According to foreign media reports, whether it is a smart phone, thermostat or TV, almost every connected device has a Wi-Fi icon. But now, Wi-Fi is beginning to be forgotten.
With all the mainstream operators in the United States launching unlimited traffic packages, consumers no longer need to log in to the Wi-Fi network to avoid expensive traffic charges. This major change may prompt Wi-Fi to exit the historical arena, and the emergence of some competitive new technologies will make Wi-Fi's future look bleak.
“You may see a big shift,†said Tim Farr, founder of industry group Telecom Media Finance Associates. “Now, coffee shops may no longer need to provide Wi-Fi to their customers.â€
Farre expects that in a world of unlimited traffic, the proportion of mobile traffic used by consumers in public places such as stadiums and airports will drop from 1/2 to 1/3. This means that companies will no longer upgrade public Wi-Fi access, and mobile phone users may not even turn on Wi-Fi, said research firm Strategy AnalyTIcs Barry Gilbert.
"At the operator Sprint, the unlimited traffic plan is the norm, consumers will not wait until there is a Wi-Fi hotspot to start watching the video. They will always use traffic," said Moffett Nathanson analyst Craig Marford. “Consumers are rational. When price incentives are more prone to Wi-Fi, they will use Wi-Fi more. When price incentives change, consumer behavior will change.â€
The same is true at home. According to a survey released by ReportLinker on Thursday, about one-third of people no longer use home broadband connections because their phones have unlimited traffic packages.
Of course, the decline of Wi-Fi influence is likely to be a slow and rugged process. While wireless traffic services make Wi-Fi a dispensable thing for mobile phones, many home devices, from MacBooks to Amazon Echo speakers, still use Wi-Fi to connect to the Internet. In some office buildings and family homes with poor cell phone signals, Wi-Fi is still needed to fill the gap.
In addition, some operators will still need a Wi-Fi network to handle a large portion of the traffic demand. Today, streaming services such as Netflix and SpoTIfy have a huge demand for traffic, and relying entirely on cellular data networks will add to the burden.
Kevin Robinson, vice president of the industry organization Wi-Fi Alliance, said: "Wi-Fi has always been superior in terms of performance and ability to transmit large-scale data. The market will decide which technology will provide the best service to end users. Technology like Wi-Fi is likely to be too optimistic."
However, wireless data traffic is not the only threat to Wi-Fi. Wi-Fi has been around for 20 years, giving birth to a $20 billion market. But today, Wi-Fi is facing competition from other emerging technologies.
Crowded radio wavesFor example, a new system called "LTE-U" (LTE-U in Unlicensed Spectrum) uses unlicensed spectrum to increase available network traffic for cellular data communications and LTE's technical solution on the WI-FI band.
In the past few decades, US unlicensed radio waves have been used primarily for garage door switches, wireless handsets, and baby monitors. Now, unlicensed radio waves are also applied to Wi-Fi networks for connecting a range of smart devices such as mobile phones, laptops, set-top boxes, and game consoles. With the advent of LTE-U technology, Wi-Fi may be replaced by it.
“In areas where Wi-Fi has traditionally been used, operators will use LTE-U technology in the future,†said Mobile Experts researcher Kanyan Marne.
LTE-U technology is likely to be detrimental to companies that are primarily engaged in Wi-Fi calling, such as Comcast, and Google, which is obsessed with light networks.
But LTE-U will benefit users. Consumers will not need to enter a password or log in to each network. They can seamlessly switch between cellular data networks and LTE-U without noticeable differences.
There are also fewer devices required for LTE-U and related LTE-LAA technologies. According to Amit Jaen, vice president of hardware vendor SpiderCloud Wireless, a 180,000-square-foot building requires about 80 Wi-Fi hotspots. With LTE-U technology, only 24 hotspots are needed, although the deployment cost will be similar to Wi-Fi.
Independent wireless analyst Chetan Sama said: "LTE will enter thousands of households and enter the enterprise, and Wi-Fi will become a backward technology."
Citizen actionAnother technology that may make Wi-Fi face the elimination is CBRS, the CiTIzens Broadband Radio Service. This new system allows anyone to share the vast spectrum of resources currently used by the US Navy. In February of this year, Nokia, Alphabet and Qualcomm used these spectrum test LTE technology to broadcast a high-definition video of a rally in Las Vegas.
CBRS is more reliable than Wi-Fi and may eventually become a better choice for factories, airports and ports, said Michael Pitts, president of CBRS Alliance and Nokia executive. Members of the CBRS Alliance include operators AT&T, Chatter Communications and Comcast. It is reported that the first batch of CBRS equipment will be certified for use in the middle of this year.
The biggest threat to Wi-Fi is the popularity of 5G. 5G technology allows users to download a high-definition movie in less than a second. By using CBRS, mobile operators can deploy 5G technology faster and easier. Because they can use shared spectrum instead of obtaining spectrum grants through auctions or transactions.
Even now, Wi-Fi has gradually disappeared from people's lives.
“Before I had to look for Wi-Fi hotspots, it was very inconvenient for me,†said Alabama entrepreneur Michael Jimbro, who signed up for the Verizon wireless traffic package last month. "Now, I don't have to do this anymore." (Compile / Sailing)
Water-cooled capacitor is supercapacitor is a capacitor with a capacity of thousands of farads.According to the principle of capacitor, capacitance depends on the distance between the electrode and electrode surface area, in order to get such a large capacitance, as far as possible to narrow the distance between the super capacitor electrode, electrode surface area increased, therefore, through the theory of electric double layer and porous activated carbon electrode.
