G NR base station analysis
In 5G NR, the concept of the “beam” is defined. The SSB is sent in a period of 20ms (default), and 8 (or 4) SSBs are transmitted in the first 5ms of each 20ms. Each SSB represents a Beam and is sent to a different direction. E8900A can test the physical cell ID (PCI) of the base station and the beam ID and power (SS-RSRP) of the current location.
5G NR drive test
test the signal intensity coverage of the 5G base station, and the 5G road test is divided into indoor test and outdoor drive test.
The parameters such as PCI, Beam ID and SS-RSRP obtained at each test point are automatically saved.
