RF-EMF Exposure for sub-6GHz 5G NR Massive MIMO Base Station

Abstract

RF-EMF Exposure for sub-6GHz 5G NR Massive MIMO Base Station Sali A, Wali AQ, Osman AF. Evaluation of RF-EMF Exposure for sub-6GHz 5G NR Massive MIMO Base Station. 2022 IEEE 6th International Symposium on Telecommunication Technologies (ISTT), 2022, pp. 16-21, doi: 10.1109/ISTT56288.2022.9966552. Abstract The 5G network is intended to accommodate a significant quantity of mobile data traffic and a great number of wireless connections. It improves cost and power consumption; it offers ultra-low latency and ultra-high dependability to enable new services in various sectors. However, the general public is concerned about the possible health dangers linked with 5G equipment's Radio Frequency (RF) radiation, and numerous localities are actively lobbying to prevent 5G implementation. This research measures the maximum exposure emitted by a 5G base station operating on 3.5 GHz. Considering the transmitted power changes over time with data traffic, the analysis is based on a code selective method. Measurements were conducted at two different distances and three different times to investigate the impacts of distance and time on the level of RF-EMF radiation. The maximum radiation from the base station is 11.69 V/m, far less than the accepted limit by the ICNIRP standard. ieeexplore.ieee.org

Main findings

Measurements of a 5G base station operating at 3.5 GHz were conducted at two distances and three times using a code selective method. The maximum reported radiation level was 11.69 V/m, stated to be far below the ICNIRP accepted limit.

Outcomes measured

• RF-EMF exposure level (electric field strength, V/m)
• Comparison to ICNIRP limit

Limitations

• No health outcomes were assessed; study focuses on exposure levels only.
• Distances and specific measurement times are not reported in the abstract.
• Sample size/number of measurement points and measurement protocol details are not provided in the abstract.
• Only one frequency band (3.5 GHz) and a single base station context are described in the abstract.

Suggested hubs

• 5g-policy (0.78)
