Ensuring consistent performance across standards, bands, and device types.

Throughput performance is one of the most critical KPIs for Wi-Fi client devices, directly impacting end-user experience in real-world scenarios such as video conferencing, enterprise collaboration tools, large file transfers, and cloud applications. For Client Device OEMs, validating throughput across multiple client models ensures reliable performance before product release.

The Challenge

• • Wi-Fi client devices often show large throughput variance due to differences in chipset, drivers, RF design, and firmware.
  • Lab-reported peak PHY rates do not necessarily translate to actual TCP/UDP throughput.
  • Poor-performing clients not only impact individual user experience but also consume more airtime, degrading the performance of the entire network.

Why This Testing Matters

• • User experience: Streaming, video conferencing, and large file transfers are highly sensitive to throughput performance.
  • Network efficiency: Low-throughput clients consume more airtime, impacting other users.
  • OEM validation: Ensures firmware and hardware optimizations are effective before mass deployment.
  • Operator assurance: Helps ISPs and enterprises qualify devices for their networks with confidence.

WiCheck for Client DUT Performance Validation

‘’Helping OEMs deliver reliable, high-performing Wi-Fi client devices’’ 

Core Focus

• • Standards & bands readiness: Validate device performance across Wi-Fi 4/5/6/6E/7 on 2.4 / 5 / 6 GHz.
    
  • Throughput assurance: Benchmark real TCP/UDP throughput to align with user experience expectations.
    
  • Connectivity & roaming: Ensure fast association, authentication, and seamless roaming with WPA2/WPA3.
    
  • Resilience validation: Test device stability under latency, jitter, and packet loss conditions.

Key Capabilities

• • Comparative benchmarking: Side-by-side performance reports against competitor devices.
    
  • Optimization insights: Detailed logs and KPIs to fine-tune drivers, firmware, and RF design.
    
  • Automation & CI/CD: Continuous regression testing across builds for faster release cycles.
    
  • Operator & market readiness: Lab-validated performance results that accelerate certification and adoption.

• • Client A underperformed significantly (64 Mbps) compared to Clients B (336 Mbps) and C (389 Mbps).
  • This indicates a nearly 6× throughput gap between the lowest and highest performing clients under the same conditions.

Why it matters

• • Confident client selection for enterprise/ISP rollouts.
    
  • Early identification of underperforming devices.
    
  • Competitive differentiation for OEMs.
    
  • Improved end-user experience and reduced support costs.
