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 7 / 67
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.
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.
UG95 Hardware Design
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 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
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

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.
