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.

3. RF Interface The RF interface of the HL8548 allows transmission of RF signals. This interface has a 50Ω nominal impedance. 3.1. Supported RF Bands The AirPrime HL8548 supports the RF bands listed in the table below. Table 2. Supported Bands RF Band Transmit band (Tx) Receive band (Rx) -
Page 11: Choosing The Correct Antenna And Cabling
Hardware Integration Guide 3.2.1. Choosing the Correct Antenna and Cabling When matching antennas and cabling: The antenna (and associated circuitry) should have a nominal impedance of 50Ω with a recommended return loss of better than 10 dB across each frequency band of operation. ... -
Page 12: Esd Guidelines
4. ESD Guidelines 4.1. SIM Card Decoupling capacitors must be added according to the drawings below as close as possible to the SIM card connectors on UIM1_CLK, UIM1_RST, UIM1_VCC and UIM1_DATA signals to avoid EMC issues and to comply with the requirements of ETSI and 3GPP standards covering the SIM electrical interface. -
Page 13: Usb
When the USB interface is externally accessible, it is required to have ESD protection on the USB_D+ and USB_D- signals. Figure 2. ESD Protection for USB Sierra Wireless recommends using a 90Ω DLP0NSN900HL2L EMC filter and an RCLAMP0503N or ESD5V3U2U-03LRH ESD diode. 4119996 Rev 1.3... -
Page 14: Legal Information
5. Legal Information 5.1. FCC Regulations The HL8548 has been granted modular approval for mobile applications. Integrators may use the HL8548 in their final products without additional FCC certification if they meet the following conditions. Otherwise, additional FCC approvals must be obtained. 1. - Page 15 4. The RF signal must be routed on the application board using tracks with a 50Ω characteristic impedance. Basically, the characteristic impedance depends on the dielectric, the track width and the ground plane spacing. In order to respect this constraint, Sierra Wireless recommends using MicroStrip or StripLine structure and computing the Tracks width with a simulation tool (like AppCad shown in the figure below and that is available free of charge at http://www.agilent.com).
