An electronic device able to communicate using both a long-range and a short-range wireless communication technology. A transceiver of the electronic device switches its operation mode based on a power saving mode of the long-range wireless communication technology. In particular, the electronic device switches between a short-range mode and a long-range mode based on the power saving mode of the long-range communication technology.

Dual-mode electronic device

A system and method for enabling secure device-to-device (D2D) communication between a plurality of user devices. The method includes providing public and private keys for each of the user devices, the private key arranged to decrypt data encrypted by the corresponding public key. A sender user device creates a digital signature using its private key. The sender double-encrypts a transmission using both the public keys of a recipient user device and a first relay user device. The transmission is transmitted from the sender to the recipient through a plurality of relay user devices. Each relay user device receives the transmission, decrypts a first layer of encryption with its private key, encrypts the transmission with the public key of a subsequent user device; and forwards the data transmission to the subsequent user device. The recipient authenticates the digital signature of the sender using the public key of the sender.

System and method for end-to-end secure communication in device-to-device communication networks

An outdoor lighting network (OLN) is disclosed as a supplementary or contingency communications infrastructure for smart city systems. The OLN may integrate light points within the network as receivers which are switched from a standard OLN communication protocol to a D2D based protocol upon disruption of a primary smart city systems communications network, wherein each communication protocol includes a respective message prioritization method. Aspects of the disclosure additionally includes methods and apparatus for implementing an outdoor lighting network which can act, in cases of primary communication failure, as a D2D network in order to pass messages from smart city system field devices, through the converted D2D OLN network and to a smart city system central manager for proper handling and distribution of the smart city system field device communications.

Outdoor lighting network as a contingency connectivity infrastructure

A method and corresponding system is disclosed for use in a Networked Lighting Control System whereby communication costs (e.g. costs associated with LTE technologies), variable electric rates and traffic models are analyzed to maximize cost savings. In one example, the system consists of receiving cellular usage rates, electric usage rates, and generated traffic models or statistics to manage transmission and broadcast of usage rates to lighting poles. An apparatus associated with the lighting pole can then use this information to determine frequency of sending lighting commands to nearby poles.

Lighting system optimized for cost reduction

The invention provides a light management information system for an outdoor lighting network system, having a plurality of outdoor light units each including at least one sensor type, where each of the light units communicates with at least one other light unit, at least one user input/output device in communication with at one or more of said outdoor light units, a central management system in communication with light units, said central management system sends control commands and/or information to one or more of said outdoor light units, in response to received outdoor light unit status/sensor information from one or more of said outdoor light units or received user information requests from said user input/output device, a resource server in communication with said central management system, wherein the central management system uses the light unit status/sensor information and resources from the resource server to provide information to the user input/output device and/or reconfigure one or more of the lights units.

Methods and apparatus for information management and control of outdoor lighting networks

Inventive methods and apparatus for management of outdoor lighting networks. In particular, methods and apparatus are provided that enable the operation and management of outdoor lighting infrastructure leveraging an ITS infrastructure and connected devices, as well provided parking and payment services to users.

System and method for outdoor lighting operation and management using its protocols and connectivity infrastructure

A method and system to extend the coverage of Outdoor Lighting Networks (OLNs) through the use of authorized mobile devices travelling around to establish a virtual connectivity link (i. e., storing data and, when in reach, using short-range wireless communication protocols) between isolated light points (or groups of light points) and connected light points so that lighting commands and data can be exchanged between the two sets of lighting points is disclosed.

Extending coverage in an outdoor lighting system by using a mobile device and short-range wireless communications

A system and method for providing directional information to a user using existing infrastructure elements () is disclosed. The method comprising determining a route of infrastructure elements () between a current location and a remote location, wherein the current location is associated a first element in the route and the last element in the route being closest to the remote location, wherein each of the elements in the route are identified by at least one of: a physical identification and a data identification, and providing a visual indication, progressively, to each of the infrastructure elements in the route at a predetermined time and for a determined period, wherein the progressive display of the visual indication provides for direction control information.

Streetwise navigation system using infrastructure elements

The present invention proposes an apparatus and a method for selecting a transport control mechanism to be used between a first device () and a second device (). Firstly, a first unit () obtains first information indicating the transport control mechanism supported by the first device () and second information indicating the transport control mechanism supported by second device (); then, a second unit () selects the transport control mechanism to be used between the first device () and the second device () on the basis of the first and second information and a preset rule. With the apparatuses and methods provided in the present invention, the problem of how to select the transport control mechanism to be used between the media server and the media client is well solved. Furthermore, by applying the defined messages and the interaction process in IGRS protocols, there is no need for additional messages nor for an additional interaction process.

Apparatuses and methods for selecting a transport control mechanism

Inventive methods and apparatus for management of outdoor lighting networks (A-C,A-C). For example, in some embodiments methods and apparatus are provided that enable communication between a central management system () and a plurality of unique outdoor lighting networks (A-C,A-C).

Methods and apparatus for management of outdoor lighting networks

The present invention proposes a method of managing a network comprising a set of devices for transmitting a traffic stream using network resources. Each device of the set of devices is individually associated with an expiration time. The expiration time defines a maximum interval of sending a message by a given device among the set of devices for indicating that the given device is connected with the network. The method comprises a step of determining, based on the expiration times of said set of devices, a transmission lease time defining duration of using said network resources.
