Key Features

802.11 ax/ac/abgn - Wi-Fi 6

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 and revolutionary, yet important, improvements.

Bluetooth 5.1

Bluetooth 5.1 is backward compatible with previous BT versions such as v5.0 and v4.2. and introduces direction finding which helps in locating your keys having Bluetooth tracker on them. It offers also "centimeter-level accuracy" in location finding. Its improved advertising mode helps smart devices to broadcast their measurements to other BT devices without connecting them. BT5.1 allows devices with limited batteries (e.g. smartwatch) to piggyback other powerful devices such as mobile phones and speeds up handshake processes with devices already paired previously.

Separate BT

The simultaneous and co-located operation of Wi-Fi and BT/BLE can degrade the performance of one or more of the radios. Recent trends and Wi-Fi 6 new capabilities are making the Wi-Fi/BT co-existence challenging in specific situations. Increased Wi-Fi transmits power level for extended range and high throughput for file transfers and/or video streaming results in a high Wi-Fi duty cycle. A dedicated BT antenna improves performance through BT not-sharing with WLAN clock cycles.

Dual Band Simultaneous

The Simultaneous Dual Band supports two separate Wi-Fi networks simultaneously using both 2.4- and 5-GHz frequency bands. It doubles the available bandwidth but also allows for a more reliable dedicated Wi-Fi network for video and gaming (5GHz) to be created. When connecting multiple devices, having two separate wireless networks avoids over-crowding and interference and allows more flexibility to make the best possible connection.

Extended and Industrial Temperature Grades

Built with end quality components from the multi-layered PCB to the front end high-quality RF, the modules qualify through both extended testing for operating temperature ranges from -20° to +70° Celsius and non-condensing operating humidity from 10% to 90%, and in true industrial environments, with high humidity and severe weather operation from -40 to +90° Celsius. They are highly integrated wireless modules, perfectly suitable for demanding industrial, outdoor and enterprise-level applications.


Less Power

A high level of integration and full implementation of power management functions minimizes system power requirements. Both WLAN and BT - BLE 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. It makes the modules a good choice for resource-constrained Internet of Things (IoT) devices

Form Factors and Antenna Diversification

The Series Chip-On-Board (CoB) Modules are available in various Form Factors with a unique certification and support, meeting the needs for different designs and diverse application areas. They have three onboard antenna connectors, two for Wi-Fi and a separate one for BT. They are flexibly designed with either IPEX or MHF4 connectors on-board. It comprises a total of 4 model variants which are making it a gamut of choice for designing demanding applications in various industries and applications.


Wi-Fi 6 Certified

Wi-Fi CERTIFIED 6modules support the capacity, efficiency, coverage, and performance required by users today in the most demanding Wi-Fi environments. Emphasizing quality connectivity in locations with hundreds or thousands of connected devices such as stadiums and other public venues, as well as corporate networks utilizing time-sensitive, high bandwidth applications, our Wi-Fi 6 modules supported networks ensure each connected device performs at an optimum level. They meet the highest standards for security and interoperability, and enable lower battery consumption, making them a solid choice for any environment, including the Internet of Things (IoT).

World Certifications

Pre-certifications are existing for all major domains (FCC, ISED Canada, EU RED, Japan), all with 5 antenna types. Optionally we offer co-sponsoring for further countries. In house support and assistance with regulatory, antenna and design. Through the module certifications and our full leverage on Qualcomm’s worldwide certification program, we are able also to help partners and customers certify their devices globally and source them in any part of the world.
