NOTICE OF VIOLATION
Released: July 26, 2010  
By the District Director, Philadelphia Office, Northeast Region, Enforcement Bureau:
1. This is a Notice of Violation (“Notice”) issued pursuant to Section 1.89 of the 
Commission’s Rules1 to USA Mobility Wireless, Inc. (“USA Mobility”), the licensee of 
station WPSG659 in Philadelphia, Pennsylvania.  
2. On May 26, 2010, the Commission’s Philadelphia Office received a complaint from 
Cellnet Technology Northeast, Inc. (“Cellnet”), the licensee of station WPNE497, 
alleging that its wireless meter reading system in Philadelphia, Pennsylvania was 
experiencing harmful interference on the frequency 928.3125 MHz.  In response to the 
complaint, on May 28, 2010, agents of the Commission’s Philadelphia Office inspected 
radio station WPSG659 located at the Saint Christopher’s Hospital for Children in 
Philadelphia, Pennsylvania and observed the following violation:      
47 C.F.R. § 22.359(a):  “The power of any emission outside of the authorized 
operating frequency ranges must be attenuated below the transmitting power 
(P) by a factor of at least 43 + 10 log (P) dB.”2 At the time of the inspection, 
agents found that USA Mobility’s 929.6125 MHz paging transmitter was 
generating a spurious emission on the frequency 928.3135 MHz that 
exceeded the emission mask limit by 24 dB3.  The Philadelphia Office found 
that the spurious emission on 928.3125 MHz was causing harmful 
interference to Cellnet’s wireless meter reading system.  
  
1 47 C.F.R. § 1.89.
2 According to Section 90.493(b) of the Commission’s Rules, 47 C.F.R. § 90.493(b), paging operations on exclusive 
channels in the 929-930 MHz band, such as station WPSG659, are subject to the licensing, construction and operation 
rules of Part 22.    
3 The FCC measured the level of the spurious emission to be -67 dBm.  The level of the fundamental was measured to 
be -24 dBm; a difference of 43 dB.  Based on the transmitter output power of 250 Watts, the spurious emission should 
be attenuated at least 67 dB below the authorized transmitting power.
