Brightline Interactive LLC and a leader in spatial computing, deep tech and 5G integration, is powering and connecting its immersive technologies in collaboration with AT&T for an integrated technological demonstration at the I/ITSEC, the large training and simulation tradeshow in the United States. This will be the first instance where two fully rollable NOVA simulator domes (from Eight360) and an additional mixed reality (MR) user are connected via AT&T's 5G network, driving super-fast data throughput, leading to minimal delay in visual presentation, thereby enabling complex and realistic multi-user training in a fully immersive environment. AT&T has integrated a temporary 5G network inside of Brightline's immersive laboratory for application testing, staging, and metrics capture in preparation for the I/ITSEC tradeshow.
