摘要: The system for increasing the call capacity of a wireless communications degrades voice quality connections within predetermined limit in order to increase efficiency available RF spectrum as measured by carrying this allocated spectrum. This is accomplished adjusting transmission rate speech coder at mobile subscriber unit and/or that may be located switching center so therefore increased. Additionally, situation blocking monitored determine if frame error targets should adjusted further capacity. At times when not experiencing peak usage, restored normal levels. term “mobile unit” does imply restricted moving vehicle. present state art includes use units fixed applications an alternative traditional wire telephony services.
