Why rx level is negative value

Thanks Petre!! Thanks for pointing out the mistake. Corrected it. Sir , I have a doubt. Isn't it wrong because if you mean that the RxLevel is the strenght of the signal received from the BTS then the Pt should be the one from the source because it's the one that transmit and then the RxLevel will show properly its degradation in power?

Hi I didn't get what your exact question is? Can you email me at satyashravans gmail. You want to sell old mobile online at www. Saturday, October 25, Rx Level - Why is it negative?? Before i tell you why Rx level is negative, you must know about 'dBm'. The Tx level is the power in decibels per milliwatt dBm at which a modem transmits its signal. The Rx level is the power in dBm of the received signal. The server modems normally transmit at dBm by default.

Ideally, the Rx level should be in the range of to dBm. If the Rx level is too high, you may see signal distortion or the receiver's Digital Signal Processor DSP being overdriven, and erratic connections are possible. In some modulation standards, such as V.

If this behavior is widespread, try configuring the transmitter to transmit at a lower level. Modems that use other modulation standards such as K56 Flex may not be able to do this, resulting in problems. Therefore, an effective Rx level is a function of the peer's initial Tx level, the negotiated dBm reduction if any , and the attenuation in the voice circuit.

The voice circuit attenuation is, in turn, a function of link attenuation and of analog or digital pads, which are telephone company circuitry designed to insert attenuation into the voice circuits. If you need to reduce or increase your Tx level, this is attainable with the following modems and modulation standards:. Microcom through T51??? NextPort through S39 or S59??? Why RX is it negative value?? It is measured power referenced to one milliwatt mW. Rx-Level Rx-Level is define as The power level corresponding to the average received signal level of the downlink as measured by the mobile station.

The range of Rx-level is between to Wireless signal strength is measured in dBm decibel milliwatts and is, somewhat confusingly, expressed only as negative values. Anything down to this level can be considered excellent signal strength. Good, reliable signal strength. Tx is transmit such as to Bluetooth speakers from a audio device.

Rx is receive from a device audio player of any sort to Bluetooth headphones except AirPods.
