1 1: Introduction The AirPrime HL7802 is an industrial-grade LGA 86-pad module that provides data connectivity on LTE and 2G networks. The module also provides GNSS functionality. 1.1 Accessories A hardware development kit is available for AirPrime HL78 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 Rev.
2 2: Power 2.1 Power Supply The host provides power to the AirPrime HL7802 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 HL7802 Product Technical Specification. 2.2 Module Power Modes Table 2-1 summarizes the AirPrime HL7802 module’s power modes.
3 3: RF Specifications 3.1 Supported Bands The AirPrime HL7802 operates on the frequency bands listed below: Table 3-1: LTE Frequency Band Support RF Band Transmit (Tx) Band (MHz) Receive (Rx) Band (MHz) Cat-M1 Cat-NB1 B1 1920–1980 2110–2170 Y Y B2 1850–1910 1930–1990 Y Y B3 1710–1785 1805–1880 Y Y B4 1710–1755 2110–2155 Y Y B5 824–849 869–894 Y Y B8 880–915 925–960 Y Y B9 1749.9–1784.9 1844.9–1879.
