  • Patent number: 9918232
    Abstract: A node in a wireless communication system includes a transceiver to receive one or more configuration parameters to configure the node for communication in an unlicensed frequency band. The node also includes a processor to implement a state machine that transitions, based on the one or more configuration parameters, between an enable state in which the node supports wireless connectivity in the unlicensed frequency band, a disable state in which the node does not support wireless connectivity in the unlicensed frequency band, and a flywheel state in which the node supports wireless connectivity in the unlicensed frequency band for a predetermined time interval before transitioning to the disable state.

  • Patent number: 8755805
    Abstract: At least one example embodiment discloses a method of generating a radio frequency (RF) map of a network. The method includes obtaining, by a controller, received signal strengths of at least one user equipment (UE) in a first technology network, determining, by the controller, a back projection of a second technology network based on the received signal strengths, and generating, by the controller, an RF map of the second technology network based on the determining. The back projection represents an attenuation function of a coverage area of the second technology network and the RF map illustrates the attenuation function of the coverage area of second technology network.

  • Publication number: 20140045501
    Abstract: Embodiments of the claimed subject matter provide a manifold network for a wireless communication system. One embodiment of the wireless communication system includes a plurality of base stations and one or more radio network controllers communicatively coupled to the base stations. The base stations can be configured to provide wireless connectivity within a geographic area such that user equipment in the geographic area maintain a substantially continuous call connection with at least two of the plurality of base stations. The radio network controller can be configured to select an active set of base stations from the plurality of base stations for the user equipment. The radio network controller can also be configured to select a configurable number of the plurality of base stations from the active set to maintain the substantially continuous call connection with the user equipment. The configurable number is at least two.

  • Patent number: 7443804
    Abstract: By approximating a packet network, such as the Internet, by an M/M/1 queuing model, the available bandwidth of the network can determined from the variance of the distribution of the sojourn times of packets transmitted through the network. In order to determine the variance of the distribution of sojourn times, and thus the bandwidth of the packet network that is available for transport of packets from an input to an output, a probe train of N packets with known inter-packet intervals is injected from an input on a sending side of the network. At the receiving side of the network, the packet arrival times are measured and the inter-packet intervals of each pair of received packets in the received train are calculated and compared with the known inter-packet interval times of the corresponding input packets.

  • Publication number: 20070180046
    Abstract: A method is provided for controlling data transport in a wireless communications system. The method comprises using a portable diagnostic tool, such as an ultrasound system, to collect information from a patient. The collected information is then transmitted to a remote server of the wireless communications system. The remote server stores the transmitted information and then makes it available for remotely diagnosing the patient.

  • Publication number: 20060063521
    Abstract: A wireless communication system (20) includes a monitoring module (34) that is capable of detecting at least one type of fault scenario in the system. In a disclosed example, sleeping cells (24-30) are detected by determining a deviation between actual cell performance and an expected cell performance. The disclosed examples include automatically determining the expected cell performance and automatically determining any deviation between the actual cell performance and the expected cell performance. Statistical analysis provides an indication whether a determined deviation is indicative of a fault condition.
