dBm to Watt Conversion Table
| dBm | Watts |
|---|---|
| 1 | 1.26 mW |
| 2 | 1.58 mW |
| 3 | 2.00 mW |
| 4 | 2.51 mW |
What is Rscp in Wcdma?
RSCP stands for Received Signal code power measured in dbm, It is measured based on received CPICH, which is transmitted continuously by WCDMA base station(NodeB). It is considered as beacon carrier of the WCDMA base station similar to BCCH of the GSM base Station.
How many watts is 43 dBm?
| dBm | Watts | dBm |
|---|---|---|
| 8 | 6 mW | 40 |
| 9 | 8 mW | 41 |
| 10 | 10 mW | 42 |
| 11 | 13 mW | 43 |
How do you convert to Watts?
Obtain Watts from Amps and Volts: The formula is (A)*(V) = (W). For example, if you have a current of 2 A and a voltage of 5 V, the power is 2A * 5V = 10W. This comes from the equation P = I * V.
What is dBm in RF power?
RF power is most commonly expressed and measured in decibels with a milliwatt reference, or dBm. A decibel is a logarithmic unit that is a ratio of the power of the system to some reference. 10 dBm (10 mW) is 10 times more powerful than 0 dBm (1 mW), and 20 dBm (100 mW) is 10 times more powerful than 10 dBm.
What is Rscp in LTE?
RSCP (Received Signal Code Power), the received power on one code measured on the Primary CPICH. The reference point for the RSCP shall be the antenna connector of the UE.
What is Cpich Rscp?
CPICH RSCP (Received Signal Code Power) This is the absolute power level of the CPICH as received by the UE. The reporting range for CPICH RSCP is from -120 dBm to -25 dBm (-5 to 91).
How do you convert dB to dBm?
Decibels are used to represent the ratio of two quantities of power: db = 10 log P1/P0 . In the case of dbm the reference power P0 is 1 milliwatt : dbm = 10 log P1/1mw. Inverting this equation gives the power in terms of the reference power: P1= P010db/10. In the case of dbm the equation is P1= 1mw·10dbm/10.
How many watts is 91 dB?

How to convert watts to milliwatts in dBm?
Watts (W) to decibel-milliwatts (dBm) , power conversion calculator. The power P(dBm) in dBm is equal to 10 times the base 10 logarithm of 1000 times the power P(W) in watts (W) divided by 1 watt (W):
How is the power of RSSI measured in dBm?
RSSI is also a power and its measurement unit is dBm where N represents number of resource block. If RSRP is -60 dBm and the cell is fully loaded (20MHz) and the UE is experiencing 10dBm power from a Neighbour cell operating at same frequency RSSI measured -60 dBm + 30.72 dBm +10 dBm = -19.98 dBm.
How to calculate the power of a DBM?
The power P (dBm) in dBm is equal to 10 times the base 10 logarithm of 1000 times the power P (W) in watts (W) divided by 1 watt (W): P (dBm) = 10 ⋅ log 10( 1000 ⋅ P (W) / 1W) = 10 ⋅ log 10( P (W) / 1W) + 30 1W = 30dBm P (dBm) = 10 ⋅ log 10(1000⋅20W) = 43.0103dBm
Which is the best value for RSRP in dB?
Similar to RSRP , UE reported an integer value to eNodeB and its range is from 0 to 34 (Table 3). 3GPP has provided a table shown below, by using this table the integer value can be translated to a range of RSRP value in dB. The best value of RSRP is about -3 dB and worst value can be -19.5dB.
