The decibel ( dB) is a dimensionless unit, used for quantifying the ratio between two values, such as signal-to-noise ratio. The dBm is also dimensionless, [1] [2] but since it compares to a fixed reference value, the dBm rating is an absolute one. The dBm is not a part of the International System of Units (SI) and therefore is … See more dBm or dBmW (decibel-milliwatts) is a unit of level used to indicate that a power level is expressed in decibels (dB) with reference to one milliwatt (mW). It is used in radio, microwave and fiber-optical communication … See more A power level of 0 dBm corresponds to a power of 1 milliwatt. A 10 dB increase in level is equivalent to a ten-fold increase in power. Therefore, a 20 dB increase in level is equivalent to a 100-fold increase in power. A 3 dB increase in level is approximately … See more • The dBm calculator for impedance matching • Convert dBm to watts See more The signal intensity (power per unit area) can be converted to received signal power by multiplying by the square of the wavelength and … See more • Decibel • Decibel watt See more http://pongsak.ee.engr.tu.ac.th/le426/doc/OptCommC3.pdf WebThe lower the frequency the longer the range. However, the lower the frequency the lower the data rate it can support. As a result, selecting a radio spectrum comes with tradeoffs between range and data rate. Bluetooth® technology uses the 2.4 GHz ISM spectrum band (2400 to 2483.5 MHz), which enables a good balance between range and throughput. flagstar village of coventry
