Abstract Considering the issue of slow station access speed leading to a subpar user experience in the current power wireless communication system, this paper proposes an initial networking scheme that enhances the speed of networking by broadcasting current networking frequency information on a designated public frequency point, avoiding sequential attempts at networking on multiple frequency points. Furthermore, the current wireless communication network utilized by the State Grid operates within the public frequency band, rendering it susceptible to co-channel interference, potentially resulting in network unavailability for some stations. Hence, this paper suggests a networking method in which the entered stations sequentially switch frequency points within the beacon/CSMA timeslots to search for potential stations and ultimately transition to a new frequency point suitable for all stations. The experimental results demonstrate that the network access time of the stations unaffected by co-channel interference is only 21.5% compared to the current sequentially detection network access scheme. The stations affected by co-channel interference can still achieve successful network access under the proposed solution, with a remarkable success rate of 100%, thereby effectively enhancing the networking success rate. In summary, the proposed scheme in this paper enhances networking efficiency by addressing both networking speed and success rate. In addition, through calculation and analysis, it is known that the complexity and power consumption associated with networking do not result in significant increments.
