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.

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.

UMTS 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.

2 Product Concept

2.1. General Description

UG95 serials are embedded 3G wireless communication modules, support UTMS/HSDPA/HSUPA networks. It 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.

Table 1: UG95 Series Frequency Bands

	Module		GSM		EGSM		DCS		PCS		UMTS		UMTS		UMTS		UMTS
			850		900		1800		1900		850		900		1900		2100
UG95															

NOTE

1) UG95 indicates Data-only and Telematics versions. Data-only version does not support voice function, Telematics version supports it.

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, mobile computing devices, PDA phone and tablet PC, 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.

2.2. Directives and Standards

The UG95 module is designed to comply with the FCC statements. FCC ID: XMR201408UG95

UG95_Hardware_Design

UMTS/HSPA Module Series

UG95 Hardware Design

The Host system using UG95 should have label “contains FCC ID: XMR201408UG95”.

2.2.1. FCC Statement

Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.

2.2.2. FCC Radiation Exposure Statement

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator and your body as well as kept minimum 20cm from radio antenna depending on the Mobile status of this module usage. This module should NOT be installed and operating simultaneously with other radio.

The manual of the host system, which uses UG95, must include RF exposure warning statement to advice user should keep minimum 20cm from the radio antenna of UG95 module depending on the Mobile status.

Note: If a portable device (such as PDA) uses UG95 module, the device needs to do permissive change and SAR testing.

The following list indicates the performance of antenna gain in certificate testing.

	Part	Frequency Range (MHz)	Peak Gain	Average Gain	VSWR	Impedance
