New OFDMA Feature for 802.11ax (WiFi 6) Routers


Higher Transmission Efficiency with OFDMA

OFDMA has been used in LTE for many years, and is now available in 802.11ax for multi-user mode.

With legacy OFDM, each frame is transmitted across the entire channel width. When the transmission rate is low, this causes more latency and jitters and lower the overall efficiency.

OFDMA splits a single frame into groups of subcarriers, and each subcarrier can be sent simultaneously. With multiple access mode, it allows multiple users to transmit at the same time thus improving efficiency and enhancing user experiences in high density environments.

802.11ax BSS Colouring


In traditional 802.11 Wi-Fi networks, access points are designed to wait and take turns if other signals of the same frequency are detected from adjacent access points. This sharing of a resource, in this case radio frequencies, is called a basic service set (BSS). 802.11ax adds Colouring to the BSS information being broadcast so that APs can use the same channel at the same time without having to take turns. This increases Wi-Fi efficiency, particularly in high density environments.

In the diagram here, AP1 and AP4 are using Channel 1 simultaneously, which normally means they would have to take turns if transmitting information at the same time. However, using BSS Colouring, the 2 APs can now transmit simultaneously without waiting.

An 802.11ax AP using BSS Colouring has the ability to change its BSS Colour if it detects another AP using the same BSS Colour on the same frequency.

Hardware Acceleration


Without sacrificing traffic control features such as QoS, Bandwidth Limit, WAN Budget, Traffic Graph and Data Flow Monitor, Hardware Acceleration enhances performance for:

  • NAT & routing connections
  • QoS
  • IPsec VPN

Hardware NAT & Routing

With Hardware Acceleration and Hardware QoS enabled, the router supports up to 8k NAT and routing connections, and firewall performance reaching 940Mbps on single WAN and 1.3Gbps combined performance on multi-WANs.


Hardware QoS

Application QoS allows prioritisation of applications and services on DrayTek routers to improve and enhance critical applications such as VoIP, conferencing and video streaming, etc. It also allow flexible bandwidth allocation to suit business requirements.

 


Hardware IPsec

While the Vigor2865 series already has improved IPsec performance over the previous Vigor2862 series, with Hardware Acceleration enabled, IPsec performance can now reach 800 Mbps. The first 16 tunnels are automatically accelerated on a first come first serve basis. If any drops out, a new tunnel will be put into the accelerator automatically to top off 16 accelerated tunnels.
