Menorca launches 5G connection in the 700MHz band while fiber optics continues not reach in some areas of Ibiza
13/05/2022After the relevant procedures to verify the absence of interference with DTT or other incidents, Movistar has received the green light to turn on 5G in the 700MHz band in Menorca and at this time the municipalities of Es Mercadal and Sant Lluís are already under this coverage. The new 5G in the 700MHz band has better range and better capacity to go through obstacles, thus offering better indoor coverage and universalizing some of the characteristics of 5G communications, such as low latency. The switching on of 5G in the rest of the island will be gradual. And while this is happening in Menorca, in Ibiza, the mayor of Sant Josep, has transferred to Telefónica the need that the operator deploy its optic network to cover all the municipality, because, explains the mayor, there are still areas such as Es Cubells, Cala d'Hort or points in Sant Agustí where the fiber network does not reach. The desire of the Ibiza Town Hall is, furthermore, to turn the capital of the island into one of the first destinations reached by 5G technological leap outside the large cities of the State. “It is a great opportunity for our citizens and the development of new economic sectors. We are also sure that 5G will soon be among the demands of tourists. The 5G availability will allow us to offer an exponential increase in added services to further improve their stay”, explained the Deputy Mayor for Finance and Modernization of Sant Josep, Vicent Roselló.

Video calling apps listen when the microphone is off, according to a study
25/04/2022A group of researchers from the University of Wisconsin-Madison (United States) has determined that video conferencing applications can continue accessing audio data even if the user has disabled the microphone. To demonstrate this, they have studied the most popular video conferencing applications and have analyzed the behavior of the mute button until they has determined that all the applications that they has tested whether the microphone was open or closed, occasionally collected raw data and delivered it to the servers of their services. In their research they have worked with binary analysis tools to see how the audio was transferred from the application to the audio drivers of the computers and then to the network. They aslo have created, through machine learning models ( 'machine learning'), a classifier of daily activities that, with 82% accuracy, has determined which activities users were doing while their microphones were, theoretically, silenced. In relation to this, the authors of this work recall that beyond muting the microphone, you can turn off the microphone of a device through the settings menu, a safer option to limit access to confidential information and sensitive data. All the conclusions of this study will be known next July in the Privacy Improvement Technologies Symposium.
