Entering 2024, Wi-Fi remains a major player in the consumer and industrial IoT markets, and a big reason for its strong position is the technology's continued improvements. This year, Wi-Fi 7, the newest member of the Wi-Fi technology family, based on the IEEE 80.11be standard, should take a big step forward.

The Wi-Fi 7 standard is expected to be finalized in early 2024, and the transmission rate is expected to reach around 1.3 Gbps, which is higher than the theoretical upper limit of 1 Gbps of its predecessor Wi-Fi 6, which has a theoretical maximum rate of up to 46 Gbps. It does this through 4K QAM modulation technology, while Wi-Fi 6 uses 1K QAM. It utilizes multi-link operation, meaning it can simultaneously use the 2.4 Ghz, 5 Ghz and 6 Ghz bands for data transmission, as well as multiple-input multiple-output technology and other improvements that improve reliability and reduce latency compared to earlier products Aspects such as Wi-Fi standards will certainly make Wi-Fi 7 more attractive for commercial and industrial applications.

ABI Research said that by 2028, annual shipments of Wi-Fi-enabled chipsets will exceed 5.1 billion units, of which more than 1.7 billion chipsets support the Wi-Fi 7 standard.

Wi-Fi 7-based routers and other products have begun to appear in 2023, and just in the first week of the new year, the pace of new Wi-Fi 7 product launches seems to be accelerating. Among them, broadband service provider Lumen Technologies launched a Wi-Fi 7 router for its gigabit broadband service customers; EnGenius announced the launch of a Wi-Fi 7 cloud access point based on Qualcomm Pro 1220 Wi-Fi 7 platform; Ceva launched RivieraWaves Wi-Fi 7 IP platform. The latter platform allows Wi-Fi 7 to be integrated into system-on-chip designs for new access point and station/client products.

"Expanding Wi-Fi usage drives the Wi-Fi 7 standard to deliver enhanced data throughput, improved latency and support for more spectrum amid increasing network congestion," said Tal Shalev, vice president and general manager of Wireless Networks. ” Ceva’s IoT BU: “Achieving this requires highly sophisticated cutting-edge features such as 4K QAM modulation, multi-link operation and multiple resource units to optimize link efficiency across the available frequency bands with our RivieraWaves Wi-Fi 7 IP. Platform integration with this latest generation wireless standard greatly simplifies development and reduces time to market for companies looking to add Wi-Fi 7 connectivity to their products.”

Ceva's RivieraWaves will be available later this year and will be backwards compatible with Wi-Fi 6 and 6E standard products, as well as Wi-Fi 4 and 5 platforms.
