Powerful, Highly Integrated Wi-Fi 6 (802.11ax) R2 Concurrent Dual Band 4T4R PCIe Chip 

The CL8040 is a high-performing, highly integrated Wi-Fi 6 (802.11ax) R2 single PCIe chip that delivers the best Wi-Fi network performance for its size by combining two Wi-Fi 6 radios into a single 11x11mm PCIe chip. The chip employs two concurrent dual-band Wi-Fi 6 radios with 4T4R ElasticMIMO™ architecture that can drive aggregated PHY/ Data Link speeds up to 4.8Gbps. The two independent radios can function as an access point, client, AP/CLI, connectivity + dedicated spectrum intelligent engine. 

CL8040 integrates dual MAC, dual PHY, analog and RFIC in a single package, including the required CPUs and memories to run more of the wireless LAN functions on-chip, eliminating the need for costly external memories and delivering a strong host offloading solution. Interface to the host is over a dual-lane PCIe 3.0 interface.

The CL8040 is designed to support standard based features addressing security, Quality of Service and international regulation, as well as above-standard integrated value-add functionalities based on Celeno’s embedded and edge software technologies, including the disruptive ElasticMIMO™ architecture, enabling dynamic runtime allocation of the radio chains and MIMO streams between the two radios for best performance and coverage leveraging adaptive optimization engine.
