Research on Spectrum Sensing Technology for 230MHz Power Wireless Private Network

The power wireless private network system has 40 frequency points in the 230MHz frequency band, if there is no avoidance in the case of interference, it is likely to cause greater interference to the 230MHz data transmission, resulting in repeated retransmissions of the internal terminals of the private network, increasing the time for mutual interference between the systems. Since the power wireless private network mainly considers the interference of transmitters in the frequency band, some typical interference signal sources and their effects are described for various situations. Although affected systems can take advantage of the design to avoid the influence of a given out-of-band signal, an off-band transmitter can still affect transmitter performance within the frequency band. In this paper, aiming at the interference source perception and recognition technology of the power wireless private network in the 230MHz band, a signal spectrum perception process is proposed, which is characterized by a quiet period reserved for the system, in which all the equipment of the system does not emit signals, and the base station and terminal perform spectrum sensing.

With the proposal of ubiquitous electric power internet of things, the power industry’s demand for communication network is more and more intense, and the development of power wireless private network also puts forward higher requirements and more stringent standards for the wireless communication technology involved in it. Therefore, a spectrum sensing technology for 230MHz power wireless private network is proposed in this paper. By taking advantage of the relationship between the two threshold values and the signal-to-noise ratio, adjustment factors are set to achieve different two threshold values corresponding to different signal-to-noise ratios on the premise of avoiding frequent adjustment of threshold values. On the one hand, when the channel condition is good, the distance between the double threshold is reduced also reduce the system computation. On the other hand, when the channel condition is poor, the distance between the double threshold is increased to increase the extraction opportunity of the trust function, so as to improve the detection probability of the system. Finally, experimental results show that the proposed algorithm can effectively improve the communication performance of 230MHz power wireless private network.

Integration of LTE 230 and LTE 1800 in Power Wireless Private Networks

Power wireless private networks (PWPNs) have been highly developed in China in recent years. They provide a basis for the energy Internet of Things, which enables the exchange of energy information between devices. Although the power wireless private network is an imitation of the public cellular network, a number of special challenges remain in power private networks. Due to the lack of general standards for PWPNs at the beginning of deployment, there are now two independent PWPN systems in China: long-term evolution (LTE) 230 and LTE 1800. Each has its own core and access networks with independent hardware. In this paper, we propose a high-level design of multinetwork integration to allow LTE 230 and LTE 1800 to coexist. For core network integration, we propose a protocol controller to select the active protocol according to the user’s mode selection, since both LTE 230 and LTE 1800 evolved from the standard LTE system. For access network integration, we propose a multinetwork integration controller to help the device access the optimal cell. The simulation results show that the integrated system can retain the advantages of these two independent systems in terms of both capacity and coverage.
