Abstract
Καθιστά δυνατή την αμφίδρομη επικοινωνία μεταξύ μιας κεφαλής δικτύου και πλήθους χρηστών μέσω του ηλεκτρικού δικτύου και χαρακτηρίζεται από το ότι επιτρέπει τη δημιουργία επικοινωνίας χαμηλής και υψηλής ταχύτητας προκειμένου να παρέχει στους χρήστες πολλαπλές υπηρεσίες υψηλής ποιότητας. Περιλαμβάνει μέσο πραγματοποίησης μερισμού του δικτύου ως προς χρόνο, συχνότητα ή/και πολλαπλή πρόσβαση με ορθογωνική διαίρεση συχνότητας (OFDMA).
