# Mobile Device Parameters

These parameters are used with the Webtrends Client Libraries for Mobile Applications to track both web and application activity associated with mobile devices. These values have a maximum length of 512 characters.

### Application Ad Click

#### WT.a_ac

`WT.a_ac=1` Indicates that an ad was clicked within a mobile application.

### Application Ad Impression

#### WT.a_ai

`WT.a_ai=1` Indicates that one or more ads was viewed in a mobile application. Typically, this parameter is used with the `WT.a_an` parameter to specify one or more ads viewed in a single application screen.

### Application Ad Name

#### WT.a_an

`WT.a_an=Name[;...]` Specifies one more names of ads presented in a mobile application. You can pass multiple ad names using semicolons to delimit the list. The maximum length for each *`Name`* is 64 bytes.

### Application Name

#### WT.a_nm

`WT.a_nm=application name` Specifies the name of a mobile application. This parameter can be used to report on the usage of different applications.

### Application Category

#### WT.a_cat

`WT.a_cat=application category` Specifies a category of mobile application such as Games, Health & Wellness, or Productivity. This parameter can be used to report on the usage of different types of apps.

### Application Publisher

#### WT.a_pub

`WT.a_pub=application publisher` Specifies the developer, publisher, or vendor for an application. This parameter is required.

### Connection Type

#### WT.ct

`WT.ct=connectionType` Specifies the connection type used to send the data. Many mobile devices go in and out of various connection states such as wifi, 3G, Edge, or 7.1G. To avoid sending a flood of this data as the connection fluctuates, the best practice is to send this parameter only once per session. The Webtrends Mobile Application Libraries use this best practice.

### Country

#### WT.g_co

`WT.g_co=Country Code` Specifies the country of origin for mobile traffic using a country code.

### Device Model

#### WT.dm

`WT.dm=device model` Specifies the model of the mobile device that an application is running on, for example the model of a mobile phone.

For example, `WT.dm=Motorola Droid` or `WT.dm=iPhone 3GS`.

### Event Time Stamp

#### WT.ets

`WT.ets=epoch time stamp` Specifies an epoch (unix) time stamp for an event. This time stamp is recorded so events that occur when a device is offline can be sent as an ordered batch when the device comes back online. For example, `WT.ets=1006725234`.

### Event Type

#### WT.ev

`WT.ev=eventType` Specifies the type of event activity on a mobile device. For example, this parameter can be used to differentiate activities such as clicks, swipes, and content views.

### Geolocation Coordinates

#### WT.gc

`WT.gc=latitude,longitude` Specifies the latitude and longitude of a mobile device.
