High Performance 3x3 802.11ac Wave 2 2.4GHz/5GHz Switchable RF Single Chip Optimized for Dense Environments

The CL2437 is a future-ready, powerful, highly integrated, 3x3 802.11ac wave 2 2.4GHz/5Ghz switchable RF single chip implementing full 802.11ac Wave 2 functionality including MU-MIMO, 160MHz channel support, beamforming and 3 Spatial Streams. The CL2437 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 CL2437 significantly raises the bar on Wi-Fi performance. range and reliability.

The CL2437 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
