High Performance 4x4 802.11ac 2.4 GHz RF Single Chip Optimized for Dense Environments

The CL2442 is a future-ready, powerful, highly integrated, 4x4 802.11ac single chip implementing 802.11ac functionality including beamforming and 4 Spatial Streams. The CL2442 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. Employing new MAC and PHY improvements to perfect throughput in dense environments, the CL2442 significantly raises the bar on Wi-Fi performance. range and reliability.

The CL2442 integrates above standard value-add functionalities based on Celeno’s edge software technologies. These include:

  • 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 serve by the same Wi-Fi access point
