  WiFi when to start to make people feel confused? WiFi has begun to turn to the 5GHz spectrum, but the arrival of LTE-U will make the situation even worse. HaLow, 802.11ad, 802.11ax, 802.11ay, WiGig, LPWAN and MU-MIMO and what is it? Why Intel, Peraso and Qualcomm are committed to the development of 802.11ad?

  Wi-Fi technology re innovation to bring faster and more secure Internet of things

  The main purpose of these new technologies is to improve the efficiency, coverage and energy consumption. This article will describe the changes of Wi-Fi, and their impact on the IT and the Internet of things.

  WiFi current trends

  IEEE802.11 series LAN standard is called WiFi. Recently, WiFi router has been upgraded to the latest 802.11ac standard by the 802.11n standard.

  In recent years, the market appeared on the use of WiFiDirect standard printers, cameras and smart home devices, peak data transfer rate is 250Mbps. The latest progress of WiFi router can choose 2.4GHz and 5GHz spectrum, the former is called “2G”, the latter is called “5g, 2G channel crowded, but the coverage is more than 5g, the coverage of small, but data transmission speed is faster.

  Therefore, in the case of distance from the router for the use of 2G, in the distance from the router closer to the use of the movie when downloading 5G. While providing 2G and 5G channel router abound, but there are many factors in the future of WiFi.

  What are AC5400, AC5300, MU-MIMO and 802.11ax?

  Several so-called ”tri band Gigabit“ 802.11acWiFi router in 2016 the market, despite their commitment to data transmission rate for 5300Mbps-5400Mbps -- so they has two informal name: AC5300 AC5400, they actually only ordinary dual band router increase the a 5GHz band.

  TechRadar said that the purpose of this innovation is to improve the convenience of existing technologies, rather than a new technology. Upcoming models include LinksysEA9500Max-Stream and ASUS RT-AC5300, these two models are included MU-MIMO - represents a multi user, multi input and multi output.

  In the modern family usually have a variety of equipment, they will compete for bandwidth, especially video streaming, MU-MIMO equal share of the bandwidth, is expected to will become the future of WiFi router default properties.

  What is even more exciting is the prospect of supporting the 802.11ax standard WiFi router. 802.11ax standard is currently being developed, plans to release in 2019, the data transmission rate can reach 10Gbps, still using the 5GHz band. Market research firm ABIResearch predicts that by 2021, 802.11ax will account for 57% of the sales of WiFi chipset. Therefore, 802.11ax will become the new standard WiFi router”.

  What are the 802.11ad and WiGig standards?

  These are the same technology. WirelessGigabit (wireless Gigabit) is the abbreviation of the high end WiFi, the use of the 60GHz without a license spectrum, through the 4 2.16GHz band to get the highest 7Gbps ultra high data transmission rate. Gigabit WiFi provided by the WiGig is very suitable for the 5G era - when the user can make a smart phone, upload Full HD and 4K video.

  Although manufacturers have been testing, and 5G contact means that the next few years will not come out WiGig. Pulian, network and elecom in 2016 international consumer electronics show show the wigig router, Peraso recently in 2016 Computex Taipei show the its first WiGigUSB equipment. WiGig access points, network adapters, tablet PCs, smart phones and laptops will eventually be listed for sale.

  ABIResearch estimates, by 2018, WiGig chip sales will be more than 600 million. Is developing in the WiGig is the 802.11ay enhancement standard, the work frequency spectrum is 60GHz, the data transmission rate can be as high as 20Gbps, but the data transmission distance is short.

  What is WiFiHaLow?

  Narrow band of Internet of things devices to promote the new WiFi and connection innovation. Although many smart home and industrial networking devices can use Bluetooth or WiFi, they require a higher data transmission capacity, further transmission distance. HaLow based on the IEEE802.11ah standard, using the 900MHz band, the data transmission distance farther, the energy consumption is not high.
