High Performance 4x4 802.11ac Wave 2 5GHz Single Chip Optimized for Dense Environments

The CL2440 is a future-ready, powerful, highly integrated, 4x4 802.11ac wave 2 single chip implementing full 802.11ac Wave 2 functionality including MU-MIMO, 160MHz channel support, beamforming and 4 Spatial Streams. The CL2440 integrates both a CPU and memory to run more of the wireless LAN functions on-chip, delivering a strong host offloading solution with no need for costly external memories. Designed for fit, the CL2440 comes in a compact 88 pin QFN enabling a full 4x4 high performance 802.11ac interface in a standard full-sized min PCIe card with the lowest power consumption.

Employing new MAC and PHY improvements to perfect throughput in dense environments, the CL2440 significantly raises the bar on Wi-Fi performance. range and reliability.

The CL2440 integrates above standard value-add functionalities based on Celeno’s embedded and edge software technologies. These include:

  • Argus in-silicon RF and DSP-based spectrum analyzer and intelligence engine that seamlessly scans spectrum without interrupting service and without the need for additional RBOM costs
  • Smart Antenna Steering (SAS) to enhance performance and coverage in different environments and at different ranges, both horizontally and vertically
  • OptimizAIR® technology enabling provisioning, enforcement and dynamic allocation of Wi-Fi resources per multiple virtual network (SSID), per service, per device and per traffic direction all served by the same Wi-Fi access point
  • ControlAIR® smart multi-AP Wi-Fi controller software enabling harmonious and synchronized co-existence among multiple AP deployments
