5G MOBILE CONCEPT An Eye view on the futur generation of phones”By santosh dasUnder the guidanceof Prof Ravindra E
Mobile and wireless networks have made tremendous growth in the last fifteen years. Nowadays many mobile phones have also a WLAN adapter Multimode user terminals are seen as must have for 4G, but different security mechanisms and different QoS support in different wireless technologies remain a challenge integration among different wireless networks is functioning in practice even today. But, different wireless networks from a single terminal are used exclusively, that is, there is no combining of different wireless access technologies for a same session (e.g., FTP download) The 5G terminals will have software defined radios and modulation scheme as well as new error-control schemes can be downloaded from the Internet on the run. The development is seen towards the user terminals as a focus of the5G mobile networks. The paper also proposes intelligent Internet phone concept where the mobile phone can choose the best connections by selected constraints and dynamically change them during a single end-to-end connection.
Developed in 1980s & completed in early 1990’s Speed up to 2.4kbps AMPS first launched by US & a 1G mobile system Allows users to make voice calls in 1 country The analog “brick phones” and “bag phones” are under 1G technology Cell phones are used millions and billions of users worldwide The main difference between two succeeding mobile telephone systems, 1G and 2G, is that the radio signals that 1G networks use are analog, while 2G networks are digital 1G is only modulated to higher frequency, typically 150 MHz and up.
Fielded in the late 1980s & finished in late 1990s Speed up to 64kbps Digital handsets that are used today 2G technology is more efficient voice transmission with digital signal 2G technologies enabled the various mobile phone networks to provide the services such as text messages, picture messages and MMS (multi media messages)
Generation between 2G and 3G 2.5G represents handsets with data capabilities over GPRS Failure in bringing any new evolution 2.5G is a stepping stone between 2G and 3G cellular wireless technologie It does not necessarily provide faster services because bundling of timeslots is used for circuit switched data services (HSCSD) as well.
3G wireless system Speeds from 125kbps-2Mbps Performance in computer networking (WCDMA, WLAN Bluetooth) & mobile devices area (cell phone & GPS) Data sent through packet switching technology Voice calls interpreted using circuit switching Access to Global Roaming & Clarity in voice calls Fast Communication, Internet, Mobile T.V, Video Conferencing, Video Calls, (MMS), 3D gaming etc
4G wireless system Conceptual framework & discussion point to address future needs of a high speed wireless network Both cellular & broadband multimedia services everywhere Expected to emerged around 2010 – 2015 arrival Smooth global roaming ubiquitously with lower cost. 4G is a conceptual framework and a discussion point to address future needs of a high speed wireless network Application are mobile tv,video on demand,video conferencing etc
5G wireless system Complete wireless communication with almost no limitation Multi-Media Newspapers, watch T.V programs with the clarity as to that of an HD T.V. Faster data transmission that of the previous generations Real wireless world with no more limitation with access and zone issues. 5G is a completed wireless communication with almost no limitation; somehow people called it REAL wireless world Cognitive radio tecnology,knowns as smart radio which dynamically allot frequency when the frequency used by other user are not in use. Internet protocol version 6 (IPv6), where a visiting care-of mobile IP address is assigned according to location and connected network
5G : 5th Generation Mobile Technology Change the means to use cell phones within very high bandwidth Advanced features: powerful and in huge demand in future Offers more power & features in hand held phone large phone memory, dialing speed , clarity in audio and video etc
A new revolution in mobile market World Wide Cellular phones Extra ordinary data capabilities High connectivity Bright future
5G terminals will have software defined radios. New error-control schemes. Access to different wireless technologies. Combine different flows from different technologies. Choice among different wireless/mobile access. Network providers for a given service.
Application Layer Application(Service)Presentation layer Session Layer Open Transport Protocol Transport Layer Upper network layer Network Layer Lower network layer Datalink Layer Open Wireless Architecture Physical Layer
Physical and MAC layers (OSI layer 1 and OSI layer 2) definethe wireless technology.For these two layers the 5G mobile networks is likely to bebased on Open Wireless Architecture.
All mobile networks will use Mobile IP. Each mobile terminal will be FA A mobile can be attached to several mobile or wireless networks at the same time. The fixed IPv6 will be implemented in the mobile phone Separation of network layer into two sub-layers o Lower network layer (for each interface) o Upper network layer (for the mobile terminal) The middleware between the Upper and Lower network layers (Fig. 3) maintain address translation from Upper network address (IPv6) to different Lower network IP addresses (IPv4 or IPv6), and vice versa.
Terminals will be suitable to have transport layer that is possible to be downloaded and installed. Possibility to download (e.g., TCP, RTP etc. or new transport protocol) version which is targeted to a specific wireless technology installed at the base stations. This is called here Open Transport Protocol - OTP.
Intelligent QoS management over variety of networks. Select the best wireless connection for a given service. Service quality testing & storage of measurement information in information DB in the mobile terminal. QoS parameters will be stored in a database Intelligent algorithms running in the mobile terminal as system processes-provide the best wireless connection.
High resolution, bi-directional large bandwidth shaping. Advanced billing interfaces: attractive and effective. Subscriber supervision tools for fast action. High quality services based on Policy to avoid error. Large broadcasting of data (GB) supports almost 65,000 connections. Transport class gateway with unparalleled consistency. More accuracy by traffic statistics.
Remote management :better and fast solution Remote diagnostics 25 Mbps connectivity speed. Virtual private network. All delivery service out of business prospect. High uploading and downloading speed enhanced and available connectivity just about the world.
