TRAINING AND PROJECTS

Manpower requirement has been the most motivating factor for development and implementation of projects. It is not possible to to expect from recruits that much expertise as is needed for the development of a new project immediately assigned to them. Most of our recruits are freshers and they do not possess the level of expertise to carry out an image processing project or web based automation project. Our traning division provides training not only to freshly recruited candidates but also to the final year Engineering/MCA students aspiring to build up a career in this direction. We provide training on various tools and technologies of JAVA, J2ME, Oracle, Visual Studio .NET, Seagate Crystal Reports, GSM, CDMA, Telecom protocol, RF, Drive test, BTS Commissioning, Maintenance etc.

Java technology is an object-oriented, platform-independent, multithreaded programming environment. It is the foundation for Web and networked services, applications, platform-independent desktops, robotics, and other embedded devices. Enabling Business from End to End - Java technology offers a single, unifying programming model that can connect all elements of a business infrastructure. For developers, Java technology allows them to write software on one platform and run it on practically any other platform. It lets them create multi-threaded programs that run within Web browsers and Web services. Also, they can combine reusable Java objects to quickly create unique and highly customized server-side applications, such as online forums, stores, polls, HTML forms processing, and secure transactions. And of course, there's a support community of four million fellow developers, thousands of independent developer web sites, hundreds of providers that support Java developers, and the Java Community Process. For business, Java technology represents choice, performance, efficiency, and flexibility. The Enterprise Java platform serves as an end-to-end infrastructure that gives IT managers an extremely wide variety of compatible business logic applications, independent of their application server or portal server vendor - whether it is BEA, IBM, Oracle, or Sun. It significantly extends their reach and interactivity among employees, customers, and partners. Just as important, IT managers know there is a global ecosystem of Java developers, support engineers, and knowledge bases to reduce the risk and time to deployment as well as the ongoing cost of ownership and maintenance. For consumers, Java technology is the first software technology that simply works without a struggle. Consumers are delighted to see applications run reliably and compatibly on such an incredible array of network products - from PCs, game players, and mobile phones to home appliances and automotive electronics. The Java brand has come to represent applications that are lively and interactive. A growing voice among consumers all over the globe actively prefers Java Powered applications and products. Java technology has become a complete software ecosystem that represents different values to different types of consumer and business users. It offers developers a choice of three Java platform editions depending on the need:
The Java™ language, and the ever-growing Java platform, have revolutionized programming. The goal of our training is to introduce you to the Java syntax you're most likely to encounter professionally, and to expose you to idioms that will help you avoid trouble. our trainee programmers are guided by our experts to master the essentials Java programming, including the OOP paradigm and how it applies to Java programming, Java language syntax and use, creating objects and adding behaviour, working with collections, handling errors, and tips for writing better code.
Much of the syntax of Java is the same as C and C++. One major difference is that Java does not have pointers. However, the biggest difference is that you must write object oriented code in Java. Procedural pieces of code can only be embedded in objects. In the following we assume that the reader has some familiarity with a programming language. In particular, some familiarity with the syntax of C/C++ is useful. Java is an object-oriented programming language with a built-in application programming interface (API) that can handle graphics and user interfaces and that can be used to create applications or applets. Because of its rich set of API's, similar to Macintosh and Windows, and its platform independence, Java can also be thought of as a platform in itself. Java also has standard libraries for doing mathematics. In Java we distinguish between applications, which are programs that perform the same functions as those written in other programming languages, and applets, which are programs that can be embedded in a Web page and accessed over the Internet. Our initial focus will be on writing applications. When a program is compiled, a byte code is produced that can be read and executed by any platform that can run Java.
 
Remote method invocation allows applications to call object methods located remotely, sharing resources and processing load across systems. Unlike other systems for remote execution which require that only simple data types or defined structures be passed to and from methods, RMI allows any Java object type to be used - even if the client or server has never encountered it before. RMI allows both client and server to dynamically load new object types as required. In this article, you'll learn more about RMI.
To develop applications using wireless Java technology, you'll need to assimilate information from several fields. You'll need to understand something about wireless communications technology, the business of wireless communications, and a lot about the Java platform. Our exquisite training on wireless JAVA technology will assist you in building up sms automation projects, mobile applications and remote sensing tools. Wireless communications is a huge field, encompassing everything from radio and television broadcasting through pagers, mobile phones, and satellite communications. The field of mobile phones is expanding very fast at the same time that standards and protocols are being adopted, used, updated, and sometimes discarded. The other rapidly expanding part of the wireless world is that of wireless local area networks (LANs). Driven by widespread acceptance of the IEEE 802.11 standard, wireless local networking for computers and other devices is spreading rapidly.
Although wireless may seem like a special case, it is actually more intuitive and more natural than wired networking. Some day soon the need to plug a laptop into a network physically will seem quaint and antiquated. The notion that you could walk into a room with your cell phone and have it unable to interact with other devices in the room will seem unbelievably primitive. The future will reveal that wired networks are the special case. Although wireless may seem like a special case, it is actually more intuitive and more natural than wired networking.

The notion that you could walk into a room with your cell phone and have it unable to interact with other devices in the room will seem unbelievably primitive. The future will reveal that wired networks are the special case. Wide area wireless devices operate effectively over a much greater area. A pager or mobile phone is a good example; you can talk on your mobile phone to any other phone on the planet. These devices' greater range relies on a trick, however: a more elaborate land-based network. A mobile phone doesn't have that much more radio power than a radio control toy. What it does have is a network of carefully placed radio antennas (cell towers); the phone can continue to operate as long as it is within range of at least one tower. The mobile phone device receives service from a wireless carrier , a company that operates the land-based network.

The .NET Framework is Microsoft's managed code programming model for building applications on Windows clients, servers, and mobile or embedded devices. Developers use .NET to build applications of many types: Web applications, server applications, smart client applications, console applications, database applications, and more.NET is the Microsoft Web services strategy to connect information, people, systems, and devices through software. Integrated across the Microsoft platform, .NET technology provides the ability to quickly build, deploy, manage, and use connected, security-enhanced solutions with Web services. .NET-connected solutions enable businesses to integrate their systems more rapidly and in a more agile manner and help them realize the promise of information anytime, anywhere, on any device.

To support this variety, the .NET Framework includes a broad set of supporting class libraries, including: Windows Presentation Foundation (WPF), for visually stunning user experiences on Windows clients; Windows Communication Foundation (WCF), enabling fast and flexible communications among applications across your enterprise; Windows Workflow Foundation (WF), allowing developers to build workflows into any application; ASP.NET , for high-performance and interactive Web-based applications; Libraries for handling XML, data, IO, cryptography, text-to-speech, and more.

TRAINING ON GSM , CDMA, RF, DRIVE TEST, TELECOM PROTOCOL

In cellular service there are two main competing network technologies: Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA). Cellular carriers including Sprint PCS , Cingular Wireless, Verizon and T-Mobile use one or the other. Understanding the difference between GSM and CDMA will allow you to choose a carrier that uses the preferable network technology for your needs. The GSM Association is an international organization founded in 1987, dedicated to providing, developing, and overseeing the worldwide wireless standard of GSM.CDMA, a proprietary standard designed by Qualcomm in the United States, has been the dominant network standard for North America and parts of Asia. However, GSM networks continue to make inroads in the United States, as CDMA networks make progress in other parts of the world. There are camps on both sides that firmly believe either GSM or CDMA architecture is superior to the other. That said, to the non-invested consumer who simply wants bottom line information to make a choice, the following considerations may be helpful.

That said, to the non-invested consumer who simply wants bottom line information to make a choice, the following considerations may be helpful.
Coverage : The most important factor is getting service in the areas you will be using your phone. Upon viewing competitors' coverage maps you may discover that only GSM or CDMA carriers offer cellular service in your area. If so, there is no decision to be made, but most people will find that they do have a choice.
Data Transfer Speed : With the advent of cellular phones doing double and triple duty as streaming video devices, podcast receivers and email devices, speed is important to those who use the phone for more than making calls. CDMA has been traditionally faster than GSM, though both technologies continue to rapidly leapfrog along this path. Both boast "3G" standards, or 3rd generation technologies.
Mobile communication is the fastest growing field in the telecommunications industry. During interaction with students, we discuss the history, present state, and future of cellular radio networks. The cellular radio network system facilitates mobility in communication. Systems achieve mobility by transmitting data via radio waves. The following are some examples of mobile communication systems currently in use.
Paging A simple and inexpensive form of mobile communication. An antenna or satellite broadcasts short messages to subscribers. Receivers are usually devices such as beepers, which display messages on a small screen. Transmission of data is one-way. Paging systems are designed to provide reliable communication to subscribers wherever they are. This necessitates high-powered transmitters and low data rates for maximum coverage of each transmitter's designated area.
Communication Satellites Satellites consist of large transponders that listen to a particular radio frequency, amplify the signal, and then rebroadcast it at another frequency. They are inherently broadcast devices. A drawback of satellites is that they have quite a large propagation delay due to the distances traveled by radio waves.
Cellular Radio Networks Cellular networks are divided up into cells, each cell being serviced by one or more radio transceivers (transmitter/receiver). Communication in a cellular network is full duplex, where communication is attained by sending and receiving messages on two different frequencies - frequency division duplexing (FDD). The reason for the cellular topology of the network is to enable frequency reuse. Cells, a certain distance apart, can reuse the same frequencies, which ensures the efficient usage of limited radio resources.
Personal Handyphone The Personal Handyphone System (PHS) is used in Japan. It is similar to cellular networks, however phones can also communicate directly with one another when in range. This is an advantage over cellular phones, which can only communicate with one another via base station transceivers. This system is very popular within heavily populated metropolitan areas.
Mobile Radio Mobile radio is in many ways the predecessor to the cellular radio network. It is mostly analogue, and makes use of single frequencies for sending and receiving signals. Communication is half-duplex, and a button must be pressed to switch modes. They are most commonly used for emergency services, the transport sector, and the security industry
Communication networks make use of protocols to facilitate communication between different entities within a network. A communication protocol is a set of messages and rules that correspond to messages communicated between two or more entities on a network. A network entity usually makes use of a whole set of such protocols, which are organized into a layered stack. The GSM protocol stacks correspond to the OSI reference model; layers 1 and 2 of the GSM model correspond to the physical and link layers as defined by the OSI model. The physical layer specifies how data is transmitted from one entity to another across the physical transport medium. The physical transport medium between the MS and BST is the ether (air). Data is transmitted across the ether by modulating electromagnetic radio waves. The similarity between the GSM protocol stack and the OSI model ends at the link layer. Layer 3 of the GSM protocol stack does not correspond to the network layer of the OSI model. GSMs layer 3 is composed of 3 parts, which is known as the message or signaling layer. It is used to set up and maintain voice circuits between users of a mobile cellular network. It does this by managing radio resources, information about user whereabouts, and voice circuit information. These operations are all specific to cellular radio networks because other networks do not have to keep track of user whereabouts or movement of users from one cell to another.
The radio link between the MS and the BST over the Um interface makes mobile communication possible. By using the ether as transmission medium, users can gain access to communication networks without being physically connected. Communication over the ether does have its drawbacks. The radio spectrum available for cellular communication purposes is limited. Therefore, the available radio spectrum has to be used efficiently. The cellular configuration of the network is designed with this restriction in mind. The radio resource management protocol's job is to manage radio resources as efficiently as possible by using the cellular configuration. The setup of calls is accomplished through a polling scheme. The protocol uses a control channel that exists permanently between mobile stations and base stations. The control channel is used to send a request for a call setup from base stations to mobile stations. The mobile station continually polls the channel for connection requests. If the mobile station and the necessary radio resources (available communication channel) are available, the protocol sets up a dedicated voice circuit. By using this scheme, voice circuits only exist when necessary, and then get destroyed. The control channel uses a minimal amount of radio frequency, and therefore frequency is conserved by minimizing the existence of voice circuits to the times when they are needed.
