Overview The GSM system utilises new technologies efficiently. A collection of innovative technological features demonstrates the engineering force behind the system. The use of certain technological features is motivated by the benefit that is offered. The variety of the level of technologies is wide; from small details hidden deep in the system to revolutionary new concepts at the top level of the system, visible to all users. The world is becoming digitalised. Analogue systems in many fields
passive components of GSM base station such as transceiver (TRx), power amplifiers (PA), combiners, duplexers, antennas, alarm extension system, control function, base-band receiver (BBxx), signal DSP, main distribution board, rectifier and Environmental Monitoring Unit (EMU) are discussed in [20]. Other components discussed are DC ventilation system, air conditional, generators, BTS cabinet, transmission rack, microwave antenna, aviation light, and optical fibre/coaxial cable. GSM Transmitter Measurement
per second and even more, which can make data transfer seamless and downloads relatively fast. Unlike GSM, UMTS is mainly based on CDMA (Code Division Multiple Access) scheme and now combines it with TDMA. The four biggest differences are: 1. UMTS has faster data transfer rates than GSM. 2. GSM is 2G and 2.5G while UMTS is already 3G. 3. GSM is a rather old technology while UMTS is newer. 4. GSM is typically based on TDMA while UMTS is mainly CDMA-based.
Strength: In 1993, the geographic coverage became more complete, smaller equipment became available, and consumers started to utilize the service up to its full potential. Strength: GSM technology was a major departure from the previous system and the WESTEL had selected Ericsson to build its GSM system. Strength: WESTEL had a strong emphasis on quality and received the ISO 9001 certificate. Later it was dominated and selected for the Hungarian National Quality Prize, and the
Foundation • Bharti Realty Bharti Airtel Ltd. has been structured into three individual strategic business units (SBU’s) Mobile Services, Airtel Telemedia Services & Enterprise Services. The mobile business provides mobile & fixed wireless services using GSM technology across 22 telecom circles while the Airtel Telemedia Services business offers broadband & telephone services in 95 cities and has recently launched a Direct-to-Home (DTH) service, Airtel digital TV. The company provides end-to-end data and
and trains - (nearly) everything is possible. Especially in business WAP seems to be the "star performer" as to corporate communication solutions. Trends in WAP Customers willing to make use of these new possibilities need a WAP phone. This is a GSM mobile phone with incorporated modem and WAP browser. The data is transmitted with the usual transmission rate of 9.6 kBit/s. As to the consumers' interest in WAP there are still controversies. Mobile phones recorded in the UK very high sales rates
especially from businessmen who frequently travel. Linda Stern suggests in Newsweek to global travelers that they should “buy your phone and service from T-Mobile, AT&T or Cingular, the only three U.S. companies to use the internationally dominant GSM (Global System for Mobile communication).” Depending on the service provider, one may or may not get coverage in other countries. For example, Verizon customers enjoy phones that work in Latin America, while Cingular customers have coverage in Europe
carriers and was first developed for 900 MHz (GSM 900) band but then extended to 1800 MHz band (GSM 1800). GSM was originally designed as a voice oriented network but later on some new features have been aggregated to support data transmission. General Packet Radio Services (GPRS) and Enhanced Data-rates for Global Evolution (EDGE) showed up accordingly to fulfill market demands in terms of voice reliability and high transmission data rates. As of today GSM is still dominant in current mobile communication
is one of the newest in the region. The country was devoid of cellular telephony until 1999 when the Ministry of Communications and Technology (MoC) granted national PTO the Syrian Telecommunications Establishment (STE) permission to begin a trial GSM service in the major cities of Damascus, Aleppo and Latakia. In conjunction with Siemens and Ericsson, which also partly financed the project, STE installed ten base stations in the capital and six in Aleppo and Latakia. The pilot was launched in February
NOKIA- The Creation of New Markets By the end of 2003, Nokia was the clear market leader in the mobile phone industry in terms of sales and profitability. It was ahead of giant companies like Motorola, Ericsson, Siemens, Samsung, and other worthy competitors. Since the early 1990s, Nokia's Strategic Intent was to build distinctive competency in product innovation, rapid response, and global brand management. Its strategic intent required rapid growth in the core businesses of mobile phones and
A single frequency radio wave does not transmit any information. In order for information to be transferred, the frequency needs to vary in time. The range of frequencies that a single channel can occupy is what is known as its bandwidth. In order to allow for multiple calls to be handled by a single base station, multiplexing techniques are used which are ways of combining multiple signals. The four main techniques include: frequency division multiple access (FDMA), time division multiple access
an application in wireless voice telephone, mobile internet access, fixed wireless internet access, video calls and mobile TV. 3G show all collection of technology to facilitate a higher speed for data transfer faster than earlier version. CDMA and GSM were primary category of phone technology. 3G network are form by these two different technology that had been elaborated. 3G smartphone can conduct high speed data transfer rate by accessing 3G cell phone technology and its mean browsing, streaming

G in 1G, 2G, 3G and 4G stands for the “Generation” of the mobile network. Today, mobile operators have started offering 4G services a higher number before the ‘G’ means more power to send out and receive more information and therefore the ability to achieve a higher efficiency through the wireless network. During the time of 1G, radio signals were transmitted in ‘Analogue’ form. 2G networks on the other hand, were based on narrow band digital networks. The 3rd generation of mobile networks has become
01. Introduction to Mobile Communication Today mobile communication has become the backbone of the society. All the mobile system technologies have improved the way of living and it is one of the fastest growing communication medium in the world (Goldsmith, 2004). In 1960 Bell Laboratory was introduced the cellular concept, with the development of the newer concept and the better technology cellular phones getting more popular in worldwide (Mitra, 2009). According to the (GSMA, 2014) report mentioned
In the world today there are many cellular technologies to choose from along with companies that provide that provide services to these technologies. What makes matters worse are the many choices that we are faced with, in just choosing what mobile phone too pick. The questions are, what are these technologies, which cellular provider do I pick and how do I decide on a phone? More importantly, is there some magic combination that will give me the best service wherever I am? Nowadays we use our phones
Mobile phones act as a ‘Window to the World’ for rural India. They provide the rural communities a means to connect to the outside world and to each other. But it took a very long time for mobile phones to enter the rural market. Let’s look at the story from the start. When land phones first came into rural India, there used to be a single phone for a whole village which acted as the sole point for communication. People used to go there and wait for calls from their loved ones at prior appointed
Cell phones are used all around the world on a daily basis. From America to China, millions of users rely on cell phones in their daily lives. While cell phones have multiple uses to help individuals with their daily needs, this particular device also comes with many risks. While the benefits of owning a cell phone are great, cell phones can cause tremendous damage not only to your body, social life, but affect your education as well. If individuals begin to spend time away from their cell phones
