AirWave

AirWave is a live, interactive broadcast platform where viewers join via QR, ask questions, share videos, and shape the story with real-time feedback, likes, and trending topics.

Inspiration

Traditional broadcasts are one-way and outdated viewers are reduced to passive consumers. We were inspired by the rise of live streaming and the need for real-time engagement. We envisioned AirWave as a tool to transform broadcasting into something interactive, community-driven, and mobile-friendly.

What it does

AirWave is an interactive broadcast platform where audiences can do more than just watch. They can join live sessions, ask questions, react, comment, and even contribute video replies all via a simple QR code connection from their mobile devices. Hosts can gauge sentiment with likes and trending topics, creating a truly dynamic two-way experience.

How we built it

AirWave was built as a web application using HTML, JavaScript, AJAX, PHP, and SQL. The front end handles real-time interactions with JavaScript and AJAX to keep the experience dynamic without constant page reloads. PHP powers the server-side logic, managing sessions, user submissions, and broadcast controls. We used SQL to store and retrieve user data, live comments, video links, and engagement metrics. The system was designed with simplicity and speed in mind, ensuring smooth communication between viewers and hosts, especially during high-traffic live sessions.

Challenges we ran into

Real-time communication and video handling introduced latency issues and sync delays. Creating a seamless experience across web and mobile while handling different formats and bandwidths was technically demanding. Additionally, building an intuitive UI that encouraged interaction without overwhelming users took multiple iterations.

Accomplishments that we're proud of

Built a fully functional prototype that allows seamless mobile video input via QR scan Enabled live audience engagement with real-time question/feedback systems Created a flexible backend that scales for multiple simultaneous contributors Designed a clean, modern interface that resonates with both hosts and audiences

What we learned

We learned a lot about real-time communication, mobile-web interoperability, and how users behave in live engagement contexts. Also, we gained insights into simplifying tech-heavy solutions into user-friendly experiences without sacrificing power or flexibility.

What's next for AirWave

We plan to add AI-driven moderation, better analytics for hosts, and native mobile apps. We’re also exploring partnerships with media outlets and event organizers to integrate AirWave into live news, panels, and interactive storytelling formats.
