Ericcson 6701

Ericsson Street Macro 6701-B261

Link to 2019-0919 FCC EMF Test Report

Main Features

The main features of the Streetmacro 6701 are the following:

  • Vertical and horizontal analog beamforming
    • +/- 60 degrees in azimuth and
    • +/- 15 degrees elevation
  • Supports two beams in config mode 2
  • Supports four beams in config mode 1
  • Power supply: 100–250 V AC
  • Fan cooling
DescriptionValue
FrequencyB261 (27,500–28,350 MHz)
Number of carriersConfig mode 2: Up to 8
Config mode 1: Up to 16
Operating bandwidthConfig mode 2: 800 MHz
Config mode 1: 1600 MHz
Component carrier bandwidth50MHz, 100 MHz
EIRPConfig mode 2: 53 dBm per RF beam in boresight 56 dBm per radio
Config mode 1: 47 dBm per RF beam in boresight , 53 dBm per radio

Frequency range = 27,500–28,350 MHz

RF Microwave Radiation
out-of-compliance area = a box the size of
about 5 full-size refrigerators!

Per this calculator, 56dBm = 398 Watts/Beam x 2 Beams = 796,000,000 µWatts

This is 80x-200x higher than the FCC’s RF Microwave radiation limit of 4,000,000 to 10,000,000 µWatts/m²


Conclusion

The Ericsson Street Macro 6701 B261 has been tested using methods and procedures specified in FCC OET Bulletin 65 [3] and IEC 62232:2017 [4]. The results in Section 5 show the compliance boundary dimensions for the considered configuration of the product. Outside of these compliance boundaries, the RF exposure is below the limits specified in [1].
