Embodiment Construction

[0015] The structure of the present invention will be further described below in conjunction with the accompanying drawings and preferred specific embodiments of the present invention.

[0016] refer to figure 1 and figure 2 Shown in, the working frequency adaptive optimization method of the NB-IOT wireless repeater of the present invention:

[0017] Step 1: When the NB-IOT wireless repeater leaves the factory, input all NB-IOT frequency points planned by the storage operator in its monitoring system in advance.

[0018] Step 2: After the NB-IOT wireless repeater is installed and powered on, its monitoring system will automatically detect the downlink input signal strength of all NB-IOT frequencies that have been input, and compare them. The specific comparison method, for example, can be The downlink input signal strength of all NB-IOT frequency points is compared in turn, and the NB-IOT frequency point with strong downlink input signal strength is selected. After the comp...

Abstract

NB The invention discloses a working frequency point self-adaptive optimization method of an NB-IOT wireless repeater, and relates to the technical field of NB-IOT wireless repeaters. The problem that existing NB-IOT wireless repeater does not have an automatic frequency point selection function and cannot adapt to the technical defect that the frequency point of a donor base station is changed can be solved. After the NB-IOT wireless repeater is installed and powered up, a monitoring system of the IOT wireless repeater firstly automatically and circularly detects all downlink input signal strength of all the NB-IOT frequency points and compares, and the NB-IOT frequency points with the strongest compared signal strength is set as the working frequency point of the NB-IOT wireless repeater; the downlink gain of the equipment is automatically adjusted, so that the downlink output power of the equipment is reasonable, and the uplink gain is adjusted according to the downlink gain to realize coverage of uplink and downlink signals; the manual setting cost is saved, the use is convenient, and the working frequency point changing efficiency is high.

Description

technical field [0001] The invention relates to the technical field of NB-IOT wireless repeater. Background technique [0002] NB-IOT is the abbreviation of Narrow Band Internet of Things (Narrow Band Internet of Things), which is an important branch of the Internet of Everything. Features of NB-IOT: 1. Wide coverage. Compared with traditional GSM, one base station can provide 10 times the area coverage. One NB-IOT base station can cover a range of 10km, and one base station in a small county can cover it. 2. Low power consumption, using AA batteries (No. 5 batteries) can work for ten years without charging. 3. Compared with LTE and GPRS base stations, NB-IoT has increased the gain by 20dB. In theory, it can cover places where signals are difficult to reach, such as underground garages, basements, and underground pipelines. [0003] NB-IOT network has been deployed on a large scale at present, but in the actual application process, a large number of underground parking lot...
