For agricultural, inspection, and mapping drones, the weakest link in the field is rarely the flight controller — it’s the wireless link. Video dropouts, control-command latency, and interference between multiple concurrent aircraft all directly affect operational efficiency and, in some cases, flight safety. Picking the right wireless hardware platform ultimately comes down to trade-offs between throughput, range, integration approach, and deployment environment.
524WiFi and Wallys currently offer three Qualcomm WiFi 7-based platforms that map to different drone video/control link scenarios: DR5322, DR9574S, and DR5424. Here’s how they differ, and which one fits which use case.
DR5322: Lightweight and modular, built for cost-sensitive edge nodes
The DR5322 is built on Qualcomm’s IPQ5322 (quad-core Cortex-A53 @1.5GHz) and is essentially a compact routerboard: onboard 2×2 2.4GHz radio, with 5GHz/6GHz handled through an add-on QCN9274/QCN6274 WiFi 7 module, reaching up to roughly 5764Mbps physical data rate. It offers 4x 2.5G Ethernet ports plus 1x 10G SFP, with 802.3bt PoE support.
This “onboard 2.4G + pluggable high-band module” architecture makes the DR5322 well suited as a relay node or video-transmission hub for a single small multirotor — where the priority is small footprint, low power, and controlled cost rather than maximum throughput. Think field-deployable relay boxes or vehicle-mounted repeaters.
DR9574S: The modular flagship, built for relay towers and multi-drone coordination
The DR9574S runs on Qualcomm’s IPQ9574 (quad-core ARM-A73 @2.2GHz) and is the most configurable of the three — six version options (2×2/4×4, 5G/6G/5-7G) let you tailor the band mix to the project. It supports OFDMA, MU-MIMO, and multi-link operation (MLO), with 10G SFP, 10G Ethernet with PoE, and 2 Gigabit ports, plus optional GPS. Industrial-grade design supports operation from -20°C to 70°C.
This configuration is a better fit for fixed base stations, relay towers, or scenarios that need to manage video/control links for multiple drones at once — for example, a large-scale agricultural operation running several spraying drones simultaneously, where the ground station needs to reliably carry multiple concurrent video and control streams.
DR5424: High-throughput tri-band, built for aggregating high-definition multi-stream video
The DR5424 is the most integrated of the three: Qualcomm IPQ5424 (quad-core Cortex-A55 @1.8GHz), full onboard tri-band WiFi 7 (4×4 MU-MIMO), 320MHz channel width, with theoretical physical data rates up to 1376Mbps on 2.4GHz, 8647Mbps on 5GHz, and 11530Mbps on 6GHz. It also carries the strongest port configuration of the three: 4x 2.5G plus 2x 10G Ethernet.
One important clarification: DR5424’s tri-band design is switchable, not concurrent — the three bands are there to be switched between as needed to avoid interference, not to simultaneously carry separate traffic types (e.g., control on one band, video on another, backhaul on a third). This distinction matters when evaluating a project’s actual concurrent multi-video-stream capacity.
With onboard tri-band radios and multiple high-speed Ethernet ports, the DR5424 is well suited as an aggregation gateway for high-definition, multi-channel video feeds — for example, when several aerial video streams need to be backhauled simultaneously to a ground station for real-time stitching or AI-based analysis.

Which one should you choose?
- Budget-constrained projects that only need to support a single drone or a small number of video links — a lightweight relay node: go with DR5322.
- Larger operational radius, managing multiple drones online at once, needing a fixed base station or relay tower: go with DR9574S, selecting the version that matches your band requirements.
- Concurrent high-definition multi-stream video backhaul with high Ethernet aggregation bandwidth requirements, needing an edge gateway: go with DR5424.
All three platforms support OEM/ODM customization, including long-range transmission software tuning, antenna selection, and enclosure design.
