WebAssume that an SNR of 25dB is desired at the receiver. If a 900 MHz transmitter has an EIRP of 100W, and the receiver uses a 0 dB gain antenna and has a 10 dB noise figure, find the percentage of time that the desired SNR is achieved at a distance of 10 km from the transmitter. Assume that the path loss exponent 𝜈 = 4, and 𝑑0= 1 km, Pr ... WebAddition of RSSI and SNR must be considered to evaluate the radio link quality. RSSI is the signal level reception. SNR is the signal noise rate and give indication on the ambiant noise level. Radio link can be considered has GOOD when RSSI > -115dB and SNR > -7dB. Radio link is BAD (range limit) when RSSI <= -120 dB or SNR <= -13dB.
