TÜV SÜD’s Automated Regulatory Test System reduces test time

All wideband transmission systems operating in the 2.4 GHz and 5 GHz bands must be tested to demonstrate compliance against ETSI EN 300 328 for the 2.4 GHz band and ETSI EN 301 893 for the 5 GHz band.

To help support module manufactures and final product manufacturers integrating Radio modules, TÜV SÜD have engineered an automated test system capable of performing testing in accordance with ETSI EN 300 328 and ETSI EN 301 893 under the Radio Equipment Directive (RED) for CE marking and Radio Equipment Regulation for UKCA marking.

This new system reduces test time and your time to market, advantages for the customer include:

• Fast testing and de-bugging
• Remote and automated control of the chipset
• Testing in multiple modes enabling tuning for optimum performance
• Prompt notifications of test failures or issues

Update: Wi-Fi 6E is here!

Wi-Fi 6E has an “extended” spectrum in the 6 GHz band for unlicensed use. With Wi-Fi 6E, consumers have access to an additional 1200 MHz of spectrum. Consumers will need a Wi-Fi 6E router and a Wi-Fi 6E device, such as a smartphone or computer, to take advantage of the 6 GHz channels.

Any device that previously had 2.4 and 5 GHz Wi-Fi capabilities, i.e., Access Points (Indoor and Outdoor), and client devices like cell phones, tablets, etc., will want to take advantage of this added spectrum for better performance of their devices.

The benefits of Wi-Fi 6E are more reliable Wi-Fi connection, reduced spectrum congestion and less interference from non-Wi-Fi devices. Wi-Fi 6 will be over two-and-a-half times faster than the current standard and will offer better performance for consumers. Opening the 6 GHz band for unlicensed use will also increase the amount of spectrum available for Wi-Fi by nearly a factor of five and help improve rural connectivity.

The frequency allotment of each Wi-Fi 6E U-NII band (Unlicensed National Information Infrastructure) that has been added is as follows:

• U-NII-5 = 5925 to 6425 MHz which is a total of 500 MHz
• U-NII-6 = 6425 to 6525 MHz which is a total of 100 MHz
• U-NII-7 = 6525 to 6875 MHz which is a total of 350 MHz
• U-NII-8 = 6875 to 7125 MHz which is a total of 250 MHz

The Federal Communications Commission (FCC) have adopted rules that this 1200 megahertz of spectrum in the 6 GHz band (5.925 to 7.125 GHz) available for unlicensed use. These new rules will usher in this next generation of Wi-Fi, and play a major role in the growth of the Internet of Things.

TÜV SÜD’s testing and certification services allow manufacturers to ensure that their products comply with the FCC’s changing requirements without affecting their product development timelines.
