In recent years, the voice of 5G has become stronger and stronger, signaling a new era in car networking and personal communications. With the decline in tariffs, 5G is expected to create significant "public opinion pressure" on WiFi, which has been popular in recent years due to free data offers. As a result, WiFi may seem less relevant or even obsolete.
While 4G and 5G cellular networks are powerful, they still face limitations when it comes to specific scenarios and data usage. For individual users, mobile communication technology is undoubtedly the king of connectivity, but it's not without its shortcomings. Here are some key issues:
1. Devices without a SIM card module, such as laptops, cannot take full advantage of cellular networks.
2. Even though the cost of SIM-based data plans is low, wireless technologies like WiFi come at almost no cost.
3. For consumers, data usage is often metered and charged.
4. Cellular networks lack data analysis capabilities, whereas WiFi does offer this functionality.
5. WiFi has enabled technologies like Bluetooth and has taken a leading role in smart home ecosystems.
6. There are other limitations as well.
Therefore, it's important to approach this issue with a balanced perspective. Five years ago, many believed that 4G would replace WiFi. However, the opposite happened—4G actually boosted the demand for local area networking, helping WiFi gain widespread popularity.
China Mobile has been actively promoting the shift from 4G to WiFi, and this strategy has led to remarkable growth. Recently, China Mobile released its third-quarter financial report, showing a slight increase in revenue. Notably, the number of cable broadband subscribers has surged, surpassing 100 million. This move reflects a smart strategy by China Mobile to leverage WiFi and compete more effectively against China Telecom.
In the 5G era, the concept of operators may evolve. An article titled "After 5G, there is no 'operator'" caught our attention. According to Wei Pei Chuang from the China WiFi Industry Alliance, WiFi has the potential for differentiated operations, especially when combined with 4G/5G traffic. The more operators promote mobile data, the more value WiFi can generate. Although initial coverage might decrease, the revenue from Wi-Fi traffic will likely increase.
What’s next? It’s bold to predict that WiFi could evolve from WLAN to WMAN/WWAN, eventually becoming a Wi-Fi HyperNet. In this network, every user becomes a contributor, able to add their own node resources at any time. When activated, users won’t pay for the connection itself, only for the services they use.
To support this vision, Jujiu Technology launched BigWiFi, a new hardware and software solution that empowers city operators to become traffic leaders. Currently, national urban partners are being recruited. As 5G continues to develop, WiFi is set to play a crucial role in new media, the Internet of Things, and big data.
