1. Introduction
The WM-BAC-AT-49 combo module is one of the product families in USI’s product offering, targeting
for system integration requiring a smaller form factor. It also provides the standard migration to high
data rate for USI’s current SIP customers.
The purpose of this document is defined the product specification for 802.11a/b/g/n/ac Wi-Fi with
BT5.1 combo module. All the data in this document is based on Qualcomm QCN7606 datasheet and
other documents provided from Qualcomm. The data will be updated after implementing the
measurement of the module.
This product is designated for using in embedded applications mainly in the IoT device, which required
small size and high data rate wireless connectivity.
