Universidad de Alcalá-OTRI posted this:Cooperative procedure SDN-repair network for faulty paths and network bridgeThe Research Group in Engineering of Telematic Services of the University of Alcalá, presents the following procedure that allows, in a network of transparent bridges equipped with learning functionality of paths of type ARP-Path, in cooperation with the SDN controller, to repair all the paths in use that pass through a certain link when it fails. In this way, when a link or other cause fails, and a path to a bridge terminal has to be repaired, this one informs the controller, sending a Packetln OpenFlow package containing the destination address to be repaired. Its most obvious application is in switches for Software Defined Networks (SDN). The group seeks to reach licensing agreements, commercial or of collaboration agreements with companies from the telecommunications sector, electronic devices and / or computer applications that establish the communications between transparent bridges.
Luxembourg Institute of Science and Technology posted this:TRANSPARENCY OF ACCESS IN PEER-TO-PEER FILESHARING NETWORKSWith the use of peer-to-peer file sharing networks like BitTorrent or Freenet, the distribution of files amongst participants has become fast and easy. In a collaborative environment, this kind of data pool often makes sense, but with the drawback that someone who has provided data to the pool, loses control about who had accessed what file. This transparency of access is often required, e.g. for billing purposes or to fulfil the transparency rule of the new general data protection regulation. There are several options to solve this problem including the use of central systems or logging that involves the source of data. Usually these options introduce single points of failure. The Luxembourg Institute of Science and Technology offers a blockchain based method that is filed as a patent (patent pending) that avoids these single points of failure but still offers the benefits of redundant distributed file storage and still being able to audit selective the access of files.

Data on the production of the BR in the world is hidden. From open sources - the only seller (and, possibly, producer) is an American company SIGMA, selling BR for research. We offer developed strain of BR. A method of producing allows to get BR in large quantities to several kg. The strain is certified and stored in special depositories. BR has unique qualities - the main one is - memory. For BR, it was necessary to find a special strain - producer of BR. Just several countries has the strain (USA, Russia, ..), other data hidden. We also developed such an unique strain.
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.
UATEC - Unidade de Transferência de Tecnologia posted this:Distributed interference cancelation based on outdated channel gain informationA group of researchers from a Portuguese university has developed a technology for distributed communication systems where several pairs of transmitters/receivers communicate simultaneously using the same resources. 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.
University of Vigo posted this:Suppression of Impulsive Noise for 4G cell phonesUVIGO telecom engineers have developed a novel methodology to suppress the impulsive noise present in Long Term Evolution (LTE) cell phone systems. These systems that utilize multiple-input multiple output (MIMO) techniques are already used in fourth generation (4G) cell phones and are expected to undergo further development in a near future. The presence of impulsive noise can be detected comparing the signals received by different antennas, the subsequent application of a enhanced algorithm leads readily to the suppression of the deleterious effect of the impulsive noise on the radio signal. To date, no other methods have been specifically developed for LTE.
University of Vigo posted this:Suppression of Impulsive Noise for Power Line CommunicationsPower Line Communications (PLC) is an emerging field that enables to carry data on a conductor that is also used simultaneously for AC electric power transmission or electric power distribution to consumers. The widespread use of these technologies is however, compromised by the presence of impulsive noise that arises from interferences generated by devices connected to the power line. Therefore removal of impulsive noise is critical to get a high performance of PLC systems. UVIGO researchers have developed a novel methodology to mitigate impulsive noise by monitoring those carriers of the radiofrequency spectrum that are free of transmission in PLC systems. The identification of the noise signals allows its selective removal keeping the quality of the overall PLC signal.
