Summary
Mobile service providers are expecting a huge increase in traffic in the near future. Capacity is the most pressing problem that mobile service providers will be facing. Researchers are already developing 5G technology to solve this problem. The conventional solution to increase the capacity is to build new towers, add more spectrum and to bring small cells. But these solutions are not very efficient but costly.
A California based startup Blue Danube Systems has proposed a high definition antennae system that uses 3D beam-forming technology to address this problem. . The transmitter and the receiver communicate through a "beam" in this method, so that the tower can form beams exactly where there is traffic. They use a Very Large Scale Integration (VSLI) based technology to design their technique.
Although this beam forming technology is currently used, they use a digital approach that needs complex algorithm. Blue Danube uses a mixed signal, Application Specific Integrated Circuit (ASIC) to achieve this using analog technology. This can be implemented in current LTE systems with minimal changes.
Relation
• Bandwidth is a scarce resource in any kind of transmission
• Mobile communication has an increasing demand
• VSLI technology as a method to complex electronic designs
• Importance of being able to designing ICs that are application specific instead of using commercially available ICs as they can be either an overkill or insufficient.
Message
Beam forming technology is a promising solution to overcome capacity problems in mobile telecommunication. It is achieved through Application Specific Integrated Circuit design.
