About This Guide

This guide is jointly authored by Zebra Technologies and Cisco Systems Inc.

This guide provides recommendations for voice deployment using the following mobile computers, where the WLAN network employs access point hardware of up to dual-band (2.4GHz, 5GHz).

If the WLAN network employs access point hardware that supports and enables 6GHz (tri-band), refer to Best Practices for Wi-Fi 6E (Tri-Band) including Voice, with Cisco WLAN Infrastructure.

Mobile devices listed in the WiFi6E column in the following table seamlessly operate and connect as a WiFi6 device in a WLAN of dual-band APs.

The terms MU-MIMO (Multi-User Multi-Input-Multi-Output) and DBS (Dual Band Simultaneous) are detailed in Device RF Capabilities. Devices without “” support full Enterprise quality experience out of the box and include all device WiFi configurability options. Devices with “” require a Zebra mDNA license for full Enterprise quality experience and configurability.
