5G era, WiFi 6 late

  While high-profile 5G came to us, so many people feel that WiFi will be eliminated, the following will be 4G and WiFi 5 compare, discuss with you.
  
5G era, WiFi 6 late
  
Power
  
  our lives already can not do without the phone, the phone can not come up from time to time brushing no sense of security, but the rapid decline in power when the extent of the collapse of the heart is not different from volcanic eruptions, for longer play phone, we use the 4G or WiFi Internet access it?
  It is proved, the length of time the mobile Internet and transmit power, whereas the size of the transmission power is mainly determined by the distance between the device and the signal source. As we all know needs to 4G base station transmission signal, while the base station was built mostly in the open, if the phone receives a signal from the distant hilltop, the frequency normally transmitted in the mobile phone needs to 100mW to 200mW, we need to consume more power, bad signal case even more. WiFi signal is transmitted through a router, home, corporate office router installation, even if the farthest corner squatting transmit power than 100 square house, the phone is also about 50mW, less the amount of power consumed. It can be seen that the greater the distance, the greater the required transmit power, Mobile shorter time.

Life comparative data
  
speed
  
  is fast WiFi connection speed or faster 4G Internet speed?
  
5G era, WiFi 6 late
  
  The number of speed WiFi antenna main job is saying about the band and routers. Performance of the above figure can be seen that the WiFi protocol versions are not the same. Under ideal conditions, 802.11n, maximum download speeds of up to 600Mbps, but the reality is that the Internet speed is slower than 200Mbps. Mainly because of using a router to use only 2.4G frequency band and speed simultaneously connect a plurality of devices using assessed down to reach 10MB / s.
  
  Now the mainstream 4G LTE network (enhanced version of the LTE), using carrier aggregation, the theoretical peak speed up to 1000Mbps. But in fact due to the terrain, the number of other equipment reasons, the basic speed of less than 5Mbps.
  
Cost price
  
  Are authorized 3G / 4G / 5G band to use, pay for, and the construction of base stations is also costly. Even now, traffic has become increasingly low cost, or even unlimited data plan, but traffic use after more than 20GB, Internet rate will fall to 1Mbps, which means that when reached 1Gbs 5G transmission rate, when one day your network speed You will be able to drop 3G.
  
  WiFi uses unlicensed radio spectrum is, and use low output power device that allows radio signals remain in the room, so that each room was undisturbed use the same frequency band. Only the cost of broadband and a router.
  
Internet security
  
  safety survey data show that the country's 80,000 public WiFi spot checks in the 21% risk. *** use of public WiFi users to steal personal information, Internet users to steal information such funds are not uncommon. The domestic carriers 4G network uses a "point to point" connection technology, each user uses a separate data channel, and 4G internet required by SIM authentication, therefore 4G security than WiFi.
  
VS WiFi6 5G
  
  5G network, as the fifth generation of mobile communications technology. 4G network which is the theoretical bandwidth of times (theoretical downlink speed of 10Gb / s), as well as low latency and low power consumption characteristics. 5G technology there URLLC (low latency communications) and standard mMTC (Big Things) is not specified down, expected in 2020, ITU (International Telecommunication Union) will be a comprehensive standard throughout the base station through 5G and the three major domestic carriers basically completed.
  
  WiFi6 come is very low-key. October 3, 2018 WiFi Alliance will be incorporated into the regular army based 802.11ax standard WiFi, and officially changed its name to WiFi6. The first two generations of technology --802.11n and 802.11ac named WiFi4 and WiFi5.
  
  WiFi6 than WiFi5 faster network speed, the capacity is greater. Not only that, WiFi6 also added to the multi-user MIMO technology (MU-MIMO) capabilities, and orthogonal frequency division multiple access (OFDMA), so that multiple devices simultaneously serve WiFi6 greatly improved. Speed between the user equipment updates, WiFi6 popularity takes a long time, all equipment (routers, mobile phones, wireless LAN, etc.) will support WiFi6 agreement.
  
5G era, WiFi 6 late
  
  5G with WiFi 6 have their own advantages and indoor use outdoor use WiFi or mobile communication most people practice, evenly matched the two parties still have their own world, I believe in the future for a long period of time, the two will always go hand in hand relationship.
