Chapter 1 : INTRODUCTION
1.1 2G – 2nd Generation Mobile System
1.1.1 GSM, IS-95, cdmaOne
1.1.2 Low-bit-rate data
1.2 Higher-data-rate service: Cost of the services provided by the 2G is very expensive.
1.3 3G – 3rd Generation Mobile System
New technology Are invented to fulfill customers need regarding network like ,
1.3.1 GPRS: -General packet radio service (GPRS) is a packets oriented mobile data service available to users of the 2G cellular communication systems global system for mobile communications(GSM), as well as in the 3G systems. In 2G systems, GPRS provides data rates of 56-114 kbit/s GPRS data transfer is typically charged per megabyte of traffic transferred.
1.3.2 IMT-2000: -International Mobile Telecommunications-2000 (IMT-2000)', better known as 3G or 3rd Generation, is a family of standards for mobile telecommunications defined by the International Telecommunication Union, which includes GSM EDGE, UMTS, and CDMA2000 as well as Services include wide-area wireless voice telephone, video calls, and wireless data, all in a mobile environment. Compared to 2G and 2.5G services,
1.3.3 Bluetooth: - This is short range wireless network to connect component without wires .components like camera , headset , scanner and other devices to connect to the computer by mearly being brought within range.
1.3.4 WLAN: - Each computer has the radio modem and antenna and which it can communicate with other computer systems.
1.3.5 HiperLAN: - This is same as the WLAN but useful for more distance and bit rate is much lower.
1.4 Independent systems, all have there own shortcomings.
1.5 A single system is needed to replace all of them – 4G.
Wireless mobile communications systems are uniquely identified by "generation designations. Introduced in the early 1980s, first generation (1G) systems were marked by analog frequency modulation and used primarily for voice communications. Second generation (2G) wireless communications systems, which made their appearance in the late 1980s, were also used mainly for voice transmission and reception The wireless system in widespread use today goes by the name of 2.5G-an "in between " service that serves as a stepping stone to 3G. Whereby 2G communications is generally associated with Global System for Mobile (GSM) service, 2.5G is usually identified as being "fueled " by General Packet Radio Services (GPRS) along with GSM. In 3G systems, making their appearance in late 2002 and in 2003, are designed for voice and paging services, as well as interactive media use such as teleconferencing, Internet access, and other services. The problem with 3G wireless systems is bandwidth-these systems provide only WAN coverage ranging from 144 kbps (for vehicle mobility applications) to 2 Mbps (for indoor static applications). Segue to 4G, the “next dimension” of wireless communication.
Digrams of all 2g, 3g n 4g
• 4G – 4th Generation Mobile System
• Key Features from Users’ Point of View: -
• High usability: Anytime, anywhere, and with any technology .It will really helpful to use remote information at any time, at any physical condition, and even use any technology which is given above.
• Support for multimedia services at low transmission cost like video, audio, text document to transfer through this technology. So it will be more users friendly.
• Personalization: In this any person can perform any operation as per his/her requirement more efficiently. Even at any time.
• Integrated services: In this all services can be integrated for more good uses.
• All-IP based network – any system / any time / any where
• Telecommunications services + data and multimedia services. Personalized service Facilities for integrated services
Chapter: 2 OVERVEIW OF THE CHALLENGES
2.1 Mobile station
2.2 System
2.3 Service
The fourth generation of mobile networks will truly turn the current mobile phone networks, in to end to end IP based networks, couple this with the arrival of IPv6, every device in the world will have a unique IP address, which will allow full IP based communications from a mobile device, right to the core of the internet, and back out again. If 4G is implemented correctly, it will truly harmonies global roaming, super high speed connectivity, and transparent end user performance on every mobile communications device in the world.
4G is set to deliver 100mbps to a roaming mobile device globally, and up to 1gbps to a stationary device. With this in mind, it allows for video conferencing, streaming picture perfect video and much more.
It won’t be just the phone networks that need to evolve, the increased traffic load on the internet as a whole (imagine having 1 billion 100mb nodes attached to a network overnight) will need to expand, with faster backbones and oceanic links requiring major upgrade.
4G won’t happen overnight, it is estimated that it will be implemented by 2010, and if done correctly, should take off rather quickly.
