Embodiment Construction

[0026] The principle and spirit of the present invention will be described below with reference to several exemplary embodiments shown in the accompanying drawings. It should be understood that these implementations are described only to enable those skilled in the art to better understand and implement the present invention, but not to limit the scope of the present invention in any way.

[0027] Explanation of terms:

[0028] 5G: the fifth generation of mobile communication

[0029] FREQUENCY: frequency

[0030] AMPLTUDE: Amplitude

[0031] RRU: Radio Remote Unit

[0032] SDPT: RF Single Pole Double Throw Switch

[0033] ATT: digitally controlled attenuator

[0034] AMP: Amplifier amplifier

[0035] LNA: Low Noise Amplifier Low Noise Amplifier

[0036] Please refer to figure 1 , because the indoor coverage system contains multiple transmission signals, such as 2G, 3G, 4G, and the frequency bands of such signals are mostly in the 800-2400MHz, the original coaxial cove...

Abstract

The invention provides a novel 5G indoor coverage system and method based on coaxial feeder lines. The novel 5G indoor coverage system based on the coaxial feeder comprises a base station informationsource and a multi-frequency combiner, and is characterized in that the novel 5G indoor coverage system based on the coaxial feeder is modified based on a coaxial feeder indoor distribution system, and the novel 5G indoor coverage system based on the coaxial feeder further comprises a near-end machine and a 5G power compensation indoor distribution system; the near-end machine is connected to theoutput end of the multi-frequency combiner; and the output end of the near-end machine is connected with the 5G power compensation indoor distribution system.

Description

technical field [0001] The invention relates to the field of 5G technology, in particular to a novel 5G indoor coverage system and method based on a coaxial feeder. Background technique [0002] With the issuance of 5G licenses, the use of indoor traffic has increased significantly, and various operators have begun to build indoor coverage. The 5G standard uses high-frequency signals, which have increased space loss and low penetration capabilities, thus increasing the difficulty of indoor coverage. [0003] The existing indoor coverage schemes are as follows [0004] 1.DAS system [0005] Features: RRU+passive device+feeder+antenna, stable and reliable, lower cost than base station, can support 2G+4G, radio frequency connection, low signal source requirements; but the disadvantages are also obvious: low capacity, difficult to expand, difficult to monitor faults, need The re-laying of optical-electrical hybrid cables or super-category 5 lines makes it difficult to coordina...
