facility has been resolved,
   this office has continued to receive reports from Cingular of similar
   harmful interference to customers at various locations in the Philadelphia
   Metropolitan area, all of which contain a Sprint BDA system. Sprint has
   advised FCC agents that Sprint has developed an interference mitigation
   package, which includes replacement BDA equipment and external filters.
   Although this interference mitigation package has eliminated the harmful
   interference occurring at certain locations, Cingular customers continue
   to receive harmful interference at the following locations: (1) QVC
   Studio, 1220 Wilson Drive, West Chester, PA and (2) Cherry Hill High
   School East, 1750 Crescent Road, Cherry Hill, NJ. The interference
   mitigation package is not being implemented in a sufficiently timely
   manner at these locations.

   You are hereby warned that you have ten (10) days from the date of this
   Warning Notice to resolve the interference at the QVC Studio and Cherry
   Hill High School East. Failure to resolve the harmful interference being
   caused by your BDA systems to the QVC Studio and Cherry Hill High School
   East within that time period may subject you to severe penalties,
   including, but not limited to, substantial monetary fines, in rem arrest
   action against the offending equipment, and criminal sanctions including
   imprisonment. (see 47 U.S.C. SS 401, 501, 503, and 510).

   Pursuant to Sections 4(i), 4(j), 308(b) and 403 of the Act, you are
   directed to provide, in writing, within ten (10) days from the date of
   this Warning Notice, a report detailing the steps taken to resolve the
   interference at the QVC Studio and Cherry Hill High School East and a
   detailed plan for resolving in a timely manner any future incidents of
   harmful interference caused by Sprint's BDA systems. The report and plan
   should be submitted to the following address:

   The Privacy Act of 1974 requires that we advise you that the Commission
   will use all relevant material information before it, including any
   information disclosed in your reply, to determine what, if any,
   enforcement action is required to ensure compliance. Any false statement
   made knowingly and willfully in reply to this Warning Notice is punishable
   by fine or imprisonment under Title 18 of the U.S. Code.

   Section 90.7 of the Rules defines a signal booster as: "A device at a
   fixed location which automatically receives, amplifies, and retransmits on
   a one-way or two-way basis, the signal received from base, fixed, mobile,
   and portable stations, with no change in frequency or authorized
   bandwidth. A signal booster may be either narrowband (Class A), in which
   case the booster amplifies only those discrete frequencies intended to be
   retransmitted, or broadband (Class B), in which case all signals within
   the passband of the signal booster filter are amplified." 47 C.F.R. S
   90.7. Sprint's signal boosters are Class B and therefore subject to the
   requirement  that they only be used where there is little or no risk of
   interference to other users.  See 47 C.F.R. S 90.219(d).
