Samsung says that multi-path transfer control protocol (MP-TCP) technology is one of the key priorities for the company, as it allows aggregation among independent networks using different technologies, such as Wi-Fi, Internet of Things, 3G, 4G, 5G and more, and it's already been commercialized in South Korea.
It's part of the range of solutions that Samsung plans to present at Mobile World Congress 2016 next week in hopes of addresses challenges that operators face.
Distinguished from other technologies like dual/multi connectivity, MP-TCP enables the merging of data streams from each independent network, including non-3GPP standard-based networks, at the Internet Protocol (IP) layer, making aggregation faster and simpler, according to Samsung.
Last June, Korean telecom firm KT teamed launched the first commercialized MP-TCP service. Known as GiGA LTE, the service which was first made available for Samsung Galaxy S6.
In addition to downloading over 15 times faster than traditional LTE, GiGA LTE also boasts upload speeds that outstrip tri-band broadband LTE-A--Korea's fastest existing service--ten times over by combining 3-Band Carrier Aggregation LTE and Wi-Fi. The vastly improved speeds, which averaged between 600-700 Mbps during KT's press conference to announce the technology, represents a competitive advantage for KT as the company and the rest of the industry prepare for escalating mobile data traffic and an eventual evolution to 5G network technology.
Samsung is also introducing its Smart Multi-Link for the first time, based on its Unified Core architecture. It's designed to support backward and forward compatibility, incorporating 2G to 5G technology in addition to embracing non-3GPP standard technologies. Using NFV and SDN, Smart Multi-Link "enables the transformation of distributive networks into one unified and flexible network," Samsung said.
Of course, Samsung also will be among those demonstrating its 5G chops at MWC, despite the fact the industry has yet to approve a standard. Samsung promises to show a latency of less than 1 millisecond and high-speed data gigabit throughput when it demonstrates millimeter wave (mmWave) technology. Samsung also has been a leader in the mmWave arena, and it will introduce the "world's first mobile handover test using the mmWave radio system and smartphone-integrated, multiple antenna modules in a small form factor," the press release promises.
For public safety, Samsung will demonstrate its live push-to-talk services with multiple handheld devices to show a typical emergency use case. Its demo will showcase evolved Multimedia Broadcast Multicast Services (eMBMS), which enables HD videos and images to be broadcast to multiple devices with minimized network resources. With a virtualized core solution, a single PS-LTE network can be configured and operated independently for each government agency, such as police and fire, while being controlled from a single point at a main control center.
