3. On the wireless router, locate the WPS button.
The device connects to the wireless router.
Wi-Fi Advanced Features
Some additional Wi-Fi settings cannot be accessed from the user interface. They can be configured by using Wi-Fi
(CSP). Refer to EMDK documentation for the details on the Wi-Fi settings configuration using the Wi-Fi CSP.
• Auto Time Config - Using this feature, the device can sync up its time with Zebra WLAN infrastructure.
This feature works only when the device is connected to Zebra WLAN infrastructure and the feature is
enabled on the WLAN infrastructure side. Default: disabled.
• PMKID Caching - Allows the device to skip 802.1x authentication during roaming if it had previously
connected to that AP with a full 802.1x authentication. Default: disabled. Note: disable OKC when enabling
PMKID Caching.
• Opportunistic Key Caching - Use this feature to skip 802.1x authentication during roaming. The device
will go for full 802.1x authentication for the first time it connects to the network. For subsequent roaming,
the device skips 802.1x authentication. Default: enabled.
• Cisco Centralized Key Management - Allows the device to skip 802.1x and key-handshake phases
during roaming. This feature is available only when the device is connected to a Cisco infrastructure that
supports Cisco Centralized Key Management (CCKM). Default: enabled.
• Fast Transition - Fast Transition (FT) is the fast roaming standard, 802.11r. With this feature, the device
can skip 802.1x and key-handshake phases during roam. Default: enabled.
• Fast Transition Resource Information Container - Allows the device to request TSPEC as part of
reassociation frame exchange. This helps to avoid sending a separate resource request after roaming is
completed. Default: enabled.
• Power Save - The device can be configured to work in different power save modes:
• Active - Keeps the WLAN radio always in active mode (i.e. power save mode disabled).
• Power save using WMM-PS - This is the default power save mode. Device uses WMM-PS power
save method if the AP is configured to use this. If the AP is not supporting WMM-PS, the device will
use PS-Poll power save method.
• Power save using PS-Poll - In this method, the device will use PS-Poll frames to retrieve buffered
frames from the AP.
• Null Data Power Save - In Null Data Power Save (NDP), the device will stay awake for 100 ms after
the last frame is sent or received. The device will send a Null Data packet with power management bit
cleared to retrieve buffered frames from the AP.
• 802.11k - Using 802.11k, the device can discover neighbor APs and adds support for different types of
radio resource measurements. Default: enabled.
• Band Preference - The device can be configured to prefer one band over another. Default:
disabled.Subnet Roaming - When the device roams between different sub networks, if it detects that it is
roaming to a different subnet, the device will request a fresh IP address. Default: disabled.
Zebra Mobility Extensions
Zebra Mobility Extensions make use of 802.11 specifications and Zebra proprietary extensions to achieve the
highest level of performance, efficiency and reliability. The device adds support for the following Zebra Mobility
Extensions:
• Coverage Hole Detection
The device includes enhancements to the IEEE 802.11k standard. These improvements will report gaps in
signal coverage to the Zebra wireless LAN infrastructure. Network administrators can detect and mitigate
coverage gaps present in the network for greater reliability. Default: enabled.
