5G technology impacts everyone, that’s why it’s critical for non engineers to also have a basic understanding of what 5G is and what it can accomplish.
As carriers roll out their more advanced standalone (SA) 5G technology across the U.S., it’s important to understand that the development of the 5G NR (5G New Radio) was the key to enabling the 5G mobile communications system to work.
5G NR was developed from scratch by the standard’s organization 3GPP by taking the requirements and looking at the best technologies and techniques that would be available when 5G began to be deployed.
5G NR utilizes modulation, waveforms and access technologies that enable the system to meet the needs of high data rate services, those needing low latency and those needing small data rates and long battery lifetimes amongst others.
3PGG’s Release 15 document guideline has been especially trenchant. Release 15, with its many important new advances, includes the full definition of the 5G NR (New Radio) standard, which forms the foundation of 5G service.
The cornerstones to the new radio used for 5G are many, including optimized OFDM (Orthogonal Frequency Division Multiplexing). Early on, 3GPP decided to use a form of OFDM as the waveform for phase one of the 5G New Radio. It had been very successfully used with 4G, the more recent Wi-Fi standards and many other systems and came out as the optimum type of waveform for the variety of different applications for 5G. With the additional processing power available for 5G, various forms of optimization can be applied.
The specific version of OFDM used in 5G NR downlink is cyclic prefix OFDM, CP-OFDM and it is the same waveform LTE adopted for the downlink signal.
MIMO (multiple input multiple output) has been another cornerstone of 5G as specified by the 5G NR standards. MIMO has been employed in many wireless systems from Wi-Fi to the 4G cellular system. Now as a mainstay technology within 5G, MIMO provides some significant improvements.
When built-out, 5G will deliver a wide range of new services, applications, devices and enhanced mobile experience such as Enhanced Mobile Broadband (eMBB), Ultra-reliable and Low-latency Communications (uRLLC), and Massive Machine Type Communications (mMTC).
5G will also meet the demand for an increasingly digital lifestyle, and focus on services that have high requirements for bandwidth, such as high definition (HD) videos, virtual reality (VR), and augmented reality (AR), digital industry and latency-sensitive services.
Companies that haven’t prepared their staff and stakeholders for the 5G revolution will be playing catch up for a very long time.
The market for 5G semiconductors alone will boom to nearly $19 billion by 2022 according to a Bank of America report.
