We saw the document. Comparing solely output power is only part of the equation when determining the overall range of an RF system.
You need to do some research about how power equates to distance. As stated, every 6dB of power doubles the effective range. If you have transmitter that has 100mW output (20dBm), to double the range that transmitter would need to output 400mW (26dBm). The same holds true for receiver sensitivity, with every 6dB of sensitivity increase also doubling the effective range.
High output power burns battery power and can actually damage your body if too high. It's also more prone to reflectivity off nearby object which can cause multi-pathing issues.
The DivBeeâ„¢ RF module that we created is the longest range 2.4GHz device in existence. From RFU to RFU we get up to 7 miles of range with this device, due to the dual diversity antennas with very high signal gain.
