User Manual
FAQ
What Wi-Fi standard does the Cisco CW9166I-E support?
The CW9166I-E supports the IEEE 802.11ax standard, commonly known as Wi-Fi 6E. This latest Wi-Fi generation provides improved efficiency, higher throughput, and reduced latency compared to previous standards. The '6E' designation indicates support for the 6 GHz frequency band in addition to traditional 2.4 GHz and 5 GHz bands.
How many frequency bands does this access point support?
This is a tri-band access point that operates simultaneously on three frequency bands: 2.4 GHz, 5 GHz, and 6 GHz. The tri-band design allows the access point to distribute client devices across different bands, reducing congestion and optimizing performance for both legacy devices (2.4 GHz) and modern high-throughput devices (5 GHz and 6 GHz).
What is the maximum wireless throughput of the CW9166I-E?
The CW9166I-E delivers maximum aggregate wireless throughput of 7.78 Gbit/s (7,780 Mbps) across its three radio bands. This high throughput capacity supports bandwidth-intensive applications like 4K video streaming, large file transfers, and real-time collaboration tools in enterprise environments with many connected devices.
Does this access point support Power over Ethernet (PoE)?
Yes, the CW9166I-E includes a PoE PD (Power Device) port that accepts both data and power over a single Ethernet cable. This simplifies installation by eliminating the need for a separate power outlet near the ceiling mount location. The access point requires a compatible PoE switch or injector that can deliver sufficient power for operation.
What type of Ethernet connectivity does the access point have?
The access point features one 5 Gigabit Ethernet port (5GbE) for wired connectivity. This high-speed uplink ensures the wireless network isn't bottlenecked by the wired connection, allowing the full 7.78 Gbps wireless throughput to be effectively utilized. The port uses a standard RJ-45 connector for compatibility with common Ethernet cabling.
How is this access point typically mounted and installed?
The CW9166I-E is designed for ceiling mounting in indoor commercial environments. Its square form factor fits standard ceiling grid systems, and internal antennas eliminate the need for external antenna installation. The compact 2.20-inch profile allows discreet placement above ceiling tiles, while the 3.54-pound weight is supported by standard ceiling infrastructure.
