1. An open radio access network distributed unit (O-DU) comprising an electronic module that performs an FS-8 Radio Access Technology (RAT) functionality selected from the group consisting of:
frequency hopping;
downlink (DL) carrier aggregation;
uplink (UL) channelization;
power control; and
fast automatic gain control (AGC);
wherein the O-DU is adapted to provide,
a joint UL component carrier channelizer;
frequency hopping for 2G FS-8 RAT;
power control and AGC for FS-8 RAT;
sample rate conversation over an O-RAN compliant fronthaul carried IQ.
