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
| Description | Value |
|---|---|
| Frequency | B261 (27,500–28,350 MHz) |
| Number of carriers | Config mode 2: Up to 8 Config mode 1: Up to 16 |
| Operating bandwidth | Config mode 2: 800 MHz Config mode 1: 1600 MHz |
| Component carrier bandwidth | 50MHz, 100 MHz |
| EIRP | Config 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!
Based on this 28 cubic ft refrigerator
| Out | Width | Height | Volume |
|---|---|---|---|
| 1.8 m | 2.1 m | 1.0 m | 3.8 cubic m |
| 5.9 ft | 6.9 ft | 3.3 ft | 134.4 cubic ft |
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].
