59rd Meeting of FM22 Copenhagen / Web Meeting, 28 – 31 March 2023
Date: 23 March 2023

Subject: MFCN field strength control in border areas
Group membership required to read: N
Summary: When monitoring MFCN fields strength levels for non-AAS BS in the border areas, it is proposed to measure average/mean field strength in logarithmic scale in order to compare that with the levels defined in ECC Recommendation (15)01. Some additional elements, i.e. averaging time of measurements and how to account for network loading (traffic) also needs to be taken into account.
Proposal: FM22 is invited based on the material to discuss the following: To measure average/mean field strength in logarithmic scale; To use at least 360 s averaging time when measuring the average value of the field strength; In case received signal power is measured instead of field strength, the correction of 10 dB should be applied in order to account for network loading. Participants are also invited to share their monitoring practice for measuring the field strength levels created by MFCN in the border areas.
Background: ERC/ECC recommendations regarding cross-border coordination for MFCN. At the 58th meeting of FM22 it was decided that in cooperation with Latvia and Lithuania, Germany will start to develop a first draft of a new ECC Recommendation on MFCN field strength measurements at the border areas.
Introduction: The FM22 group is currently drafting a new ECC recommendation “Field strength measurements of Mobile/Fixed Communications Networks (MFCN) in border areas in the frequency range 790-3800 MHz”. The main purpose of this recommendation is to unify the methods for measuring field strength in border areas between neighbouring countries. These measurements are used to check compliance with the field strength limits given in cross-border recommendations as well as in bilateral/multilateral agreements between the administrations or operators of neighbouring countries. Moreover, the field strength limits in the agreements are usually rewritten from the relevant recommendations. As for the field strength measurements, the situation with the definition of field strength seems somewhat ambiguous. For example, the ECC Recommendation (15)01 defines mean values for non-AAS BS and median values for AAS BS. But the limits are usually interpreted as the maximum values of the field strength.
Derivation of the field strength limits for cross-border: The field strength limits are obtained through computer simulation. Here, the interference from one network to another is simulated. The field strength limit is obtained for the acceptable throughput loss. For simulation, the software tool SEAMCAT is used, which is based on the Monte-Carlo simulation method developed within the frame of CEPT.
Difficulties in monitoring the field strength limits: The averaged field measurements depend noticeably on the averaging time. It seems reasonable to take the averaging time long enough to obtain reproducible results of the measured average value. In the case of LTE, this averaging time will be around 360 s. It should be noted that this average value will be noticeably less than the maximum values of the field strength. Averaged field strength also depends on the traffic. The measurements are carried out for the power of one resource element in the PBCH and then extrapolated to a full traffic situation.
