Renesas lays out Wi-Fi roadmap based on Celeno acquisition

Technology News |
By Jean-Pierre Joosting


Renesas Electronics Corporation has unveiled plans to deliver a comprehensive set of advanced Wi-Fi offerings to complement its broad portfolio of industrial and IoT products. Renesas completed its acquisition of Celeno last year and is leveraging that technology to address a wide range of Wi-Fi client and access point applications for Wi-Fi 6/6E and Wi-Fi 7.
 
Currently, Renesas is delivering production volumes of high-performance Wi-Fi 6E access point ICs with its CL8000 family.

Renesas is also sampling a powerful, highly integrated, 2×2 Wi-Fi/BLE combo chip supporting Wi-Fi 6E tri-band switchable radio (6 GHz, 5 GHz and 2.4 GHz), 160 MHz channel bandwidth and up to 2.4 Gbps data link speed. The new low-latency, highly secure chipset includes Bluetooth and BLE 5.2 support, and addresses multimedia streaming applications, IoT gateways and cloud connected devices.

Renesas is also developing a Wi-Fi 6E chipset with unique, patented Wi-Fi Doppler imaging technology. This Wi-Fi radar technology depicts the range and doppler signature of people and objects using standard Wi-Fi signals. It eliminates the need for multiple cameras or sensors in home environments and commercial buildings. For example, it can be used to detect the presence and location of people in a room to redirect and optimize air-conditioning flows, saving on energy costs. Another example could be intrusion detection to secured facilities or connected cameras with motion sensing to activate the camera. The combined connectivity and sensing chip is currently scheduled for production in the next 18 months.

Wi-Fi 7, also known as Extremely High Throughput (EHT), will deliver significantly faster throughput by employing faster modulations and double the bandwidth. In the 6 GHz band, Wi-Fi 7 would more than the double the maximum speed and will increase speeds in the 2.4 GHz and 5 GHz band by as much as 30 percent. More importantly, some prominent features of Wi-Fi 7 will improve network reliability, latency and user experience. For example, by delivering Multi Link Operation, devices would monitor multiple links across different bands and provide consolidated operation to optimize interference and retransmission avoidance. Users will benefit from more reliable networks and from lower and more predictable latency. Wi-Fi 7 is expected to launch in 2024 with early adoption in mobile phones, computers and networking devices. Broader adoption in IoT, industrial and consumer multimedia applications will follow. 

TheWi-Fi 7 offerings will include products for home networking, IoT, industrial and consumer multimedia devices.

“Many recent developments are converging to create an era of market revolution in residential and enterprise Wi-Fi,” says Andrew Spivey, Industry Analyst at ABI Research. “Driven by a desire to take advantage of the new 6 GHz spectrum, which offers the prospect of greatly improved throughput and latency as well as reduced congestion on legacy bands, penetration of 6 GHz into Wi-Fi devices will rise rapidly in coming years. Meanwhile, the flourishing of new forms of Wi-Fi value added services such as Wi-Fi motion detection and the adoption of Wi-Fi 7 access points will accelerate following the protocols standardization in 2024, and just two years later, most 6 GHz enabled access point shipments will be supporting Wi-Fi 7.”

Renesas offers numerous Winning Combinations that combine Wi-Fi 6 and 6E chipsets integrated with a broad range of solutions from Renesas, including embedded processing, analog, power, timing and connectivity products. These engineering-vetted Winning Combinations will span applications from a High Throughput Wi-Fi 6 Router for home gateways to a Wireless IEEE 1588 implementation for 5G networks. More Winning Combos with Wi-Fi 6 are under development, including a Video IP Phone, Smart Home Security Terminal, and expansion of the Renesas Quick-Connect IoT Platform to include a Wi-Fi 6 USB stick for users to rapidly build prototypes.
 
In addition, a new Quick-Connect Wi-Fi 6 and Bluetooth Low Energy 5.2 module will be released for IoT applications that need a high bandwidth, high performance Wi-Fi 6 client with 2×2 MIMO. This fully integrated, RF-qualified module will feature a flexible footprint with both PCIe and USB interfaces, saving engineering time and streamlining procurement for faster time-to-market.
