Build with QUALCOMM®

The E61 deploys the QCA61x4 wireless SoC processors, with the QCA6174with external FEMs as the most complete model. 

Single DB Wi-Fi IC, in tightly sync with BT5.

The AIRETOS® E61 Class comes with World-level Regulatory Compliance and full compatibility with the latest industry standards and advisory for regulatory adaptability, aiding swift design-to-market deployment solution for the growing consumer electronics applications. E61 Class supports high-speed Wi-Fi connectivity and enriched media experiences and has integrated RF front-end and single-ended design for simpler and low-cost design.

A high level of integration and full implementation of power management functions specified in the E61 Class minimizes system power requirements. Both WLAN and BT conserve power having several power-saving modes implemented, like MIMO-PS, UAPSD, Green-Tx, host power offload, Packet-power-save (PHY-NAP), early beacon termination.

Modules that offer World level Regulatory Compliance, designed for PC manufacturers and consumers alike. 

The E61 Class enjoys community support under Linux ATH10K and a range of drivers for Windows and Android OS.

E61 Class is originally developed and certified in the Next Generation (NGFF) also known as M.2 Form Factor (2230), which is a transition from the miniPCIe (full and half-size) to a smaller form factor – both in size and volume. An NGFF/M.2 module can utilize the full speed of PCI-Express specifications, with a bandwidth up to 1GB/s under currently PCIe 3.0 standards.

Our OxfordTEC® NGFF to mPCIe Adaptor is an innovative component, taking into account optimal performance and reduced space requirements. Combined as a Kit with our E61 Series F NGFF modules allows designs with form factor independence by unique global certification. Easy assembly and the minimal space-saving module height enable compact and efficient designs with a high degree of flexibility and adaptability.

With Wi-Fi Protected Setup™ via PIN and Push-Button (PBC), Passpoint™, Voice protocols, QFN support, 80Mhz channel bandwidth, Dynamic Frequency Selection (DFS), the AIRETOS E61 Class offers solid all-rounder level Wi-Fi module choices. 

  • Single-chip, integrated design.
  • Support for DirectConnect / Wi-Fi CERTIFIED Direct® and Miracast®
  • Systematic support by open source drivers for Linux (ATH9K) and Android.

"All-around solution for miniPCI, at optimal price."
