Fourth Generation Vocoder™ (4GV™)

Overview

Qualcomm’s Fourth Generation Vocoder™, or 4GV™, is a core voice codec suite that enables network operators to dynamically prioritize voice quality and network capacity. 4GV offers dramatically enhanced network capacity by up to 40 percent with only a software upgrade. When deployed in conjunction with receive diversity, capacity gains are even more dramatic.

Fully supported by select Mobile Station Modem™ (MSM™) chipsets, the 4GV solution also increases the overall quality of end-to-end services for delay-sensitive applications such as Voice over Internet Protocol (VoIP). As user demand for data-intensive applications continues to grow, 4GV delivers network operators the ability to accommodate new needs while leveraging their existing investments into 3G networks.

Benefits

  • Significantly increases network capacity up to 40% while maintaining voice quality
  • Allows operators to dynamically prioritize voice quality or network capacity tradeoff with flexibility
  • Incremental software upgrade simplifies deployment and reduces overall costs
  • Compressed bandwidth allows for more calls per channel
  • Complements subscriber growth while users experience fewer blocked calls
  • Eliminates churning by enabling consistent voice services
  • Cost-effective solution designed to support future voice services and applications
  • 3GPP2 approved standard as EVRC-B with support of major operators and infrastructure manufacturers
  • Offers flexible deployment options:
  • 4GV Narrowband (EVRC-B)
    • Enables up to 40% network capacity increase while maintaining consistent voice quality
    • Provides operators with the flexibility to dynamically prioritize voice quality or network capacity
  • 4GV Wideband (EVRC-WB)
    • Offers superior voice quality enhancements for mobile users without sacrificing existing voice capacity
  • 4GV VoIP (EVRCB, EVRCWB)
    • Delivers better voice quality over packet networks through integrated Quality of Service (QoS) features, all within the core of the codec by inception
    • Enhances simultaneous voice data services and future multimedia services such as videotelephony, streaming, gaming and ringback tones.
