Understanding the Differences: Non-Standalone vs. Standalone 5G Networks

There are two types of 5G network infrastructure: non-standalone (NSA) infrastructures that still rely on some 4G LTE equipment, and standalone 5G infrastructures that have their own cloud-native network core connecting to 5G New Radio (NR) technologies. The NSA strategy leverages a combination of 5G Radio Access Network (RAN), 5G NR interface, and existing LTE infrastructure and core network to give a 5G-like experience until network carriers are able to build out the independent infrastructure needed for 5G.

User equipment, such as the RAN and NR interface, and the 5G core network, which uses a service-based architecture framework with virtualized network services, make up a standalone 5G deployment. Typically hardware-based network operations are virtualized and executed as software.

The global 5G infrastructure market size was worth USD 5 billion in 2021. It is estimated to reach USD 167 billion by 2030, growing at a CAGR of 48.5% during the forecast period (2022–2030).

Here are the latest trends in 5G infrastructure:

• Independent 5G Implementation: Gaining popularity are standalone 5G networks that operate independently of the current 4G LTE infrastructure. To fully employ 5G's capabilities, such as ultra-low latency and network slicing, these networks make use of a 5G core and radio. In order to give clients with additional capabilities, wireless providers are developing their packet core in tandem with radio access technologies.

• Small Cell Networks: Carriers are constructing small cell networks to supplement the current macro cell towers. In densely populated locations, small cells can focus network resources, boosting capacity and meeting rising demand. Carriers can enhance 5G connection for customers by placing tiny cells near residences, venues, and enterprises.

• Large-scale MIMO: In 5G base stations, massive MIMO systems with hundreds of antennas are being used. Compared to single-input stations, these systems provide higher network capacity and coverage by concentrating energy into fewer areas. However, there are obstacles to overcome when adopting massive MIMO, such as its size and high processing power needs.

• Accessible RAN: Through open interfaces and cloudification, the Open Radio Access Network (Open RAN) facilitates the disaggregation of software and hardware. This strategy boosts competition, flexibility, and innovation because any business can be a supplier. One possible direction for 5G rollout is open RAN.

• AI Incorporation: Artificial intelligence is being used by more than 50% of telecom businesses to help with the complicated issues involved in developing 5G networks. AI presents numerous prospects for 5G network optimization and the creation of new 5G apps.

• High Growth in Revenue: By 2023, it's expected that 5G service sales will total $315 billion, mostly from mobile customers switching to 5G networks. By 2023, 5G services are predicted to generate at least 35% of operators' overall income.

The main challenges in deploying 5G infrastructure include:

• Network Development and Small Cell Deployment: A key component of 5G deployment is the use of small cell technologies in heavily populated areas to boost network capacity. Because mm Wave frequencies have limited coverage, small cells need an ultra-dense grid, which means numerous antennas are needed to successfully service specific locations.

• Costs: Installing the 5G infrastructure's hardware, software, spectrum acquisition, configuration, testing, and maintenance will set you back a good amount of money. Operators have financial difficulties because to the setup costs associated with microcells and small cells as well as the ongoing requirement for updates.

• Backhaul Problems: 5G networks' dense tiny cells need to be able to handle large amounts of traffic via backhaul connections. Deployment issues arise with upgrading backhaul technology to meet 5G expectations, such as employing fiber optics for high-speed connections.

• Spectrum Availability and Frequency Bands: In order for 5G technology to function effectively, high-frequency bands must be available, which means that operators must get spectrum licenses. The viability and characteristics of 5G networks are significantly impacted by the cost and availability of spectrum as well as the choice of appropriate frequency bands.

• Competent Labor and Education: 5G network deployment calls for a workforce with the necessary skills to adopt new technology. One problem is that there aren't enough qualified engineers with experience in 5G technology. To close this talent gap and guarantee effective network rollout, reskilling programs and training activities are required.

• Regulatory Compliance: Implementing 5G infrastructure presents a number of challenges, including spectrum licensing, data privacy, security, and environmental restrictions. Operators are required to guarantee compliance and abide by regulations specific to each region or country where the network is deployed.

The market for 5G infrastructure is expected to have grown significantly due to large investments and advances in technology. With more than 4800 fundraising rounds completed, the average investment in the sector is USD 51 million, demonstrating the high level of investor trust. Because of its wider coverage, the sub-6 GHz spectrum continues to be dominant, but the millimeter Wave section, which offers extremely high speeds and minimal latency, is expected to increase significantly. It is anticipated that 5G connections will significantly increase in North America; by 2025, 63% of all mobile connections in the region will be 5G. Key centers of innovation are found in the UK, Germany, China, India, and the USA.

Due to the high data bandwidth requirements for applications like cloud computing and virtual meetings, the enterprise sector is leading the adoption of 5G, while the industrial sector is expected to develop due to the requirement for seamless communication in Industry 4.0 applications. With over 1.3 million workers worldwide, the industry creates a lot of jobs and places a high priority on research and development, as shown by the more than 300 grants and 20,800 patents it has received.As technology data traffic reaches an astounding 2.6 billion TB (or 2600 EB), 76% of that traffic is predicted to come from 5G, and by 2028, all technology data traffic will have reached 3.4 billion TB (or 3400 EB), illustrating the exponential growth trajectory of 5G connection.
