A donor communication station transmits a unicast transmission comprising a plurality of device data sets where each device data set directed to each of a plurality of user equipment (UE) devices. A relay node receives the unicast transmission and retransmits the data sets in a broadcast transmission over a broadcast communication channel to the plurality of UE devices. In one example, the donor communication station encodes data for multiple user equipment (UE) devices by applying broadcast encoding to the data for each device before applying outer encoding to the data. The dual encoded data is transmitted to the relay node over a dedicated channel. The relay node applies outer decoding to the dual encoded data to retrieve the broadcast encoded data. The relay node then transmits the broadcast encoded device data in a broadcast transmission without outer encoding.

The described technology is generally directed towards proactive content placement for low latency mobile access. Digital content requested by a mobile device can be sent to network nodes proactively, so that the network nodes have the digital content before it is requested by the mobile device. Mobile device travel predictions can be made to predict future locations of the mobile device. The future locations can be used to determine network nodes for proactive digital content delivery. The digital content for delivery to a network node can also be predicted based on current digital content in use at the mobile device and estimated arrival times of the mobile device into service areas of next network nodes.

A cellular system includes cell sites, each having multiple cells. Each cell identifies a radio coverage area and includes communication equipment. A method for managing the cellular system includes determining, among the cell sites, a candidate cell site to be at least partially deactivated. The candidate cell includes at least one associated cell with a load factor below a threshold. Replacement cells are selected from other cell sites, where the replacement cells are adjacent to the candidate cell. A target geographical area enclosing the area of the candidate cell and that of the replacement cells is identified, and a transmission parameter for the target geographical area is determined. Communication equipment associated with the replacement cells is selected and configured based on the transmission parameter. Then the candidate cell monitors the transmission parameter in the target geographic area, and at least partially deactivates based on the monitoring.

An arrangement suitable for a mobile local wireless network includes: a gateway to facilitate a local short-range wireless network, to receive at least sensor measurement data via the short-range wireless network, and to be connected to an in-situ computing device; a computing device connected to the gateway, having a unit to obtain sensor measurement data via the gateway from sensor nodes; a sensor node transmitting measurement data via long-range wireless networks, and transmitting measurement data and receiving beacon signals via short-range communication. The gateway sends beacon signals. The sensor node receives a beacon signal and utilizes only the short-range wireless network for sending the measurement data, terminating transmission of data over long-range wireless networks for a period of time, in accordance with commands received from the gateway or as long as a beacon signal is detected at the sensor nodes. Corresponding gateway, method and computer-program product are also disclosed.

A wireless connection system executes wireless connection between an information terminal of a user and a display device installed in environment. In a case where an information terminal existing in the vicinity thereof is detected, the display device displays device ID information related to authentication for wireless connection with the detected information terminal (or an image obtained by coding it) on a display screen. The information terminal confirms whether the device ID information read from the display screen match device ID information of an own device or not, and establishes wireless connection using an authentication ID for wireless connection with the display device after matching is confirmed. The display device establishes wireless connection with the information terminal using an authentication ID.

A path selection apparatus for selecting a path when storing sensor reports from lower nodes in a packet and transmitting the packet to an upper node in a sensor tree including a plurality of nodes includes a node movement unit that selects a first node holding a child node under the first node in the sensor tree, and moves a second node under the subtree with the first node as a vertex to a position under a third node not belonging to the subtree in the sensor tree when a movement of the second node to the position under the third node decreases a total number of packets to be transmitted and received in the sensor tree.

The train detection system comprises a wireless communication network further comprising train detection modules attached to catenary poles at the entrance and exit of the railyard. Each train detection module is equipped with a plurality of diverse sensors configured to detect trains and other on-track vehicles. The diverse sensors are simultaneously active and work together for detecting an approaching or leaving train. The train detection modules generate train alerts which are transmitted wirelessly over the wireless communication network. Each of the railyard workers wears a personal alert device capable of wirelessly connecting with the train detection modules and receiving the train alerts over the said wireless communication network. The train alert modules are capable of transmitting alerts wirelessly to personal alert devices and other train alert modules. Train alert modules are capable of generating audio visual warnings for any personnel which may not be equipped with personal alert module.

Systems and methods for analyzing available networks and transferring data via a two-way radio transmission are described herein. An example method may commence with collecting, by a data collection device, asset data. The method may continue with preprocessing, by the data collection device, the asset data for transmission. The method may further include dynamically analyzing, by the data collection device, networks available for transmission of the asset data determining a mode for the transmission of the asset data. The method may further include transmitting, by at least one of the data collection device and a two-way radio device communicatively coupled to the data collection device, the asset data to a data server. The asset data may be transmitted based on the mode for the transmission via at least one communication channel and at least one intermediate device.
