EFJohnson Subsidiary Implements Enhanced Vocoder Technology into its Project 25 Compliant Radios
Earlier this month, EFJ, Inc. (NASDAQ: EFJI) announced that its EFJohnson subsidiary has implemented the new Enhanced Project 25 Vocoder into its Project 25 compliant portable and mobile radios. EFJohnson is believed to be one of the first Project 25 land mobile radio vendors to implement the new Vocoder.
“A digital voice coder, or Vocoder, is important because it determines the speech quality performance of a communication system,” said Michael E. Jalbert, chairman and chief executive officer of EFJ, Inc. “Implementing this latest generation technology into our radios significantly improves voice quality and audio performance.” According to Dr. John C. Hardwick, president of Enhanced Project 25 Vocoder developers Digital Voice Systems Inc. (DVSI), “Our patented Enhanced P25 Vocoder includes many enhancements that significantly increase voice quality and robustness for demanding public safety applications: recent independent speech quality testing shows DVSI’s Enhanced P25 Vocoder achieves substantially higher voice quality in virtually all test conditions, significantly better performance in background noise, and full interoperability with the P25 Vocoder standard (TIA-102BABA).” The company is already shipping the Enhanced P25 Vocoder technology in its radios, Jalbert added.
