Things You Need To Know About Network Management Systems


A network management system is an application that allows network management operators to manage the hardware and software components of smaller individual networks within a bigger network. The advantages of using a centralized management system are that it saves time, cost and increases productivity. Only one admin is required and each team member can easily access data anytime at their own workstations.

What has changed in 4G network architecture?

There are a few basic evolutionary changes from 3G to 4G network architecture. This LTE (long-term evolution) network only supports packet-switched services. The objective is to provide IP (Internet Protocol) connectivity between User Equipment and the Packet Data Network. 4G networks have the same bandwidth as a 3G network, but a much higher frequency range of 2 to 8GHz. While circuit switching was a feature of 3G networks, it is now redundant and has been removed.

Optimization of 4G networks

The optimization of the 4G network is done with the help of KPI (key performance indicators). The performance of these networks is assessed to provide better subscriber quality and to use the network resources more efficiently. Retainability and mobility KPI are used to check the ability of the network to retain services for a user and handle the movement of users.

Technology training — what are the essentials?

There are many certified courses for 4G technology training. These are mainly aimed at engineering students and the various modules that are covered would include Network Architecture, E-UTRAN (a radio access network and the air interface of LTE) and so on. The training could be held in different modes, in a corporate environment or with an instructor to guide. In 5G technology training, there are many chapters, the most important of which are; is Security Training, Wireless Training, D2D (device-to-device) communication training and C-RAN (Cloud — Radio Access Network) training. These courses are short such that professionals employed in other fields will also be able to afford the time to study them. Each of the training modules listed above takes a maximum of 5 days on most training websites.

What is NFV and how does it simplify network operations?

Network Functions Visualization (NFV) aims to visualize networks running on dedicated hardware. Moving these to virtual networks reduces the overall cost of managing them and thus accelerates the service deployment of network operators. The concept behind this is that, instead of purchasing expensive hardware, network administrators could invest in cheaper electronics used to manage the networks virtually. All these functions are then collapsed onto a single physical server. This allows operators to become independent of hardware appliances. This also reduces the power consumption of the network considerably. These are a few of the salient features of NFV.
