Our company Shenzhen HUANET Technology CO., Ltd brings the WIFI6 XG-PON Optical Network Terminal(HGU) designed for FTTH scenario to the market. It supports L3 function to help subscriber construct intelligent home network. It provides subscribers rich, colorful,
individualized, convenient and comfortable services including voice(VoIP), video (IPTV) and high speed internet access.
WIFI 6 (formerly IEEE 802.11.ax), the sixth generation of wireless networking technology, is the name of the WIFI standard. It is a wireless LAN technology created by the WIFI Alliance based on the IEEE 802.11 standard. WIFI 6 will allow communication with up to eight devices at a maximum rate of 9.6Gbps.
Development history
On September 16, 2019, the WIFI Alliance announced the launch of the WIFI 6 Certification program, which aims to bring devices using next-generation 802.11ax WIFI wireless communication technology to established standards. WIFI 6 is expected to be approved by the IEEE (Institute of Electrical and Electronics Engineers) in late fall 2019. [3]
In January 2022, the WIFI Alliance announced the WIFI 6 Release 2 standard. [13]
The WIFI 6 Release 2 standard improves uplink and power management across all supported frequency bands (2.4GHz, 5GHz, and 6GHz) for routers and devices in the home and workplace, as well as smart home IoT devices.
Functional characteristics
WIFI 6 mainly uses OFDMA, MU-MIMO and other technologies, MU-MIMO (multi-user multiple in multiple out) technology allows routers to communicate with multiple devices at the same time, rather than in turn. MU-MIMO allows routers to communicate with four devices at a time, and WIFI 6 will allow communication with up to eight devices. WIFI 6 also makes use of other technologies such as OFDMA (orthogonal frequency division multiple Access) and transmit beamforming, which work to increase efficiency and network capacity, respectively. WIFI 6 has a maximum speed of 9.6Gbps. [1]
A new technology in WIFI 6 allows devices to plan communication with the router, reducing the time needed to keep the antenna energized to transmit and search for signals, which means less battery consumption and improved battery life performance.
For WIFI 6 devices to be certified by the WIFI Alliance, they must use WPA3, so once the certification program is launched, most WIFI 6 devices will have stronger security. [1]
Application scenario
1. Carry 4K/8K/VR and other large broadband video
WIFI 6 technology supports the coexistence of 2.4G and 5G frequency bands, among which 5G frequency band supports 160MHz bandwidth and the maximum access rate can reach 9.6Gbps. 5G frequency band has relatively less interference and is more suitable for transmitting video services. Meanwhile, it reduces interference and reduces packet loss rate through BSS color technology, MIMO technology, dynamic CCA and other technologies. Bring a better video experience.
2. Carry low-latency services such as online games
The online game business is a strong interactive business, which puts forward higher requirements in terms of broadband and delay. For VR games, the best access method is WIFI wireless mode. The channel slicing technology of WIFI 6 provides a dedicated channel for games to reduce delay and meet the requirements of game services, especially cloud VR game services, for low-delay transmission quality.
3. Smart home intelligent interconnection
Smart home intelligent Internet is an important factor in smart home, smart security and other business scenarios, the current home Internet technology has different limitations, WIFI 6 technology will bring smart home Internet technology unified opportunity, high density, large number of access, low power optimization integration together, and at the same time can be compatible with various mobile terminals commonly used by users. Provides good interoperability.
4. Industry applications
As a new generation of high-speed, multi-user, high-efficiency WIFI technology, WIFI 6 has a wide range of application prospects in industrial fields, such as industrial parks, office buildings, shopping malls, hospitals, airports, factories.
