What does the host of communication equipment mainly mean?
The host of communication equipment refers to the base station. For Acer (BBU+RFU) and distributed base station (BBU+RRU).
A distributed base station is an independent base station. Repeaters must rely on base stations.
You say the base station, it will not call the host. Acer is the main station BBU+RFU, distributed base station is generally BBU+RRU. The near - end machine and the remote machine are the concepts of the repeater station. BBU+RRU is an independent base station. Repeater stations must rely on base stations. Do not make a right and for example: BBU+RRU/RFU is a source of words (radio resource), or no light in one place, the periscope (his own not to light source) here is equivalent to the repeater, he just put the wireless resources to transfer, as the district are not what increase. The near end machine refers to the side of the communication with the base station, the remote machine refers to the side of the communication with the UE. BBU mainly deals with baseband signals, and RRU/RFU is mainly part of radio frequency. Chinese is not very good, maybe I said so, you are more confused
In base station, BBU mainly deals with baseband signals, while RRU and RFU are mainly responsible for radio frequency components.
