Hi,

In general, increased TX output power will give better coverage if all other parameters are kept constant. If the transmitter and receiver are very close to each others, you may not see a large difference in the received signal strength. The range will depend on many factors, including output power, receiver sensitivity, environment, noise, etc. You can have a look at the range estimator from Bluetooth SIG, where you can input your parameters to get an estimate.
If the receiver has an antenna with better receive gain, it may increase its own ability to receive packets from the beacon at a larger area.

One of our FAEs posted some results from his own range testing with different output powers and radio modes in this blog post.

Best regards,
Jørgen
