Wifi adapters found at local office supply stores such as Staples or Office Depot are not sufficient for real time traffic such as voice calls.Some featues you should ensure exists in your WiFi access points are:
- VLANs - VLans allow your voice traffic to be segmented from your other network traffic and prioritized to ensure voice quality remains optimal even on a busy network.
- QOS - Quality of Service is used in conjunction with VLANs to ensure bandwidth is reserved for audio calls.
- Seamless Roaming or Zero-Handoff - As users move around a building, the access point they will use will change. With consumer grade access points, this change in access points will also have a drop in network traffic as your device connects to the new access point. This drop also causes a drop in audio for the duration in the switch over. Seamless roaming options manage this transition and maintains voice quality.
At Helia we depend on two vendors to deliver reliable voice based wireless solutions. CradlePoint routers are used for smaller locations where coverage allows a single accesspoint to be used. CradlePoint routers have features to ensure bandwidth is reserved for voice application and ensure quality remains consistant. For larger installs, Ubiquity provide a very cost effective commercial solution with the appropriate features to ensure a stable installation.
