https://devzone.nordicsemi.com/f/nordic-q-a/16755/what-type-of-transmitter-receiver-can-suit-this-purposeHello All, I am looking for a stand alone small transmitter/receiver that can be powered from a watch battery with a range of at least 300m. Is any of the nordic solutions can suit this requirement? Be candid as I am new in the hardware arena. en-USTelligent Community 13Fri, 30 Sep 2016 10:48:03 GMThttps://devzone.nordicsemi.com/thread/64079?ContentTypeID=1Fri, 30 Sep 2016 10:48:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:45d91562-31fd-43a7-b594-b08dd725d7c6FormerMember<p>Using the nRF51822/422 in 250 kbps mode, it should possible to achieve a range of 300 m. However, a range of 300 m is stretching it a little. For long range, it could also be a good idea to add a power amplifier to increase the output power and increase the range.</p> <p>Note: I would recommend you to test it before starting heavy development. If testing the range, it could be a good idea to test the actual use case, it is a big difference between an open field and an area with a lot of obstacles.</p><div style="clear:both;"></div>
