University of Huelva posted this:Power supply system controlled from internet for devices connected to a lanNowadays there are devices that allow the control of devices connected to a network from the own network. The classical method to access them from a different network is the redirection of the corresponding TCP or UDP connections to local networks from the border router. The redirection requires a high level of expertise in communications to be performed. Another strategy that is often used is the creation of VPN (virtual private network). This technique allows the control of access but does not allow connections to be discriminated or the management of power supply. The proposed system allows you to control the person and the moment to access as well as the free access. The modification of these constrains can be performed in the course of an access session. In addition, the system allows the control of power supply of the device you want access to. The interface is very friendly and does not require continuous changes in the configuration of the router. The system has a local database access control and validation can be delegated to other servers using protocol validation like LDAP, IMAP, POP3, etc.

The main applications of this Ethernet switch technology are networks of data centers and computer networks in general, audio-video bridges and other types of transparent Ethernet bridges. The group is looking for companies in the telecommunications sector with the aim of reaching technical collaboration agreements, commercial agreements or patent licenses.
University of Huelva posted this:New device and system for the recovery of communication equipmentThe present device is focused on the automatic recovery of operating systems for routers and switches, which is one of the fundamental claims on this invention since there are no current devices in the state-of-the-art for such purposes. Another particularity that distinguishes to the present invention is that it is not only software or hardware in contrast to other approaches, but of a complete hardware/software device (i.e, both capabilities are combined). Another of the most significant singularities is its portability, since the invention is based on a reduced size device (non rackable) and made up of autonomous battery. This allows to carry out any function with total freedom to move. Besides the comfort, it contributes a great improvement in working time, since operating with distant devices implies an additional time in turning off, turning on again, and enabling the necessary services to start the recovery procedure. As additional feature, the invention looks for the universality and independence from manufacturers or device model. Besides this purpose, another differentiated function is the capability to store the firmware of the communication devices to be recovered (i.e., the image of the operating system) through an internal physical storage unit of great capacity.

On the other hand, the innovation allows reusing the RJ plug as many times as required until properly assembling the copper pairs. Furthermore, the connector incorporates an identification by color codes for wiring according to the ANSI/TIA-968-A-2002 standard, which is ideal for people with limited dexterity on IT.
Universidad de Alcalá-OTRI posted this:Novel Synchronization Process for Multi-carrier or Single-carrier CommunicationsThe research group “Communications, Multirate Systems, and Biomedical Engineering” of the University of Alcala presents a novel synchronization procedure for multicarrier or single carrier systems for narrowband and broadband communications. This procedure allows a precise estimation of the symbol timing offset (STO), and a coarse estimation of carrier frequency offset (CFO). The procedure is based on the inclusion of symmetric extensions in the transmitted symbols for the synchronization, which makes it useful not only for communications systems based on the discrete Fourier transform, but also for transceivers based on the discrete cosine transform (DCT). Among its main applications are communications through single-mode optical fiber, powerline communications, wireless and wireline systems, and in general, all the techniques that use multicarrier and single carrier modulations. The group seeks companies from the telecommunications sector to sign technical cooperation agreements, commercial agreement with technical assistance and patent licensing agreements.

The invention aims to increase the throughput of current cellular communication systems. The advantages of this technology in relation to existing solutions are: 1) the throughput is enhanced and proportional to the square root of the number of transmitter/receiver pairs. 2) the interference is canceled using only outdated channel gain information and the interference removal procedure is distributed. The university is looking for companies on the wireless communications arena interested in improving the capacity of their communication systems.

PhotonDelta posted this:Method and arrangement for microwave signals transmission through a multimode fiberThe invention provides a solution for the direct transportation of analog electrical signals, in particular radio signals, via a multi-mode optical fiber, so that it will be possible to transmit the transferred radio signal without any further signal processing at the base stations. Especially if a large number of base stations are used, as in the case of wireless networks as explained in the foregoing, it will be advantageous to keep the base stations as simple as possible. Not only does this provide a direct financial benefit as regards the cost of the base station itself, but it also enables a considerable saving on maintenance and repair costs of the network.
