A team of researchers has revealed a new beam-steering antenna that increases the efficiency of data transmission for 'beyond 5G' -- and opens up a range of frequencies for mobile communications that are inaccessible to currently used technologies.The experimental results, presented at the 3rd International Union of Radio Science Atlantic/Asia-Pacific Radio Science Meeting, indicate that the device can provide continuous 'wide-angle' beam steering, allowing it to track a moving mobile phone user in the same way that a…

The beam-steering antenna technology has been developed to increase the efficiency of fixed base station antenna at 5G (mmWave) and 6G, and can also be adapted for vehicle-to-vehicle, vehicle-to-infrastructure, vehicular radar, and satellite communications.

In a step that may help achieve better network connectivity in the near future, scientists have developed a beam-steering antenna that enhances data transmission beyond 5G standards. This will give access to a range of frequencies for mobile communications that were earlier out of reach. With the size of an iPhone, the beam-steering antenna has been developed as a better alternative to the currently used fixed base station antenna. The fixed antennas were found to be inefficient at higher frequencies that limited their…

As you approach the orbit of your new home planet, Gliese 667CC (opens in new tab), you realize you made a terrible, terrible mistake: you didn’t download the latest firmware update for your ships’ communication protocols. While this would be a secondary concern around Earth’s orbit, where the servers holding the installable package reside and radio communications are speedy enough (opens in new tab) to make do, things are different when you’re 22 light-years away from humanity’s cradle. There’s no way for you to…

Amazon's satellite venture, SpaceX's Starlink network and other satellite firms on Wednesday won a combined $278.5 million (roughly Rs. 2120 crore) in contracts from NASA to demonstrate communications in space as the US space agency moves to replace its current satellite network in orbit with privately-built systems.NASA is increasingly looking to rely on private space companies for its operations and wants to stimulate more commercial activity in areas from space communications to sending humans to orbit.Amazon's Project…

Brazilian Communications Minister Fábio Faria said on Friday that the government may schedule a new 5G spectrum auction to sell batches that did not attract interest, mainly in the 26GHz frequency.Brazil telecom regulator Anatel concluded an auction on Friday with Faria saying in a news conference that the sale raised a total of BRL 46.79 billion ($8.44 billion or roughly Rs. 62,600 crores) including future capital expenditure commitments, making it the largest auction of telecom assets to date in Latin America.Telecom…

Air India has curtailed its operations to USA from India in view of deployment of 5G communications by the United States."#FlyAI: Due to deployment of 5G communications in USA, our operations to USA from India stand curtailed/revised with change in aircraft type from January 19, 2022. Update in this regard will be informed shortly," said a tweet from Air India.#FlyAI: Due to deployment of 5G communications in USA, our operations to USA from India stand curtailed/revised with change in aircraft type from 19th January…

The auction of 5G spectrum will be held on schedule and within the stipulated timeline, Minister of Communications Ashwini Vaishnaw said on Monday.His affirmation comes at a time when telecom regulator TRAI's 5G recommendations on spectrum pricing and other nuances, which were widely expected to come by March-end, have spilled over by a few days to early April.Asked if 5G auction will be held as per schedule, Vaishnaw said, "absolutely".He was speaking to reporters on the sidelines of an event - 2nd national conference on…
