In today's world, people are becoming more and more addicted to upgrading their technology and products. So it is not surprising to see more and more articles calling for the use of the 5GHz radio band to replace the traditional 2.4GHz radio band. However, if you do not fully understand the situation, it is foolish to automatically jump to a higher frequency band. Often considered an outdated technology, it has the latest and greatest potential for escalation in the tech world. So, if you completely get rid of the reason why 2.4GHz is a past network and what drives behind 5GHz, it is worth considering why leaving the current network may be the best attack plan. Wireless technology explodes Nowadays, the application of wireless technology is growing. More and more objects and devices are connected to the Internet with built-in wireless communication networks. In fact, according to a Cisco survey, only 500 million mobile connections and devices will be added by 2015. As you may have guessed, industry analysts predict that this trend has not diminished. Gartner, an investigative firm, predicts that with the massive expansion of the Internet of Things, there will be nearly 21 billion connected devices in the market by 2020. In this context, a considerable number of families Wi-Fi 2.4GHz band. Many countries have established standard connection design teams. In spite of this reality, the 2.4GHz band is getting worse for some reasons. First, congestion and interference become easier as the number of devices connected to the Internet increases and as bandwidth becomes more and more consumed. You can compare this to a room, slowly getting crowded, the voice of the conversation getting louder and louder, and becoming so large that you simply can not hear either side of the conversation. 2.4GHz opponents also adopted the traditional "bigger is better" concept. Devices that require large amounts of data require more data streams, more social media, and more entertainment, so naturally people start to feel overly crowded with their wireless needs. In the same way that mobile operators roll out 2G technology and reserve 3G technology, both wireless consumers and businesses are presumably pushing the bigger thing out. Why 2.4GHz still work While these practical issues may make sense in some circumstances, it is important not to reject them in a holistic manner. Today's world of technology revolves around the ability to communicate globally, and the 2.4GHz band is the only one of the most widespread and standard bands, such as the Global Industrial, Scientific and Medical (ISM) band. This means that companies can deploy a technology strategy for nearly every country on the planet to ensure lower development costs and better hardware compatibility. The bottom line is different from the higher frequency signal, the work using the 2.4GHz band is ubiquitous. Because it is a free spectrum, technology providers can gain the tremendous advantage of building scale. SpeedGuide pointed out that wireless signals with higher frequencies have a shorter range. This means that networks in the 2.4 GHz band have more bandwidth and greater reach, and penetrate solid objects better than 5 GHz networks. However, it is important that they take advantage of a powerful technology that makes good use of the least crowded frequency band. If you are unsure of who supports the technical debate, there are three scenarios here, and using the 2.4GHz band may still be the right choice: · Global Deployment: Due to the popularity of 2.4GHz, companies can build a single kind of device and use it all over the world. Other technologies that use different frequencies must be constrained by complex hardware and regulatory requirements around the world. · Higher profit margins: With billions of connected devices in this world of IoT, many devices will play a subtle role. Not all of these devices are smartphones, smart watches or connected cars; they may be cornfields or air quality sensors in the countryside. The ability to effectively connect a device to the 2.4GHz band is an absolutely relevant equation. Greater capacity: other narrowband technologies in the ISM band have limited data transfer rates. With technology providers connecting thousands of devices (even millions), the 2.4GHz band can provide enough network capacity for a wide range of IoT applications. In some cases, the ratio of supported devices is largely dependent on the 2.4GHz band when compared to the 900MHz band in the 2.4GHz band. While the world today is pursuing bigger and faster technologies, and assuming greater is better, one must think about your actual needs and why the 2.4GHz band is considered obsolete. The 2.4GHz band, as a radio frequency band, provides free worldwide coverage and offers more bandwidth than the 5GHz band. So there are plenty of reasons to keep the 2.4GHz band, which is probably the most realistic option, but only if you know how to use it.
