1 Introduction

This document defines the UG95 module and describes its hardware interface which are connected with your application and the air interface.

This document can help you quickly understand module interface specifications, electrical and mechanical details. Associated with application notes and user guide, you can use UG95 module to design and set up mobile applications easily.

UG95_Hardware_Design Confidential / Released 8 / 72

UMTS/HSPA Module Series

Full attention must be given to driving at all times in order to reduce the risk of an accident. Using a mobile while driving (even with a handsfree kit) cause distraction and can lead to an accident. You must comply with laws and regulations restricting the use of wireless devices while driving.

Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it switched off. The operation of wireless appliances in an aircraft is forbidden to prevent interference with communication systems. Consult the airline staff about the use of wireless devices on boarding the aircraft, if your device offers a Airplane Mode which must be enabled prior to boarding an aircraft.

Switch off your wireless device when in hospitals or clinics or other health care facilities. These requests are desinged to prevent possible interference with sentitive medical equipment.

Cellular terminals or mobiles operate over radio frequency signal and cellular network and cannot be guaranteed to connect in all conditions, for example no mobile fee or an invalid SIM card. While you are in this condition and need emergent help, please remember using emergency call. In order to make or receive call, the cellular terminal or mobile must be switched on and in a service area with adequate cellular signal strength.

Your cellular terminal or mobile contains a transmitter and receiver. When it is ON , it receives and transmits radio frequency energy. RF interference can occur if it is used close to TV set, radio, computer or other electric equipment.

In locations with potencially explosive atmospheres, obey all posted signs to turn off wireless devices such as your phone or other cellular terminals. Areas with potencially exposive atmospheres including fuelling areas, below decks on boats, fuel or chemical transfer or storage facilities, areas where the air contains chemicals or particles such as grain, dust or metal powders.

1.1. Safety Information

The following safety precautions must be observed during all phases of the operation, such as usage, service or repair of any cellular terminal or mobile incorporating UG95 module. Manufacturers of the cellular terminal should send the following safety information to users and operating personnel and to incorporate these guidelines into all manuals supplied with the product. If not so, Quectel does not take on any liability for customer failure to comply with these precautions.

2 Product Concept

2.1. General Description

UG95 series are embedded 3G wireless communication modules, support GSM/GPRS/EDGE and UMTS/HSDPA/HSUPA networks. They can also provide voice functionality1) for your specific application. UG95 offers a maximum data rate of 7.2Mbps on downlink and 5.76Mbps on uplink in HSPA mode. GPRS supports the coding schemes CS-1, CS-2, CS-3 and CS-4. EDGE supports CS1-4 and MCS1-9 coding schemes. UG95 contains two variants UG95-A and UG95-E. You can choose the dedicated type based on the wireless network configuration. The following table shows the entire radio band configuration of UG95 series.

Table 1: UG95 Series Frequency Bands

More details about GPRS/EDGE multi-slot configuration and coding schemes, please refer to Appendix B, C and D.

With a tiny profile of 23.6mm × 19.9mm × 2.2mm, UG95 can meet almost all requirements for M2M application such as automotive, metering, tracking system, security solutions, routers, wireless POS, etc..

UG95 is an SMD type module, which can be embedded in application through its 102 LGA pads.

UG95 is integrated with internet service protocols like TCP/UDP and PPP. Extended AT commands have been developed for you to use these internet service protocols easily.
