PAN9028 Wi-Fi/Bluetooth Module 2 Overview
Module Integration Guide Rev. 1.0 Page 9 of 45
2 Overview
The PAN9028 is a dual band 2.4 G z and 5 G z 802.11 a/b/g/n/ac Wi-Fi radio module with
integrated Bluetooth BR/EDR/Low Energy (LE), specifically designed for highly integrated and
cost-effective applications. The simultaneous and independent operation of the two standards
enables very high data rates (802.11ac) and low-power operation (Bluetooth LE). Integrated
power management, a fast dual-core CPU, 802.11i security standard support, and high-speed
data interfaces deliver the performance for the speed, reliability, and quality requirements of
next generation products. Tx power calibration data, Wi-Fi, and Bluetooth system parameters
are pre-stored on the One Time Programmable memory of the PAN9028 during production at
Panasonic. This simplifies passing the certification process for PAN9028 customers.
Furthermore, the module reduces design, test, and calibration effort resulting in reduced time-
to-market compared to discrete solutions.
Integrating Wi-Fi and Bluetooth wireless connectivity allows high throughput applications for
industrial devices and appliances. The combination of Wi-Fi and Bluetooth provides the highest
flexibility for connectivity.
This Module Integration Guide applies to the PAN9028 WLAN/Bluetooth combo module and the
PAN9028 mSDIO Adapter development platform.
This document is structured into two main parts:
•
The hardware integration of the PAN9028 module.
•
The PAN9028 mSDIO Adapter as an example for the module integration.
