CONFIDENTIAL AND PROPRIETARY For Internal Use Only - Do Not Duplicate Copyright (c) 2009 by Motorola 9The Orthus radio shall be designed to meet IEEE recommendation for spectrum mask. For the 20MHz operation, the spectrum mask will conform the IEEE standard in 802.11n draft 2.0 as defined in 21.3.20.1. Please refer to the draft 2.0 for more details. Figure 6-20MHz spectrum mask When transmitting in a 20 MHz channel, the transmitted spectrum shall have a 0 dBr (dB relative to the maximum spectral density of the signal) bandwidth not exceeding 18 MHz, –20 dBr at 11 MHz frequency offset, –28 dBr at 20 MHz frequency offset and –45 dBr at 30 MHz frequency offset and above. The transmitted spectral density of the transmitted signal shall fall within the spectral mask, as shown in Figure n64 (Transmit spectral mask for 20 MHz transmission). The measurements shall be made using a 100 kHz resolution bandwidth and a 30 kHz video bandwidth. The mask for 40MHz RF signal is shown below: Figure 7-40MHz spectrum mask
CONFIDENTIAL AND PROPRIETARY For Internal Use Only - Do Not Duplicate Copyright (c) 2009 by Motorola 102.6.2 Spectral flatness The transmit spectral flatness will conform the 802.11n draft as specified in section 20.3.20.2. In a 20 MHz channel and in corresponding 20 MHz transmission in a 40 MHz channel, the average energy of the constellations in each of the spectral lines –16 to –1 and +1 to +16 shall deviate no more than ± 2 dB from their average energy. The average energy of the constellations in each of the spectral lines –28 to –17 and +17 to +28 shall deviate no more than +2/–4 dB from the average energy of spectral lines –16 to –1 and +1 to +16.In a 40 MHz transmission (excluding HT duplicate format and non-HT duplicate format) the average energy of the constellations in each of the spectral lines –42 to –2 and +2 to +42 shall deviate no more than ± 2 dB from their average energy. The average energy of the constellations in each of the spectral lines –43 to –58 and +43 to +58 shall deviate no more than +2/–4 dB from the average energy of spectral lines –42 to –2 and +2 to +42.2.6.3 Transmit power range and accuracy This radio will have an adjustable output power range from +4dBm to +28dBm in 0.5 dB step. Per Atheros radio calibration procedure as well as per base band chipset design, this radio shall be designed to maintain an averagetransmit power accuracy of +/-2dB per antenna. The method for determining the average transmitted power accuracy is calculated as follows: When the ideal transmitted power is set by software, the output RF power of the radio is measured simultaneously by the MIMO Litepoint Iqnxn test set (or equivalent) for a given data rate on all channels, all frequency bands. The actual measured output power is subtracted from the ideal settings to obtain the errors for each level. The errors at each level are then averaged over all channels in the given band. This calculation shall be performed for each transmit chain. 2.6.4 Transmit center frequency tolerance The transmitter center frequency tolerance shall be ±20 ppm maximum. 2.6.5 RX Symbol clock frequency tolerance This table below lists the minimum requirements for the radio by the IEEE standard. The actual radio shall be able to accommodate +/- 50ppm.

CONFIDENTIAL AND PROPRIETARY For Internal Use Only - Do Not Duplicate Copyright (c) 2009 by Motorola 142.6.12 Conducted transmit power Due to the EVM and side-lobe requirements, the maximum transmit power will vary with data rates. The figures below shows typical transmit power for each transmitted chain for both 2.4GHz and 5.2GHz operation. The transmit power listed here are characterized based on EVM purpose only. The final AP transmit power depends on the result of regulatory test for each country. As mentioned in beginning of the document, the radio has two modes: 3.3V and 5.0V mode. The transmit power for 5.2G is the same in both modes whereas the transmit power for the 2.4G band is boosted. The two tables below lists the difference. The conducted transmit power is specified as the power measured at the Orthus radio connector and not at the antenna chassis of the AP. Average transmit power is a number typically seen when measured on an arbitrary radio.

However, the radio interception point will be measured, and calculated. The receiver interception point should reflect an acceptable performance for normal usage of the Orthus AP. 2.7.6 Receiver channel power indicator (RCPI) The receive channel power indicator also known as RSSI definition is described as follows. The RCPI indicator is a measure of the received RF power in the selected channel. This parameter shall be a measure by the PHY sublayer of the received RF power in the channel measured over the entire received frame. The received power shall be the average over all receive chains. RCPI shall be a monotonically increasing, logarithmic function of the received power level defined in dBm. The allowed values for the Received Channel Power Indicator (RCPI) parameter shall be an 8 bit value in the range from 0 through 220, with indicated values rounded to the nearest 0.5 dB as follows: — 0: Power not > -110 dBm — 1: Power = -109.5 dBm — 2: Power = -109.0 dBm — and so on up to — 220: Power not < 0 dBm — 221-254: reserved — 255: Measurement not available where RCPI = int{(Power in dBm +110)*2} for 0 dbm > Power > -110 dBm (21-76) Accuracy for each measurement shall be +/- 5dB (95% confidence interval) within the specified dynamic range of the receiver. The measurement shall assume a receiver noise equivalent bandwidth equal to the channel bandwidth multiplied by 1.1.

RF exposure 20 cm statement This device complies with FCC radiation exposure limits set forth for an uncontrolled environment. In order to avoid the possibility of exceeding the FCC radio frequency exposure limits, human proximity to the antenna shall not be less than 20cm during normal operation. Antenna Installation information Reference antennas have been used during the approval process for the radio card. Specific details of the reference antenna used for testing is detailed in the table below. Important Note: Use of an antenna which is the same ‘type’ (eg. Dipole) and has a gain equal to or less that the reference antenna can be used without recertification. Note: The Adapter cable must be considered as it is part of the system gain. Use of an alternative antenna, different ‘type’ or same ‘type’ but higher gain will invalidate the country approvals. Under this instant the system integrator is responsible for re-evaluating the end product and obtaining separate approvals. Part 15.21 user warning Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment.Part 15.19 a 3 This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device
must accept any interference received, including interference that may cause undesired operation.Part 15.105 B This device has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiated radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: -Reorient or relocate the receiving antenna. -Increase the separation between the equipment and receiver. -Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.-Consult the dealer or an experienced radio/TV technician for help.
