Important Notice

Safety and Hazards

Due to the nature of wireless communications, transmission and reception of data can never be guaranteed. Data may be delayed, corrupted (i.e., have errors) or be totally lost. Although significant delays or losses of data are rare when wireless devices such as the Sierra Wireless modem are used in a normal manner with a well-constructed network, the Sierra Wireless modem should not be used in situations where failure to transmit or receive data could result in damage of any kind to the user or any other party, including but not limited to personal injury, death, or loss of property. Sierra Wireless accepts no responsibility for damages of any kind resulting from delays or errors in data transmitted or received using the Sierra Wireless modem, or for failure of the Sierra Wireless modem to transmit or receive such data.

Do not operate the Sierra Wireless modem in areas where blasting is in progress, where explosive atmospheres may be present, near medical equipment, near life support equipment, or any equipment which may be susceptible to any form of radio interference. In such areas, the Sierra Wireless modem MUST BE IN AIRPLANE MODE OR POWERED OFF. The Sierra Wireless modem can transmit signals that could interfere with this equipment.

Do not operate the Sierra Wireless modem in any aircraft, whether the aircraft is on the ground or in flight. In aircraft, the Sierra Wireless modem MUST BE IN AIRPLANE MODE OR POWERED OFF. When operating, the Sierra Wireless modem can transmit signals that could interfere with various onboard systems.

Limitation of Liability

Note: Some airlines may permit the use of cellular phones while the aircraft is on the ground and the door is open. Sierra Wireless modems may be used at this time.

The driver or operator of any vehicle should not operate the Sierra Wireless modem while in control of a vehicle. Doing so will detract from the driver or operator's control and operation of that vehicle. In some states and provinces, operating such communications devices while in control of a vehicle is an offence.

The information in this manual is subject to change without notice and does not represent a commitment on the part of Sierra Wireless. SIERRA WIRELESS AND ITS AFFILIATES SPECIFICALLY DISCLAIM LIABILITY FOR ANY AND ALL DIRECT, INDIRECT, SPECIAL, GENERAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES INCLUDING, BUT NOT LIMITED TO, LOSS OF PROFITS OR REVENUE OR ANTICIPATED PROFITS OR REVENUE ARISING OUT OF THE USE OR INABILITY TO USE ANY SIERRA WIRELESS PRODUCT, EVEN IF SIERRA WIRELESS AND/OR ITS AFFILIATES HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES OR THEY ARE FORESEEABLE OR FOR CLAIMS BY ANY THIRD PARTY.

Notwithstanding the foregoing, in no event shall Sierra Wireless and/or its affiliates aggregate liability arising under or in connection with the Sierra Wireless product, regardless of the number of events, occurrences, or claims giving rise to liability, be in excess of the price paid by the purchaser for the Sierra Wireless product.

1: Introduction

The AirPrime WP7702 is an industrial-grade LGA 239-pad module that provides voice and data connectivity on LTE networks. The module also provides GNSS functionality as a SKU-configuration.

Accessories

A hardware development kit is available for AirPrime WP-series modules. The kit contains hardware components for evaluating and developing with the module, including:

• Development board

• Cables

• Antennas (Additional antennas may be required to support all bands.)

• Other accessories

2: Power

Power Supply

The host provides power to the AirPrime WP7702 through multiple power and ground pins. The host must provide safe and continuous power at all times; the module does not have an independent power supply, or protection circuits to guard against electrical issues.

For detailed pinout and voltage/ current requirements of this module, see the AirPrime WP7700/WP7702 Product Technical Specification.

Module Power States

The module has three main power states, as described in Table 2-1.

Table 2-1: Supported Power States

State Description Wake-Up Events

OFF

Interrupt

Active

Module is off (no power to the system). Apply power for system to go to Active state.

Simple wakeup sources are configured to interrupt from this power-saving state to the Active state.

The module may be fully functioning (WWAN radio and GNSS radio active), or be operating in airplane mode (WWAN radio off).

Module actively reduces power consumption by disabling components that are not in use (for example, stepping down clock signals, putting USB bus into selective suspend, etc.)

Apply power.

An event generated from a state change of RESET_IN_N or POWER_ON_N, or a timeout event.

System wakes up (returns to fully active mode) automatically as required, or can be woken directly via wakeable GPIOs.
