5G PCB Board Manufacturing and Assembly – One Stop Service
The fifth generation mobile communication technology (English: 5th generation mobile networks or 5th generation wireless systems, referred to as 5th-Generation, 5G) is the latest generation of cellular mobile communication technology, which is an extension after 4G (LTE-A, WiMax), 3G ( UMTS, LTE) and 2G (GSM) systems. Such as 5G PCB board. The performance goals of 5G are high data rates, reduced latency, energy saving, cost reduction, increased system capacity, and large-scale device connectivity.
The first phase of the 5G specification in Release-15 is intended to accommodate early commercial deployments.
The second phase of Release-16 will be completed in April 2020 and will be submitted to the International Telecommunication Union (ITU) as a candidate for IMT-2020 technology. The ITU IMT-2020 specification calls for speeds up to 20 Gbit/s for wide channel bandwidth and high-capacity MIMO.
5G PCB board development requirements:
- The mobile Internet and the Internet of Things are the two driving forces for the development of mobile communications in the future.
Mobile communications will continue to develop rapidly.
New mobile services are constantly emerging.
User experience requirements are constantly increasing.
4G mobile communication technology cannot meet future business and user experience requirements.
Research on 5G mobile communication technology has been launched globally.
Key technical indicator requirements of China IMT-2020 (5G) promotion group.
Limited spectrum resources have always restricted the performance improvement of wireless communication systems.
Multiple frequency bands, multiple access methods, and small coverage radius bring challenges to network technology.
The deterioration of channels under high-speed mobile conditions and the development of high-frequency channels pose challenges to high-speed transmission technologies.
The development of new communication technologies and high-frequency bands poses challenges to semiconductor technology.
The increase in energy consumption brought by massive devices poses a challenge to the requirements of green communication.
The cell density and interference brought about by the increase of mobile devices restrict the growth of network capacity and the improvement of transmission rate.
5G network characteristics：
- The peak rate needs to reach the Gbit/s standard to meet the transmission of large amounts of data such as high-definition video and virtual reality.
The air interface delay level needs to be around 1ms to meet real-time applications such as automatic driving and telemedicine.
Super large network capacity, providing hundreds of billions of device connection capabilities to meet the Internet of Things communication.
Spectrum efficiency is 10 times higher than LTE.
With continuous wide-area coverage and high mobility, the user experience rate can reach 100Mbit/s.
Greatly improve traffic density and connection density.
The system is synergistic and the level of intelligence is improved. It is characterized by multi-user, multi-point, multi-antenna, multi-intake collaborative networking, and flexible automatic adjustment between networks.
The above is the key to distinguishing 5G from previous generations of mobile communications and is the result of mobile communication moving from technology-centric to user-centric.
Application areas: car networking and autonomous driving, surgery, smart grid, etc.
In the future, 5G’s leading development trend has two directions: higher capacity and wider frequency band, and smarter communication network.
5G mobile communication will lead more key technologies, such as DBA (Dynamic Bandwidth Allocation), time-sharing group call, communication frequency division multiplexing, etc., to enhance the user capacity of 5G mobile communication technology.
