ADAPTIVE/DYNAMIC MODULATION 

The modulation (4-QAM or 16/32-QAM) is selected based on propagation 

condition. 

With this feature it’s possible to double (or more) the capacity in normal 

propagation condition using high density modulation in the same channel 

bandwidth. 

THIS FEATURE PERFECTLY FITS NEW HSDPA SERVICES 

High density: clear sky condition (high & low QoS traffic) 

• Modulation: 

• Traffic: 

16/32-QAM 

voice + high speed packet data 

Normal density: bad weather condition (high QoS traffic + best effort traffic) 

• Modulation:
