5G Roll Out Impact REPORT

Very large exclusion zone due to unrealistic power – may lead to substantial 5G deployment challenges
IEC 62232 (2017) and ITU-T K.100 standards open up for use of actual maximum output power (95th percentil)

Massive MIMO and beamforming:

  • More complex EMF compliance assessments
  • Potentially higher EIRP and larger EMF compliance boundaries (exclusion zones) than for conventional antennas if theoretical maximum power is used for all beams
  • Site design of increasing importance – especially in countries using limits lower that ICNIRP guidelines

Frequency bands above 10 GHz:

  • EMF assessment methodology and standards available but need to be further refined
  • International EMF limits more conservative in the nearfield which may lead to larger compliance distances for small cell base stations

Conclusions:

  • EMF compliance may be a challenge for 5G massive MIMO sites if assuming theoretical maximum power for all beams
  • International standards IEC 62232 and ITU-T K.100 open up for use of actual maximum power to perform realistic EMF compliance assessments
  • Statistical model to determine actual maximum power of 5G massive MIMO antennas has been developed: found to be around 25% of theoretical maximum power for 8×8 array antennas
  • In countries with EMF limits significantly below the international science-based ICNIRP limits the roll-out of 5G networks will be a major problem
  • Very large exclusion zone due to unrealistic power – may lead to substantial 5G deployment challenges
    IEC 62232 (2017) and ITU-T K.100 standards open up for use of actual maximum output power (95th percentile)
