Correct installation also optimises receive signal strength and system performance. The User manual modifiedas follows: The following additional paragraph will be added to page 3: RG211-3.8 CPE compliance with FCC 47CFR90Z: RG211-3.8 (FCC ID:V8YFW181RG38002W) is certified by the FCC as Fixed Equipment and may only be installed by suitably trained personnel acting on behalf of the FCC license holder. “Location selection” sectionon page 20 will be removed. “Mounting on Horizontal Surface” sectionon page 21 will be removed. Yours Sincerely Charlie Blackham Director

For the purpose of testing, the CPE was put into a test mode which required custom settings of certain parameters and for the CPE to be controlled via its serial port which is accessed via a header on the PCB once the cover is removed. No information on these parameters, nor the correct wiring of the serial port, nor the commands required to enable test mode transmissions are available to the end user. The CPE is fixed, but only operates only under the authorisation of its associated WiMAX basestation. As WiMAX uses a scheduled air-interface protocol,a CPErequires Media Access Protocol information from the Base Station in order to schedule uplink transmissions for each frame it transmits. In the case the Base Station ceases transmission; the Subscriber Station will receive no MAP information, and therefore will not transmit any signals. The Subscriber Station contention based protocol compliance requirements are therefore met by the correct use of an appropriate, FCC certified, WiMAX basestation. In order for this to hold true, this fixed CPE acts like mobile and portable stations in that 90.1333 applies and it will operate only if it can positively receive and decode an enabling signal transmitted by a base station. Yours Faithfully Charlie Blackham

The antenna specification “Ant_120300000039W_19-AN3700- 1901RS.Spec.09.09.10.pdf” states that the antenna gain is 5dBi nominal with permitted variation of ‚0.7dB. The stated value of antenna gain in the test report of 6dBi is the maximum possible antenna gainvalue of 5.7 dBi rounded up to the nearest whole dB. Yours Sincerely Charlie Blackham Director
