In today's world, people are becoming more and more addicted to upgrading technology and products. Therefore, it is not surprising to see more and more articles calling for the replacement of the traditional 2.4 GHz radio band with a 5 GHz radio band. However, if you don't fully understand the situation, it is foolish to automatically jump to a higher frequency band.
Often considered â€œoutdatedâ€ technology, it has the advantage of the latest and greatest upgrade potential offered by the technology world. So, if you completely abandon the reason for the 2.4GHz to become the past network, and the reason behind the promotion of 5GHz, it is worth considering, why staying in the current network may be the best attack plan.
Explosive development of wireless technology
Today, the use of wireless technology is growing. More and more objects and devices are connected to the Internet and built-in wireless communication networks. In fact, according to Cisco's survey, 500 million mobile connections and devices were added in 2015 alone.
As you may have guessed, industry analysts expect that this trend has not diminished. Research firm Gartner predicts that with the massive expansion of the Internet of Things, there will be nearly 21 billion connected devices in the market in 2020.
In this context, quite a few families of Wi-Fi use the 2.4GHz band. Many countries have established standard connectivity design teams. Despite this reality, the 2.4GHz band is getting worse for some reasons.
First, as the number of connected Internet devices increases and bandwidth consumption increases, congestion and interference become easier. You can compare this to a room, slowly becoming more and more crowded, the voice of the conversation is getting louder and louder, and it becomes so big that you can't hear the conversation on either side.
The opponents of 2.4GHz also adopted the traditional concept of â€œbigger is betterâ€. Devices with large amounts of data require more data streams, more social media, and more entertainment, so naturally, people's demand for wireless begins to feel that their space is too crowded.
Mobile communication operators are launching 2G technology in the same way, and reserved 3G technology. Consumers and enterprises of wireless communication assume that the introduction of larger things is also the best.
Why 2.4GHz still works
Although these practical problems are meaningful in some cases, it is important that they cannot be completely negated. Today's technology world revolves around the ability to communicate globally, and the 2.4 GHz band is the only clear and most common standard band, such as the Global Industrial, Scientific, and Medical (ISM) band.
This means that companies can deploy a technology strategy for almost every country on the planet to ensure lower development costs and better hardware compatibility. The bottom line is different from the higher frequency signals, and the work in the 2.4 GHz band is ubiquitous. Because it is a free spectrum, technology vendors can gain huge advantages in terms of construction scale.
SpeedGuide points out that higher frequency wireless signals have a shorter range. This means that networks in the 2.4 GHz band have more bandwidth and coverage, and the performance of penetrating solid objects is better than that of 5 GHz networks. However, it is important that it utilizes a powerful technology that makes good use of the least crowded frequency band.
If you are not sure which side of the technical debate is supported, there are three cases 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 limited by complex hardware and regulations around the world.
Â· Higher profit margins: With billions of connected devices in the IoT world, many devices will play a subtle role. Such devices are not all smartphones, smart watches or connected cars; they may be in the middle of a corn field or a sensor for air quality monitoring in the countryside. The ability to effectively connect a device to the 2.4 GHz band is an absolutely critical correlation equation.
â€¢ Larger capacity: Other narrowband technology data rates in the ISM band are limited. As technology vendors connect thousands of devices (or even millions), the 2.4 GHz band provides enough network capacity for a wide range of IoT applications. In some cases, when comparing the 2.4 GHz band to the 900 MHz band, the proportion of supported devices is largely dependent on the 2.4 GHz band.
While the world today is pursuing bigger and faster technologies, and assuming that bigger is better, people must consider your actual needs and why the 2.4GHz band is outdated.
As a wireless band, the 2.4 GHz band provides free cost on a global scale and provides more bandwidth than the 5 GHz band. So there are many reasons to keep the 2.4GHz band, which is probably the most practical option, but only if you know how to use it.
What are the best batteries for solar? Batteries used in home energy storage typically are made with one of three chemical compositions: lead acid, lithium ion, and saltwater. In most cases, lithium ion batteries are the best option for a solar panel system, though other battery types can be more affordable.
If you install a solar battery today, you will likely need to replace it at least once to match the 25 to 30 year lifespan of your PV system. However, just as the lifespan of solar panels has increased significantly in the past decade, it is expected that solar batteries will follow suit as the market for energy storage solutions grows.
The most important ones to use during your evaluation are the battery`s capacity & power ratings, depth of discharge (DoD), round-trip efficiency, warranty, and manufacturer. Capacity is the total amount of electricity that a solar battery can store, measured in kilowatt-hours (kWh).
