EMDK For Android - 6.9

Overview

The Cellular Manager (CellularMgr) controls the way a device's cellular data connection is used. This CSP is supported only on Zebra Android devices equipped with a Wireless Wide Area Network (WWAN) adapter with access a cellular data network. Attempts to use the CellularMgr on unsupported devices will return an error in the Result XML document.

The CellularMgr provides the ability to control the State (active/inactive) and Usage (enabled/disabled) of features. An option's "State" can be thought of as an "On/Off" switch; the feature is available to programs or the device user to make active or inactive as desired. The term "Usage" would be like a cover over the switch, locking it in its current position. When Usage of an option has been Disabled, the cover is closed, and the position of the switch cannot be changed by the user. Enabling Usage lifts the cover, and lets the user make Cellular features active or inactive.

Data Roaming Enable/Disable

Controls whether the device user is permitted to change the state (active/inactive) of Data Roaming on the device. When Enabled, Data Roaming can be made active or inactive by the device user. When Disabled, the device user can view the state but cannot change it.

The Data Roaming option determines whether a device can communicate over cellular data networks other than the "home" network provided by the mobile operator with which the active SIM card is affiliated. The convenience of communicating over "foreign" networks while roaming must be weighed against the roaming charges imposed by foreign carriers.

Cellular Data Limit On/Off

This is the On/Off switch for limiting cellular data (in MB per month) on the device, and the selector for applying the Android-default or a custom limitation. When Enabled using the Android default limit, the limit is the greater of 5GB or 1.2 times the value specified in the Cellular Data Warning Value parameter, to a maximum of 1TB. If the custom limit is selected, the limit is the value specified in the Cellular Data Limit Value parameter. Once the limit is reached, the cellular data connection is terminated until a new month begins or the restriction is lifted. If no value is specified with the Cellular Data Limit Value parameter, this parameter is ignored and the previously selected Cellular Data Limit State is retained.

Note: WWAN-enabled devices only

Shown if: Cellular Data State is set to "Enable"

  • MX: 6.3+

Background Data Enable/Disable

Controls whether the device user is permitted to change the state (active/inactive) of the background data usage on the device. When Enabled, background data can be made active or inactive by the device user. When Disabled, the device user can view the state but cannot change it.

Background data enablement determines whether applications that are not in the foreground are permitted to maintain a data connection over the cellular network (if they are capable of doing so). For example, some email applications continue to download messages while other apps are active or when the device's screen is turned off. When planning for cellular costs and bandwidth utilization, the convenience of having data ready "when it's asked for" must be weighed against the potential for data overage and roaming costs.
