FCC ID:

To Whom It May Concern:

Pursuant to the provisions of Sections 0.457 and 0.459 of the Commissions rules (47 CFR 0.457, 0.459), we are requesting the Commission to withhold the following attachments as confidential document from public disclosure indefinitely. Schematic Diagram Block Diagram Operational Description Internal Photos User Manual Antenna Specification The transmitter is a Base Station where the access is controlled and only available to trained personnel. We request that the internal photos be kept confidential long-term under the FCC guidelines that this is a non-consumer device (Base Station) and is serviceable by employees and subcontractors of SmartSky, with all service personnel subject to non-disclosure agreements. The user manual is requested to remain confidential long-term under the FCC guidelines that the manual is very technical and is not provided to the general public. The user manual contains proprietary information used by trained technicians to service the devices. All technicians will be subjected to non-disclosure agreements. Furthermore, the block diagrams, schematics, parts list antenna specification and operational description are requested to be confidential long-term under the FCC guidelines since our design incorporates a software-defined radio architecture which is innovative and proprietary to SmartSky. SmartSky has spent substantial effort in developing this product and is one of the first of its kind in the industry. Having subject information easily available to competitors would negate the advantage SmartSky has achieved by developing this product. Not protecting the details of design will result in financial hardship. 430 Davis Drive, Suite 350, Morrisville, NC 27560 Page 1 of 2 DocuSign Envelope ID: 9DC76940-3162-430A-9705-2E231D6FCB89 In additional to above mentioned documents, pursuant to Public Notice DA 04-1705 of the Commissions policy, we are requesting the commission to grant short-term confidentiality request on the following for One Hundred Eighty (180) days from the date of the grant.
