Abstract
A 5G distributed system includes a near-end unit, a remote device, and an active antenna unit. The near-end unit transmits signals of multiple modes including 5G signal to the remote device. The remote device performs frequency conversion processing on 5G signal and does not perform frequency conversion processing on signals of other modes, such as 4G, and then outputs to the active antenna unit for coverage. In the present disclosure, the 5G signal is converted by frequency conversion at the remote device, and signals of other modes other than 5G signal are transmitted to the remote active antenna unit without being processed by frequency conversion for signal coverage, which satisfies the coverage requirements of 5G indoor distribution.
Claims16
A remote device, comprising:
- a remote unit including:
- at least one remote frequency conversion processing unit, configured to perform frequency conversion processing or restoration frequency conversion processing on a first signal and output the processed first signal, and the first signal including 5G signal;
- and
- at least one remote non-frequency-conversion processing unit, configured to directly output a second signal without being processed by frequency conversion, the second signal including one or more of 2G signal, 3G signal, or 4G signal,
- wherein the at least one remote frequency conversion processing unit comprises at least one 5G remote processing unit, and a 5G remote processing unit of the at least one 5G remote processing unit comprises:
- a 5G remote downlink processing unit, configured to perform frequency conversion processing on a 5G downlink radio frequency signal and output the processed 5G downlink radio frequency signal to a first switching unit,
- a 5G remote uplink processing unit, configured to restore frequency conversion processing on the 5G uplink radio frequency signal transmitted by the first switching unit and output the restored signal, and
- the first switching unit, configured to switch the uplink and downlink radio frequency signals.
A 5G distributed system, comprising:
- a near-end unit,
- a remote device connected to the near-end unit and comprising:
- at least one remote frequency conversion processing unit, configured to perform frequency conversion processing or restoration frequency conversion processing on a first signal and output the processed first signal, and the first signal including 5G signal;
- and
- at least one remote non-frequency-conversion processing unit, configured to directly output a second signal without being processed by frequency conversion, the second signal including one or more of 2G signal, 3G signal, or 4G signal, and an active antenna unit connected to the remote device and configured to:
- perform restoration frequency conversion processing on the first signal output by the remote device and output the restored signal to an antenna, or
- perform frequency conversion processing on the first signal input from the antenna and output the processed first signal to the remote device, and directly output the second signal received from the antenna or received from the remote device without performing frequency conversion,
- wherein the at least one remote frequency conversion processing unit comprises at least one 5G remote processing unit, and a 5G remote processing unit of the at least one 5G remote processing unit comprises;
- a 5G remote downlink processing unit, configured to perform frequency conversion processing on a 5G downlink radio frequency signal and output the processed 5G downlink radio frequency signal to a first switching unit,
- a 5G remote uplink processing unit, configured to restore frequency conversion processing on the 5G uplink radio frequency signal transmitted by the first switching unit and output the restored signal, and
- the first switching unit, configured to switch the uplink and downlink radio frequency signals.
