1 Introduction

This document defines the UC15 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 UC15 module to design and set up mobile applications easily.

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 UC15 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/HSDPA Module Series

UC15 Hardware Design

GSM 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 USIM 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

UC15 is an embedded UMTS/HSDPA module. Its UMTS-based modem provides data connectivity on HSDPA, WCDMA, EDGE and GPRS networks. UC15 offers a maximum data rate of 3.6Mbps on downlink and also supports GPRS/EDGE multi-slot class 12 as well. GPRS supports the coding schemes CS-1, CS-2, CS-3 and CS-4. EDGE supports CS-1 to CS-4 and MCS-1 to MCS-9 coding schemes. UC15 includes two variants, UC15-A and UC15-E. And both of them are divided into Telematics version and Data Only version. Telematics version supports voice and data, while Data Only version only supports data. This is convenient for you to choose the dedicated type based on the wireless network configuration. The following table shows the entire radio band configuration of UC15 series.

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

With a tiny profile of 29.0mm × 29.0mm × 2.5mm, UC15 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.

UC15 is an SMD type module, which can be embedded in your application through its 108-pin pads including 68 LCC signal pads and 40 other pads.

UC15 is integrated with internet service protocols such as 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 UC15 module is designed to comply with the FCC statements. FCC ID: XMR201404UC15

If the FCC ID of the module cannot be seen by the user in the final installation, the host device must show the statement: “Contains FCC ID: XMR201404UC15” in a visible and permanent location”

2.2.1.FCC Statement

1.This device complies with Part 15 of the FCC rules. Operation is subject to the following conditions: a) This device may not cause harmful interference.

b) This device must accept any interference received, including interference that may cause undesired operation.

2.Changes or modifications not expressly approved by the party responsible for compliance could avoid 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 UC15, must include RF exposure warning statement to advice user should keep minimum 20cm from the radio antenna of UC15 module depending on the Mobile status.

Note: If a portable device (such as PDA) uses UC15 module, the device needs to do permissive change and SAR testing.
