In recent years, the voice of 5G has grown stronger and stronger, promising to usher in a new era in car networking and personal communication. With the decline in tariffs, 5G is beginning to put pressure on WiFi, which has been popular in recent years due to free data offers. As a result, some people are starting to question the relevance of WiFi, thinking it might be becoming obsolete.
While 4G and 5G cellular networks have made great strides, they still face challenges in certain scenarios, especially when it comes to data usage. For individual users, mobile communication technologies like 4G and 5G are powerful, but not always perfect. Here are some issues:
1. Devices without a SIM card module, such as laptops or other peripherals, can't easily access cellular networks.
2. Even though SIM card plans are relatively cheap, the cost of wireless technologies like WiFi is almost negligible.
3. Data usage is often metered and charged, which can be a concern for heavy users.
4. Cellular networks lack the data analysis capabilities that WiFi networks offer.
5. WiFi supports additional technologies like Bluetooth and has taken a leading role in smart home ecosystems.
6. There are many other limitations and challenges.
Therefore, it's important to look at this issue with a balanced perspective. Five years ago, many believed that 4G would replace WiFi. Instead, the rise of 4G actually increased demand for local area networking. In fact, 4G helped boost WiFi’s popularity.
China Mobile has been pushing the transition from 4G to WiFi, and it’s proving to be a smart move. Recently, China Mobile released its third-quarter financial report, showing a slight increase in revenue. Notably, their broadband subscriber base has grown rapidly, surpassing 100 million users. This expansion highlights how WiFi has become an essential part of the home market, where traditional SIM-based networks fall short.
In the 5G era, the concept of "operators" may change. A recent article titled “After 5G, there is no 'operator'†sparked interesting discussions. Industry experts, like Wei Pei from the China WiFi Industry Alliance, believe that WiFi, originally tied to broadband, can now offer differentiated value. The more operators promote 4G/5G traffic, the more valuable WiFi becomes, even if coverage initially decreases.
What's next? It's possible that WiFi will evolve from WLAN to WMAN or WWAN, eventually becoming a Wi-Fi HyperNet. In this network, every user contributes by adding their own nodes, creating a temporary, shared infrastructure. Users won’t pay for connectivity but only for the services they use.
To support this vision, Jujiu Technology launched the BigWiFi platform—a new hardware and software solution that empowers city operators to become traffic leaders. They are currently recruiting national urban partners. As 5G continues to develop, WiFi is expected to play a key role in new media, the Internet of Things, and big data.
