Ruijie RG-AP840-L AX5400 Wi‑Fi 6 Indoor Access Point, 5Gb Uplink, PoE

An introduction to the Ruijie RG-AP840-L and its key features

The Ruijie RG-AP840-L is an enterprise-grade indoor Wi‑Fi 6 access point designed to meet the demands of modern high-density environments. Marketed as an AX5400-class AP, it combines a 2.4 GHz 2×2 radio and a 5 GHz 4×4 radio to deliver up to six spatial streams and an aggregate peak throughput in the AX5400 range. Key differentiators include dual 5 Gbps uplink options (SFP/RJ45 combo and a separate multi-gig RJ45 service port), broad PoE power support (802.3af/at/bt), Bluetooth 5.1 for location and IoT use, and flexible management via Ruijie Cloud or traditional on-premises controller modes. With a suggested price of $399, the RG-AP840-L aims to deliver enterprise features and modern uplink flexibility at a competitive price point.

Detailed specifications and benefits

• Radios:Dual-radio design — 2.4 GHz (2×2) + 5 GHz (4×4).
• Spatial streams:Up to six spatial streams (combining 2×2 and 4×4).
• Peak throughput:Approx. 5.378 Gbps combined, placing it in the AX5400 performance class.
• Advanced PHY/MAC features:OFDMA, MU‑MIMO, 1024‑QAM and 160 MHz channel support on 5 GHz where regulation and spectrum allow.
• Antenna:Built-in omnidirectional antennas, suitable for ceiling and wall deployments in typical indoor environments.

Benefit: The combination of OFDMA and MU‑MIMO maximizes spectrum efficiency and simultaneous client throughput, which matters most in lecture halls, meeting rooms and dense office floors. Support for 160 MHz and 1024‑QAM helps high‑bandwidth clients reach peak speeds when conditions permit.

• 5 Gbps combo uplink:1 × 5 Gbps SFP/RJ45 combo for flexible fibre or copper backhaul.
• Multi‑GbE service port:1 × 100/1000/2.5G/5GBASE‑T (auto MDI/MDIX) to separate service/IoT traffic or provide an additional wired path.
• Downlink/service:1 × 10/100/1000Base‑T downlink (PSE supply) for IoT devices or PoE power to an attached device.
• Console and USB:1 × RJ45 console port and 1 × USB 3.0 Type‑A for local management or USB‑based services.
• Power:Supports 802.3af/at/bt PoE and 54 V DC input for locations where PoE is unavailable.

Benefit: Dual 5 Gbps uplinks reduce the chance of a wired bottleneck in deployments where many APs aggregate large client traffic. SFP support enables fibre backhaul to IDFs or direct uplinks to core switches, while broad PoE support simplifies rollouts in buildings with mixed PoE capability.

• Recommended clients:Approximately 150 active devices per AP (environment dependent).
• Associations:Up to 1,024 client associations (environment dependent).
• BSSIDs:Up to 32 (up to 16 per radio) for flexible SSID and VLAN segmentation.
• Roaming:Enterprise-grade roaming with controller or cloud-assisted handoffs.
• Management:Ruijie Cloud, local controller, and fat/fit modes provide deployment flexibility.
• Security:WPA2/WPA3, 802.1X/RADIUS, guest portals and various authentication options.

Benefit: Whether you want centralized cloud management for multi-site visibility or a local controller for on-prem control, the RG-AP840-L supports both. High association limits and multiple BSSIDs make it suitable for segmented environments like universities and hotels.

• Dimensions & weight:230 × 230 × 51 mm, approx. 1.0 kg.
• Mounting:Ceiling or wall mount; Kensington lock supported.
• Operating temperature:−10°C to +50°C.
• Bluetooth:Bluetooth 5.1 for location-based services and IoT integration.
• Regulatory notes:Check official datasheet for RF tables, regional firmware and certifications (CE/UKCA or country-specific approvals).

Note: For final power budgets, channel planning and regulatory compliance, always consult the official Ruijie datasheet and verify local certification and firmware requirements prior to installation.

Use cases and scenarios where the RG-AP840-L excels

Lecture halls and campus buildings often have bursts of simultaneous connections as hundreds of students access streaming video, cloud services and collaborative tools. The RG-AP840-L’s combination of MU‑MIMO and OFDMA plus its AX5400 throughput capacity makes it well-suited to these environments. The high association ceiling and multiple BSSIDs help universities separate administrative, student and guest networks.

Hotels, conference centres and meeting rooms require stable Wi‑Fi for guests, staff and event services. Bluetooth 5.1 supports location analytics and proximity services; separate service ports can isolate payment or IPTV traffic. The compact build and flexible PoE/DC options simplify deployment in new properties or retrofits.

Office floors with dense laptop and mobile phone usage benefit from the RG-AP840-L’s multi-gig uplinks. Where a single gigabit uplink would become a bottleneck during heavy usage, the 5Gb combo and 5G RJ45 provide headroom and futureproofing for richer cloud applications and unified communications.

From libraries to municipal buildings, the ability to create segmented SSIDs, apply client limits, and manage guest portals makes the AP appropriate for public deployments where security and QoS are important.

How the RG-AP840-L compares with similar products

Within the enterprise Wi‑Fi 6 class, the RG-AP840-L competes with offerings from Aruba, Cisco and value-oriented vendors such as Ubiquiti. Several comparative points are worth noting:

• Uplink flexibility:The dual 5 Gbps options (SFP/RJ45 combo plus a 5G RJ45) set the RG-AP840-L apart from many APs that only provide single‑gig or single multi‑gig Ethernet. Competing APs from large vendors often offer multi‑gig ports but may lack simultaneous SFP and RJ45 flexibility in the same unit.
• Enterprise feature set:Aruba and Cisco platforms typically offer very mature enterprise features and deep controller ecosystems; Ruijie’s RGOS and cloud management provide comparable basic to advanced feature sets at a more affordable price point, though feature parity for very large, complex deployments may require evaluation.
• Price vs performance:At a suggested price of $399, the RG-AP840-L presents strong value against premium APs from Aruba/Cisco that can be significantly more expensive, while offering more enterprise features than many value-focused vendors. Ubiquiti and similar vendors may be cheaper but often trade off enterprise integrations, RADIUS/802.1X features, or multi-site cloud controls.
• Power requirements:Native support for 802.3bt helps environments with higher power needs; some older or lower-cost APs rely only on 802.3af/at and thus restrict feature use or require upgrade of PoE switches.

In short, the RG-AP840-L sits in the mid-to-high tier of enterprise APs: more capable and flexible than consumer/prosumer models, and more cost-competitive than some premium vendor alternatives, with the added advantage of multi-gig uplink options and comprehensive management choices.

These anonymized and paraphrased impressions reflect common themes: improved throughput in dense areas, appreciation for multi-gig uplinks, and positive responses to cloud-based management and security features. Exact experience will vary by site layout, RF environment and backend switching infrastructure.

Conclusion: why the RG-AP840-L is a strong choice

The Ruijie RG-AP840-L is a compelling option for organisations that need enterprise Wi‑Fi 6 performance without paying a premium for brand-name pricing. Its AX5400-class radios, OFDMA and MU‑MIMO support, and 160 MHz capability provide modern wireless efficiency and throughput. The standout multi‑gig uplink options — a 5 Gbps SFP/RJ45 combo and an additional 5G RJ45 port — give deployment flexibility and help avoid wired bottlenecks in high-traffic environments. Broad PoE support (802.3af/at/bt) and a DC input simplify installation across a wide range of buildings.

Management flexibility (Ruijie Cloud, local controller or fat/fit modes), enterprise-class security (WPA3, 802.1X/RADIUS) and support for Bluetooth services round out the feature set, making this AP suitable for universities, hotels, enterprise floors and public venues. At a suggested price of $399, it offers an attractive balance of capability and cost, especially for organisations looking to future‑proof their wireless fabric with multi‑gig backhaul and cloud management.

Before purchasing, confirm local regulatory firmware and certifications, plan site PoE and uplink architectures, and consult the official Ruijie datasheet for RF tables and deployment guidelines. With proper planning, the RG-AP840-L can be a high-impact building block in a robust, high-density enterprise Wi‑Fi deployment.
