Description
Technical Field
The utility model relates to a 5G technical field, more specifically say, in particular to novel extension of 5G room branch basic station covers end and system.
Background
A fifth generation mobile communication network (hereinafter referred to as a 5G network) is a latest generation cellular mobile communication technology, and is also an extension following 4G (LTE-A, WiMax), 3G (UMTS, LTE), and 2G (gsm) systems. The performance goals of 5G are high data rates, reduced latency, energy savings, reduced cost, increased system capacity, and large-scale device connectivity.
In new network construction, in order to meet the wireless coverage requirement of 5G signals, coverage equipment is generally deployed in a manner of newly building a base station. Since the 5G signal is defined at higher transmit and receive frequencies, coverage of the indoor signal requires a dedicated 5G indoor sub-base station to achieve. Common indoor scenes (including commercial building interiors, hotels, airports and the like) are covered by indoor sub-base stations, and the current mainstream mode is to adopt optical fiber distributed 5G indoor sub-base stations. Each device of the optical fiber distributed base station is an antenna coverage point, so in order to achieve a good coverage effect, massive 5G distributed base stations need to be deployed indoors. The price of the 5G distributed base station is higher than that of the original 4G common antenna by more than 10 times, and the power consumption is also higher, so that the construction investment and the operation cost are greatly improved compared with the 4G indoor distribution scheme for operators and owners, and the scale and the progress of 5G indoor distribution construction are hindered to a great extent.
In order to relieve the pressure, a mode of 5G indoor branch base station + power branch feeder and passive antenna is adopted in the industry to achieve compromise between capacity and coverage cost. Namely, the output of one 5G indoor division base station is connected with a plurality of passive indoor division antennas, thereby realizing signal coverage with larger area. However, the frequency of the 5G wireless signal is high, so the loss of cable transmission is also high, and the output power (generally 200mW) of a general 5G indoor sub-base station cannot be connected with more antennas and longer cables for distributed coverage, and a general scheme can only connect 2-4 pairs of antennas behind the 5G indoor sub-base station. If the number of the rear-end connecting antennas of the 5G indoor sub-base station can be further increased, the extended coverage range of a single 5G indoor sub-base station is increased, the manufacturing cost and the cost of the whole coverage are remarkably reduced, and the 5G indoor sub-base station can be promoted to be better implemented and fall to the ground.
