RF Coverage Performance

 RF Fundamentals Still Apply to Digital

– Mean C/(I+N) in fading must still achieve minimum level

 But Digital Introduces New Elements

– Ability of forward error correction to deal with error events

– Especially error events caused by delay spread

– Vocoder performance with bit errors / burst errors

– Vocoder performance in presence of audio noise

– Channel entry and exit criteria (roaming algorithms)

– Infrastructure data routing and assembly algorithms

– Backhaul network performance

 These New Elements Can Create Poor Performance

Despite Seemingly Adequate C/(I+N)
