TECHSHIP IS A GLOBAL SUPPLIER OF WIRELESS COMPONENTS
The Expedite® EU850D PCI Express Mini Card, with an integrated SIM holder, can be embedded into laptops and other devices for 3G mobile data applications. The OEM host industrial design is free of SIM slot and wiring constraints with the EU850D. This module, powered by the Qualcomm® MSM6280 diversity and equalizer chipset, offers high performance to the user and operates globally on 850, 1900 and 2100Mhz bands on HSDPA and UMTS networks.
The purpose of this document is to provide advanced design and integration information to assist in the integration planning and evaluation of Novatel EU850D. This document is intended to specify key components of the integration tools available for the Novatel Wireless line of PCI Express Mini-cards.

The module Novatel EU850D freezes after a while. What is the problem?
The module EU850D will freeze if too many AT-Commands is sent to the module in a short time. The most common thing when this happens is if a script tries to make a ppp connection, even though the module doesn't have any signal to the network. A way to avoid this is to use the command AT+CGREG to check if the module have a signal from the network every 15 seconds. When the module have service, the ppp script can be runned.
