Frequency resource planning method for power wireless private network system

Abstract

The invention relates to a frequency resource planning method for a power wireless private network system. The frequency resource planning method comprises the steps: estimation of the number of different service terminals in an area, frequency resource interference statistics, calculation of available frequency resources according to service classification, calculation of different service frequency requirements and matching of different service frequency resources. According to the invention, frequency use and interference conditions in a 230MHz frequency spectrum range are obtained throughthe frequency spectrum sensing technology, thereby effectively evaluating the interference level of each frequency sub-band. When frequency points are found to be used and interference is large, avoiding needs to be carried out in time. A sub-band without interference or with smaller interference is dynamically selected, the communication quality is optimized, the interference with different systems is reduced, an exclusive frequency pool is configured for each type of service, the optimal configuration matched with resource management and service guarantee is achieved, and the frequency resource planning and accurate control of the power wireless private network are achieved, so as to ensure the stable operation of the system.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a frequency resource planning method for a power wireless private network system. Background technique [0002] The power wireless private network communicates based on the 230MHz dedicated frequency band allocated by the State Radio Regulatory Commission. Its frequency points are discretely distributed in a total of 12MHz bandwidth from 223MHz to 235MHz, and each frequency point has a bandwidth of 25KHz. In addition, there are 360 ​​frequency points within this frequency range (A total of 9MHz bandwidth) is approved by the radio management offices of various cities and needs to be applied for use. With the application and promotion of electric power wireless private network, 230MHz electric power wireless private network, 230MHz data transmission radio station and other high-power radio stations may coexist in the spectrum of 230MHz frequency band at the same time...

AI Technical Summary

Problems solved by technology

However, this method performs resource matching according to a fixed pattern and does not support real-time dynamic frequency allocation

Although the main business positions such as power distribution automation and power consumption information collection in the actual power business are relatively fixed, there are still frequency occupation and interference. Therefore, it is necessary to improve the existing technology to meet the requirements of the power wireless private network System Operational Requirements
