now go out in the outside, nothing can, without WiFi, a restaurant and sat down the sentence is always "boss do you have a WiFi didn't", but someone said that the recent WiFi will soon become a thing of the past, gradually forgotten in the future.
operators launch unlimited packages
a few days ago, bloomberg said WiFi or will quit the historical stage, so that all major mobile operators because the United States to provide unlimited data traffic service, which means that people don't need to online connection WiFi to avoid costly traffic fee.
and the emergence of this package, a direct impact on the use of home broadband frequency, according to the authoritative survey, according to a survey released by about a third of people no longer use home broadband connection, because they have unlimited cell phone package.
in addition to foreign countries, domestic three carriers are also beginning to unlimited traffic layout, this also means that people on the Internet will be less and less cost.Recently released the news that this year October 1 phone ChangTuFei and roaming charges will be cancelled, this also means that the operators in the long distance and roaming the income will be discounted, and netizens the increasing traffic demand will become the focus of the operators are the wave of competition.
in fact, as early as last year, three carriers have been layout, in September last year, China unicom launched in jiangsu province unlimited card, the card can realize any flow in the province, the national 1 g flow, and free of charge 1800 minutes on the phone, in the province national no roaming, answer for free.The other two operators then also launched its own data.
telecom launched in Beijing area made CARDS, could enjoy 2 gb local 4 g network traffic, after more than 2 gb, local traffic can continue to use for free, but will speed limits, maximum speed is 3.1 MB (descending speed is about 384 k).
Beijing mobile launched its unlimited card, is higher than 1.5 G package flow, can enjoy free local traffic within the top speed of 128 KBPS.
science and technology changes with each passing day 3 big technology instead of WiFi
the greatest threat to WiFi network, should be the number 5 g network, according to industry insiders estimate that 2020 will be commercial in the global scope, 5 g 5 g is a what concept?There is 5 g speed can reach 10-100 times as much as 4 g, real-time transmission of 8 k resolution 3 d video, or downloading a 3 d movie in 6 seconds.
in addition to fast, 5 g network is more stable.Its client descending speed of the theoretical value of 20 GBPS, uplink speed can be up to 10 GBPS, per square kilometre can support 1 million access to the equipment.At the same time, 5 g network latency is reduced greatly, the highest do not exceed 4 ms, minimum 1 ms, only 20 ms far below 4 g networks.
what do you think only these 5 g?Of course not, but if 3 g, 4 g connection from person to person, you can connect everything in 5 g, it will infiltrate into areas such as the Internet of things, and industrial facilities, medical equipment, medical equipment, transportation, such as depth fusion, fully implement all interconnected, effectively meet the industrial, medical, transportation and other vertical industry informatization service needs.
this is a new system, it USES the unlicensed spectrum to increase the available for data communication network traffic, namely on the WiFi frequency deployment of LTE technical solutions.
popular speaking, it is to have the same effect and public WiFi hotspot, compared with the public wi-fi hotspots, LTE -u network faster and more convenient, the user can in the mobile cellular networks and LTE -u seamless switching on the network, but also in the process of switching from the frequent input password online trouble.
in addition, LTE -u to support the demand of equipment is also less., for example, a building 18 square feet (16700 square metres) of building, only need the 24 new access points.For the WiFi, you need to 80.At this point have to admit that WiFi is lost.
this is also the future may replace one of the new technology of WiFi, CBRS namely "Citizens of Broadband wireless business" (Citizens Broadband Radio Service).USES is the unauthorized 3.5 Ghz frequencies, this kind of band radar system currently used in the United States navy, the technology will allow anyone to share a large amount of spectrum resources currently used by the U.S. navy.
in August last year, Google, nokia and qualcomm has announced a joint for 3.5 Ghz network research cooperation, sharing using 3.5 Ghz spectrum private network just around the corner.
WiFi technology in the current new technology before violence for stability, security and other shortcomings, encouraged people to continuously explore the new domain, instead of WiFi black science and technology are born, but the real black from appearing to the wide application of science and technology still needs time, the imminent launch of WiFi historical stage, it is still too early, in recent years, at least, you go out to a restaurant, or want to ask, "how much" boss, your WiFi password.
