Poornakumar Mezhiselvam contributed to rdkcentral/rdk-wifi-hal and OneWifi by developing and stabilizing Wi-Fi networking features and build systems using C and makefile. He enabled Passpoint 6GHz roaming and radar-triggered non-DFS channel switching, improving regulatory compliance and roaming reliability. His work included targeted debugging tools, diagnostic logging, and build compatibility fixes, addressing both runtime and compile-time issues. By refining MAC filtering and resolving build failures through careful code maintenance, Poornakumar ensured smoother onboarding and greener CI pipelines. His technical approach demonstrated depth in embedded systems, driver development, and network programming, consistently delivering robust solutions to complex wireless networking challenges.
March 2026 monthly summary focused on rdk-wifi-hal delivered radar-triggered non-DFS channel switching to ensure the driver transitions to non-DFS channels upon radar detection. This enhances Wi-Fi reliability and regulatory compliance in 5 GHz operations where radar events occur.

August 2025 – OneWifi: Focused on stability and build reliability. The primary deliverable was a critical bug fix that resolves a build failure by removing an unnecessary enum value from wifi_event_subtype_t in wifi_events.c, with no impact to existing functionality. This work supports the 25Q3 sprint and aligns with RDKB-60618 (commit 31aafc8d3eb6ec67ab65c512528ffbf2c20d24f5; PR #503). Impact includes greener CI/build pipelines for the OneWifi component, reduced risk of regressions downstream, and smoother integration for upcoming features. Technologies/skills demonstrated: C code maintenance, enum refactoring, debugging build failures, Git version control, and cross-team coordination (PR/issue tracking).

April 2025 monthly summary for rdkcentral/OneWifi. Focused on stabilizing grey-list workflow and hotspot reliability. Delivered a targeted fix to prevent gateway failures by enabling the MAC filter by default on hotspot VAPs and configuring it in blacklist mode. This directly reduces onboarding errors and improves network reliability for end users. Impact: Reduced gateway failures when adding devices to the grey list; smoother hotspot onboarding; better system stability with minimal surface area for change. Commit traceability: Fix tracked under RDKB-58764; commits include ea26c23182d17cba2e034bf6e757b92815e79d93.
