FUTURE WIRELESS TECHNOLOGY 5 G

Abstract• Understanding the greater importance of wireless communication in

the future for both academies and industries around the world have initiated the study of the next generation, namely 5G of wireless communication systems. Fifth Generation mobile network concept which is seen as user-centric concept instead of operator-centric as we have in 3G or service centric concept as seen for 4G. In the proposed concept the mobile user is on the top of all.

ObjectiveThis Paper deals with the Contribution of various communication technologies for making 5G mobile telecommunication faster and making it user friendly.

MethodologyAuthor studied the development and impact of various communication technologies in communication field and how it can contribute in 5G mobile communication.

Introduction

Index Terms- Flat IP Netwrk,BDMA,5G Architecture, Nanotechnology, Cloud

Computing.

The 5G technology also known as 2020 wireless network technology is the foremost phase of wireless communication standards ahead of current 4G/IMT standard. The coming 5G technology and Information & Communication technology (ICT) network signify evolution of the globally connected digital society.

The different generations of wireless technology can be differentiated on the following aspects-

Radio access, Data rates bandwidth and switching schemes.

5G Network

• Converged system with multiple access technology integrated together.

• Uses the flat IP concept.

• Uses Nanotechnology as defensive tool.

• The 5G communication system is envisioned as the real wireless network, capable of supporting wireless world wide web (wwww).

• Can be called REAL wireless world.

• A core network, or network core, is the central part of a telecommunications network that provides various services to customers who are connected by the access network. One of the main functions is to route telephone calls across the PSTN.

• A radio access network (RAN) is part of a mobile telecommunication system. It implements a radio access technology. Conceptually, it resides between a device such as a mobile phone, a computer, or any remotely controlled machine and provides connection with its core network (CN).

Flat IP• Makes easy for different RAN to upgrade into a single

Nano core.• It’s able to deliver the real-time data application over

mobile broadband networks.• Provide a way to identify devices using symbolic names.• Removes multiple elements from the network chain.

Drawback

• Many security concern related to operation.

Benefits of flat IP

• Lower cost.• Reduced system latency.• Developed radio access and core network evolution.

Benefits to Mobile operator

• Reduced number of network elements in data path to lower operation costs and expenditure.

• Minimize system latency and enable application with a lower tolerance for delay.

• Evolve radio access and packet core networks independently of each other to a greater extent than in the past.

5 G Architecture 5G is the convergence of 3 technologies-i. Nanotechnologyii. Cloud Computingiii.All IP Platform

Nanotechnology

• Advantages of using Nanotechnology

• Size of equipment is reduced.• Perfection in security.• Faster and reliable.

Impact on Mobile as well as core network is the mode of operation of the Nanotechnology.

Cell phone enhanced with the carbon nanotube will be introduced soon which comes under the nanotechnology. In 5G Nano core these mobile are referred as NanoEquipments as they are geared up with nanotechnology.

Feature of Nanoequipments•Self cleaning.•Self powered.•Sense the environment.•Flexible.•Transparent.

Cloud Computing Technology used for maintaining data and application that uses the internet and central remote server is known as cloud computing.

Segments of cloud computing• Application.• Platform.• Infrastructure.

All IP network/NGN

• Next Generation Networks are packet-switched and use IP at the network layer. This provides an independent platform through which access services such as 4G can use the network. The principle idea is to have seamless communication; people can be connected anywhere and anytime.

Different multiple accessing technique

. FDMA-In Frequency Division Multiple Access the corresponding frequency division and allocation takes place. which divides and allocates the available frequency resources to maximize the resource utility efficiency.

• CDMA-Code Division Multiple Access separates call by code. Every bit of a conversation is been tagged with a specific and unique code. The system gets a call, it allocates a unique code to that particular conversation, and now the data is split into small parts and is tagged with the unique code given to the conversation of which they are part of.

• TDMA- Time Division Multiple Access,the division of calls happens on time basis. The system first digitizes the calls, and then combines those conversations into a unified digital stream on a single radio channel.

BDMA• BDMA-(Beam Division Multiple Access)• The Latest allocation technique in which an orthogonal

beam is allocated to each mobile station.

Conclusion• 5G- User Centric.5G - a promising Generation of

wireless communication that will change people’s live and nanotechnology, Cloud computing, All IP are the next great technology wave.
