1 Introduction

This document defines BG95 module and describes its air interface and hardware interfaces which are

connected with customers’ applications.

This document can help customers quickly understand the interface specifications, electrical and

mechanical details, as well as other related information of BG95. To facilitate its application in different

fields, reference design is also provided for customers’ reference. Associated with application notes and

user guides, customers can use the 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 BG95. Manufacturers of the cellular

terminal should send the following safety information to users and operating personnel, and incorporate

these guidelines into all manuals supplied with the product. If not so, Quectel assumes no liability for

customers’ 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) causes

distraction and can lead to an accident. Please comply with laws and regulations

restricting the use of wireless devices while driving.

Switch off the cellular terminal or mobile before boarding an aircraft. The operation

of wireless appliances in an aircraft is forbidden to prevent interference with

communication systems. If the device offers an Airplane Mode, then it should be

enabled prior to boarding an aircraft. Please consult the airline staff for more

restrictions on the use of wireless devices on boarding the aircraft.

Wireless devices may cause interference on sensitive medical equipment, so

please be aware of the restrictions on the use of wireless devices when in

hospitals, clinics or other healthcare facilities.

Cellular terminals or mobiles operating over radio signals and cellular network

cannot be guaranteed to connect in all possible conditions (for example, with

unpaid bills or with an invalid (U)SIM card). When emergent help is needed in such

conditions, please remember using emergency call. In order to make or receive a

call, the cellular terminal or mobile must be switched on in a service area with

adequate cellular signal strength.

The cellular terminal or mobile contains a transmitter and receiver. When it is ON, it

receives and transmits radio frequency signals. RF interference can occur if it is

used close to TV set, radio, computer or other electric equipment.

In locations with potentially explosive atmospheres, obey all posted signs to turn

off wireless devices such as your phone or other cellular terminals. Areas with

potentially explosive atmospheres include fueling 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, etc.

1.2. FCC Certification Requirements.

According to the definition of mobile and fixed device is described in Part 2.1091(b), this device is a

mobile device.

And the following conditions must be met:

1. This Modular Approval is limited to OEM installation for mobile and fixed applications only. The antenna

installation and operating configurations of this transmitter, including any applicable source-based time-

averaging duty factor, antenna gain and cable loss must satisfy MPE categorical Exclusion Requirements

of 2.1091.

2. The EUT is a mobile device; maintain at least a 20 cm separation between the EUT and the user’s

body and must not transmit simultaneously with any other antenna or transmitter.

3.A label with the following statements must be attached to the host end product: This device contains

FCC ID: XMR201910BG96M3.

4.To comply with FCC regulations limiting both maximum RF output power and human exposure to RF

radiation, maximum antenna gain (including cable loss) must not exceed:

❒ GSM850:≤8.571 dBi

❒ GSM1900:≤10.030dBi

❒ Catm LTE Band2/25:≤11.000dBi

❒ Catm LTE Band4/66:≤8.000dBi

❒ Catm LTE Band5/26:≤12.541dBi

❒ Catm LTE Band12/85:≤11.798dBi

❒ Catm LTE Band13:≤12.214dBi

❒ Catm LTE Band14:≤12.272 dBi

❒ NB LTE Band2/25:≤11.000dBi

❒ NB LTE Band4/66:≤8.000dBi

❒ NB LTE Band5/26:≤12.541dBi

❒ NB LTE Band12/85:≤11.798dBi

❒ NB LTE Band13:≤12.214dBi

❒ BNLTE Band14:≤12.272 dBi

LPWA Module Series

BG95 Hardware Design

BG95_Hardware_Design 11 / 80

❒NB LTE Band71:≤11.687 dBi

5. This module must not transmit simultaneously with any other antenna or transmitter

6. The host end product must include a user manual that clearly defines operating requirements and

conditions that must be observed to ensure compliance with current FCC RF exposure guidelines.

For portable devices, in addition to the conditions 3 through 6 described above, a separate approval is

required to satisfy the SAR requirements of FCC Part 2.1093

If the device is used for other equipment that separate approval is required for all other operating

configurations, including portable configurations with respect to 2.1093 and different antenna

configurations.

For this device, OEM integrators must be provided with labeling instructions of finished products.

Please refer to KDB784748 D01 v07, section 8. Page 6/7 last two paragraphs:

A certified modular has the option to use a permanently affixed label, or an electronic label. For a

permanently affixed label, the module must be labeled with an FCC ID - Section 2.926 (see 2.2

Certification (labeling requirements) above). The OEM manual must provide clear instructions

explaining to the OEM the labeling requirements, options and OEM user manual instructions that are

required (see next paragraph).

For a host using a certified modular with a standard fixed label, if (1) the module’s FCC ID is not visible

when installed in the host, or (2) if the host is marketed so that end users do not have straightforward

commonly used methods for access to remove the module so that the FCC ID of the module is visible;

then an additional permanent label referring to the enclosed module:“Contains Transmitter Module

FCC ID: XMR201910BG96M3” or “Contains FCC ID: XMR201910BG96M3” must be used. The host

OEM user manual must also contain clear instructions on how end users can find and/or access the

module and the FCC ID.

LPWA Module Series

BG95 Hardware Design

BG95_Hardware_Design 12 / 80

The final host / module combination may also need to be evaluated against the FCC Part 15B criteria

for unintentional radiators in order to be properly authorized for operation as a Part 15 digital device.

The user’s manual or instruction manual for an intentional or unintentional radiator shall caution the

user that changes or modifications not expressly approved by the party responsible for compliance

could void the user's authority to operate the equipment. In cases where the manual is provided only in

a form other than paper, such as on a computer disk or over the Internet, the information required by

this section may be included in the manual in that alternative form, provided the user can reasonably be

expected to have the capability to access information in that form.

This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:

(1) This device may not cause harmful interference, and (2) this device must accept any interference

received, including interference that may cause undesired operation.

Changes or modifications not expressly approved by the manufacturer could void the user’s authority to

operate the equipment.

might reduce in their value and exceed the specified tolerances. When the temperature returns to

the normal operating temperature levels, the module will meet 3GPP specifications again.

1. eSIM function is optional. If eSIM is selected, then the external (U)SIM cannot be used

simultaneously.

2. RESET_N will be supported in the next hardware design version.

3. ADC0 and ADC1 cannot be used simultaneously. BG95 supports using of only one ADC interface at a

time: either ADC0 or ADC1. Currently only ADC0 is enabled, and ADC1 will be enabled in the next

hardware design version.

4. “*” means under development.

2.4. Evaluation Board

In order to help customers to develop applications conveniently with BG95, Quectel supplies the

evaluation board (EVB), USB to RS-232 converter cable, USB data cable, earphone, antenna and other

peripherals to control or test the module. For more details, please refer to document [1].
