Abstract: In a base station having a Massive Multiple Input Multiple Output (M-MIMO) antenna array, the availability of the M-MIMO antenna array is exploited to manage the interference caused by the base station to neighboring cells. In one embodiment, the large number of antenna elements of the M-MIMO antenna array are used to create precise transmit and/or receive spatial nulls at specific User Equipments (UEs) being served by a neighboring cell and/or in select areas of the neighboring cell. Depending on whether the spatial null is partial or full, transmissions by the base station may have reduced or even zero receive power within the neighboring cell.

Abstract: A device is disclosed that is capable of determining its location using high-power with high accuracy, and using low-power with lower accuracy. By coordinating usage between the high power method and the low power, overall power consumption of the device can be significantly reduced without a significant reduction in accuracy. Such high accuracy may be achieved through the use of a GNSS unit, such a GPS receiver. In addition, the low-power alternative may be achieved using an accelerometer, together with software, hardware or firmware for extrapolating a speed based on the force measurements by the accelerometer. In this manner, the GPS receiver can be operated for only a fraction of overall use, primarily to provide adjustment data necessary to calibrate usage of the accelerometer.

Abstract: The subject system allows network devices utilizing any number of networking technologies (including to-be-developed technologies) to access a common abstraction layer and/or the network operations facilitated by a common abstraction layer. The subject system allows a device that is added to a network to communicate whether existing devices on the network should retrieve communication protocol information for facilitating communication with the added device from a remote server. For example, the devices may locally store communication protocol information for certain network technologies, e.g. legacy network technologies, while information corresponding to other network technologies may not be locally stored. The added device may provide a resource locator to the existing devices for accessing the communication protocol information from the remote server.

Abstract: An apparatus for operating a low data-rate (LDR) link and legacy switch at a high data-rate (HDR) includes a first block and a second block. The first block receives input signals from the legacy switch and generates identical output signals. The second block receives the identical output signals and generates an HDR signal for communication over the LDR link coupled to an access point. Further, a media access control (MAC) interface communicates data at a first data rate with an Ethernet PHY block including a first-in-first-out (FIFO) module and a buffer. The FIFO receives data from the MAC interface at the first data rate and transmits data at a second data rate. The buffer receives data from the Ethernet port at the second data rate and transmits the received data at the first data rate in response to detection of an end of packet.
