Compact, Flexible, and Future
Proof 2G, 3G, and 4G Essential
Modules
Sierra Wireless AirPrime® HL embedded modules offer everything
device manufacturers need to meet essential connectivity requirements
for machine-to-machine (M2M) applications such as healthcare, point of
sale terminals,  eet management, tracking, and consumer electronics.
Key differentiators include a common form factor, small size, low-power
consumption, enhanced RF performance, optional GNSS (GPS and
GLONASS), and worldwide coverage.
COMPACT: THE SMALLEST 2G TO 4G FORM FACTOR ON THE MARKET
The HL Series is the smallest module on the market sharing a common
form factor across 2G, 3G, and 4G technologies. Now, with just one
PCB design, device manufacturers can easily integrate voice and data
connectivity and deploy in any region, on any wireless mobile network.
FLEXIBLE: SOLDER DOWN OR CHOOSE THE SNAPIN SOCKET TO SWITCH
MODULES ANY TIME
The compact form factor offers the choice of soldering down the module
for ef cient high-volume production or, using a snap-in socket on the
same solder pads for total  exibility in prototyping or smaller volume
runs. The innovative snap-in socket allows device manufacturers to
deploy or change modules at any point in the production and product life
cycles.
FUTURE PROOF: INTELLIGENT PINTOPIN COMPATIBILITY TO SUPPORT
EVOLVING TECHNOLOGIES
The core and extension pins on the common form factor enables forward
and backward compatibility between the different 2G, 3G, and 4G
module variants. This means that the mechanical pin location delivers the
same function across the series. The optional custom pins allow for new
features as technology evolves making it the most future proof module on
the market.

EASY TO INTEGRATE AND MANAGE
e HL Series can be managed remotely
with AirVantage® Management Service,
enabling device manufacturers to securely
upgrade device fi rmware over-the-air.  is
can extend the life of your products and
solutions by future-proofi ng remote assets,
expanding service quality, and saving
customers time and operating costs.
e more we talked with Sierra Wireless,
the more confi dent we became that they
really understood what we needed to not
only build and launch a new generation
of outdoor lighting fi xtures, but to also
grow and evolve them over time.
