• Ideal for mid-density to high-density environments like offices, campuses, and retail spaces

The AP515 represents a step up in both technology and network capability, designed to handle modern IoT devices and Wi-Fi 6 clients.

3. Wi-Fi Generations Explained

Wi-Fi 5 (802.11ac) – AP315

Wi-Fi 5, also known as 802.11ac, marked a major improvement over previous standards by introducing broader channel widths and MU-MIMO for better throughput and client management.

However:

✔ It doesn’t support OFDMA (Orthogonal Frequency Division Multiple Access).
✔ Client efficiency in crowded environments is limited.
✔ Maximum real-world performance depends heavily on client capabilities.

Wi-Fi 6 (802.11ax) – AP515

Wi-Fi 6 is the current mainstream high-performance standard:

✔ Supports OFDMA → divides channels into multiple resource units
✔ Enhanced uplink/downlink MU-MIMO
✔ Target Wake Time (TWT) for enhanced battery life in IoT devices
✔ 1024-QAM for improved spectral efficiency
✔ Better performance in dense client environments

Result: AP515 can deliver significantly better network performance in both speed and user experience — especially when many devices are active simultaneously.

4. Technical Specifications Comparison

Here’s how both APs stack up technically:

Wi-Fi Technology

5. Performance & Throughput

AP315 Performance

Because the AP315 uses Wi-Fi 5:

✔ Good for devices that don’t support Wi-Fi 6
✔ MU-MIMO helps with multiple simultaneous streams

However:

❌ Throughput cannot match modern Wi-Fi 6 APs
❌ Less efficient handling of dense client environments arubanetworks.com

AP515 Performance

The AP515’s Wi-Fi 6 design delivers:

✔ Better spectral efficiency → more usable throughput per client
✔ Faster aggregate speeds (~5.4 Gbps combined)
✔ More intelligent client distribution via Aruba ClientMatch
✔ Better handling of mixed client device populations

These capabilities translate to significantly better network performance, especially in enterprise and dense environments.

6. Features & Capabilities

ClientMatch Technology

Both models support Aruba’s ClientMatch feature, which intelligently steers client devices to the best radio and AP — optimizing performance and reducing user interference.

• In AP315, this is within the limitations of Wi-Fi 5

• In AP515, ClientMatch benefits from Wi-Fi 6’s enhanced telemetry and efficiency

IoT & BLE Support

Both APs include integrated BLE radios, but the AP515 goes further with Bluetooth 5 and Zigbee support — enabling broader IoT and asset tracking use cases without additional infrastructure.

Security Features

Modern enterprise APs require robust security.
Both AP315 and AP515 can support advanced security measures:

✔ WPA3
✔ Enhanced Open
✔ Enterprise authentication
✔ Centralized policy enforcement (when deployed with controllers)

However, because Wi-Fi 6 includes advanced encryption features optimized for modern traffic, AP515 has a slight advantage in efficiency with secure connections.

7. Deployment & Management

Controller vs Instant Modes

Both devices can be deployed:

✔ In a controller-based system (centralized management)
✔ In Instant mode (controllerless) — useful for smaller deployments

Density & Client Counts

Because of Wi-Fi 6’s improved architecture:

✔ AP515 supports more simultaneous active clients — making it a better choice for offices, retail, campuses, and hotels. arubanetworks.com
✔ AP315 is suitable for small-to-medium deployments with fewer devices.

8. Practical Use Cases

When to Choose AP315

Best fit if:

✔ Budget constraints exist
✔ Deployment is small — like local offices or branch sites
✔ Mostly Wi-Fi 5 devices are used
✔ Lower throughput and capacity needs

Note: AP315 may become outdated quickly as more clients migrate to Wi-Fi 6.

When to Choose AP515

Ideal for:

✔ Modern enterprises with Wi-Fi 6 client devices
✔ Environments with many users/devices
✔ IoT use cases involving BLE or Zigbee
✔ Future-proofed deployments

AP515 is future-ready and generally delivers better long-term value.

9. Pros & Cons Summary

AP315 (Wi-Fi 5)

Pros
✔ Mature, proven technology
✔ Lower cost
✔ Simple deployment

Cons
❌ Limited throughput vs Wi-Fi 6
❌ Not optimized for high client density
❌ Older Wi-Fi standard

AP515 (Wi-Fi 6)
