Wireless communication started in early 70s and the fifth generation should make an important difference and more services and benefits to the world over 4G. fifth generation should be more intelligent technology that inter connects the entire world without limits. this generation is excepted to be released in around 2020, uninterrupted access to information entertainment and communication will open new dimension to our lives and change our lifestyle significantly.
(1) QUALITY OF SERVICES
Next Generation Networks (NGN) consists of support functionalities for data transport, and control transport, as well as functionalities for support of services and applications. The measurement of traffic is abasic control activity in order toprovide Quality of Service. In addition, 5G communication system is designed by the finest Quality of Service (QoS).Quality of Service (QoS) refers to a network ‘s ability to achieve maximum bandwidth and deal with othernetwork performance elements like latency, error rate and uptime. Quality of service also involves controllingand managing network resources by setting priorities for specific types of data (video, audio, files) on the network. QoS is exclusively applied to network traffic generated for video on demand, IPTV, VoIP, streaming media, videoconferencing and online gaming. The primary goal of quality of service is to provide priority to networks, including dedicated bandwidth, controlled jitter, low latency and improved loss characteristics. Its technologies supply the elemental building blocks that will be used for future business applications in campus, wide area networks and service provider networks. There are three fundamental components for basic QoS implementation :
• Identification and marking techniques for coordinating QoS from end to end between network elements.
• QoS within a single network element.
•QoS policy, management, and accounting functions to control and administer end-to-end traffic across a network.
(2) WHY 5G
Very High speed, high capacity, and low cost per bit. It supports interactive multimedia, voice, video, Internet, and other broadband services, more effective and more attractive, and have Bi- directional, accurate traffic statistics. 5G technology offers Global access and service portability. It offers the high-quality services due to high error tolerance. It is providing large broadcasting capacity up to Gigabit which supporting almost 65,000 connections at a time. More applications combined with artificial intelligent (AI) as human life will be surrounded by artificial sensors which could be communicating with mobile phones.
• 5G technology use remote management that user can get better and fast solution.
• The uploading and downloading speed of 5Gtechnology is very high.
• 5G technology offer high resolution for crazy cell phone user and bi-directional large bandwidth shaping.
• 5G technology offer transporter class gateway with unparalleled consistency
The development of the mobile and wireless networks is going towards higher data rates and all-IP principle. Mobile terminals are obtaining each year more processing power, more memory on board, and longer battery life for the same applications. 5G include latest technologies such as cognitive radio, SDR, nanotechnology, cloud computing and based on All IP Platform. It is expected that the initial Internet philosophy of keeping the network simple as possible, and giving more functionalities to the end nodes, will become reality in the future generation of mobile networks, here referred to as 5G.
