Within mobile networks there are different ways of being attached to a 3GPP PLMN (public land mobile network). This video explains the different types of attach statuses and how they can affect and influence data connections you are using.

In some applications, the ability to know the location of the unit without powering up a GPS is useful. Using the method shown in this video, an application can perform a geolocation operation through the use of a pure cell ID. This is demonstrated using the WP7607, which is a 2G/3G/4G module. However, any module can be used.

From a UE (user equipment, so a handset/module) perspective there are a number of parameters that are critical to its operation. This video explains what these numbers are, where they come from and how they are used. It is applicable to all UE's on the market.

When using the HL78 module, for network or application problems it may be necessary to be view the internal operation of the unit. To do this logging from its debug port is required. This video shows how to carry out this logging, resulting in a file that can be sent back to Sierra Wireless for analysis.
