  • Patent number: 10374908
    Abstract: Methods and apparatus for controlling a communication network (2) to deliver traffic to and/or from an end node (4) are presented. In an example method, a network node (8) receives information indicating a user-controllable selection at the end node (4) to have at least some of the end node (4)'s traffic delivered with a low priority level that is lower than a high priority level. Accordingly, the network node (8) controls the communication network to deliver at least some of the end node (4)'s traffic with said low priority level and awards one or more tokens accordingly. Furthermore, the network node (8) may receive information indicating a user-controllable selection at the end node (4) to have at least some traffic delivered with the high priority level. The network node (8) may accordingly redeem one or more tokens awarded to the end node (4) and controlling the communication network (2) to deliver at least some of the traffic with said high priority level.

  • Patent number: 10341042
    Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may use a sampling rate that is less than a default sampling rate associated with a wireless carrier. The device may operate in a narrowband portion of a system bandwidth, and the sampling rate may be less than that used by devices monitoring the whole bandwidth. Multiple sampling rates may be used so that a portion of signal processing may be associated with one sampling rate and another portion of the signal processing may be associated with another sampling rate. The size of a cyclic prefix (CP) may be adjusted based on the sampling rate to align subframe timing boundaries for signals of different sampling rates. In some cases, each symbol of a signal may include both a CP and a postfix such that the postfix for each symbol overlaps the prefix of the next symbol.

  • Patent number: 10211867
    Abstract: Various embodiments are described herein that improve the signal reception and transmission capabilities of an access point by coupling an active antenna assembly to the access point. An active antenna assembly includes an antenna and at least one active component, such as a low-noise amplifier or a power amplifier. The active component can be connected to an antenna circuit board rather than the main circuit board of the access point, which is typically retained within an access point housing. By positioning the active component near the antenna, the active antenna assembly prevents degradation of signals received by the antenna. One or more coaxial cables can be used to connect the active component of the active antenna assembly to the main circuit board of the access point.
