Hi All, The ECC (14)BB http://www.cept.org/ecc/tools-and-services/ecc-consultation text (page 8) being commented on: A2.1.1
In-block requirements for MFCN base stations §
2300-2400 MHz: An in-block e.i.r.p. limit is not obligatory. In case an upper limit is desired by an administration, a value which does not exceed 68 dBm / 5MHz e.i.r.p. per
antenna may be applied. For the protection of WLAN above 2400 MHz, administrations may need to apply more stringent in-block e.i.r.p. limit in the upper part of the band 2300-2400 MHz. The Ofcom consultation for this band proposes to limit 2390-2400 MHz to 61 dBm/5 MHz, but there remains the possibility that RLAN operation on channel 1 will be blocked by LTE base station operation in 2380-2390
MHz. 2300MHz-2400MHz into RLAN sharing analysis is presented in ECC Report 172, section 6.2, page 67 http://www.erodocdb.dk/docs/doc98/official/pdf/ECCRep172.pdf
Note ECC Rep 172 Annex A.1.3 Unwanted Emissions Mask (Table 64, page 82) Rather that limiting the power only in 2390 to 2400 (2 x 5 MHz channels), I extended that to 4 channels (2380 – 2400 MHz). The reason is that report 172 indicates a high probability of interference into outdoor 802.11
networks. (82% for WLAN operating on 2412 and still 16% for WLAN operating on 2432 MHz).
Note that the 1st channel (20 MHz wide with 2412 as centre) is from 2402 up to 2422 MHz. So just doing something on the upper 10 MHz of 2300 band is not sufficient.
Please look at the reference documents and come to 802.11REG AM2 CW-L1 Function 12 prepared to discuss an 802.11 comment to be taken forward. Thanks in advance, petere From: *** Regulatory and Spectrum Allocation Topics *** [mailto:STDS-802-11-REG@xxxxxxxx]
On Behalf Of Peter Ecclesine (pecclesi) My colleague Edgard Vangeel wrote to TG11: This is a reminder on the below Public Consultations currently going on regarding the 2.3 GHz band (adjacent to the 2.4 GHz band being used by WIFI, Bluetooth, Zigbee, etc…)
1.
OFCOM Here is the link to the OFCOM public consultation on coexistence between 2.3 GHz LTE and 2.4 GHz WIFI. http://stakeholders.ofcom.org.uk/consultations/pssr-2014/
2.
ECC The ECC public consultations can be found here: http://www.cept.org/ecc/tools-and-services/ecc-consultation That one includes the public consultation on the ECC Decision on ‘Harmonised technical and regulatory conditions for the use of the band 2300-2400 MHz for MFCN’. If you have concerns about a possible negative impact of the deployment of LTE in 2.3 GHz on EN 300 328 type of applications in 2.4 GHz band, you can use the above URLs to raise your concerns.
