Description :

HL8548-G is a 3G HSPA Penta band module with voice and an integrated GPS+Glonass receiver. Fall back to 2G GSM/GPRS/EDGE Quad band. Supported frequency bands: 3G 800/850/900/1900/2100 and 2G 850/900/1800/1900. Form factor: 22x23 mm, SMD LGA package. Scalability between 2G, 3G and 4G with the same small size (22x23 mm), footprint and core pin layout. Very low power consumption and the separate base band and PA power supply inputs simplifies power supply design and extend operational life for battery powered devices. Support for AirVantage management services is integrated.

As an option to soldering, adding flexibility, the HL series Snap-in socket can be soldered on the same PCB pattern.

The AirPrime® HL Series modules is the smallest, scalable, flexible solution that is interchangeable among 2G, 3G, and 4G* technologies. It provides voice and data connectivity in a single compact and easy-to-integrate form factor (22x23mm). The G version have an integrated GNSS receiver (GPS+Glonass). The compact form factor, network scalability, rich feature set and ready-to-use firmware upgrades make HL series modules ideal for industrial M2M solution designs where size and deployment longevity are important considerations.

* 4G to be released in 2015.
