Aruba AP-735 vs AP-655: Mid-Tier Wi-Fi 7 vs Flagship Wi-Fi 6E

The HPE Aruba Networking AP-735 is a tri-radio 2x2 Wi-Fi 7 campus access point, while the AP-655 is the tri-radio 4x4 Wi-Fi 6E flagship from the prior generation. The interesting tension: the AP-735 brings the newer 802.11be standard with MLO and 320 MHz channels but fewer spatial streams, whereas the AP-655 keeps 4x4 MIMO and 5 GbE-capable uplinks. This guide compares both side by side so you can decide whether a cost-aware Wi-Fi 7 refresh or the proven 6E flagship is the right call for your campus wireless.

The short answer

For new builds and refreshes that want future-proofing, the AP-735 wins on standard: Wi-Fi 7 features like Multi-Link Operation, 320 MHz channels, and 4K-QAM extend the platform's useful life and improve performance for next-gen clients. The AP-655 still wins where raw spatial-stream capacity and 5 GbE uplinks matter most: very high client density on 4x4-capable devices today, or sites that already standardized on the 650 Series. If budgets are tight and you mostly serve 2x2 client devices, the mid-tier AP-735 is the smarter long-term buy; if you need maximum per-AP capacity for current 6E clients, the AP-655 holds its ground.

Where Aruba AP-735 wins

Wi-Fi 7 (802.11be) with MLO, 320 MHz channels, and 4K-QAM for higher throughput and lower latency
Newer standard means a longer support runway and better future-proofing for a refresh
Flexible dual-5 GHz / dual-6 GHz radio modes push aggregate capacity to ~14.4 Gbps
Dual Bluetooth 5.4 plus 802.15.4 (Zigbee) and dual USB for richer IoT integration
Mid-tier positioning makes Wi-Fi 7 affordable across more of the floor plan

Where Aruba AP-655 wins

4x4:4 MIMO on every band for more spatial streams and stronger per-AP capacity with 4x4 clients
Dual HPE Smart Rate ports support up to 5 GbE, easing wired-uplink bottlenecks
Higher 2.4 GHz peak rate (HE40) benefits legacy and IoT-heavy environments
Proven, widely deployed 650 Series platform with established AOS-10 feature support
Strong fit for sites already standardized on AP-655 for spares and consistency

Which one should you buy?

New campus build wanting the longest useful AP lifespan

Pick Aruba AP-735. Wi-Fi 7 with MLO and 320 MHz extends the platform's runway and benefits the next wave of client devices, justifying a forward-looking standard over capacity you may not use yet.

Very high-density area with many high-end 4x4 6E clients today

Pick Aruba AP-655. 4x4:4 radios provide more spatial streams to serve demanding current clients concurrently, and 5 GbE uplinks avoid wired bottlenecks under load.

Cost-aware refresh across a large floor plan with mixed 2x2 clients

Pick Aruba AP-735. Most laptops, phones, and tablets are 2x2, so the AP-735 captures Wi-Fi 7 gains where they matter while keeping per-AP cost in check across many radios.

Adding APs to a site already standardized on the 650 Series

Pick Aruba AP-655. Matching the installed base keeps RF design, spares, and AOS-10 configuration consistent, simplifying operations until a full Wi-Fi 7 cutover is planned.

IoT-rich deployment needing BLE, Zigbee, and USB peripherals

Pick Aruba AP-735. Dual Bluetooth 5.4 plus 802.15.4 radios and dual USB ports give more headroom for location services and connected-device gateways.

Frequently asked

What is the main difference between the Aruba AP-735 and AP-655?

The AP-735 is a Wi-Fi 7 (802.11be) access point with MLO, 320 MHz channels, and 4K-QAM but uses 2x2 radios, while the AP-655 is a Wi-Fi 6E (802.11ax) flagship with 4x4 radios and 5 GbE-capable uplinks. The AP-735 trades spatial streams for the newer standard.

Is the AP-735 faster than the AP-655?

On aggregate data rate, yes: the AP-735 reaches roughly 9.3 Gbps (and up to ~14.4 Gbps in flexible dual-radio modes) versus about 7.8 Gbps for the AP-655. But the AP-655's 4x4 radios can serve more spatial streams to capable clients at once, so real-world results depend on your client mix and channel widths.

Should I buy the Wi-Fi 7 AP-735 or stick with the Wi-Fi 6E AP-655?

Choose the AP-735 for new builds and refreshes where future-proofing and Wi-Fi 7 features matter, and most clients are 2x2. Choose the AP-655 when you need maximum 4x4 capacity for current 6E clients, want 5 GbE uplinks, or are extending a site already on the 650 Series.

Do the AP-735 and AP-655 use the same management platform?

Yes. Both are managed by HPE Aruba Networking Central and run under AOS-10, so they can coexist in the same environment and share a common operational model during a phased migration.

What PoE do the AP-735 and AP-655 require?

Both operate without restrictions on 802.3bt (Class 5) PoE. The AP-655 can also run full features on dual (combined) 802.3at, while the AP-735 will restrict certain functions like USB ports when powered by a single 802.3at source. Verify your switch's PoE budget when planning.

Does the AP-655 support Wi-Fi 7 features like MLO?

No. The AP-655 is a Wi-Fi 6E (802.11ax) access point and does not support Wi-Fi 7 features such as Multi-Link Operation, 320 MHz channels, or 4K-QAM. Those capabilities require the Wi-Fi 7 AP-735 or another 730 Series model.

Which AP is better for high-density environments?

It depends on the clients. For dense areas with many high-end 4x4 6E devices, the AP-655's extra spatial streams and 5 GbE uplinks help. For dense areas with mostly 2x2 clients, the AP-735 delivers Wi-Fi 7 efficiency gains while keeping cost per AP lower across the coverage area.
