Can broadband equipment be used to measure EMF field level?Thus, broadband equipment can still be used for assessing the EMF field level when measurements are done by forcing an extra load of the station, as it uses to overestimate the field levels. The largest differences in the values measured by the different methods happen at location 7, and especially at location 4.
Do 5G base stations need a field meter?Fast variation of the user load and beamforming techniques may cause large fluctuations of 5G base stations field level. They may be underestimated, resulting in compliance of base stations not fitting the requirements. Apparently, broadband field meters would not be adequate for measuring such environments.
Does a 5G base station increase field levels?Adding the 5G systems does not significantly increase the overall field levels in the surroundings of the base station, in normal working conditions, compared to those of the previous generation. This has been checked during a measurement campaign in the surroundings of a 5G base station under operation.
How many subcarriers does a 100 MHz SSB occupy?If we have a 100 MHz bandwidth signal with a 30 kHz SCS and an FDD scheme, our available resources will be 3,300 subcarriers (100 MHz/30 kHz) in frequency and 280 symbols per frame in time (20 slots per frame and 14 symbols per slot). Thus, the SSB, when transmitted every 10 ms, will occupy a 0.1 % of the resources.
Can broadband field probes assess 5G base stations compliance?This paper analyzes the feasibility of assessing the 5G base stations compliance using broadband field probes and compares their performance with alternative methodologies and equipment.
Why is RBW set to 30 kHz?The base station used for the experiment, transmits a 5G signal with an SCS of 30 kHz, therefore, in order to differentiate the subcarriers, RBW is set to 30 kHz. The measurement time per frequency point should be longer than the length of the SSB (143 μ
