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 Fielded in the late 1980s & finished in late 1990s Speed up to 64kbps Digital handsets that are used today voice transmission with digital signal Generation between 2G and 3G 2.5G represents handsets with data capabilities over GPRS Failure in bringing any new evolution 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 2010 – 2015 arrival Smooth global roaming ubiquitously with lower cost. 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 world wireless or called “WWWW: World Wide Wireless Web. 5G : 5th Generation Mobile Technology 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 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 Presentation layer Session Layer Transport Layer Network Layer Application(Service) Open Transport Protocol Upper network layer Lower network layer Datalink Layer Physical Layer Open Wireless Architecture Physical and MAC layers (OSI layer 1 and OSI layer 2) define the wireless technology. For these two layers the 5G mobile networks is likely to be based 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. www.FreeWiMaxinfo.com www.ieee.com/explorer www.hubpages.com
