KT announced that it has completed what it claims is the world’s first ‘5G lowlatency multi-radio access technology’ test in a 5G commercial network incollaboration with Tessares.
The 5G multi-radio access technology, which the 3GPP has named ATSSS (AccessTraffic Steering, Switch and Splitting), is one of the 5G differentiators that is standardized in the 3GPP Release-16 5G System Architecture Standard (3GPP TS23.501). ATSSS was defined in collaboration with KT, Apple, Deutsche Telekom, Orange, and Cisco and is based on Multi-Path TCP technology. KT is leading the development of multi-radio access technology, and applied it to commercialize the world’s first ‘GiGA LTE’ and ‘GiGA 5G’ services in 2015 and 2019, respectively.
ATSSS technology reduces the initial session setup time to achieve 5G ultra-lowlatency in a multi-radio context, resulting in a setup delay of less than half compared to previous approaches. KT and Tessares have together led the international standardization of this initial delay reduction technique through the IETF TCP Working Group. Founded by MPTCP experts, Tessares is a Belgian tech company providing software based hybrid Internet access bonding to telecom operators.

The success of this low latency multi-radio access technology test will allow customers to take advantage of existing LTE and Wi-Fi networks, as well as 5G, to enable wireless services at higher speed and quality.
Denis Periquet, CEO, Tessares
We are convinced that mobile Internet usage requires an efficient combination of all existing network assets such as WiFi, LTE and 5G. We are delighted to have collaborated with KT, who is clearly leading the 5G race, to demonstrate the benefits of ATSSS.
