1 Product Introduction
1.1 Product Overview
RG-AP880-AR is an IEEE 802.11ax-compliant wireless access point (AP) released by Ruijie Networks for indoor scenarios
in the higher education, government, general education, finance, and business sectors. It supports four radios, among
which the 2.4 GHz band can provide a maximum access rate of 875 Mbps and the 5 GHz band can provide a maximum
access rate of 8.067 Gbps. In this way, this AC can provide a maximum access rate of 8.642 Gbps, which breaks through
the bottleneck in wireless performance.
Important factors such as the wireless network security, radio control, mobile access, Quality of Service (QoS), and
seamless roaming are fully taken into account for the RG-AP880-AR. Therefore, the RG-AP880-AR can be used together
with Ruijie's access controllers (ACs) to implement STA data forwarding, security, and access control.
The RG-AP880-AR can work in IEEE 802.11ax, 802.11ac, and 802.11n modes simultaneously. It can be mounted onto a
wall, ceiling, and other similar locations. Moreover, the RG-AP880-AR supports local power supply and power over
Ethernet (PoE), which can be selected based on power supply conditions. It is especially applicable to large campuses,
enterprise offices, hotspots, and other densely populated scenarios.
1.2 Product Appearance
The RG-AP880-AR provides four RF ports, two Ethernet copper ports, one 5 Gbps SFP port, one RJ45 console port, one
power socket for an external power adapter, one USB port, and one reset button. For the two Ethernet copper ports, LAN
1 port supports IEEE 802.3af/at/bt-compliant PoE and LAN 2/IoT port can be used to supply power to the IoT module (48
