Wi‑Fi 7 promises faster, more reliable networks as manufacturers exploit certification loophole

The new Wi‑Fi 7 (IEEE 802.11be) standard adds 320 MHz channels, 4K‑QAM modulation and Multi‑Link Operation (MLO), allowing simultaneous use of 2.4 GHz, 5 GHz and 6 GHz bands. Proponents say it reduces drop‑outs, supports many concurrent users and enables high‑speed applications such as 4K medical imaging, cloud‑based patient data and AR‑assisted maintenance. Companies like Hecking Elektrotechnik in Germany are installing the technology in offices, clinics and industrial sites, emphasizing the need for compatible cabling and power infrastructure.

Some router makers, however, evade the Wi‑Fi Alliance’s certification by omitting the hyphen—labeling products “WiFi 7” instead of “Wi‑Fi 7”. This loophole lets them market devices without MLO, offering only modest speed gains despite a premium price. The article advises consumers to verify the “Wi‑Fi Certified 7” logo and MLO mention in specifications. In the United States, the FCC has recently restricted approval of foreign‑built hardware, affecting which manufacturers can sell certified equipment.
