Abstract: A spectrum access system (SAS) includes a transceiver that receives information indicating a path loss from an interior location to an exterior location in response to a base station being installed at the interior location. The SAS also includes a processor to determine an aggregate interference level for an incumbent proximate the exterior location based on the path loss. An edge router executes instances of a packet core network. The edge router instantiates containers for a connectivity or digital automation enabler and routes customer network traffic without leaving the customer network. A domain proxy receives a request to allocate carriers to a base station and determines whether a frequency separation between the carriers is larger than a bandwidth allocated to an incumbent. The request is rejected if the frequency separation is less than the bandwidth and granted if the frequency separation is greater than or equal to the bandwidth.

Abstract: A first node includes a transceiver configured to detect one or more second nodes that transmit one or more signals on a channel of an unlicensed frequency band. The one or more signals have one or more received signal strengths at the first node that are below an energy detection threshold that indicates the channel is clear for transmission by the first node. The first node also includes a processor configured to modify the energy detection threshold based on the received signal strength.

Abstract: A first node that operates according to a first radio access technology (RAT) provides a first schedule to a second node that operates according to a second RAT. The first schedule requests a first portion of a subsequent time interval for transmission in an unlicensed frequency band. The first node receives one or more second schedules from a second node. The one or more second schedules request one or more second portions of the subsequent time interval for transmission in the unlicensed frequency band. The first node transmits signals in the unlicensed frequency bands during a third portion of the subsequent time interval that is determined based on the at least one second portion.

Abstract: A method of operating a first network element in a wireless communications network to perform WIFI and long term evolution (LTE) communications with a second network element on an unlicensed portion of a radio spectrum, the unlicensed portion being divided into first and second frequency regions, includes performing, at the first network element, WIFI protocol communications over the unlicensed portion, including at least one of transmission to, and reception from, a second network element, of WIFI protocol data using one or more first frequencies of the first frequency region, and performing, at the first network element, LTE protocol communications over the unlicensed portion including at least one of transmission to, and reception from, the second network element, of LTE protocol data using one or more second frequencies of the second frequency region, the WIFI protocol communications and LTE protocol communications being performed by the first network element simultaneously.
