Definitions
- the present invention relates to the field of mobile communications, and in particular to an active distributed antenna system relay terminal and an active distributed antenna system.
- LTE network standards such as TD-LTE and FDD-LTE
- SISO single input single output
- MIMO Multiple-input Multi- Output, multiple input multiple output
- SISO coverage is first carried out, and subsequent MIMO coverage schemes are upgraded.
- DAS relays only support one of SISO mode or MIMO mode and are not configurable.
- customers are building 4G (fourth generation mobile communication technology) networks, they need to select different DAS trunking machines according to different schemes. If they need to be upgraded to MIMO by SISO, only equipment replacement can be performed, which greatly increases the network construction cost. .
