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.

1. Introduction The Sierra Wireless AirPrime SL8084T soldered-down module forms the radio component for the products in which it is embedded. Module-specific performance and physical characteristics are described in document [2] AirPrime SL808x Product Technical Specification and Customer Design Guidelines.
2. Power Interface 2.1. Power Supply Power is provided to the SL8084T through power and ground pins as detailed in the following table. Table 1. Power and Ground Specifications Signal/Pin Pins Type Specification Parameter Units Name Voltage range 3.30 3.60 4.30 VCC_3V6 42, 44...
Hardware Integration Guide Power Interface Mode Band Current (at 3.6V) Conditions Power Peak Average (mA) (mA) EDGE Class 12 50Ω 1800 1900 Includes USB bus current. Peak consumption averaged over 100µs. Current consumption increases by 50mA with a 6dB return loss-based load-pull. GSM mode peak current increases to 2.2A (from nominal 1.6–1.7A) with 6dB return loss-based load-pull.
Hardware Integration Guide Power Interface 2.3. Power States The SL8084T module has five power states as detailed in the following table. Table 5. Supported SL8084T Power States Host Module State Description Interface Powered Powered Enabled Active Capable of placing / receiving calls or establishing data connections on network ...
Hardware Integration Guide RF Integration Determining the Antenna’s Location 3.2.2. Consider the following points when deciding where to place the antenna: Antenna location may affect RF performance. Although the module is shielded to prevent interference in most applications, the placement of the antenna is still very important—if the host device is insufficiently shielded, high levels of broadband or spurious noise can degrade the module’s performance.
(W), trace thickness (T), and height (H) between the trace and the reference ground plane. In order to respect this constraint, Sierra Wireless recommends that a MicroStrip structure be used and trace width be computed with a simulation tool (such as AppCAD, shown in the figure below and available free of charge at http://www.avagotech.com).
