Dedicated RF Engine offloads operations for higher performance and better analytics
You might have heard me screaming from the LinkedIn and Twitter mountaintops about how honored Cisco and the Cisco Wireless team are to have Cisco RF ASIC named the winner of the Best Enterprise Wi-Fi Network Technology Award by the WBA. However, in that moment, while I announced that Cisco won, I didn't take the opportunity to explain why.
With that in mind I pulled together this post, so you can learn a little bit more about what makes the Cisco RF ASIC so special.
Why do you need the power of Cisco's RF ASIC
Wireless, wireless, wireless…its all around us, it drives and enables us to more effectively communicate without being tied to a desk. As a result, more Wi-Fi access points are needed to support more wireless devices, introducing interference. Add to this, the explosion of IoT and you can see how adding more and more devices all clamoring for airtime, clogging up channels, and creating interference, can become an issue.
Because of this environment, Cisco has introduced the RF ASIC chipset on its Catalyst 9120 and 9130 Wi-Fi 6 access points. The RF ASIC helps organizations across industries tackle their IoT and Wi-Fi communication challenges by offloading advanced analytics capabilities and enhancing wireless communication.
The technology behind Cisco's RF ASIC
The RF ASIC is an RF Unified Engine that improves the scanning efficiency of RF bands to provide efficient real-time analytics. The RF ASIC is made up of two 28nm chips: ASIC + RFIC; these chips analyze the range of frequencies by converting RF energy into I/Q data that is passed to the baseband processor. By working together, the RF ASIC engine is capable of very high-resolution scans and deep RF analysis.
This means that tasks such as identifying granular changes in the phase and amplitude of a signal or identifying and quantifying the modulation characteristics of the sampled signals are performed easily.
Cognitive radio technology seeks out and stops sources of interference in their tracks
Sources of RF interference come from more places than your neighboring Wi-Fi, although it's a major contributing factor. As we see exponential growth in IoT device ecosystems that often share the same frequencies as our other Wi-Fi devices, developing and introducing always-on, dedicated off-channel radio scanning technology became imperative. This helps take advantage of Wi-Fi 6, ultra-low latency, and fair radio resource access in high density environments. Here's how:
The RF ASIC improves spectrum resolution with up to 25% more throughput and consistent latency for a better client experience.
Reliability & Quality of Experience
The RF-ASIC provides dedicated RF monitoring and analysis capabilities required to power Cisco's most important features. The RF-ASIC enables these features for all, providing: security, performance, location context, and operational insights without compromise. All while dramatically increasing performance and improving the user quality of experience. It's for these reasons that the Cisco RF ASIC technology was selected as the Best Wi-Fi Networking Technology of 2020 by the WBA.
