SINR/SNR – The signal-to-noise ratio of the given signal. typical range is around -44dbm (good) to -140dbm(bad).
What is the ideal SINR?
Generally, a signal with an SNR value of 20 dB or more is recommended for data networks where as an SNR value of 25 dB or more is recommended for networks that use voice applications.
What is 4G SINR?
Signal to Interference plus Noise Ratio (SINR)
SINR is a measurement of the interfering noise against the actual signal being received by the 4G LTE modem. In the case of the SINR, it should be a positive number and the larger the number is from zero the better your SINR is.
Why is SINR low?
Low SINR is caused by long distance between transmitter and receiver, the communication channel being in fade, or interference from adjacent wireless transmissions over the same frequency spectrum. Furthermore, there is a growing interest in low SINR operation for improving the throughput in wireless networks [3].
What is SINR?
SINR (Signal to Interference & Noise Ratio) measures signal quality: the strength of the wanted signal compared to the unwanted interference and noise.
Is negative SINR good?
Negative SNR (Signal to Noise Ratio) when expressed in dB just means that you have more noise than signal. For simple communications systems this means you have no useful signal and so can not make reliable estimates of the transmitted information.
