Typical Delay Spreads

Macrocells TRMS < 8 msec

GSM (256 kbit/s) uses an equalizer

IS-54 (48 kbit/s): no equalizer

Longer delays in mountanous regions (GSM in Switzerland)

 

 

Microcells TRMS < 2 msec

Low antennas (below tops of buildings)

 

 

Picocells TRMS < 50 nsec - 300 nsec

Indoor often 50 nsec is assumed

DECT (1 Mbit/s) works well up to 90 nsec
