Introduction

The physical layer defined in this part of GB/T 19882 is based on IEEE802.15.4g standard and supports 470MHz ~ 510MHz band (MR-FSK) physical layer, multi-rate multi-area orthogonal frequency division multiplexing (MR- OFDM) physical layer and a multi-rate multi-region offset quadrature phase shift keying (MR-O-QPSK) physical layer. Among them, MR-OFDM physical layer Support mode 3 and mode 4. In addition, this part also includes DL/T 698.44 standard, as the fourth choice of physical layer rules Fan. National Committee has no provisions 470MHz ~ 510MHz frequency band can be used as civilian radio metering frequency band.
