摘要： A software application executing on a server and communicating with an agent in a wireless access point predicts a type of a computing device wirelessly connected via a radio frequency link to the wireless access point. The application receives an indication of a model of the computing device from the wireless access point, and further receives one or more characteristics of the computing device from the wireless access point. The application then predicts the type of the computing device associated with the one or more of the indication of the model, and characteristics, of the computing device.

摘要： A passive optical network system includes an optical line terminator (OLT) configured to detect signal strength and a phase of a burst-mode uplink signal from each of optical network units (ONUs) to control the ONUs so as to equalize signal strengths of signals received from the ONUs and configured to control the ONUs so as to adjust a phase of each of the signals received from the ONUs, and the ONUs are each configured to control signal strength and phase of an burst-mode uplink signal and transmit a resultant burst-mode uplink signal under control of the OLT.

摘要： Systems and methods for controlling a wireless network receive data from wireless access points within a wireless network and use the data in a model of the wireless network to identify allowable transitions between states defined by the model. Parameters for the wireless access points are adjusted to initiate transitions between the states and, based on the transitions, the model is updated.

摘要： An optical transceiver of the present invention includes a coexistence element therein. An optical signal according to a first standard and an optical signal according to a second standard are transmitted and received through an optical cable accommodated in a first receptacle of the optical transceiver, and in the coexistence element, the optical signal according to the first standard and the optical signal according to the second standard are divided/combined. Among the divided upstream optical signals, the optical signal according to the first standard is photoelectrically converted in the optical transceiver, and the optical signal according to the second standard is transmitted to the outside through an optical cable accommodated in a second receptacle.
