<p>Seoul, June 3, 2025 &mdash; The continued expansion of **5G networks across more than 100 countries** is rapidly reshaping how developers build and deploy web applications. With faster data speeds, ultra-low latency, and more reliable connectivity, developers are embracing new frameworks and features never before possible at scale.</p>

<p>According to a report from Ericsson, **over 75% of urban areas worldwide now have 5G coverage**, leading to a surge in the development of high-performance, media-rich web applications.</p>

<p>**Key Benefits for Developers:**</p>

<ul>
	<li>&nbsp;Real-time video and AR/VR content loading with reduced buffering</li>
	<li>&nbsp;Cloud rendering for web games and immersive experiences</li>
	<li>&nbsp;Improved WebRTC performance for video conferencing and live collaboration tools</li>
	<li>&nbsp;Faster mobile-first web app load times in regions with historically weak infrastructure</li>
</ul>

<p>**Industries Leading Adoption:**</p>

<ul>
	<li>&nbsp;**Education:** Live tutoring and e-learning platforms powered by browser-based AR</li>
	<li>&nbsp;**Retail:** Real-time 3D product visualization directly in mobile browsers</li>
	<li>&nbsp;**Healthcare:** Secure, low-latency telehealth platforms built using WebAssembly and React Native</li>
	<li>**Entertainment:** Web-based multiplayer games and streaming tools with integrated voice and video</li>
</ul>

<p>**Developer Community Response**</p>

<p>Chang Yoon, a senior developer in South Korea, said: &nbsp;<br />
*&quot;With 5G, we&rsquo;re building browser games that used to require native apps. It&rsquo;s the biggest leap in frontend performance since AJAX.&quot;*</p>

<p>Frameworks like **SvelteKit, Astro, and Remix** are gaining popularity due to their lightweight builds and 5G-ready SSR capabilities. Major CDNs like Cloudflare and Fastly are also upgrading their edge delivery networks to match the rising performance expectations.</p>

<p>**Global Education &amp; Training**</p>

<p>To help developers take advantage of 5G&rsquo;s potential, the W3C and Mozilla are launching a new online course series called **&ldquo;Web Speed in a 5G World&rdquo;**, featuring modules on mobile optimization, video streaming APIs, and real-time app design.</p>

<p>**What&rsquo;s Next?**</p>

<p>With satellite 5G coverage expected to roll out in rural Africa and Central Asia by 2026, experts believe web development will see a massive shift toward **global-first design** &mdash; where even remote users can access full app capabilities without downgrades.</p>
