Application :

The AirPrime HL Series is the smallest, scalable, flexible solution across 2G, 3G, and 4G* technologies, and optionally contains GNSS. The HL Series provides device manufacturers with the ability to serve different regions, across multiple network technologies, with one device design.

These modules are also ideal for applications in healthcare, point of sale terminals, fl eet management, tracking, and consumer electronics.

Advantage:
The HL Series modules are completely pin-compatible and interchangeable. The HL Series common form factor provides device manufacturers the choice of soldering down the module for efficient high-volume production or, using a snap-in socket on the same solder pads. even in completed and field-deployed devices.

Sierra Wireless effectively future-proofing remote assets, extending service quality, and saving customers time and operating costs.

The HL8528 supports quad-band GSM/GPRS and enhanced GNSS (GPS and GLONASS) and additionally supports pentaband HSDPA/HSUPA and quad-band EDGE for global coverage.
