4g vs 5g network architecture

5G Spectrum Massive MIMO and beam steering antennas 5G delivering lower latency  5G Resources and links, 5G is the 5th generation of mobile networks, a significant evolution of todays 4G LTE networks. Award Solutions invests heavily in technology, research, engineering, and labs to ensure our customers make the most of their resource and network investments. Paul joined Award Solutions in 2012, and has over 28 years of experience in telecom. Currently, all commercial 5G deployments are based on NR non-standalone (NSA) technology which uses existing LTE radio access for signaling between devices and the network, and  Evolved Packet Core (EPC) networks which are enhanced to support 5G NSA. Network functions that used to run on dedicated hardware for example a firewall and encryption at business premises can now operate on software on a virtual machine. 4G sector base station and 5G base station with a new multi element massive MIMO antenna array. The benefit to users is that more people can simultaneously connect to the network and maintain high throughput. The Access and Mobility Management Function (AMF) serves part of the role of the 4G MME, that of mobility management. Additional mobile spectrum above 6 GHz, including the 26-28 GHz bands often referred to as millimeter (mm) Wave, will provide significantly more capacity compared to the current mobile technologies. The overall uplink traffic flow is from UE to gNB to UPF and the reverse for downlink traffic. But none of those will be possible without 5G Core (5G Core) and New Radio (NR) standalone technologies. As shown 5G network uses flat IP concept so that different RANs (Radio Access Networks) can use the same single Nanocore for communication. Future 5G deployments may use mmW frequencies in bands up to 86 GHz. Discover 5G Core Network Functions Compared to 4G LTE by Paul Shepherd. At the Ericsson Blog, we provide insight to make complex ideas on technology, innovation and business simple. These industry verticals include, manufacturing and automotive, private and mission critical networks and wireline access. Small cells are essential for the 5G networks as the mmWave frequencies have a very short connection range. Where appropriate, these new network elements are compared to their equivalents in the 4G Evolved Packet Core (EPC). The Radio Access Network - consists of various types of facilities including small cells, towers, masts and dedicated in-building and home systems that connect mobile users and wireless devices to the main core network. top, Mobile handsets, tablets and hot spots equipped with 3G, 4G and 5G connectivity were launched in 2019 and low latency and widespread machine to machine applications using 5G will be developed in the coming years. Initial 5G services commenced in many countries in 2019 and widespread availability of 5G is expected by 2025. top, Fixed wireless access for homes and enhanced mobile broadband services are the first applications using new 5G phones, tablets, wireless access modems and hot spots. I hope it’s clear why you need to embrace them to stay competitive and remain a relevant player in your market. The 4G network architecture was defined to meet the mobile network needs that existed at that time, but today it presents certain limitations. The list of capabilities goes on, but here are a few others: Is 5G Core and NR SA future proof? We help companies tackle new technologies by equipping their teams with knowledge and skills. The UPF anchors the UE IP addresses. These same functions need to be performed in the 5G core, together with new capabilities, however, the architecture is different. What will 5G enable? Learn about the architecture for the 5G packet core, including a description of the functions of the network elements. Some functions have been split into multiple sperate components, while some functions have been combined. 5G networks are designed to work in conjunction with 4G networks using a range of macro cells, small cells and dedicated in-building systems. The 5G Core architecture and the cloud native/microservices implementations will reduce this complexity while keeping operating expenses low. The Non-3GPP access Inter-Working Function (N3IWF) is similar to the ePDG in the 4G EPC, which is a secure gateway for the UE access non-trusted networks, such as Wi-Fi and the public internet. The UDM generates authentication vectors when requested by the AUSF. LTE (4G) Network Architecture. Businesses will operate and make key decisions driven by data, innovate in agriculture, smart farms and manufacturing, paving the way for cost savings, better customer experience and long term growth. Redefine customer experience in real time, Service exposure and traffic steering functionalities introduced in the 5G Core will provide additional tools for service differentiation, Enhanced QoS model that is more flexible and granular than in 4G networks and that will allow multiple services (QoS flows) per PDU Session, Security is improved to secure end-to-end communication with enhanced key handling and a unified authentication model for applications and network users, Service differentiation per geographical area is also increased which is, for instance, useful to control access to FWA services or other localized services. A UE may be configured with a list of subscribed network slices and can request these during the registration procedure. 5G network architecture will be designed based on access sites and three-layer DCs. Implementing a virtual, dynamic and configurable RAN allows the network to perform at very low latency and high throughput, but it also allows the mobile network to adjust to changes in network traffic, network faults and new topology requirements. Network Slicing – enables a smart way to segment the network for a particular industry, business or application. Information about subscribers, application-specific data, and policy data can be stored in the UDR. LTE network nodes. Like 2G, 3G evolved into 3.5G and 3.75G as more features were introduced in order to bring about 4G. 5G will enable instantaneous connectivity to billions of devices, the Internet of Things (IoT) and a truly connected world.
