1.3.7.15.2 (25 dBm Bandwidth. The (25 dBm bandwidth of a telemetry transmitting system can be used to determine if the system complies with its RF spectral occupancy requirements. Spurious emissions must be less than (25 dBm to minimize interference levels to …

The requirement for emitted carrier power becomes approximately -38 dBm for the second harmonic and -36 dBm for the 3rd harmonic. The amount of safety factor that should be specified is open to discussion, but it definitely exceeds the European requirement of -30 dBm from 1 to 12.5 GHz. September, 2001 IEEE P802.15-01/437r0

No = N / B (W/Hz) (2.38) where . No = noise power density (watts per hertz) N = thermal noise power (watts) B = bandwidth (hertz) Stated in dBm, No(dBm) = 10 log (N/0.001) – 10 log B (2.39) Combining Equations 2.29 and 2.38 yields. No = KTB / B = KT ( W/ Hz ) (2.41) Stated in dBm, No(dBm) = 10 log (K/0.001) + 10 log T (2.42)

Jul 24, 2003 · The value of 40 dB in the 700 MHz band corresponds to a signal of -92.7 dBm, received by a half-wavelength dipole ((/2) antenna. The thermal noise floor for a 6.25 kHz bandwidth receiver would be in the range of -126 dBm, so there is a margin of approximately 33 dB …
