Described herein are techniques related to a wireless enhanced projector (WEP) that is utilized by one or more devices, such as a mobile phone, a cellular phone, a Smartphone, a personal digital assistant, a tablet computer, and the like. In an implementation, the one or more devices may connect to the WEP through a server device that may be connected and/or integrated with the WEP. In this implementation, at least one of the one or more devices may be configured to be a super-user device (i.e., moderator or administrator device), while the rest of the one or more devices may be regular client devices.

Methods, systems, and apparatus for information exchange are provided. In one aspect, an information exchange method includes establishing a link setup between a centralized unit-control plane (CU-CP) and a centralized unit-user plane (CU-UP) by at least one of sending a first link setup request to the CU-UP using an address of the CU-UP and receiving a first link setup response returned by the CU-UP; or receiving a second link setup request sent by the CU-UP based on an address of the CU-CP and returning a second link setup response to the CU-UP based on the second link setup request. The first and second link setup requests each carry at least one of an identifier of the CU-UP or a name of the CU-UP. The first and second link setup responses each carry at least one of an identifier of the CU-CP or a name of the CU-CP.

A system and method for efficiently establishing secure mobile device communication for location-aware applications. A beacon device broadcasts encrypted packets. Each of the packets includes an indication of a respective time of broadcast. A mobile computing device, such as a smartphone, receives a packet that is broadcast from the beacon device. The mobile computing device determines the packet corresponds to a particular location-aware application and sends the packet to a server. The server determines an expected latency for the received packet based at least in part on crowdsourcing, which includes latencies of other packets sent from the same location. If the server determines the latency of the received packet is not within an expected range, the server considers the packet to be invalid.

Systems, methods, and apparatus embodiments are described herein for controlling policy in integrated small cell and Wi-Fi networks (ISWNs). It is recognized herein that multiple actors within an ISWN may have needs or preferences that conflict with each other, and that the best way of reconciling those conflicting needs is not always to simply give one actor preference over another. As described herein, optimum management decisions may be dynamically based on current network conditions and preferences of multiple actors.

In a position estimation of a terminal using a beacon, the precision is improved by reducing influences of noise due to moving obstacles such as human so that a beacon region can be easily and flexibly constituted. According to a typical embodiment, a portable terminal includes a location determination unit that acquires beacon information including a reception intensity of each of beacon signals received from one or more of the beacon terminals, accumulates history data as beacon detection information, acquires a plurality of pieces of the beacon information accumulated as the beacon detection information and contained within a past predetermined period at every predetermined interval, aggregates the beacon information by scoring, and determines the beacon terminal located most closely based upon scores.

Systems, methods and computer readable memory devices for delivering a presentation are provided. In one example, a method includes establishing a wireless network access point that creates a closed wireless network. An encrypted communication session is established via the closed wireless network with a plurality of client computing devices that each comprise a display. Each of the client computing devices is communicatively coupled to a virtual network server on the host computing device. A resource locator is sent to the client computing devices, with the resource locator including a network location of an audio/video file stored on the host computing device. A request is received for the resource locator from the client computing devices. In response, audio/video data is streamed from the audio/video file to the plurality of client computing devices.

In general, this disclosure is directed to techniques for toggling communication connections based on signal strengths. A first computing device receives an indication of a user input to send data packets to a second computing device. Responsive to receiving the indication, the first computing device determines a signal strength of a first wireless communication connection, comprising one of a cellular network connection or a wireless local area network connection, to the second computing device, and determines whether the signal strength satisfies a threshold signal strength level. Responsive to determining that the signal strength does not satisfy the threshold signal strength level, the first computing device automatically establishes a second wireless communication connection, including a mesh network using a different wireless communication protocol than the first wireless communication connection, to the second computing device, and sends the data packets to the second computing device via the second wireless communication connection.

Disclosed in some examples are devices, methods, systems, and machine readable media that reduce the burden of a master device of a second wireless connection by utilizing the channel map of a first wireless connection. Since both the first and second wireless connections are located at nearly the same location, the “good channels” are very similar for both connections. Therefore a second wireless connection may take advantage of the channel assessment conducted by a first wireless connection in identifying channels by using one or more channels of the first wireless connection for communications in the second wireless connection.

Methods, apparatuses, and embodiments related to a technique for controlling channel usage in a wireless network in a multi-band wireless networking system. In a wireless network with multiple wireless networking devices and one or more client devices, communications between the wireless networking devices occurs via a backhaul channel, and communication between the client(s) and the wireless networking devices occurs via a fronthaul channel. Based on interference characteristics of the wireless channels, a device determines a channel usage plan, and communicates the plan via the backhaul channel to the wireless networking devices of the wireless network.
