This section describes all the parameters required for Wi-Fi
connectivity.
Channel Utilization
Channel utilization is a statics that represent the airtime utilization of a particular frequency or channel. The higher the channel utilization, more the traffic transmission. For best performance of the device, it is recommended that the channel utilization is less than 30%.
Overlapping Cells
Successful and smooth hand-offs can occur only if the coverage cells of adjacent access points overlap. For example, a person who is moving around while wearing a badge must be able to stay connected to the current access point while moving into the coverage area of an adjacent access point to ensure hand-off can occur without dropping packets.
Capacity Planning
Capacity refers to the maximum number of badge-to-badge calls a specific access point can support simultaneously. The ability varies according to the manufacturer, model, and firmware level of an access point.
Access Points
Vocera supports both Autonomous and Lightweight APs.
Roaming
Roaming refers seamless movement of a badge from one access point to another.
Wireless Security
This section describes security support provided by Vocera and discusses the network overhead introduced by various security methodologies.
Power
Ensure that the TX power of your access points falls within the maximum and minimum power recommended by Vocera.
Automatic Wireless Configuration
Some WLAN controllers offer automatic configuration features that allow you to dynamically adjust transmit power levels and wireless channels used by the access points.
