Federal Communications Commission 849 NW State Road 45 Equipment Approval Services Newberry, FL 32669 P.O. Box 35815, Pittsburgh, PA 15251-3315 Applicant: Dynastream Innovations, Inc. Equipment: FCC ID: O6RSDM4 228 River Avenue CORES number: 0008-0335-57 Cochrane, Alberta FCC Rules: Parts 2 and 15.249 Canada T4C 2C1 Re: Class 2 permissible change (increase frequency band of operation) Gentlemen: Please process the attached application for Class 2 permissible change increasing frequency band of operation to 2403-2480 MHz. The form 731 and supporting application information have been electronically submitted and any attachments will be up loaded to your web site to be used in obtaining a grant of certification in compliance with Class 2 permissible change of authorized equipment. Per KDB 178919 paragraph 4 the following points are addressed here and in supporting documentation. 4. Software changes: Class I and Class II software changes for non-SDR approved devices - the following software only changes are allowed: a) Additional frequencies may be added to an approved device under the following conditions; however, a new test report must be submitted for the new frequencies: i. Additional frequencies are allowed with a Class II permissive change if: 1. No hardware changes have been made to the design. 2. There is no increase in output power rating on new frequencies as demonstrated in report. 3. The Equipment Class remains the same as previously certified. 4. RF exposure changes are addressed in MPE exposure calculation exhibit. 5. Only the Original Equipment Manufacturer may implement the new frequencies. 6. There are no other changes to the device that indicate a need for a new FCC ID. ii. End user software implementation for new frequencies is not allowed unless the device was approved as a software-defined radio. (Class III permissive change rules for software defined radios are in Section 2.1043(b)(3)). b) No new line items are required. Adding new line items on the Form 731 is allowed under a Class II permissive change. Additional data rates (both higher and lower rates) under existing modulations that are consistent with a Form 731 line item/emission designator may be either a Class I or Class II, depending on emissions. A Class II permissive change is required if degradation occurs; if no degradation occurs a Class I permissive change is acceptable.

z Page 2 June 10, 2010 c) Output power remains as previously authorized. A Class II permissive change for a device with a decrease in output power, or with a different field strength, is allowed under the following conditions: The maximum output power rating of the original authorization does not change. There is no design change that increases or decreases the output power. A decrease in the power setting configuration is acceptable. In no case, may a power limit be exceeded. Should you require any further information, please contact the undersigned. Thank you for your consideration in this matter. Sincerely, Scot Rogers Rogers Labs, Inc. Enclosures
