FAQ
What Wi-Fi standard does the Cisco AP1840I support?
The Cisco Aironet AP1840I operates on the IEEE 802.11ac Wi-Fi standard, which provides high-speed wireless connectivity. It is backward compatible with earlier 802.11a, 802.11b, 802.11g, and 802.11n standards, ensuring it can work with a wide range of existing client devices while delivering improved performance for 802.11ac-capable devices.
Does this access point support Power over Ethernet?
Yes, the AP1840I includes Power over Ethernet (PoE) PD support on one of its Ethernet ports. This allows the access point to receive both data and electrical power over a single Ethernet cable from a compatible PoE switch or injector. PoE simplifies installation by eliminating the need for a separate power outlet near the mounting location.
How many Ethernet ports does the AP1840I have?
The access point features two Gigabit Ethernet RJ-45 ports. These provide wired connectivity for network uplink and additional devices. One port supports PoE PD for power, while both offer Gigabit Ethernet speeds for high-bandwidth data transfer between the access point and your network infrastructure.
What is the maximum wireless speed of this access point?
The Cisco Aironet AP1840I delivers a maximum aggregate wireless throughput of 1.69 Gbit/s across both the 2.4 GHz and 5 GHz frequency bands. This speed is achieved through 802.11ac technology and is shared among connected devices, providing sufficient bandwidth for demanding applications like video streaming, large file transfers, and real-time collaboration tools.
