The first commercial Wi-Fi 6 Chip-on-Board modules 

A Cob+ Class

Chip-on-Board + Carriers for a broad choice of form factors, environmental grades and antenna type implementations.

Build with QUALCOMM®

Based on the Qualcomm QCA6391 chipset, part of the FastConnect 6800 and Networking Pro architectures, the E63 Class provides in module formats the engineering power of the world leading IC Vendor.

The AIRETOS® E63 Class sets a new industry benchmark by marrying state-of-the-art Wi-Fi 6 and Bluetooth 5.1 capabilities with extended features and leading-edge design. As consumer and enterprise expectations for always-on, flawless data streaming, robust indoor and outdoor wireless connectivity coverage, and reliable security continue to dramatically grow, these advanced solutions face increasing challenges with respect to battery life, data rates, and range. The E63 Class reflects VoxMicro’s continuing commitment to leadership in the wireless connectivity era by delivering first in the market the new-generation, low-power, resilient multi-gigabit Wi-Fi 6 connectivity, fully leveraging Qualcomm’s new innovative QCA6391 connectivity Chip-on-Board (CoB).


Building on VoxMicro’s history of delivering advanced Wi-Fi solutions, the E63 Class provides an 18 modules variety of high performance, full-featured, Wi-Fi 6 Chip-on-Board solutions based on the latest 802.11ax standard. E63 Class approaches 1.8 Gbps – the highest throughput of any comparable smartphone chipset to date, as well as 1024 QAM modulation across 2.4 and 5 GHz bands combined with Dual Band Simultaneous (DBS) operation.


The essential mechanism of 8-Stream sounding allows Wi-Fi 6 mobile and computing devices to take full advantage of the growing base of 8×8 MU-MIMO Wi-Fi 6 Access Points being commercially deployed. The multi-generational, field-proven capabilities OFDMA and MU-MIMO improve spectral efficiency, capacity and help ensure seamless experiences across congested networks.


The Dual-band simultaneous 2×2 MIMO operation and 8-stream sounding enable up to double the throughput performance and up to 50 percent extended range and coverage compared to Wi-Fi 5 mobile devices. E63 advanced power-management architecture provides up to 50 percent improvement in power efficiency, compared to previous Wi-Fi generation solutions. The feature of Target Wakeup Time (TWT) supports up to 67 percent lower power consumption for streaming, Wi-Fi calling and other network-intensive applications.


The Wi-Fi Protected Access 3 (WPA-3) support goes far beyond baseline requirements, with all optional and mandatory elements of the latest Wi-Fi Security protocol (WPA-3), including WPA3-Personal, WPA3-Enterprise, WPA3-Enhanced Open, and WPA3-Easy Connect supported. OFDMA and MU-MIMO – leveraged across both 2.4 and 5GHz band, is designed to deliver significant latency reduction due to more efficient use.

Flexible Form Factor

The E63 Class Chip-On-Board (CoB) Series B, have three on board antenna connectors, two for Wi-Fi and a separate one for BT. It is offered for SMT or soldered on carriers (Series W, F and X).

Choice of Antenna

Built to meet the surging connectivity demands of today’s world and with choice in mind the CoB offers the option of IPEX or MHF4 antenna connectors on-board.

Great Regulatory

Pre-certifications for all major domains, option for co-sponsoring for further countries, in-house support to assist with regulatory, antenna and design aspects. The Series R benefits of Qualcomm’s world regulatory pre-certification.

Wi-Fi 6: faster, reliable, stronger


Wi-Fi 6 is providing faster, more reliable connections. Its ability to handle much more traffic at once comes at a critical time, as more laptops, smartphones, cameras, smart speakers, displays and other personal and IoT devices crowd networks with massive new data flows. And for the next couple of years, that is much of what you’ll come to see out of the next-generation Wi-Fi: better, faster and more reliable Wi-Fi connectivity. Decidedly evolutionary, yet important, improvements.

Evolutionary or revolutionary?

To hear technologists describe it, Wi-Fi 6 is about to transform connectivity. The next-generation Wi-Fi connectivity technology – along with the emerging 5G cellular generation – will shake up the way we connect with each other. The ability of Wi-Fi 6, or 802.11ax, to instantly route traffic – even to devices on the far reaches of very crowded networks – will also change the way we interact with our smart devices. It will even rework the way smart devices communicate with each other.


Is Wi-Fi 6 really revolutionary? Or is it evolutionary?

Wi-Fi 6 significantly enhances wireless performance across multiple vectors, providing a new and improved user experience as compared to earlier versions of Wi-Fi. To accomplish this, Wi-Fi 6 uses wholly new technologies and methods, some from the cellular world, to efficiently deliver more capacity to more devices. This increased capacity and efficiency reduce congestion for a faster, more robust, and higher quality user experience in dense deployments.


Wi-Fi 6 comes with a host of new features, and here we’ll focus on those of the highest significance in defining the premium experience. While Wi-Fi 6 is expected to ramp very quickly across many market segments and tiers, this report particularly focuses on understanding how the most advanced implementations will be defined. Among the features discussed, 8 x 8 MU-MIMO stands out as providing the most significant benefits to total system performance aligned with the promises of Wi-Fi 6.




  • Increases capacity

  • Results in higher speed per user

  • Ideal for high-bandwidth applications


  • Increases efficiency

  • Reduces latency

  • Ideal for low-bandwidth applications

Two multiuser technologies – one with origins in boosting PC connectivity and the other from the cellular world – lay together the foundation for E63 Class high performance:  MU-MIMO and OFDMA. MU-MIMO is designed to boost traffic for more complex data from smartphones and laptops and OFDMA is tailor-made for IoT, voice and other so-called “small-data” applications.


Multiuser, multiple-input multiple-output communication, or MU-MIMO, dramatically expands an ability introduced with 802.11ac (Wi-Fi 5):  this MU-MIMO generation could handle no more than four spatial streams – only downstream data – only on the 5GHz band. E63 Class Wi-Fi 6 MU-MIMO is handling up to 12 streams of both upstream and downstream data – on both 2.4GHz and 5GHz bands.


Orthogonal Frequency Division Multiple Access, or OFDMA, is one of the most important new features in E63 Class. It enables the router and client device to handle communications between multiple devices at once and uses the available spectrum much more efficiently by splitting signals between different devices based on how much of the resource they need.
