Product Overview
The WLE900VX is a dual-band (2.4GHz or 5GHz) WiFi 5 (802.11ac) module built on Qualcomm’s QCA9880 “Peregrine” wireless solution. It packs 3T3R (3×3) MIMO and works across 2.4GHz or 5GHz bands, available in commercial-grade (QCA9880) and industrial-grade (QCA9890) variants. The module hits a standard 30×51mm footprint for painless hardware integration. With 3 spatial streams and 80MHz bandwidth available, you’re looking at up to 1.3Gbps throughput. High power, solid sensitivity, and wide temp operation make it a solid fit for industrial wireless, CPE, AP, bridge, and embedded device deployments.
On 5GHz, each chain pumps out 21dBm TX power; on 2.4GHz, it’s 20dBm per chain. For customers who need to swap bands on the fly based on their deployment, this thing’s got you covered. Works equally well as an AP or STA — handles backhaul while connecting end devices simultaneously. The 3.3V design keeps power draw low while maximizing range, outperforming Qualcomm’s reference design on efficiency. Ideal for power-conscious designs.

Frequently Asked Questions
What’s the difference between commercial-grade (QCA9880) and industrial-grade (QCA9890)?
The QCA9880 (commercial grade) handles -20°C to +70°C. The QCA9890 (industrial grade) extends that to -40°C to +85°C. If your deployment faces extreme temps, go industrial. Otherwise, the QCA9880 gets the job done at a lower price point.
Can this module run on platforms other than Qualcomm’s ecosystem?
Yes. WLE900VX works on third-party platforms including Intel x86, NXP, Marvell, and other ARM processors. It’s not locked into Qualcomm’s ecosystem — gives you flexibility in your hardware choices.
What’s the effective range for 5GHz operation?
In open field conditions, 5GHz links can exceed 300m. Obstacles, interference, and antenna selection affect real-world range. For long-range PtP links, use high-gain directional antennas (≥5dBi recommended).
Does it support DFS (Dynamic Frequency Selection)?
Yes. DFS support lets the module automatically switch channels when it detects radar interference — critical for compliance in many regions and for avoiding crowded frequencies.
What’s the typical power consumption in real deployments?
We measured ~4.8W in practice — slightly under the 5W spec. Power varies with TX power settings, traffic load, and temperature. Budget accordingly for always-on industrial deployments.
Is this module compatible with OpenWRT?
Yes. WLE900VX is compatible with OpenWRT, LEDE, and CompexWRT. Qualcomm’s ath10k driver handles the QCA9880, and community support is solid. Check the OpenWRT hardware database for specific target support.
What’s the warranty period?
Standard warranty is 12 months from shipment date. Extended warranty options are available — contact your distributor or reach out to us directly for details on coverage and support plans.
How do I get a sample for testing?
Contact our sales team directly. We support B2B inquiries and offer sample pricing for qualified projects. Lead time on samples is typically 1-2 weeks, depending on current inventory and your location.
