Key User Features of GPRS The General Packet Radio Service (GPRS) is a new nonvoice value added service that allows information to be sent and received across a mobile telephone network. It supplements today’s Circuit Switched Data and Short Message Service. GPRS is NOT related to GPS (the Global Positioning System), a similar acronym that is often used in mobile contexts. GPRS has several unique features which can be summarized as: SPEED Theoretical maximum speeds of up to 171.2 kilobits per second (kbps) are achievable with GPRS using all eight timeslots at the same time. This is about three times as fast as the data transmission speeds possible over today’s fixed telecommunications networks and ten times as fast as current Circuit Switched Data services on GSM networks. By allowing information to be transmitted more quickly, immediately and efficiently across the mobile network, GPRS may well be a relatively less costly mobile data service compared to SMS and Circuit Switched Data. IMMEDIACY GPRS facilitates instant connections whereby information can be sent or received immediately as the need arises, subject to radio coverage. No dial-up modem connection is necessary. This is why GPRS users are sometimes referred to be as being “always connected”. Immediacy is one of the advantages of GPRS (and SMS) when compared to Circuit Switched Data. High immediacy is a very important feature for time critical applications such as remote credit card authorization where it would be unacceptable to keep the customer waiting for even thirty extra seconds. NEW APPLICATIONS, BETTER APPLICATIONS GPRS facilitates several new applications that have not previously been available over GSM networks due to the limitations in speed of Circuit Switched Data (9.6 kbps) and message length of the Short Message Service (160 characters). GPRS will fully enable the Internet applications you are used to on your desktop from web browsing to chat over the mobile network. Other new applications for GPRS, profiled later, include file transfer and home automation- the ability to remotely access and control in-house appliances and machines. SERVICE ACCESS To use GPRS, users specifically need: · a mobile phone or terminal that supports GPRS · a subscription to a mobile telephone network that supports GPRS · use of GPRS must be enabled for that user. Automatic access to the GPRS may be allowed by some mobile network operators, others will require a specific opt-in Mobile Lifestreams Limited www.mobileGPRS.com Page 9 · knowledge of how to send and/ or receive GPRS information using their specific model of mobile phone, including software and hardware configuration (this creates a customer service requirement) · a destination to send or receive information through GPRS. Whereas with SMS this was often another mobile phone, in the case of GPRS, it is likely to be an Internet address, since GPRS is designed to make the Internet fully available to mobile users for the first time. From day one, GPRS users can access any web page or other Internet applications- providing an immediate critical mass of uses. Having looked at the key user features of GPRS, lets look at the key features from a network operator perspective. 2. Key Network Features of GPRS PACKET SWITCHING GPRS involves overlaying a packet based air interface on the existing circuit switched GSM network. This gives the user an option to use a packet-based data service. To supplement a circuit switched network architecture with packet switching is quite a major upgrade.

E.D.T.,Vol.3(1):23-28 (January-February, 2014) ISSN: 2319 – 7293 EVOLUTION OF EDGE TECHNOLOGY IN MOBILE COMMUNICATIONS FOR GSM MODULE WITH IS-136- A REVIEW ARTICLE G S AJAY KUMAR REDDY1*, G KEERTHY1, P ARAVIND1*, Ch HARSHA VARDAHN1* 1Assistant System Manager, Tata Consultancy Services, Bengaluru Section, INDIA 1* Graduating in Department of Electronics and Communication Engineering, Lakireddy Bali Reddy Autonomous Engineering College, Mylavaram– 521 230, Krishna, A.P., India. Abstract Today’s fast growing world needs fast communication, either it may be voice or data .This calls for a new technology which is faster than all existing technologies in mobile communication and hence can replace technologies like GPRS .Enhanced Data for Global Evolution (EDGE) is such a technology .EDGE is a member of global system for mobile communications (GSM).In short EDGE is a technology which enhances data rates for mobile communications. EDGE not only enhances data rates but also intended for efficient spectrum utilization which it has passed successfully. This paper is intended for explaining how theoretical data rates of 384 kbps is possible with EDGE technique. And how enhanced data for global evolution (EDGE) can play an important role in the evolution toward wideband code division multiple access (WCDMA) and this paper also includes brief details on EDGE and modulation scheme used for EDGE. It can be introduced in two ways: (1) as a packet-switched enhancement for general packet radio service (GPRS), known as enhanced GPRS or EGPRS, and (2) as a circuit-switched data enhancement called enhanced circuit-switched data (ECSD).

  • The Evolution of Cellular Data: on the Road to 3G Published by Intel
    The Evolution of Cellular Data: On the Road to 3G Published by Intel Corporation. Peter Rysavy, Rysavy Research Copyright 1999. All rights reserved. Introduction Wireless phone use is taking off around the world. Many of us would no longer know how to cope without our cellphones. Always being connected offers us flexibility in our lifestyles, makes us more productive in our jobs, and makes us feel more secure. So far, voice has been the primary wireless application. But with the Internet continuing to influence an increasing proportion of our daily lives, and more of our work being away from the office, it is inevitable that the demand for wireless data is going to ignite. Already, in those countries that have cellular-data services readily available, the number of cellular subscribers taking advantage of data has reached significant proportions. We want wireless Internet, we want our organizational data from anywhere, and we want it now. But to move forward, the question is whether current cellular-data services are sufficient, or whether the networks need to deliver greater capabilities. The fact is that with proper application configuration, use of middleware, and new wireless- optimized protocols, today’s cellular-data can offer tremendous productivity enhancements. But for those potential users who have stood on the sidelines, subsequent generations of cellular data should overcome all of their objections. These new services will roll out both as enhancements to existing second- generation cellular networks, and an entirely new third generation of cellular technology. Our job here is to describe this road to the third generation (3G), as well as to show you how these services will allow new applications never before possible.

  • High Speed Circuit Switched Data (HSCSD)
    High Speed Circuit Switched Data (HSCSD) High Speed Circuit Switched Data (HSCSD) is an enhancement in the data rate of circuit switched data in a GSM network. HSCSD uses two techniques to increase the data rate. First, HSCSD makes it possible to use more than one time slot. GSM uses time division multiple access (TDMA). Each radio channel is divided in eight time slots. Each time slot is allocated to a different user. This makes it possible to serve eight customers on one radio channel. HSCSD makes it possible to allocate more than one time slot to a user. The second technique used by HSCSD is that the error correction can be adapted to the quality of the radio channel. A standard slot can carry 9.6 kbps. HSCSD makes it possible to increase this to 14.4 kbps. The quality of the radio channel must be good enough to do so. The maximum data rate of a HSCSD configuration with 14.4-kbps channel coding is 115.2 kbps, if all eight time slots are allocated to the same user. In practice, is the number of time slots allocated to a user limited to three, limiting the data rate to 43.2 kbps. Another point is that the core network is based on circuit switched data with data channels of 64 kbps. The main benefit of HSCSD compared to other data enhancements introduced later is that it is an inexpensive way to implement higher data rates in GSM networks. There modifications to be made are relatively small. A new functionality is introduced at the network and MS to provide the functions of combining and splitting the data into separate data streams which will then be transferred via n channels at the radio interface, where n = 1, 2, 3, ..

  • Migration to 3G Technology Standards: a Comparison of Selected Countries by Richard Nunno, International Bureau, FCC September 2003
    Migration to 3G Technology Standards: A Comparison of Selected Countries By Richard Nunno, International Bureau, FCC September 2003 For over a decade, the International Telecommunication Union (ITU) has been supporting the international effort to develop an advanced third-generation (3G) mobile telecommunications service that has a higher bandwidth than previous and existing mobile services and that subscribers can seamlessly use across international borders (known as global roaming). To that end, the ITU has identified spectrum and developed technical standards for International Mobile Telecommunications 2000 (IMT-2000), the official name for 3G services. The ITU’s World Administrative Radiocommunication Conference (WARC) in 1992 and World Radiocommunication Conference (WRC) in 2000 identified several bands of spectrum that could be used for 3G services. The mobile telecommunications industry has started delivering 3G services that provide broadband applications including voice, data, and video. As defined by the ITU, 3G signal transmission rates must be able to reach 2 megabits per second (Mbps) or higher for indoor (low mobility) wireless applications (more than 35 times faster than today’s 56 kilobits per second (kbps) dial-up PC modems). 3G rates may be slower (384 kbps) for pedestrian traffic, and 144 kbps for high mobility (vehicular) traffic.1 How each country is implementing 3G systems depends on a number of factors, such as the country’s 3G spectrum allocations, the standards it adopts for 3G (if it adopts any standards vs. letting the marketplace make the decision), and the country’s current mobile telephony system configuration. Because a great deal of information and analysis is already available on the spectrum-related issues surrounding 3G implementation, this report focuses only on the technology standards issues pertaining to 3G.
