Voice over Wi-Fi

Also known as VoWLAN (Voice over Wireless LAN), voice over Wi-Fi uses an 802.11 wireless LAN to carry voice conversations. Early versions of VoWLAN were dogged by poor voice quality and security concerns. However, the adoption of new standards such as high speed 802.11n, improved quality of service (QoS) and advanced security standards combined with the rapid uptake of wireless networks in businesses large and small, has seen exponential growth in demand for voice over Wi-Fi handsets.

The latest SIP handsets from various vendors interoperate comfortably with a range of IP telephony platforms and with inbuilt applications interfaces, web browser/message platform capabilities and unique features such as bar code scanners – Lone worker are becoming invaluable business tools.
