Key Enabling Technologies
Evolving from the 4G era, 5G has numerous new technologies to keep up with the ever-increasing data demands.
Few Key Technologies are Multi-Beam, Full Duplex, Massive MIMO, Small Cell mesh networks will certainly improve overall multiple access and latency requirements and higher modulation schemes like 4096 QAM will boost the throughput to multi-gigabit capacity.
Along with advances in adaptive AI for spectral efficiency, key RF technologies like CDMA will improve efficiency further. More decentralized internet schemes (as portrayed in Silicon Vallley) may start taking over but are very less likely in early 5G roll-out. But Peer to Peer networks may be a reality in 5.5/6G networks in most of the world.
Backhaul for 5G will probably be dominated by fiber in Asian countries where back haul data demands are huge.
- Modulation Scheme
- Small Cell Mesh Density
- Spectral Efficiency
Multi-Path Fading is one of the most difficult challenges to solve for 5G. This will thus really put high pressure on EVM specs. But with the help of advanced DSP algorithms and efficient core RF technology rollout. These challenges can be resolved.
Why custom MMICs for 5G?
Custom MMICs are generally better for mass deployment of systems. Just take an example of a 5G fixed wireless access to small cells.
Assuming one city has 1000 such small cells with a phased array of 64 elements. Each chain in digital beamforming consisting of 20 commercially of the shelf components costing 20$ each will result in a system cost of
20$*20*64*1000 = $25.6Million for some towns. To achieve market competency and with our core MMIC expertise, we can make these entire systems for 20$ in production volume. which will result in overall deployment cost to 20*64*1000=1.28 Million per city.
