Fifth Generation Cellular Communications (5G)

What is 5G?

5G stands for the fifth generation of wireless cellular communications technology. It’s the successor to 4G and provides faster connectivity for mobile devices.

Benefits of 5G

Speed and Bandwidth
  • 5G networks offer higher download speeds, with a peak speed of 10 gigabits per second (Gbit/s) when there’s only one user in the network.
  • The increased bandwidth allows 5G to deliver faster speeds than 4G, improving the quality of Internet services, especially in crowded areas.
Cellular Networks
  • Like its predecessors, 5G networks are cellular networks. The service area is divided into small geographical areas called cells.
  • All 5G wireless devices within a cell connect to the Internet and the telephone network via radio waves through a base station and antennas.
Applications and Connectivity
  • 5G can connect more devices, making it suitable for the Internet of Things (IoT) and machine-to-machine communication.
  • Due to its increased bandwidth, 5G networks may also compete with existing ISPs (such as cable internet) and enable new applications.
  • The industry consortium responsible for setting 5G standards is the 3rd Generation Partnership Project (3GPP).
  • 5G uses 5G NR (New Radio) software, which defines the system’s parameters and features.
Frequency Bands
  • Some network operators use millimetre waves (FR2) in 5G terminology for additional capacity and higher throughputs.
  • Millimetre waves have a shorter range but provide more capacity. However, they face challenges passing through building walls and obstacles.


5G and the Aerospace Industry

Not surprisingly, therefore, 5G technology is poised to revolutionize the aerospace industry, offering significant benefits across various aspects of aviation. This is how it is making an impact:

In-Flight Connectivity (IFC)
  • 5G enables faster and more reliable in-flight Wi-Fi. Passengers can enjoy seamless internet access, streaming, and communication during their flights.
  • Companies like Gogo are leveraging 5G to enhance their IFC networks.
Mission-Critical Services
  • The integration of 5G wireless communication technologies in aerospace aims to boost mission-critical services.
  • Ultra-reliable, low-latency communication ensures critical data transfers and interconnected devices and systems.
