NEC has introduced a groundbreaking radio-over-fibre system featuring 1-bit fibre transmission, designed to create affordable, compact distributed antenna units (DAUs). This innovative technology transmits high-frequency analogue signals using a cost-effective electrical-to-optical converter, commonly used in digital communications.
In a groundbreaking move, Hong Kong has allocated mmWave frequencies to its four mobile network operators without charging for the spectrum. The Office of the Communications Authority (OFCA) announced on Tuesday that it will distribute 1.2 GHz of spectrum in the 26 GHz and 28 GHz bands in the third quarter of this year, following applications from the telcos earlier this year.
The FCC’s recent proposal for shared access of the 42 GHz band could revolutionize the telecom industry by introducing new service providers and business models. With mixed reactions, the proposed sharing mechanism aims to prevent interference and encourage competition, potentially attracting companies like Amazon to the mmWave spectrum.
