The strength of a signal and resulting range is an outcome of
transmit (output) power and receiver sensitivity
• How loud can you yell?
• Higher is better
•Measured in dBm (for example +10dBm)
• How well can you hear?
• Lower is better
• Measured in dBm (for example -93dBm)

Interferer
• More Coordinators needed
• Temporary interference will result in higher
packet loss, more re-transmissions needed
• Less Coordinators needed
• Longer links possible
• Fewer re-transmissions
Why is RF Selectivity Important ?
Poor selectivity require interfering RF systems to be physically moved away
