Ponto de acesso sem fios HPE Aruba Networking R7J38A 2,4 GHz 5 GHz 6 GHz

The HPE Aruba Networking R7J38A is a tri-band wireless access point that supports 2.4 GHz, 5 GHz and 6 GHz (Wi‑Fi 6E) operation to deliver higher capacity, wider channels and reduced interference. Designed for campus and enterprise indoor environments, this AP provides up to 7.8 Gbps aggregate data rates with 4x4 MU‑MIMO support, integrated Bluetooth Low Energy and Zigbee for IoT, and two configurable Smart Rate Ethernet ports for redundant connectivity and hitless failover.

Advantages

By adding the 6 GHz band, the Aruba 650 series APs significantly increase available spectrum—up to 1200 MHz—allowing more simultaneous clients and bandwidth for video and cloud applications. Patented ultra tri‑band filtering optimizes channel utilization across 2.4/5/6 GHz to reduce interference. The AP supports Wi‑Fi 6E features including OFDMA, MU‑MIMO, Enhanced Open and WPA3 for efficient and secure wireless operation. Dual configurable Ethernet ports (1/2.5/5 Gbps) and PoE support improve resilience and simplify deployment.

Suitable for

• High‑density campus and enterprise indoor deployments
• Environments with bandwidth‑intensive video and cloud applications

How to use

Mount the access point indoors in a central location to maximize coverage. Connect one or both Smart Rate Ethernet ports to your network switch or PoE injector to provide power and uplink connectivity. Use Aruba management tools or your preferred network controller to configure SSIDs, security settings (WPA3 or Enhanced Open), role‑based access policies and band steering rules. Enable BLE and Zigbee support if IoT device integration is required. Adjust channel planning or rely on the AP’s tri‑band filtering to optimize 6 GHz channel utilization and reduce interference.

Recommendations

For dense deployments and bandwidth‑heavy applications, enable the 6 GHz band (Wi‑Fi 6E) and configure band steering to move compatible clients to 5 GHz or 6 GHz. Use both Ethernet ports where available for redundancy or link aggregation and apply WPA3 for the strongest client encryption. Place APs to avoid physical obstructions and coordinate channel allocations across nearby APs to maximize throughput.
