Introduction Transmit OOB emission requirement is specified in terms of transmit spectral mask and maximum transmit OOB emission. At low transmit power, the OOB emission is specified in terms of maximum transmit OOB emission.
Transmit OOB Emission specification for 11a and 11n IEEE 802.11a specified maximum OOB emission as -53dBm / MHz, 30MHz from the center frequency Above 0dBm transmit power OOB emission is specified according to spectral mask (-40dBr @ 30 MHz from fc) Below 0dBm transmit power OOB emission should not exceed -53dBm/MHz IEEE 802.11n specifies maximum OOB emission as -53dBm/MHz, 30 MHz from center frequency for 20MHz transmission Above 5dBm transmit power OOB emission is specified according to spectral mask (-45dBr @ 30 MHz from fc) Below 5 dBm transmit power OOB emission should not exceed -53dBm/MHz IEEE 802.11n specifies maximum OOB emission as -56dBm/MHz, 60 MHz from center frequency for 40MHz transmission Above 5dBm transmit power OOB emission is specified according to spectral mask (-45dBr @ 60 MHz from fc) Below 5 dBm transmit power OOB emission should not exceed -56dBm/MHz
Proposed maximum OOB emission levels for TGac Propose that the spectral mask requirement for TGac be modeled based on 11a spectral mask requirement Devices that support TGac could also support 11a and 11n For 20MHz TGac transmission Above 0dBm transmit power OOB emission is specified according to spectral mask (-40dBr @ 30 MHz from fc) Below 0dBm transmit power OOB emission should not exceed -53 dBm/MHz For 40MHz TGac transmission Above 0dBm transmit power OOB emission is specified according to spectral mask (-40dBr @ 60 MHz from fc) Below 0dBm transmit power OOB emission should not exceed -56 dBm/MHz
Proposed maximum OOB emission levels for TGac For 80MHz TGac transmission Above 0dBm transmit power, OOB emission is specified according to spectral mask (-40dBr @ 120 MHz from fc) Below 0dBm transmit power, OOB emission should not exceed -59 dBm/MHz For 80 + 80 MHz and 160 MHz TGac transmission Maximum transmit OOB emission for 80+80 should be the same as for 80MHz. Requirements for 160 MHz same as 80+80 Above 3dBm transmit power OOB emission is specified according to spectral mask (-40dBr @ 120/240 MHz from fc) Below 3dBm transmit power OOB emission should not exceed -59 dBm/MHz
Pre-motion #1 Move to insert the following requirements for maximum transmit OOB emission to the spec framework? Add to Table 6--Transmit spectral mask for various BW PPDUs, “Maximum transmit OOB emission” with the following values 20 MHz -53 dBm/MHz, if transmit power is below 0dBm 40 MHz -56 dBm/MHz, if transmit power is below 0dBm 80 MHz -59 dBm/MHz, if transmit power is below 0dBm 80+80 and 160 MHz -59dBm/MHz, if transmit power is below 3dBm -Yes -No -Abstain
