Abstract
Parameter optimization, such as antenna tilting and CPICH power, can be used to adapt the traffic capacity of 3G systems to traffic demands which are varying in the space and time dimensions. The goal of this thesis is to investigate how parameter optimization can be implemented, both in the 3G cellular system’s initial planning stage to optimize the network for CAPEX saving as well as after the deployment of the network, to increase the capacity of the system. For this purpose, appropriate models, including the space and time domain dynamics of the traffic modeling the moving hotspot characteristics, have been integrated into a system simulation tool. Meta-heuristics techniques such as Tabu Search and Simulated Annealing have been implemented to solve this NP-hard problem. Results show that the existence of optimal configurations can have an achievable capacity gain of more than 30%.

Migration Form 2g to 3g

...Migration from 2G to 3G - Options: Evolution of Mobile Technologies: The Migration Path This is a brief overview of what has been already done and possible expected migration path of mobile operators. At the 2G phase, there were three major dominant systems in market: a) GSM operating in 900, 1800 and 1900MHz band, b) TDMA operating in 800MHz, 1900MHz and 850MHz (North America), and c) CDMA (IS-95) operating in 1900 and 800MHz band. 2G systems offered enhanced voice services and improved capacity to its customers. With the growing demand in mobile services and the need to connect corporate networks for data communications, an intermediate generation (2.5G) of technologies were developed: GPRS and EDGE (both in the GSM family), and cdma2000 1X-RTT. While migrating from 2G to 2.5G, operators made decisions based on their future planning and business interests targeting third generation (3G) networks. From 2G to 2.5G, GSM operators migrated to GPRS and EDGE systems with some of the TDMA operators also migrating to GSM/GPRS systems (see figure 1). Among them * Vodafone is the largest player with a global foot print in offering GSM/GPRS ser-vices. * Prominent TDMA operators in the United States include AT&T Wireless and Cingular Wireless. * Another major operator includes T-Mobile-USA, offering GSM/GPRS services. * In India, Bharti Cellular (AirTel), IDEA Cellular, Hutchison are some of the GPRS operators whose GPRS networks are in......

3g Technology

...3G, short for third Generation, is a term used to represent the 3rd generation of mobile telecommunications technology. Also called Tri-Band 3G. This is a set of standards used for mobile devices and mobile telecommunication services and networks that comply with the International Mobile Telecommunications-2000 (IMT-2000) specifications by the International Telecommunication Union.[1] 3G finds application in wireless voice telephony, mobile Internet access, fixed wireless Internet access, video calls and mobile TV. Several telecommunications companies market wireless mobile Internet services as 3G, indicating that the advertised service is provided over a 3G wireless network. Services advertised as 3G are required to meet IMT-2000 technical standards, including standards for reliability and speed (data transfer rates). To meet the IMT-2000 standards, a system is required to provide peak data rates of at least 200 kbit/s (about 0.2 Mbit/s). However, many services advertised as 3G provide higher speed than the minimum technical requirements for a 3G service. Recent 3G releases, often denoted 3.5G and 3.75G, also provide mobile broadband access of several Mbit/s to smartphones and mobile modems in laptop computers. The following standards are typically branded 3G: the UMTS system, first offered in 2001, standardized by 3GPP, used primarily in Europe, Japan, China (however with a different radio interface) and other regions predominated by GSM 2G system infrastructure.

3g Historically

...generations. 0G was the invention of the mobile telephone without networks, where callers had to connect to a base station and operator. In 1979 and 80, 1G came out, where the cellular radios (as we engineers called them) were first connected to networks of stations (called cells). The 2G networks were the first ones where consumers became aware of new capabilities and started buying the technology heavily. This was during the late 90s and into the early 2000s. These were the first phones with the PHS, CDMA, GSM, mail, Cameras, and other options. 3G is the network expansion which allowed direct internet connections, Wideband data access, simultaneous voice, data, music, and telephone, plus network based apps all rolled into one. 3G is the network which allows you to use the cell phone as a credit card. 4G is a network in the planning stages, although some companies say they are implementing parts of the 4G net now. 4G includes a network specification (engineer talk for basic requirement), for 100 megabit to 1 gigabit data transfer rates while highly mobile worldwide. It also includes high quality of service requirements for multimedia support (real time audio, high speed data, HDTV video content, mobile TV, etc). 4G is coming, but is not here yet, because the specs are still being worked over at the ITU (Intenational Telecom Union) in Geneva.  A 3G/4G network is one where the network meets all the 3G ITU Specifications, and also has upgraded to meet the 4g......

3g Network in Pakistan

...3G Technology 3G is the next generation of technology which has revolutionized the telecommunication industry. Apart from increasing the speed of communication, the objective of this technology is to provide various value added services like  video calling, live streaming, mobile internet access, IPTV, etc on the mobile phones. These services are possible because the 3G spectrum provides the necessary bandwidth.   Technically speaking 3G is a network protocol which refers to the generations of mobile phones and telecommunication equipments which are compatible with the International Mobile Telecommunications-2000 (IMT-2000) standards stated by International Telecommunication Union (ITU). The basic requirement for compiling to IMT-2000 standards is that the technology should provide peak data rates of at least 200 Kbit/s. It’s worth mentioning that speed isn’t the only criteria for deciding whether the network protocol is 3G or not. 3G isn’t just any high speed network but a protocol which has its own standards defined under IMT-2000 by ITU.   3G Technology is designed for multimedia communication. It provides services like higher data transfer rates. One of its key visions is to provide seamless global roaming, enabling users to move across borders while using the same number and handset. According to ITU it is expected that IMT-2000 will provide higher transmission rates: a minimum speed of 2Mbit/s for stationary or walking users, and 348kbit/s in a moving......

Technology of 3g

...3g or third generation mobile technology refers to the standards set by International Telecommunication Units (ITU). This technology allows mobile operators to offer more options to users including mobile broadband. 3G facilitates devices like mobile phones and mobile dongles to deliver broadband speed internet. Most new top of the range mobile phones are 3G enabled, making it easy to check emails and browse the web on the go. Internet use via mobile phones has been slow to take off but mobile broadband via dongles, has taken off extremely fast. Mobile broadband allows customers to browse the internet, email and download files, music and video clips from their laptops and PCs wherever there’s mobile coverage. 3G technology is made possible by two complementary technologies, HSDPA and HSUPA (high speeds downloads and upload packet access, respectively). These technologies enable mobile broadband users to access of up to 7.2 Mb downloads and uploads with speeds of up to 1.76 Mb via a mobile dongle, USB modem or data card which they plug into the USB port of their laptop or PC. 3G can offer speed up to 7.2 Mb as it uses the air waves more efficiently, than its predecessors such as 2G and GPRS which offered limited internet connectivity. The initial foundation of 3G can be traced back to 1970s when Luigi Galvani investigated the nature and effects of electrophysiology, and began experiments with muscular stimulation by electrical means.

Abis Optimization

...The value of Abis optimization PUBLIC 2011-11-10 Issue 39 of Huawei Communicate Page 1 of 6 Not So Worthy: Abis optimization With the rapid development of mobile services, there had been increasing pressure and demands on mobile backhaul bandwidth, especially in terms of 3G service provision. Abis optimization can ameliorate this situation to some extent by enhancing transport efficiency, but the total value it generates remains in question. Theory of Abis optimization As 3G traffic continues to grow, operators must tackle the issue of higher bandwidth requirements. This has resulted in huge investments for network capacity expansion. With such high demands for bandwidth optimization, various technologies have been developed and applied to mobile backhaul networks—Abis is one of the many options available. Voice services remain a dominant commercial interest for mobile operators. Since GSM system differs from 3G UMTS systems in terms of voice service processing, Abis optimization technology has various effects. GSM system utilizes full-rate (FR) codes to process voice services, and occupies transmission bandwidth even during the mute period of the communication process. Abis optimization technology is designed to eliminate mute frames through its BTS interface. It can also multiply the unused timeslots. The mute frames are then recovered before the BSC, enhancing 2G service transport efficiency by an average of 60%, and even 80% in best case scenarios. On...
