Signal Strength
The strength of a signal and resulting range is an outcome of
transmit (output) power and receiver sensitivity
Transmitter Power
• How loud can you yell?
• Higher is better
•Measured in dBm (for example +10dBm)
Receiver Sensitivity
• How well can you hear?
• Lower is better
• Measured in dBm (for example -93dBm)
Why is RF Selectivity Important ?
Poor selectivity require interfering RF systems to be physically moved away
