Base Station Base Station (BS) is a key component of the 5G Radio Access Network (RAN) architecture that serves as an access point for wireless connections between user equipment (UE) and the network. It consists of a radio unit and an antenna system that transmits and receives signals to and from the UE.
This agrees with measurements done in other countries whose authors conclude that the exposure to 5G signals is limited , , , but this does not assure the base station compliance as full load situation should be considered for such assessment. It also shows that the increase in the EMF field is due to the induced data traffic.
In conjunction with 5G NR, private base stations (BS) can support connectivity for different spectrum bands (sub-GHz, 1 to 6 GHz, or mmWave). The 5G base station products must pass all of the test requirements prior to their release. Otherwise, the products are not 3GPP-compatible or appropriate to implement in a network.
When adding 5G radios and antennas to an existing base station site, the total RF EMF exposure from all antennas and technologies (2G, 3G, 4G, and 5G) has to be considered for assessment of compliance with limits and regulations. Figure 2.
This page provides an overview of 5G measurements performed on User Equipment (UE) and Base Stations (BS) or Nodes B (NB). It details both 5G UE measurements and 5G BS measurements. The 5G measurements encompass both transmitter and receiver test scenarios. Introduction: The following tests are generally performed during 5G measurements:
