What should be the real next-generation wireless network 5G?

It's hard to imagine a world in which smartphones are faster than we are now.

Now that you have been able to pick up your phone, ask Google questions and get an answer in seconds.

The next generation of wireless technology will become faster, but its main goal is not speed.

The next generation of wireless networks will solve one of the most troubling problems we have now: stable and fast network connections.

The main goal of 5G networks is to keep end users connected, whether they are indoors or outdoors, whether they are near the window or in the basement.

We need such powerful networking capabilities, in part because 5G networks will support more than just smartphones in the future – it also supports smart watches, fitness wristbands, and smart home devices such as the nest-type indoor thermostat.

What is a 5G network?

The 5G network refers to the next generation wireless network. In the past few years, we have seen various new trends since the promotion of 4G networks, including LTE, LTE Advanced and Verizon's XLTE.

All of these developments are based on the same core requirements and are attributed to 4G networks. However, the 5G network will be a truly upgraded version of the 4G network, and its basic requirements are different from today's wireless networks.

We need to understand the difference between these networks, because the performance of your phone will depend to a large extent on the network you are connected to. It is more than just a small symbol in the upper right corner of your phone.

The leap from 3G to 4G has made the high-speed download a qualitative improvement. On 3G networks, it's almost impossible to use services like Netflix. This is one of the reasons why 4G networks have been promoted in the past few years.

So what will the 5G network bring? What will we do with it? At this stage, it is difficult to answer this question. However, industry analysts have begun to make predictions.

Speed ​​is not the most important thing

This misunderstanding is widespread: 5G networks mean ultra-fast data transfer speeds. This is because the early tests we have seen so far emphasize that 5G networks are much faster than today's networks.

Last May, Samsung announced that its upcoming 5G technology can transmit more than 1G of data per second.

Relatively speaking, the relatively fast LTE network can transmit about 60M of data per second, which is equivalent to about 0.05G.

This wireless network will be much faster than any smartphone you experience. Google claims that even at 1G per second, you can download a full HD movie in less than two minutes.

Tod Sizer, vice president of wireless research at Bell Labs in Alcatel-Lucent, said the next-generation wireless network will definitely be faster than our current network, but this is not a key consideration for 5G networks.

"If you say that speed is something we need to improve on a 5G network, then you are wrong," Sezer said in an interview. "End users don't care much about speed. They care about what they use. What the application needs."

The biggest improvement we will see in 5G networks is its flexibility to support a wide range of devices. In addition to supporting mobile phones and tablets, 5G networks will also need to support wearable devices such as fitness trackers and smart watches, smart home devices such as nesting room thermostats.

“Supporting countless devices in a given area is what we design goals.” Sezer said, “We believe that in the future, everyone will need to have 10-100 devices to serve them.”

This is one of the reasons why we are so difficult to determine which technologies are needed for 5G networks. It's hard to figure out how much data capacity is needed to support all of these devices.

"It not only has to support more data, but also to support more usage," said Peter Jarich, vice president of consumer and infrastructure at market research firm Current Analysis. "This has become our real Challenge. We don't know the answer yet."

Stand Mini Fan, also called table desk stand Mini Fan. You can use it on a table or a desk and can be connected to a computer or a notebook to make your work or study more comfortable. The arm of the standing mini fan can be adjusted and the head can be turned to about 70 degree. With big power, but the mini fan is very quiet and cool, which will not influence your study or work or rest.

Strong wind and no noise: The Mini Handheld Fan uses a brushless DC motor to provide strong wind while quiet, energy-saving and stable operation. The maximum rotating speed of the fan is about 3520 rpm which is enough to keep you cool, works by accelerating airflow, low noise, giving you a cool and wonderful summer.
