How networks affect sound quality

Remote meetings with poor quality audio are often exhausting. Misunderstandings become more likely because it’s difficult to hear nuances and other subtleties in conversation. So you want to aim for the best sound quality possible during teleconferences. The following is a quick explanation of different technical requirements for audio quality.

  • A purely mobile solution gives you great flexibility and mobility, but sometimes at the expense of sound quality. Many mobile operators now offer HD Voice in their networks, which delivers HD audio if the phone supports the technology.
  • Traditional analog telephony delivers an acceptable sound quality, but with limitations in frequency range. Sometimes known as telephone quality or narrowband.
  • VoIP, i.e., digital telephony via the data network (voice over IP), allows for extended frequency range, but with some compression. IP makes it possible to achieve superior audio quality, also called HD audio or wideband.
  • Remember that all local networks and accessories, e.g. Wi-Fi, DECT (wireless telephony) or Bluetooth®, affect the transmission capacity and can have an adverse impact on the sound quality.
  • All of Konftel’s phones and conference units offer HD audio in contexts where PBXs and networks support it.

Cordless SIP phones in the workplace: DECT vs. VoWi-Fi

Posted by Daniel Noworatzky on Jun 29, 2016 3:42:00 PM

For many types of businesses, workforce mobility is indispensable. Wireless technology allows associates to communicate internally and externally without being bound to a desk or station. Traditionally, DECT (digital enhanced cordless telecommunications) has been the technology used for this purpose. More recently, as wireless local area networks (WLANs) have become more commonplace, voice over WLAN (VoWLAN or VoWi-Fi) has emerged as an increasingly utilized technology.
