Radios: 5G and Beyond
The 5G is the next standard of wireless communication that will be able to satisfy the increasing demand of higher speeds, traffic and users. The basic requirements includes :
New carriers and bands
Full duplex (same frequency for RX and TX at the same time)
Massive MIMO (multiple RX-TX to exploit diverity and spatial multiplexing
ULP Low data rate modes (Bluetooth low energy (BLE) and Narrowband IoT)
In particolar we can distingueshed two main group of research:
Sub-6GHz Radios
Sub-6GHz Radios
Sub-6GHz radios works to frequency up to 6GHz, it is characterized by a lower speed than mmWave radios but it can reach higher distances.
Millimeter-Wave Radios
Millimeter-Wave Radios
The mm-Wave technology uses frequencies between 30 to 300GHz providing high speed communications for short distances.
