The high reliability and ultra-fast speed of 5G networks enhance the current capabilities of 4G networks, which themselves built on 3G¡¯s application and data technology. However, there are significant differences between 5G and 4G, including:

1. 5G technology capabilities:?5G technology offers a massive step forward in terms of mobile technology capabilities. Current 4G Long-Term Evolution (LTE) technology can only use lower frequency bands, which operate up to 6 GHz. However, 5G¡¯s radio bands are able to handle between 30 GHz and 300 GHz. This high frequency enables 5G to offer significant speed increases, support huge data transfers, and free up bandwidth.
2. Significant speed:?The key difference between 5G vs. 4G is the significant additional speed that 5G networks offer. 4G networks have a peak speed of around 1 GB per second, while 5G can offer 20x that level. That means much faster mobile downloads without having to connect to Wi-Fi.?
3. Greater capacity:?4G networks struggle to handle multiple devices connecting in the same location, such as at busy concerts or sports events. 5G solves this problem by providing high-precision transmissions to each individual device, which allows it to handle up to 1 million devices in a square kilometer. That precision is crucial as mobile device usage continues to increase exponentially.?
4. Innovative mobile traffic usage:?4G networks¡¯ radio waves can carry limited amounts of information, which is problematic because? shows data traffic growing by 60% every year. 5G enables more people to use networks. It meets the demand for increased usage of social media, online gaming, and video streaming. It also enables crucial data-intensive use cases in the healthcare and industrial sectors, such as ambulance teams streaming an incident response directly to a hospital.
5. More than a mobile network:?The processing power of 5G takes it far beyond current network capabilities. It can become a distributed data center that performs processing tasks and brings edge computing closer to users. This allows the network to handle processing-intense tasks, such as games and augmented reality filters, instead of users¡¯ phones, which improves performance and saves phone batteries. This could result in new innovations such as lightweight AR glasses and fleets of delivery drones.

Explaining 5G relies on understanding the following core components of the technology:

1. 5G New Radio (NR) which defines the air interface upon which user, machines, and devices connect and send and receive data. 5G NR includes several low and mid-frequency bands in the sub-7 GHz range, defined as FR1, as well as higher frequency bands above 24 GHz, defined as FR2/mmWave. 5G frequency includes all previous cellular spectrum and additional spectrum in the sub-7 GHz frequency range and beyond. A key reason that additional spectrum is being made available is to overcome the physical limitations associated with throughput and bandwidth.
2. 5G Next Generation Core (5G NGC) is the ¡°brain¡± of the 5G network, providing control and management for the network, its services, and the connected devices. The new 5G core, as defined by 3GPP, utilizes cloud-aligned, service-based architecture (SBA) that spans across all 5G functions and interactions, including authentication, security, session management and aggregation of traffic from end devices. The 5G core further emphasizes Network Function Virtualization (NFV) as an integral design concept with virtualized software functions capable of being deployed in an agile and distributed manner.
3. Multi-access Edge Computing (MEC) is one of the key pillars for meeting the demanding KPIs of 5G, especially as far as low latency and bandwidth efficiency are concerned.? MEC is also expected to play an essential role in the transformation of mobile networks into versatile service platforms for industry and other specific customer segments.
4. IP Multimedia Subsystem (IMS) delivers IP based multimedia services, enabling mobile operators to offer a new generation of rich multimedia services. IMS offers access to IP based services independent of the access network.?
