New RF Module, more power!

More Power!

We've just finalized the tests using the new RFM69hW radio, the high-power version of the RF module we initially designed Whisper Node.... and the field results are great, check the results below:

RFM69W vs RFM69hW Range Test
RFM69W vs RFM69hW Range Test

The purple dots represents the RFM69W coverage/range in relation to the Base Station (receiving), while the orange dots represents the RFM69hW.

This new radio offers 100mW (20dBm) TX, compared to 20mW (13dBm) TX of the standard version. It's easy to see the improved range, not only on line-of-sight, with impressive 1.5Km but as well on obstructed paths.

Just be mindful that more TX power doesn't come free, the standard RFM69W module consumes up to 45mA when transmitting, while the high-power version RFM69hW uses up to 130mA.

From Today we've added new reward packs, including the high-power version of the Whisper Node: "High Five pack" and "Five plus Five". Please consider upgrading your reward to a new one. The price will be less than the same packs with the only standard radios, but be quick as this is a limited reward.

Cheers,
Mike M.

      For the RX and sleep modes the power consumption is the same. Also the RX radio sensibility is -121dBm for both versions.

      How does the high power version compare to the low power version for rx and sleep mode?
