PWR_STEP and NUM_STEP Definition: PWR_STEP is the access power increment in dB and NUM_STEP is the maximum number of access probes in a probe sequence minus one. The power transmitted on successive probes within a sequence of probes is increased or incremented by a number of dB equal to PWR_STEP. The total number of probes in a probe sequence in which this escalation or stepping of power continues equals NUM_STEP minus one. USE YOUR BROWSER "BACK" BUTTON TO RETURN © 1999 DR. ERNEST SIMO - SPACE2000 PWR_STEP and NUM_STEP Application: USE YOUR BROWSER "BACK" BUTTON TO RETURN © 1999 DR. ERNEST SIMO - SPACE2000 PWR_STEP and NUM_STEP Example: Typically PWR_STEP equals about decimal 3 dB. The access parameters message allocates 3 bits to PWR_STEP, so the step could be as great as 7 dB. The number of probes in a probe sequence is typically around 5. If this is the case, NUM_STEP equals decimal 4 or binary 0100 in the 4-bit format which is allocated to NUM_STEP in the access parameters message. Continuing the example started under the NOM_PWR and INIT_PWR topic, if the initial probe is transmitted at 10 dBm, the next four probes (assuming none of the probes is acknowledged) would be transmitted at powers equal to 13, 16, 19, and 22 dBm.
