Introduction

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

• Full IEEE 802.11a/b/g/n/ac legacy compatibility.

OEM Integrators Installation Manual

2.1 Important Notice to OEM integrators

1. This module is limited to OEM installation ONLY.
2. This module is limited to installation in mobile or fixed applications, according to Part 2.1091(b).
3. The separate approval is required for all other operating configurations, including portable configurations with respect to Part 2.1093 and different antenna configurations
4. For FCC Part 15.31 (h) and (k): The host manufacturer is responsible for additional testing to verify compliance as a composite system. When testing the host device for compliance with Part 15 Subpart B, the host manufacturer is required to show compliance with Part 15 Subpart B while the transmitter module(s) are installed and operating. The modules should be transmitted and the evaluation should confirm that the module’s intentional emissions are compliant (i.e. fundamental and out of band emissions). The host manufacturer must verify that there are no additional unintentional emissions other than what is permitted in Part 15 Subpart B or emissions are compliant with the transmitter(s) rule(s).

Antenna Installation

1. The antenna must be installed such that 20 cm is maintained between the antenna and users.
2. The transmitter module may not be co-located with any other transmitter or antenna.
3. To comply with FCC/IC regulations limiting both maximum RF output power and human exposure to RF radiation, the maximum antenna gain including cable loss in a mobile exposure condition must not exceed:

Peak gain of WiFi Antenna:

• 3.18 dB @ 2.4 GHz Band
• 2.67 dBi @ 5.15GHz ­ 5.25GHz
• 2.27 dBi @ 5.25GHz ­ 5.35GHz
• 2.07 dBi @ 5.47GHz ­ 5.725GHz
• 1.78 dBi @ 5.725GHz ­ 5.85GHz

Peak gain of Bluetooth Antenna :
1.23 dB @ 2.4 GHz Band

In the event that these conditions cannot be met (for example certain laptop configurations or colocation with another transmitter), then the FCC/IC authorization is no longer considered valid and the FCC ID/IC ID cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC/IC authorization.
2.2 Antenna Configurations
There are four antenna configurations for the WM-BAC-AT-49 module as followings Configuration 1:

It can be found there are two different WiFi antennas (WiFi ANT A and B) and only one Bluetooth antenna with different cable lengths could be used among the above four configurations. The worst-case for the AT-49 module will be configuration 3 due to the minimum cable length and maximum antenna gain happened. The OEM integrators should make sure the maximum antenna gain including cable loss must not exceed the list on page 4.

2.4 Note Information
USI uses various test mode programs for test set up which operate separately from production firmware. Host integrators should contact USI for assistance with test modes needed for module/host compliance test requirements.
The WN-BAC-AT-49 module is only verified for FCC/IC/CE compliance by using the dipole antennas list in above sections 2.2 and 2.3. And the antenna shall not be modified or exceed the maximum gain list in section 2.3. Separate approval is required for all other operating configurations, including different antenna configurations.
