Please explain in the area below why an STA is necessary:
Panasonic Avionics Corporation (Panasonic) requests an experimental Special Temporary Authority (STA) commencing on or about September 10, 2011 to conduct ground testing in support of Panasonic?s Global Communications Suite (GCS) featuring the eXConnect Ku-band aeronautical mobile-satellite service (AMSS) system to provide broadband connectivity onboard aircraft in flight. On November 2, 2010, the FCC granted a two-year experimental license (Call Sign WF2XLF), effective until November 1, 2012, to conduct two types of testing at four sites: (1) electromagnetic interference (EMI) ground testing of multiple, simulated transmit portable electronic devices (T-PEDs) RF transmissions in the aircraft cabin in multiple frequency bands: GSM, cellular, Wi-Fi and others; and (2) picocell system operations in the aircraft cabin for enabling GSM phone communications for passengers and crew. Subsequently, the FCC granted two additional experimental STAs for further testing at two other sites (Call Sign WE9XMG and Call Sign WE9XVM). As further described in the accompanying Narrative Statement, Panasonic is seeking the instant experimental STA to conduct ground testing at Paine Field Airport, Everett, WA. Although Call Sign WF2XLF already grants authority to conduct both T-PED EMI and picocell system tests at this site, Panasonic has determined there is a need to conduct T-PED EMI tests in other Wi-Fi frequency bands at 2.4 GHz and 5 GHz at Paine Field Airport not previously authorized pursuant to this two-year experimental license. The proposed testing will be limited to T-PED EMI testing; accordingly, Panasonic is not seeking authority to conduct picocell system testing in the instant application.
