Description
Technical Field
The utility model relates to a 5G technical field, more specifically say, in particular to novel 5G micropower amplification system.
Background
With the development of mobile communication network technology and the construction of communication infrastructure, mobile communication network coverage is deeper and deeper, the application requirements of mobile terminals such as mobile phones and the like are also increased explosively, and the user requirements are gradually increased from the initial outdoor application and the basic indoor application to the mobile access requirements of a full scene.
An indoor scene is a typical scene where a user resides, and needs to meet a better network coverage requirement, and due to the fact that shielding of a building is serious, signals of an outdoor base station cannot reach an indoor deep area easily, and the signal coverage effect is poor. In particular, in the 5G network, the frequency of signals is higher than that of 4G, the space transmission attenuation and the wall penetration attenuation of the signals are both larger than those of 4G, and the effect of directly covering the indoor space by an outdoor 5G base station is worse than that of the 4G network.
In order to solve such problems, the conventional solution of 4G indoor coverage is generally followed, as shown in fig. 1, a micro-power repeater is used as a signal amplifier, a donor antenna is placed outdoors for receiving signals of an outdoor base station, the signals are introduced into the room through a radio frequency cable of 10-20 meters, then the micro-power amplifier is connected, and at the output end of the amplifier, indoor signal coverage is performed by using an indoor antenna according to the scene coverage requirement.
Such coverage schemes face new challenges for 5G networks, and 5G systems employ higher modulation degrees to obtain higher access rates, and the high modulation degrees need to have good snr support. After the outdoor signal source is received by the antenna, due to the fact that the signal source is transmitted through the cable with the length of tens of meters, obvious signal attenuation is brought, if the strength of the signal source received by the receiving antenna is not high originally, the amplitude of a useful signal is reduced after the signal is attenuated through the transmission radio frequency cable, the signal to noise ratio is insufficient, the signal to noise ratio is further reduced even if the signal is amplified through the wireless repeater, the signal quality is deteriorated, and the coverage effect of 5G indoor coverage is difficult to achieve. Therefore, a new 5G micropower amplification system is needed.
