SUDAS is an indoor mobile coverage solution delivering very reliable connectivity and high throughput that can be flexibly tailored to end user data rate needs.
A SUDAS infrastructure is based on many low-cost and low-power relay nodes distributed in an indoor environment (Shared UE-side Distributed Antenna Components, SUDACs). Those SUDACs are easy to deploy. They receive signals from different base stations and forward them in an mm-wave band (relaying). The signals can then be received by multiple user equipment (UEs) in a building or vehicle. Uplink communication follows the same path in reverse.
By combing massive MIMO (multiple input multiple output) and mm-wave communication SUDAS acts as a mobile signal booster that enhances in-building mobile coverage. It can play a significant role in the future 5G-Advanced and 6G indoor communications market by providing a generalized solution suitable for all indoor and even certain outdoor environments. In outdoor areas, SUDAS extends the coverage of mobile networks, enabling to fill coverage gaps without the need for installing additional base stations.
