Challenges in 5g Technology

5G technologies are a new paradigm supported by the European Commission (EC) to overcome the challenges of next-generation networks. Extraordinary high speeds and capacity, multi-tenancy, fixed and wireless access network are only a few examples of the complex demands that 5G aims to undertake. The accommodation of such features requires efforts in different network technology domains at various levels. Here, we see how the relative 5G network features challenge the current generation of access networks, both fixed and wireless and data centers, from an end-to-end network service point of view. New business models focused on the vertical market. Vertical markets include several segments such as Internet Connected Vehicles. Factories of the future. Smart cities which require public transportation. Medicine, healthcare and robot-assisted survey. Smart grid flow management.

A car is a common form of transportation and safe driving is an important consideration. Humans errors are responsible for accidents occurrence. To tackle this problem the Transportation sector has adopted technological innovation and to make transportation safer, efficient and more sustainable. There are three areas in which 5G technology have to play a role so that the transportation sector can improve its automotive transportation. Providing Internet access to the car to entertain passengers. To provide driving assistance ability to make cars autonomous, thanks to artificial intelligence algorithms. The first area is the extension of today’s 4G service to provide entertainment to people. The second area is aimed to make car intelligent which was not provided early. This, in turn, improves the safety of people. By installing 5G into cars will make the driver get information about the conditions of roads, will make drivers to make the right decisions.

Competitiveness does not depend solely on innovation and the evolution of products, but also on modernizing businesses and their means of production. 5G in particular is expected to be a very versatile technology, capable of undergirding a very wide array of uses, and could go a long way in furthering companies transition to digital technologies and solutions.

5G is technology which uses both low and high frequency. The spectrum diversity is bound up with 5G: extended coverage, ultra-high speeds, low power consumption. Satellite industry is now adopting 5G to define new generation network.

Today, mobile network rollouts are essentially based on the use of macro base stations: installations that are equipped with hig-power antennae deployed to guarantee coverage for a relatively wide area, providing good quality of service. However, this continually growing demand for capacity already requires operators to increase the density of their networks with smaller and smaller cells.5G-which will probably bring about a sizeable increase in data traffic and which will use millimeter wave frequencies whose propagation capabilities are weak-will no doubt require the widespread deployment of low-power base stations (small cells). The current regulatory framework stipulates that base stations whose power requires an opinion, an agreement or a statement from the National Frequency Agency(ANFR). The amount of the tax varies according to transmission power, the type of installation and deployment location.5G small cells will likely use variable transmission powers of between 1W and 25W.Access to elevated and “semi-elevated” locations. To perform their deployments successfully, mobile operators have traditionally needed to install their base stations in elevated locations (towers, rooftops, etc.).This will continue to be true with 5G networks, but will be even more challenging for two main reasons:

1. 5G antennae will probably be larger than current 2G,3G or 4G antennae, because of the MIMO processing that will require the use of a very large number of radiating elements. Additional antennae compatible with new 5G bands with no doubt also needed to be deployed reuse of existing masts could be problematic.
2. New transmission sites will need to be found. This search for new sites will also to be carried out to install small cells in semi-elevated locations, but with extra care as the density will be very high. Operators will thus be required to deploy their equipment on urban furniture and infrastructures such as lampposts, public buildings, bus shelter etc.

European regulation on safeguarding an Open internet, adopted by the European Parliament and Council on 25 November 2015, for which European regulators require an additional nine months to specify the rules governing its application, introduces the principle of net neutrality as one of the top priorities in the standardization hierarchy.Net neutrality is an overriding principle that guarantees equal treatment for all data traffic on the internet. In particular, it excludes any form of discrimination with respect to the source, the destination or the content of data flows.
