Modulation And Bandwidth Combinations; Approved Nxradio Antenna Types - GE MDS ORBIT MCR Technical Manual


FCC Part 15.247 under modular rules per DA00-1407

FCC ID: E5MDS-NX915

ICID: 101D-NX915

Six modulation rate / bandwidth combinations; as seen in Table 3-9:

*1000N occupies 250 kHz less spectrum bandwidth than 1000W which is why it has a "narrower bandwidth", this
comes with a ~2-3 dBm reduction in sensitivity when compared to 1000W kbps. For clear spectrum, use 1000W, for
unknown or busy spectrum it's safer to use the narrow 1000N modem.
