TECHSHIP IS A GLOBAL SUPPLIER OF WIRELESS COMPONENTS
This manual describes the Standard AT commands for User Equipment according to the 3GPP TS 27.007 standard
(version 15.4.0 Release 15)
For manual on proprietary model specific extended AT commands please refer to download section of product page.
This document contains the Linux SDK application guide.
Mobile devices using 3G and LTE are equipped with a second receive antenna for improved performance.
This second antenna is required for receive diversity and MIMO.
These concepts, with their associated benefits, requirements and test possibilities, are described in this Application Note in a Q&A format.
GPS receivers of Sierra Wireless AirPrime modules can be connected to a passive antenna (which should be physically located very close to the unit) or a remote active antenna containing an LNA, which will both improve SNR and compensate for any cable/insertion losses.
This application note describes the use of the integrated GPS active antenna powering function when available, and how to design an external powering circuit where required.
This document describes proprietary, password-protected AT commands available for Sierra Wireless AirPrimeTM MC/SL-series intelligent embedded modules. These commands are intended for use by OEMs, and are supplemental to the standard AT commands for GSM devices defined by the 3GPP (3rd Generation Partnership Project) in TS 27.007 AT command set for User Equipment (UE) and TS 27.005 Use of Data Terminal quipment—Data Circuit terminating Equipment (DTE-DCE) interface for Short Message Service (SMS) and Cell Broadcast Service (BSE).
The Sierra Wireless document UMTS Modems - Supported AT Command Reference (document number 2130617) identifies supported standard AT commands and provides details wherecommands vary from the standards. It also describes proprietary commands that are not password-protected.
