A technology that can revolutionize the "world" of wireless networks, thanks to the use of ultra-high frequencies, is expected to be presented at Intel's Mobile World Congress.
According to a post by MIT Technology Review, the company has built a prototype antenna that can be mounted on stations the size of a milk carton. What the technology in question – "millimeter wave modular antenna array" – actually does is incorporate high-speed "fifth generation" (5G) capabilities, such as those demonstrated last year by researchers at Samsung and New York University, in a small-sized device. The central idea is to cover cities with such device-stations (one by one with two building blocks) that will be able to handle large volumes of data in a small range. Each such station will be able to send and receive data at speeds of more than one gigabit per second, within a few hundred meters, while the current standard, 4G LTE, "moves" around 75 megabits per second.
Intel and Samsung technologies are expected to use frequencies of 28 and 38 gigahertz or higher for portable device communications purposes. These frequencies, known as the "millimeter wave", can carry much more data than those used in today's mobile networks, but are easily blocked by interfering environmental objects, so they were impractical for use on portable devices.
To address this problem, the processors προβαίνουν σε δυναμικές αλλαγές πάνω στη μετάδοση και τον διαμοιρασμό του signalτος, ελέγχοντας την κατεύθυνση προς την οποία αποστέλλεται το σήμα από κάθε κεραία, κάνοντας συνεχείς αλλαγές ανάλογα με τις μεταβαλλόμενες συνθήκες του περιβάλλοντος. Πάνω στην ανάπτυξη τέτοιων συστημάτων εργάζονται πολλές ερευνητικές ομάδες, ωστόσο η Intel υποστηρίζει ότι η προσέγγισή της είναι η πλέον αποτελεσματική.«Μπορούμε να αυξήσουμε τον αριθμό των κεραιών όσο θεωρούμε ότι είναι πρακτικό για να αυξήσουμε την ευαισθησία μετάδοσης και λήψηs. The barriers are regulatory in nature, not technological," says Ali Sandri, director of the relevant department at Intel, in the MIT Technology Review.
