Voice Over WLAN

Join Sean Doherty as he discusses his research methods and preparations for reviewing VoWLAN (Voice over Wireless LAN) products for our Oct. 30, 2003 issue.

Evaluation Particulars

What did we consider appropriate for this review?

We considered products oriented toward delivery of enterprise-class voice telephony services using handheld devices over standards-based Wi-Fi 802.11 wireless LANs. We also considered both hardware and software phone systems, but any soft phones would have to run on a true handheld computing device. Soft phones running on Windows-based notebook computers weren't considered for our review.

Products were judged based on the following criteria:

  • Basic telephony services
  • System performance and scalability
  • Advanced voice and data features
  • Integration with voice network infrastructure
  • Integration with data network infrastructure
  • System operation and management
  • Interoperability and adherence to standards
  • Cost of ownership
Our tests evaluated the suitability of products for a range of enterprise applications. Depending on the mix of products submitted for testing, we chose to evaluate the hardware- and software-based solutions separately.
