 With the anticipated surge in mobile traffic and 5G subscriptions, mobile operators must meet rising consumer and enterprise demand: high-data-rate video streaming, VR/AR, and immersive media. This increased need for indoor coverage cannot be addressed by traditional indoor systems or by outdoor radio deployments since modern building materials can block outdoor radio signals.
Ericsson is meeting this challenge by introducing the so-called 5G Radio Dot, a small-cell radio solution designed to satisfy the advanced indoor mobile broadband performance requirements demanded by 5G. The 5G Radio Dot is a natural evolution of the previous generation of the Ericsson Radio Dot System.
Compared to other indoor solutions, it takes less than half the time to install the system and it is able to support the new 5G midbands (3–6 GHz) with speeds of up to 2 Gb/s.
Operators will be able to deploy the 5G Radio Dot next to 4G solutions using the same cabling infrastructure, the same network architecture, and dot locations. This innovative smal-cell solution, which provides a simple upgrade path for existing radio dot system deployments by adding 5G technology capabilities, enables frequency, capacity, and technologies to be added seamlessly.
The radio dot system has been successfully deployed for many indoor applications used in large areas, e.g., office buildings, shopping malls, hospitals, and airports. Over time, the small-cell solution will also support 5G industrial applications ranging from connected factories to more extreme cases, such as connected mining.
The collaboration of Ericsson and Boliden shows how radio dot technology can improve safety and efficiency through the remote control of machines that keep people out of the most dangerous areas of the mine at the most dangerous times.
The 5G Radio Dot will undergo trials in late 2018 and will be commercially available in 2019.
