Abstract: Integrated power receptacle wireless access point (AP) adapter devices for adapting a power-over-Ethernet (PoE) wall outlet into an access point. Described herein are scalable, dedicated adapters that may be used to adapt an Ethernet wall jack (PoE or non-PoE) into an access point, gigabit switch and PoE power source. These apparatuses may interface with an Ethernet wall jack connected to a network, converting the Ethernet wall jack to an access point and also include a plurality of additional Ethernet connections, including at least one power-over-Ethernet connection.

Abstract: One embodiment of the present invention provides a system for configuring an access point in a wireless network. During operation, the access point discovers one or more existing access points associated with the wireless network. The access point then obtains a set of configuration information from one existing access point, and synchronizes a local timestamp counter to a selected existing access point, thereby allowing the access point to be configured without using a centralized management station.

Abstract: Multi-directional antenna apparatuses, which may include phased array antennas and/or arrays of multiple antennas, and methods for operating these directional antennas. In particular, described herein are apparatuses configured to operate as an access point (AP) for communicating with one or more station devices by assigning a particular directional beam to each access point, and communicating with each station device using the assigned directional beam at least part of the time. Methods and apparatuses configured to optimize the assignment of one or more directional beam and for communicating between different station devices using assigned directional beams are described. Also described are methods of connecting a radio device to an antenna by connecting a USB connector on the radio device to a USB connector on an antenna and identifying the antenna based on a voltage of the ground pin on the antenna's USB connector.

Abstract: A switching system maintains a control-plane operating system and a web server which is in communication with the control-plane operating system. The switching system then sends content by a web page hosted by the web server to a browser on a client device without being solicited by the browser, and allows a user to configure the switching system from the client device via a command line interface presented within the web page on the browser.

Abstract: An interfacing device is configured to process one or more rules, based on sensor data, to perform a predetermined action. During operation, the device can detect a rule-triggering event, and can search a rule repository to obtain a set of rules whose action criteria is satisfied by the rule-triggering event. If the set of rules include a plurality of rules that are simultaneously triggered by the rule-triggered event, the local interfacing device may process the plurality of rules in a user-defined sequence.

Abstract: One embodiment of the present invention provides a cloud-based video monitoring system comprising a camera and a network video recorder (NVR). During operation, the camera stores in a buffer last predetermined temporal segment of a video. The camera also stores a first video file in a local storage corresponding to an event detected by the camera. This first video file is non-overlapping with a second video file corresponding to the event and this second video file is stored in the NVR. The camera generates a third video file by pre-pending last predetermined temporal segment of a video prior to the event to the first video file and sends the third video file to the NVR.

Abstract: Shroud isolation, including choke shroud isolation, apparatuses for wireless antennas for point-to-point or point-to-multipoint transmission/communication of high bandwidth signals, and integrated reflectors including a shroud or choke shroud. A choke shroud systems may include a cylindrical body with an isolation choke boundary at the distal opening to attenuate electromagnetic signals to, from, or within the antenna. The isolation choke boundary region may have ridges that may be tuned to a band of interest. The isolation choke boundary may provide RF isolation when used near other antennas.

Abstract: Apparatuses that operate as both a public address speaker and a wireless access point (AP) for mounting to a ceiling or wall. The compact public address access points described herein may include an AP housing, enclosing a radio (e.g., a 3×3 MIMO radio) and antenna, that is coupled to a speaker assembly including a speaker, a conical acoustic reflector positioned between a front of the speaker and the housing of the AP, and an annular region comprising a concave inner wall facing the conical acoustic reflector. Although the AP is nested atop the front of the speaker, the speaker may produce high-quality sound with accurate voice reproduction without interfering with the operation of the wireless transmission of the AP. Methods of operating and installing these apparatuses are also described.
