A veteran Wi-Fi expert on the technology shifts that mattered most, the truth about wireless security, and advice for engineers starting out.

Wireless connectivity is evolving faster than ever, reshaping how people work, learn, and stay connected. But behind every generational leap from denser networks to stronger security are engineers who've watched the industry mature firsthand.

In this episode of HFCL Time Machine, Wi-Fi Technology Expert Mr. Rasika Nayanajith joins Nadeem Akhtar, SVP at HFCL, for a wide-ranging conversation on the evolution of Wi-Fi, the technologies driving modern wireless networks, and where the industry goes from here.

Main Questions Asked

• What has your journey in the Wi-Fi industry looked like, and how do events like this contribute to the ecosystem?
• What's the single biggest technological advancement in the last decade of Wi-Fi that's improved the end-user experience?
• How does Wi-Fi's security posture compare to cellular, given recent standards changes?
• What advice would you give young engineers starting out in this industry?

• Why specialized Wi-Fi events matter they bring developers, AP vendors, and implementers together to show the full product lifecycle in one place
• Why OFDMA in Wi-Fi 6 and Wi-Fi 7 is critical for high-density environments like India, even when the benefits aren't immediately obvious
• Why modern Wi-Fi secured with WPA3 and 802.1x is often more secure than wired networks that rely on physical access control
• Why hands-on experience matters more than a degree: building home labs, learning tools like Wireshark, and not being afraid to break things

Tune in for a grounded, experience-driven take on where Wi-Fi has been and where it's headed next.
