Certain modern two-way radio systems may have full-duplex telephone capability. As such, the channel of information and messages in a mobile radio is variable. Used to be known as radiophone, the earlier versions of the mobile radio, were one-way communication systems used for broadcast. Contemporary mobile radio systems can have as much as a hundred channels and may be controlled by microprocessors.

These types require the use of software to encode channels and operate their integrated functions. The mobile radio, also known as a two-way radio system, allows the exchange of messages only with other mobile radios through push-to-talk PTT functions.

A mobile radio also features wireless transceivers, making mobile radios portable. Mobile radio systems may be used for communications in aircraft, ships, automobiles, and other vehicles.

The power supply on which mobile radios run depend on the type of vehicle these are mounted on. A mobile radio system is composed of a transceiver and microphone with a push-to-talk key. It has an antenna that links to the transceiver. Since most types of mobile radio are used in moving vehicles, where the surrounding noise can be loud, some mobile radio types come with an external speaker. Other models have headsets and microphones with noise-reduction capabilities.

How does a mobile radio work? Military planners need to maintain a continuing awareness of the difference between what is possible technically and what is available in the market to meet military needs. Because military requirements often exceed those of the commercial market, opportunities for the DOD to use commercial products depend on equipment details, which are reflected in standards. Such details might be of little initial interest to consumers. Yet the defense community is often ahead of industry in recognizing features that will eventually be important to all users; if these needs are not addressed in the standards-setting processes then they might have to be met later in commercial settings at great cost, both financially and in terms of network performance.

An example is the poor state of network security in analog cellular systems, an issue not considered in the initial design process. Newer digital systems help alleviate this problem, but adding security features to older equipment remains an expensive and difficult challenge.

The military, by contrast, always plans for system security in advance. Standards also influence whether "hooks" or interfaces are designed into commercial technologies to enable modifications that would meet specialized military needs. By participating in the standards process, government agencies will make it possible to embed standard devices in military-specific system architectures and generally promote a capability for cost-effective systems integration.

Effective participation will be constrained by the rules governing standards organizations and by the abilities of DOD management and participating individuals to influence technical decisions and political processes. They will need to understand how standards for wireless communications are established, a complex process that has influenced the very different evolutionary paths of wireless technologies in the United States, Europe, and Japan.

In addition, the DOD could benefit from the analysis, simulation, and laboratory testing of candidate technologies to support defense interests in the establishment of specific standards. These activities could reveal the limits of some technologies that would not be apparent in more benign commercial settings but are likely to be of long-term significance to consumers.

Participation in standards creation could ultimately prove to be more cost-effective than commissioning equipment explicitly designed to meet military needs. The DOD should pursue a vigorous process of technology demonstration and testing prior to development and procurement. In particular, the focus should be on system concepts based on commercial technologies and specialized military enhancements.

As the defense budget is reduced, less money will be available for major procurements. Nevertheless, an inventory of advanced technologies can be maintained and deployed as needed if military equipment is adapted whenever possible from commercial technologies. Examples of this strategy include the Condor project, in which DOD is supporting the development of a cryptography module on top of the cellular telephony system, and the Army's plans for the digitized battlefield.

The Condor project is focusing on core noncommercial technologies such as on-the-move, high-bandwidth, phased-array antenna technology. The Army's digitized battlefield network will include switches, routers, and hubs based on commercially available technology. The Army is not building its own ATM switches, which are widely available in the private sector, but instead is developing high-speed encryptors and decryptors that are compatible with commercial switches.

These technologies need to be developed by the DOD. For all other elements of wireless systems, new commercial developments need to be tested and evaluated on a continuing basis in military exercises to determine and verify their suitability for military use.

Resources available to support this approach include the federal defense laboratories, which can provide a critical bridge between the military's operational needs and private technology development, and the defense industry, which is well equipped to collaborate in the development of prototype military-specific equipment.

In addition, both the DOD and industry will continue to rely heavily on U. A mechanism is needed to help integrate the requirements of these varying systems and find a common architecture that would cost-effectively support the majority of those requirements.

In the past the military has focused on one radio subsystem at a time, with the result that interoperability has been minimal. The vision of the future calls for the development of an overall system concept with a standard set of multimedia protocols and waveforms to assure interoperability at all echelons, with individual radios specified and procured to work within this architecture.

The DOD should plan a new approach to procurement that will identify now commercial infrastructure systems and subscriber equipment can best be used for military purposes and how to download commercial equipment in the most productive way.

The DOD needs to develop models to analyze how best to use commercial systems and equipment.

For example, a planning system could be created to keep track of commercial communications infrastructure and service access points within a given geographical region. Such a system needs to be comprehensive, monitoring telephony, data, microwave, satellite, and fiber-optic services. This would help to curtail the damage to life and property. As Dr. India has the best of resources and technical minds available, through which it can move ahead of its other developed counterparts.

The railway accidents over the past decade cannot be neglected and the unfortunate events cannot be entirely reasoned as an event occurring out of chance. Trains are merely machines running on railway tracks and they cannot think of how to avoid accidents on their own.

It is up to the human beings to design and use an efficient system which can help the train driver and the station master to know about the possibility of any untoward hazard beforehand by developing effective communication between the concerned officials.

The necessity of mobile train radio communication in india 1. Presently, India has the third largest railway network in the world, covering a total length of around 65, Kilometers. More and more passengers are using Railways as a means of travel.

Millions of tones of goods are now being transported by trains. Indian Railways transport billion passengers and over million tones of goods annually.

As the world is getting technologically advanced, more complications have set in regarding safety and security of passengers. The report of the High Level Safety Review Committee of estimates that almost 15, number of persons gets killed every year in train accidents. Apart from this, security in trains is also a major concern. Considering all these necessities, the need of the hour is to develop an effective and a technologically advanced communication system in the Indian Railways.

It ensures safety of passengers by providing effective communication between Driver and Control Room. The MTRC system can be used to warn the drivers beforehand of the running trains as well as the concerned officials. In case of any security problem, concerned staff can immediately intimate the concerned security establishment. If any accident takes place, the MTRC system will facilitate better post-disaster management. In the present day, Railways need not just effective voice transmission, but also have the capability to analyze all the technical data to arrive at the correct decision to be taken on the spot.

Signaling and Telecommunication in the Indian Railways network Effective signaling is necessary for the proper functioning of railways. The Signaling and Telecommunication Department of the Indian Railways plays as integral role to ensure glitch-free signaling operations. In , the Performance Audit conducted under the Special Railway Safety Fund reviewed the progress in meeting the aims which were raised in the Corporate Safety Plan initiated in
