Researchers are growing indoor 5G routers with a number of antennas

Researchers in South Korea have developed a technology system that allows indoor and underground 5G networks to expand exponentially.

The The ETRI (Electronics and Telecommunications Research Institute) team essentially found a way to use this technology for indoor 5G networks that require high-speed internet, such as airports and virtual reality theaters.

Typically, 5G radio waves have difficulty reaching indoor and underground facilities as their access networks require much higher frequency bands. These shadow areas are known as gaps, Aju Business Daily reported.

The ETRI team decided to take matters into their own hands and the distributed antenna system (DAS). The DAS distributes 5G within buildings and bypasses all shadow gaps.

The aim is to connect and improve certain industries thanks to this new technology.

“We hope that this technology will help create an ecosystem of new convergent industries like interactive entertainment and smart factory and rejuvenate the stagnant domestic industrial ecosystem related to repeaters for mobile communications, while ensuring quality of service and eliminating the radio – Shadows Leave indoor areas, “said Sunmi Kim, director of ETRI’s network research division.

The technology includes multiple routers and antennas that are connected to each other thanks to optical cables. The router then forwards 5G signals received from a base station and then distributes them through the antenna on each floor of the building.

The DAS can split 5G signals 32 frequency bands that are able to send large amounts of data and offer 5G mobile data speeds of up to 20 GB per second. For context, this means you need to download a full HD movie just seconds.

The team’s optical DAS transceiver is roughly the size of a notebook and costs roughly 20% less than other similar devices. As Aju Business Daily noted, the DAS has already been commercialized in the United States, but no further details have been disclosed.
