Is it possible to further reduce the transmission power?

#1

Hi,

I looked at the April Beacon app for Android. It has two options for transmission (tx) power : 0 dBm and -20 dBm. I suppose the transmission power directly affects how far the iBeacon signals can reach. My usage scenario requires differentiating between 2 meters aways on the same floor, and 2 meters away on a different floor, but the estimated distance is unable to differentiate between these two. This happens when the reader (a normal Android smartphone) is upstairs, the beacon is downstairs, but they are directly above/below each other.

I have tried both 0 dBm and -20 dBm, but it seems the signals from the beacon are almost of the same strength. Is there any possibility of further reducing the transmission power, so that without any obstacle, the beacon signals can reach at most 2 meters away? This will basically ensure the signals cannot reach the next floor, which is the behavior I need.

Thanks.

Which model beacon did you buy? EEK? Change TX power to -20 dBm will make the signal weaker.

I bought this :

We have tested the TX power 0dBm and -20dBm. It will affected when the cellphone detect the RSSI.

Do you have an iPhone? You can check with that for better RSSI result.

I have two beacons. One is configured with tx power of 0 dBm, the other -20 dBm. The two graphs were obtained when the beacons were kept at the same place downstairs, while I stood upstairs. The RSSI values seem to be almost indistinguishable. The two graphs were obtained using the Beacon Scanner app for Android. The phone is a Samsung Galaxy Ace 4. Sorry, I do not have an iPhone to test.

Thank you for your valuable information.

We’ve built a new version firmware to fix the issue. Please check your private message for how to upgrade.

Does the AprilBrother library for Android ignore an iBeacon under certain conditions?

I have the same problem, with the same beacon model, can you help me please

Try our new EEK-N beacon instead. It have 9 level TX power options.
