1. Introduction
This document is the Product Technical Specification for the AirPrime HL8518, HL8528 and HL8529
Embedded Modules. It defines high level features and illustrates the interfaces for these features. This
document is intended to cover hardware aspects, including electrical and mechanical, of the AirPrime
HL8518, HL8528 and HL8529.
The AirPrime HL8518, HL8528 and HL8529 modules belong to the AirPrime HL Series from the
Essential Connectivity Module family. These are industrial grade Embedded Wireless Modules that
provide voice and data connectivity on GPRS, EDGE RX, WCDMA, HSDPA and HSUPA networks
(as listed in Table 1 Supported Bands/Connectivity).
The HL8518, HL8528 and HL8529 modules support a large variety of interfaces such as Digital Audio,
GPIOs and UART to provide customers with the highest level of flexibility in implementing high-end
solutions.

1.1. Common Flexible Form Factor (CF 3 )
The AirPrime HL8518, HL8528 and HL8529 belong to the Common Flexible Form Factor (CF 3 )
family of modules. This family consists of a series of WWAN modules that share the same mechanical
dimensions (same width and length with varying thicknesses) and footprint. The CF
3 form factor
provides a unique solution to a series of problems faced commonly in the WWAN module space as it:

Accommodates multiple radio technologies (from 2G to LTE advanced) and band groupings

Supports bit-pipe (Essential Module Series) and value add (Smart Module Series) solutions

Offers electrical and functional compatibility

Provides Direct Mount as well Socketability depending on customer needs
