Helium Amplifier Benchmarking
Posted by GPIO Labs on
Last update on April 23, 2022 We've got some prototypes of our new Helium amplifier in-house and they are currently being tested. Over the past month we have been studying the performance of a Helium Miner with and without the amplifier. The miner is placed in the attic with the stock plastic antenna that has 3 dBi gain. Test Results We looked at the RSSI vs SNR values for one particular hotspot's beacons over time. Here are the results with and without the amplifier The measured gain of the amplifier (in the lab) is about 13 dB...
