The 5G network upgrade phase is set to bring significant changes to our daily lives. When we talk about 5G, we're not just thinking about faster internet—it's about a smarter, more connected world. Combining cloud intelligence with end intelligence can help meet the high demands of autonomous driving, which requires ultra-reliable and low-latency network connections.
Unlike previous upgrades from 2G to 4G, which were mainly about increasing data speeds, 5G represents a more comprehensive transformation. While earlier generations focused on improving speed—from voice to images to video—5G looks beyond that. It's about expanding coverage, enabling new applications, and meeting diverse user needs in a more intelligent way.
3GPP has defined three main application scenarios for 5G: eMBB (enhanced Mobile Broadband), mMTC (massive Machine Type Communication), and URLLC (Ultra-Reliable Low Latency Connection). These define the core capabilities that 5G aims to deliver across different use cases.
eMBB focuses on delivering higher bandwidth and better performance, aiming to support high-quality content like 4K/8K video, AR, and VR. This scenario was a major focus in the first release of 5G standards (R15), while mMTC and URLLC were developed later in R16.
One of the key challenges in 5G development is the coding scheme. In 2016, there was a big debate between LDPC and Polar codes. Eventually, LDPC was chosen for data channels, while Polar code was used for control signals. This decision was influenced by both technical merits and industry leadership, with Qualcomm playing a major role in shaping these standards.
According to ITU standards, 5G should achieve downlink peak rates of at least 20 Gbps and uplink speeds of 10 Gbps. For the 5% worst-case users, the minimum throughput should be 100 Mbps downstream and 50 Mbps upstream. This is a huge leap compared to 4G, opening the door for immersive experiences like AR and VR.
Qualcomm has been at the forefront of this evolution. Their Snapdragon X50 chip was one of the first to support 5G, and they’ve continued to push the boundaries with faster and more efficient solutions. With their strong baseband technology, they’re well-positioned to lead the next generation of mobile devices.
In the realm of AR and VR, Qualcomm’s position is even stronger. Companies like Oculus and HTC rely on Qualcomm chips for their latest headsets. With features like room-scale tracking, 6DoF, and SLAM, Qualcomm is setting the standard for immersive experiences.
Moving on to mMTC, or massive machine-type communication, this scenario focuses on connecting a massive number of devices efficiently. The goal is to reduce power consumption while increasing connectivity density. Though still evolving, it builds on existing technologies like NB-IoT and eMTC, making it an extension rather than a complete overhaul.
As 5G continues to develop, it will shape the future of connectivity, enabling smart cities, industrial automation, and more. The real value of 5G lies not just in speed, but in how it connects people, devices, and ideas in ways we've only begun to imagine.
