  • Patent number: 11856428
    Abstract: Examples described herein relate to an investigator device and a method for determining a condition of an antenna of an access point (AP). At least one investigator device may receive one or more antenna condition test frames transmitted via a plurality of antennas of the AP Further, the at least one investigator device may determine an average received signal strength indicator (RSSI) value corresponding to each of the plurality of antennas based on the one or more antenna condition test frames. A condition of the plurality of antennas of the AP may be determined based on a relative comparison between the average RSSI value corresponding to each of the plurality of antennas of the AP. Moreover, in some examples, the at least one investigator device may send a notification to an administrator of the AP based on the condition of the plurality of antennas.

  • Patent number: 11852743
    Abstract: Systems and methods are provided for learning radio frequency pulses transmitted at various frequencies in a wireless environment, including false radar signals and actual radar. For example, the system can keep a list of radio frequency pulse characteristics detected by access points (APs) but ignored when not declared a radar. The detected radio frequency pulse can be compared with those on the list and may be added to the deny-list if not radar. The AP learns what intervals are normal for the communication environment and if the noise someday looks like a real radar (but it not actually a radar), it will not be classified as radar because it is on the deny-list.

  • Patent number: 11856610
    Abstract: A base station transmits a random access response in response to a random access request (random access preamble) of a user equipment. The random access response includes information about a time when the random access request is transmitted and sequence number information of the random access request (random access preamble). The user equipment checks whether the received random access response is the response of the random access request transmitted by the user equipment, using the information about the time when the random access request is transmitted and the sequence number information included in the received random access response.

  • Publication number: 20230400308
    Abstract: The present disclosure relates to a method for searching for the shortest path having a minimum link between buildings in a rectilinear polygon obstacle environment, which has been implemented to calculate the shortest path having a minimum link, among the shortest paths based on a Manhattan distance from one building to another building, when buildings are given in a rectilinear polygon obstacle environment. According to the present disclosure, in searching for the shortest path having a minimum link between two buildings, a more efficient data structure can be used in terms of an execution time and memory. A building-building minimum link and shortest path search problem can be solved through only the addition of very small operations by using the segment-point minimum link and shortest path search algorithm which can be easily expanded to the building-building minimum link and shortest path search problem.
