The Catalyst 9166D1 - designed for use cases and areas with high ceilings such as auditoriums, warehouses, and other large open space areas. The Catalyst 9166D1 should be leveraged where typically external antennas would be required. And because the Catalyst 9166D1 uses a built-in directional antenna, it eliminates the need for additional hardware to achieve ideal wireless coverage.
Wi-Fi 6 and Wi-Fi 6E (802.11ax)
The IEEE 802.11ax standard, also known as High-Efficiency Wireless (HEW) or Wi-Fi 6, builds on 802.11ac. It delivers a better experience in typical environments with more predictable performance for advanced applications such as 4K or 8K video; high-density, high-definition collaboration apps; all-wireless offices; and the Internet of Things (IoT). Wi-Fi 6E is Wi-Fi 6 "extended" into the 6 GHz frequency band.
XOR radio
The dual-band XOR radio in the Catalyst 9166 series enables shifting capacity between 6 GHz and a secondary 5 GHz radio.
Environmental sensors
These built-in sensors measure air quality, temperature, and humidity, and help ensure a safe working environment, avoiding the need to install an overlay of difficult-to-manage independent sensors.
AP power optimizations
AP Power optimizations (AP Power save mode) allows the access point to reduce its power consumption by e.g. shutting off radios during off-hours and weekends - whilst still being smart enough to re-engage all features should they be needed. This both saves power and reduces the carbon footprint of running a wireless network.
CleanAir Pro
CleanAir Pro applies Cisco's industry leading RF Interference detection and classification to the 2.4 GHz, 5 GHz, and 6 GHz bands.
