5G Network Architecture: Requirements and Trends
5G provides greater performance and versatility than previous wireless platforms. That means it requires a more complex and robust infrastructure. Arm and its partners are rapidly resolving every 5G challenge to deliver technology for building seamless networks.
- Radio and Spectrum. 5G features low-band (below 1 GHz), mid-band (1 GHz to 8 GHz), and high-band (24 GHz to 40 GHz) for different applications use cases. Each band has its own set of requirements for performance, capacity, speed, and latency.
- Connections. 5G can support up to a million devices per square kilometer for pervasive IoT services.
- Reliability. Network slicing allows isolated services for greater reliability and quality of service.
- Public and Private. 5G services can be made available through public carriers and be set up to manage discreet facilities, such as factories and other campuses.
- Real-Time Services. Latency can be reduced to up to 1 millisecond to enable effective real-time visibility and control.
- A Spectrum of Base Stations. Outdoor base stations can contain base band units, multiple active antenna units, and edge data servers while pico base stations provide coverage for 40K-50K square feet.
- A Spectrum of Cells. Base stations link to macro cells (10 watts, kilometer ranges), micro cells (5-10 watts, 100s meters), pico cells (100-250 mW, 10s of meters) and femto cells (10-100 mW, meters).
An Ecosystem Spanning Radios to Core Networks
Here is how some of our partners are taking advantage of Neoverse in 5G infrastructure:
Vodafone, NXP, Telco Systems, and Arm collaborate on universal customer premise equipment to increase performance, reduce energy consumption and extend product lifecycles.
Marvell’s Arm-based Octeon X2 platform processors help Nokia and other leading vendors increase throughput and performance, while lowering power consumption in differentiated 5G solutions.
Sunsea, one of China’s leading IoT companies, creates reconfigurable Arm-based 5G cloud base stations for office campuses and manufacturing.
Lenovo is deploying Arm-based silicon across its 5G product portfolio, including centralized units (CU), distributed units (DU) remote radio units (RRU) and RRU hubs.
