Samsung Link Indoor Solutions

Late last year, Samsung launched the Full Suite of 5G Indoor Products aimed at improving 5G connectivity indoors. As we move to higher frequencies for 5G, especially mmWave, alternative solutions will definitely be required to provide higher data rates. 

As can be seen in the picture above, there are three different solutions for different scenarios. The brochure here and this website here provides details but I have highlighted the relevant information below:

Link Cell is a compact indoor small cell that offers robust, ubiquitous in-building 5G mmWave coverage to deliver the high bandwidth, low latency and fast throughput needs for these businesses and public venues. The indoor solution can connect a large number of indoor users to data applications where signals from the outside 5G mmWave networks are hard to reach, enhancing productivity and providing a premium business experience. For enterprises that require dedicated connectivity and additional security needs the Link Cell can also serve as the foundation for a 5G private network. By combining a private 5G Core with Link Cells, an enterprise can have a secure, ultra-reliable, high-speed, low-latency 5G network that can accelerate their automation and digitization efforts.

To meet indoor coverage demands, particularly where capacity expansion is required or anticipated in the near future, Samsung offers a 5G Active DAS (Distributed Antenna System) solution called the Link HubPro. This system is especially useful in large buildings with extensive IT infrastructure. The solution includes two main components: a Radio Hub and Indoor Radio, and supports more diverse spectrums including, low-band and mid-band. With this simple architecture, single Radio Hub will allow a mobile operator to connect multiple radios and making multiple radios work as a single cell to build wide 5G indoor coverage without interference. 

Samsung Link Hub acts as a radio to connecting passive antennas supporting both LTE and 5G. If a building already has an existing passive DAS system, service providers can easily upgrade their indoor network to provide 5G service and reuse legacy cabling to save both time and costs. The Link Hub will act as a bridge between the 5G baseband and antennas by converting data traffic to radio signals, and vice versa, making 5G data traffic possible. The Link Hub can be managed remotely by an operator’s network management system.

The video below explains the solution in detail:

Here is another video that explains the indoor small cell, Samsung Link Cell

As a final thing, it should be pointed out that Samsung’s Link Cell features the Qualcomm 5G RAN platform, which builds on the collaboration between Qualcomm Technologies, Inc. and Samsung.
