It was the technology visionary Steve Jobs (1955–2011) who expanded the Danish philosopher Søren Kierkegaard’s (1813–1855) philosophical quote which originally said, “Life can only be understood backwards; but it must be lived forwards.” Steve applied this notion to technology saying, “You cannot connect the dots looking forward; you can only connect them looking backwards. So you have to trust that the dots will somehow connect in your future.”
Connecting in the Future
Well, the dots of our future are certainly going to be more connected. How they are connected requires backward thinking.
Fifth-Generation (5G) wireless technology is ensuring that mobile networks of our future will connect us all. One might say that our future is one of hyper-connectivity in which machines, computers, robots, and people will all interface together.
This article will take a quick glance at the transformational leap that innovative 5G technology is enabling towards superfast communications, and how Mouser’s key electronic component suppliers are supporting this effort. As engineers, it’s time to put on our thinking caps, turn them backwards, and look at how our wireless communication infrastructure requires higher performance in order to meet the needs of tomorrow.
The Race is On
Being the first to market presents exciting opportunities for businesses. Key network service providers, mobile phone manufacturers, and component manufacturers recognize the necessity to be involved early. Service providers, including Verizon and AT&T, have recently made announcements indicating that they are starting to support 5G services in select cities. In place are additional plans to continue the roll out to new cities on a regular basis every month. T-Mobile and Sprint will be following closely behind.
Mobile phone manufacturers, including Motorola and Samsung, are now offering hardware devices that are set to comply with coming 5G capabilities. Telecommunication equipment providers are adapting their products to meet the coming requirements. It will be prudent later to look at how electronic component manufacturers are addressing the changing competitive landscape.
One item requiring tremendous focus is the move from fixed wireless access to 5G mobile non-standalone (NSA) and 5G mobile standalone (SA). NSA will employ 5G mobile built upon a 4G Long-Term Evolution (LTE) core, while SA will receive support from the 5G specific core.
The Road Forward to 5G
5G is the natural evolution forward from the presently employed 4G technology. It offers the conceivable potential to handle and administrate three orders of magnitude (103 = 1,000x) more data and information than current technology. This not only represents wireless connections with evolutionary increases but an entirely new level of nearinstantaneous connectivity.
While 3G provided users with accessible mobile access to the World Wide Web, 4G has allowed users to be connected socially. However, 5G’s new level of connectivity will enable applications that change the way we live, work, and relax. It will bring forward the dynamic power of the Internet of Things (IoT). This technological revolution will revolve around the wireless infrastructure that will enable new applications such as autonomous vehicles that are capable of driving and navigating obstacles without issues. Industry will change by way of the Industrial Internet of Things (IIoT), in which robots and industrial automation will be taken to new levels. Work and leisure will change to the ability to employ exciting applications such as augmented reality (AR), mixed reality (MR), virtual reality (VR), and extended reality (XR).
A key to 5G is the group of standards already in place to ensure that this new infrastructure is secure, robust, and highly efficient. The 3rd Generation Partnership Project (3GPP™) organization works to guarantee the effectiveness of these standards. Technical Specification Groups (TSGs) within 3GPP work on issues related to Radio Access Networks (RANs), Service and System Aspects, and Core Network and Terminals (CT). 5G New Radio (NR) specifications are a development that rolled out in late 2017. 5G Phase 1 correlates with Release 15, which is currently in play. In parallel with Release 15, yet fully rolling out at a later date, is Release 16, which will bring into reality 5G Phase 2 (Figure 1).
Let’s now look at some of the specific technical ways that 5G will propel connections forward.
5G’s ultra-wideband capabilities will enhance mobile broadband. It will allow a massively larger amount of devices to connect to the Internet without issues, fueling a dynamic explosion in the IoT. Plans are in place to support a reality that has >1M (>106) devices per square kilometer (km2).
With much greater connection speeds, 5G potentially promises data rates of 1–10Gbps in contrast to current connection speeds of 50Mbps. Download speeds will also improve.
Latency, the time delay before a transfer of data begins, will be improved. Reliable, low-latency communications will drop to under 1ms, an improvement at least in an order of magnitude of >101 = >10. Because of low-latency, fast-moving, real-time devices, applications such as self-driving vehicles will have the capacity to locally process, decide, and respond with faster than human reflexes.
5G’s greater spectrum efficiency, through novel multiple-input and multiple-output (MIMO) antenna and associated technologies, will enable more bits of data to be transferred at specified frequencies.
5G’s powerful network processing and control will realize significant gains in its network power efficiencies, enabling more data transfers while lowering energy consumption per data bit transferred. It is expected, despite the high device density coupled with high data streams, that overall 5G network power will be lower than today. This lower power consumption will also extend battery life for devices in the field, ensuring that field replacement issues do not overwhelm users after initial installation.
Taken into mutual consideration, all these previously mentioned facts mean that the level of 5G data throughput will explode. High throughput requires high-level infrastructure support to keep things operating smoothly.
