The Cisco Catalyst Wireless 9162I Series Wi-Fi 6E Access Point is an enterprise-class tri-band (2.4 GHz, 5 GHz, 6 GHz) indoor access point designed for robust wireless network deployments. It supports full interoperability with both 802.11ax and 802.11ac clients, making it suitable for hybrid network environments that include other access points and controllers.
Function Description:
The primary function of the CW9162I AP is to provide high-performance Wi-Fi 6E connectivity for enterprise indoor environments. It operates across three frequency bands (2.4 GHz, 5 GHz, and 6 GHz) to maximize network capacity and reduce congestion. The AP is designed to work with Cisco 9800 wireless controllers and supports various operating modes, including Local mode (default, serving clients with central switching), FlexConnect mode (local data switching, managed by controller), Monitor mode (dedicated sensors for LBS, rogue AP detection, and IDS), and Sniffer mode (capturing and forwarding packets for analysis). It also supports Site Survey mode for configuring RF parameters.
