5G Network Architecture
Governments and private industry are working together to develop 5th generation(5G) mobile communication systems by designing network architectures capable of delivering "enhanced Mobile Broadband” (eMBB), "Ultra Reliable Low Latency Communications” (URLLC) and "massive Machine Type Communications” (mMTC). While 4G systems use frequencies in the 700MHz to 3.5GHz range, 5G functions in higher frequency bands. 5G architecture employs macrocell base stations operating sub-6GHz bands (like 3.7 GHz and 4.5GHz) to cover wide areas in combination with smaller base stations running in the millimeter wave band to provide local coverage.
Massive MIMO Technology
4G base stations emit their radio waves in all directions while 5G base stations employ "Beamforming" technology which uses multi-element antennas to form sharply focused beams.
This architecture supports “Massive Multi-Input Multi-Output” (MIMO) which enables simultaneous communication with multiple devices and greatly expands network coverage capability.
5G Multilayer PCB Solutions
Because 5G uses higher frequencies, low transmission loss circuit board materials are required. Panasonic has created a suite of Multilayer Circuit Board Materials that enable high-speed, low transmission loss designs by combining innovative resin systems with low-roughness copper foil bonding technology.
Panasonic low-loss PCB materials also exhibit superior workability which supports the requirements of leading-edge super multi-element antennas. This is important because ‘Multilayering” enables highly efficient integrated modules in which the antenna and the RF chip are on the same board.
To support product development, Panasonic has developed a unique modelling technology that can be applied for PCB materials up to 110GHz.
Panasonic introduces an innovative test methodology for accurately characterizing PCB materials for high-speed communication system designs.
