By the Regional Director, Region One, Enforcement Bureau:

1. This is a Notice of Violation (Notice) issued pursuant to Section 1.89 of the Commissions rules (Rules) 47 CFR  1.89.
 to Stone Springs Hospital Center, owner of signal booster # SB0003172 in Dulles, Virginia.  Pursuant to Section 1.89(a) of the Rules, issuance of this Notice does not preclude the Enforcement Bureau from further action if warranted, including issuing a Notice of Apparent Liability for Forfeiture for the violation noted herein. 47 CFR  1.89(a).  

2. On May 31, 2018 agents of the Enforcement Bureaus Columbia Office investigated a complaint of interference and determined that the source was a signal booster located at the Stone Springs Hospital Center, 24440 Stone Springs Blvd., Dulles, VA 20166.  The signal booster was a Cellular Specialties Inc. Bi-Directional Amplifier (BDA), Model CSI-T51080-SP78.  On behalf of Stone Springs Hospital Center, CellAntenna Corporation registered the signal booster in the Commissions Part 90 Class B Signal Booster Registration Database under Signal Booster ID SB0003172. The signal booster was operated in the Stone Springs Hospital Center as part of the Loudoun Countys 800 MHz radio trunk system with call signs WPQZ390, WPRS263, WQCT758 and WQCT759.  
  The agents inspected signal booster # SB0003172 and observed the following violations:

47 CFR  90.219(d)(6) of the Rules:Good engineering practice must be used in regard to the radiation of intermodulation products and noise, such that interference to licensed communications systems is avoided.  In the event of harmful interference caused by any given deployment, the FCC may require additional attenuation or filtering of the emissions and/or noise from signal boosters or signal booster systems, as necessary to eliminate the interference . . . .  In general, the ERP (Effective Radiated Power) of the noise within the passband should not exceed -43dBm in 10 kHz measurement bandwidth.  At the time of the investigation, Stone Springs Hospital Centers signal booster was generating spurious emissions in the 800 MHz band which exceeded the ERP limit and caused harmful interference to the Metropolitan Washington Airport Authoritys Land Mobile Radio Service Station WPAY961.  Thus, Stone Springs Hospital Center is in violation of section 47 C.F.R.  90.219(d)(6) of the Rules.

3. Pursuant to Section 308(b) of the Communications Act of 1934, as amended, 47 U.S.C.  308(b).
 and Section 1.89 of the Rules, we seek additional information concerning the violations and any remedial actions taken.

The response (i) must fully explain each violation, including all relevant surrounding facts and circumstances, (ii) must contain a statement of the specific action(s) taken to correct each violation and preclude recurrence, and (iii) must include a time line for completion of any pending corrective action(s).  The response must be complete in itself and must not be abbreviated by reference to other communications or answers to other notices. 47 C.R  1.89(c).
