摘要： A first base station may be configured as an auxiliary receiver for a data stream sent on an uplink from a source device to a second base station. The second base station may be a base station that is engaged in conventional communications with the source device on uplink and downlink channels using a selected protocol. The first base station may be used to provide extra data redundancy/QoS for a data stream sent from the source device to a destination device through the second base station. The first base station may determine that it has available bandwidth and is able to serve as an auxiliary receiver. The first base station may be asked by the second base station to provide extra bandwidth when certain network conditions occur. The first base station may include a software defined radio (SDR) that may be configured to receive according to the selected protocol.

摘要： Online content is served to participant devices using two or more systems. The content served by each system is not the same. Rather, the content streams coming from each system is a partial or lower-quality version of the original high-quality version of the content stream. A single one of the partial data streams can be used by the participant device to output a lower-quality version of the original content stream to the user. Alternately, the received partial content streams can be combined to output, to the user, a high-quality version of the original content stream.

摘要： The embodiments provide cryptography keys for communicating devices that are based on information known only to the devices. Each device determines the information without communicating key information related to the key with the other. In an implementation, a first device sends a first signal to a second device, the second device loops back the first signal to the first device as a second signal, and the first device generates a first key based on error information from the second signal. Also, the second device sends a third signal to the first device, the first device loops back the third signal to the first device as a fourth signal, and the second device generates a second key based on error information from the fourth signal. The first device and second device then encrypt and decrypt communications between the first device and second device using the first key and second key.

摘要： An initial data center can be selected to host a communication session between multiple participants. This data center can be initially selected based, at least in part, on a first set of effective distances (e.g., representing distances between the initial data center and the first group of participants modified by effective distance factors). For example, the data center closest to the centroid can be selected. The effective distance factor (or weighting) can be based on one or more of the participant's device/driver type, the participant's network type, the participant's connection type, and a participant weighting factor. Then, as the multiple participants on the conference session change or the effective distances change (e.g., based on a change in connectivity), a second data center can be selected to host the communication session.

摘要： One or more data centers are selected to host an online conference. The selection of the data center is based on a set of metrics that are measured from ‘synthetic’ transactions. These synthetic transactions are sent between candidate data centers and the participants in the conference call in order to measure one or more performance metrics (e.g., link quality metrics such as delay, packet loss, etc.) These measured performance metrics are used to determine a centroid that represents the geometric center or ‘center of mass,’ of the link quality between participants and data centers. This ‘link quality centroid’ is used to select a subset of data centers as candidate data centers. The candidate data center with the best average performance metric(s) is selected as the data center to host the conference.

摘要： Auxiliary receivers are used to provide extra data redundancy and/or improved quality of service (QoS) for data transmissions sent on an uplink between a source device and a base station. In the embodiments, an auxiliary receiver may be used to intercept/receive uplink transmissions carrying a data stream from a source device that is transmitting to a base station, where the base station is forwarding the data stream on through a network to a destination device as a first data stream. Upon intercepting/receiving the uplink transmissions, the auxiliary receiver may send the intercepted/received data stream onward through the network to the same destination device as a second data stream that is redundant to the first data stream. The destination device may then process the redundant second data stream in conjunction with the first data stream using techniques that increase QoS associated with the first data stream at the destination device.

摘要： Systems for utilizing bandwidth of a wireless network in an efficient manner are disclosed. Bandwidth may be allocated between different types of devices by dividing a symbol constellation into subsets of points, where each of the subsets may be used for transmitting data from a different device to a base station on single frequency channel. The symbol constellation may be shared on the frequency channel by dynamic or static allocation of the subsets of points to different devices. A first device with high data speed requirements may be allocated a first subset of points of the symbol constellation fix transmitting data to the receiver, while a second device with lower data speed requirements may be allocated a second smaller subset of the symbol constellation for transmitting data to a receiver. The first and second devices may then transmit data to the receiver on the frequency channel.

摘要： The implementations allow increases in data rate provided by the Faster-Than-Nyquist multi-carrier signaling to he balanced against system conditions to maintain transmission error rates on channels within an acceptable range. If conditions such as channel traffic load, inter-system interference, intra-system interference, available transmission power, and/or available bandwidth change, the Faster-Than-Nyquist multi-carrier signaling acceleration factor τ used on system channels may be adjusted based on the changing conditions. If conditions change unfavorably, the acceleration factor τ may be increased to lower the data rate so that the error rate improves on the one or more channels. If conditions change favorably, the acceleration factor τ may be decreased to increase the data rate in the improved channel conditions. During system operation, channel conditions may be monitored, and the acceleration factor on the channels may be adjusted to provided higher or lower data rates according to any changes in the channel conditions.

摘要： Systems, methods, and software are disclosed herein to operate a calendar service to optimize infrastructure support for online meetings scheduled in the calendar service. In an implementation, the calendar service identifies an upcoming meeting from the meetings scheduled in the calendar service. The calendar service further identifies an infrastructure optimization to apply to the upcoming meeting. The calendar service requests an infrastructure management service to apply the infrastructure optimization to a resource during the upcoming meeting.

摘要： A first micro-base station may be configured initiate communications with a plurality of mobile devices, where each mobile device is associated with an access ID stored in the first micro-base station. The access ID may be a MAC ID. The first micro-base station may determine that a handover trigger has occurred. The first micro-base station may handover communications with at least one of the mobile devices to a second micro-base station by sending a list of access IDs to the second micro-base station. The access IDs sent by the first micro-base station may be a subset of the access IDs of mobile devices communicating with the first micro-base station. The second micro-base station receiving the list may then takeover communications with the at least one mobile device using the access IDs in the list. The handover may be transparent to the mobile devices that are handed over.
