  • Patent number: 9596166
    Abstract: The subject matter described herein relates to methods, systems, and computer readable media for testing inter-cell interference coordination capabilities of wireless access nodes. One method for testing inter-cell interference mitigation capabilities of wireless access nodes includes, in a network equipment test device, emulating at least one user equipment (UE) served by a wireless access node under test. The method further includes emulating a wireless access node. The method further includes causing the emulated wireless access node to generate and send an indication of inter-cell interference to the wireless access node under test. The method further includes monitoring the response and evaluating the performance of the wireless access node under test to the indication of inter-cell interference using the network equipment test device.

  • Patent number: 9301170
    Abstract: According to one aspect, the disclosed subject matter describes herein a system that includes a mobile robotic platform for navigating within a coverage area associated with an access point belonging to a communications network under test, wherein the mobile robotic platform includes a client device emulation module configured to emulate multiple client devices that are wirelessly connected to the access point and to send emulated test traffic data to the access point from each of the emulated client devices via a wireless connection. The mobile robotic platform also includes a real client device that includes a client application configured to communicate simulated test traffic data to the access point via an established wireless connection and a performance metrics module configured to determine wireless communication performance metrics associated with the wireless connection between the access point and at least one of the real client device or the emulated client devices.

  • Patent number: 9198064
    Abstract: Methods, systems, and computer readable media for simulating channel conditions are disclosed. According to one method, the method includes storing a plurality of system level metrics associated with various channel conditions. The method also includes receiving data from a device under test (DUT). The method further includes for each of a plurality of user devices or simulated user devices during a test period: identifying, using information about the received data and a precomputed channel type configuration, a first system level metric from the plurality of system level metrics, and providing the first system level metric to the DUT.

  • Patent number: 8929294
    Abstract: Methods, systems, and computer readable media for rapid decoding of wireless communications network uplink data are disclosed. According to one method, the wireless communications network data analyzer receives downlink data generated by a wireless access node. The wireless communications network data analyzer extracts uplink data decode keys from the downlink data. The wireless communications network data analyzer stores the uplink data decode keys. The wireless communications data analyzer captures uplink data and decodes the uplink data using the stored uplink data decode keys.
