1. Introduction
1.1 overview
Alinket ALX85X Controller Family, which has Wi-Fi 802.11a/b/g/n functionalities, is a
portfolio of low-powered, self-contained, embedded wireless module solutions that address the
connectivity demands of machine to machine applications.
ALX85X supports either an on-board ceramic antenna or a U.FL connector which provides the
flexibility for customer to pick up its own proper external antenna.
Here then, ALX85Xproduct family has mainly two types in terms of antenna configuration.
