Pygate RX Sensitivity

[d.alvrzx]

Hello all!

I was wondering, how does the sensitivity of the Pygate compare to, say, the Laird RG1XX Gateways? The Laird modules have a stated sensitivity of -127 dBm (assuming Bandwidth = 125 kHz, Spreading Factor = 7, DR0), but I couldn't any similar parameter listed in the Pygate datasheet.

Any ideas, @Gijs ? Or possibly somebody else :)

Best,

Dan

Hi,
On the Pygate, we feature a Semtech SX1308 concentrator with SX1257 frontends. The combination has a theoretical sensitivity of -139dBm. I do not believe we measured the actual performance in this regard.

Adding the SNR_min and Ptx, gives an even higher link budget :)

@Gijs Wow. -139 dBm seems very sensitive. I will look into it, do some tests with both GW and see how they compare. Will post back when that is done.

IMHO this has not anything to do with the actual physics. It's just calculated numbers.
