The QCA4002 and QCA4004

The QCA4002 and QCA4004 are full-featured, dual-band, single stream 802.11n solutions that serve as a highly integrated Wi-Fi link with an energy efficient on board power amplifier (PA) and LNA. RF switches are also integrated for the 2.4 GHz band. The QCA4002 and QCA4004 are optimized for low system cost by minimizing the number of components required to achieve a reliable Wi-Fi link. In addition, the QCA4004 can operate in a pure hostless mode of operation.

The AR4100

The AR4100 is a small form factor, single stream, 802.11n Wi-Fi System In Package (SIP) solution designed for the Internet of Everything. It leverages Qualcomm Atheros’ Align technology that provides long range communications at the lowest possible power consumption.

Internet of Things (IoT), Internet of Everything (IoE)

Intelligraphics suite of drivers for Qualcomm Atheros IoT, IoE Wi-Fi chipsets were designed specifically for applications that place a high priority on low system cost, low power consumption, ease of use, and fast wake-up times. Our drivers support applications on small footprint Operating Systems, Real Time Operating Systems (RTOS) and “No OS” super loop architectures. They are designed to be compatible with Freescale, TI, Atmel, Renesas, STMicro, PIC, Energy Micro and any ARM core processor and can be quickly and easily ported to other MCU’s.
