The Communication in the Economic Development of Bangladesh

The Communication in the Economic Development of Bangladesh

Introduction:

One cannot now deny the unavailability of communication for development in the changing global perspective. With the radical change in the perception of development and increased electronic media in the 90s, the role of communication in development has increased tremendously. The term ‘development’ now connotes ‘human development’ or in other words, development of human beings, through creating social and economic opportunities for them and widening human choices to bring changes in their lives. People must be at the center of human development. Development has to be woven around people, not people around the economic development. It has to be the development of the people, by the people, for the people with the role of communication in the economic development of Bangladesh.

Communication in the Economic Development of Bangladesh:

• Communication plays a vital role in advancing economic growth and reducing poverty. A survey of firms carried out in 56 developing countries found that firms that use Communication grow faster, invest more, and are more productive and profitable than those that do not.

• While the transition to well-regulated and competitive service provision is important for increasing Communication access, there is some way to go in this transition. For example, nearly half of countries globally retain monopolies on the service provision of Communication.

• There is a continued need for government and private sector support of initiatives that extend “access” to Communication. The report describes innovative examples of public-private partnerships that can extend access to Communication in rural and remote areas.

Transport Communication:

The role of an efficient transport and communication system is extremely critical for the socio- economic progress of a country. As physical infrastructure is indispensable, a well-knit transport and communication network ensures a well balanced distribution system for the means of production, efficient marketing of produced commodities, maintaining stability of price and rapid industrialization. In the current context of globalization and market economy, there is a critical need for evolving a developed and well knit transport and communication system that should be able to integrate Bangladesh with the international transport and communication network. Realizing this importance, the concerned ministries and their agencies continue to exert their concerted efforts to develop the system. In the Revised Annual Development Programme (RADP) of FY 2004-05 there is an allocation of TK. 4543.77 crore for transport and communication sector.  In FY 2004-05, the contribution of this sector to the GDP at constant prices is about 10.01 percent (provisional). The transport and communication network in Bangladesh has evolved with roads, railway, and water and air transport as well as post telecommunication and information technology.

Transport Communication

Jamuna Multipurpose Bridge Authority (JMBA)

Jamuna Bridge is playing a vital role in road transport system. The Bridge has made the communication between eastern and northern region of the country easier. As a result the producers are getting fair prices of their produces which are encouraging them to produce more. This, in effect, is inducing increased production. Beside, with the establishment of new industries economic activities in the north west zone increased manifold. Therefore there is an increasing trend toll collection. Because of construction of a dual gauge railway across Tangail under Jamuna Rail link project, it was possible to set up a direct railway link between the capital city Dhaka and Rajshahi and Khulna Division. Alongside setting up fail and electricity line gas line has been set up over the bridge.

Bangladesh Road Transport Corporation (BRTC)

BRTC has a rich tradition as an entity. To establish a sound transport system BRTC was established in 1961 by an Ordinance. Its main objectives are to:

1.    Ensure a cheap, speedy, secured, comfortable and modern transportation

       system.

2.    Help develop non-government transport system.

3.    Play an important role in controlling the transport quality and transport

       fare.

4.    Development skilled manpower in transport sector thorough training.

5.    Play a strategic intervention role for a sound and organized transport

       system.

Railway Communication:

Bangladesh Railway is regarded as a cheap and eco-friendly mode of transport. In maritime trade, the Chittagong Sea Port plays a major role. Beside the role or Mongla Sea port and Bangladesh Inland water Transport Authority is also important in transporting passengers and freights. Bangladesh Shipping Corporation is working to provide efficient shipping facilities on international water route. The Department or Shipping performs its regulatory role by enforcing relevant maritime laws and also protects the interest of the crews. Public and private initiative is continuing in the infrastructure development of the land ports established near the border areas or the country. Civil Aviation Authority is responsible for establishment and development of the infrastructure necessary for aircraft operation and at present, it is maintaining 3 international and 5 domestic airports.

E-mail::

Electronic mail, popularly known as ‘e-mail’, is the communication of textual messages via electronic means. Electronic mail communication is user to user via the computer. E-mail is delivered to individual electronic mail boxes based in computers. In order to operate an e-mail system, we need a personal computer, a modem & a telephone connection. The world is getting so smaller & smaller with the blessing of science. Now a man from one part of the world can communicate with a person of another part of the world within a second. E-mail has made this process easier. E-mail, communication in the latest invention in the communication system. It helps all classes of people.

An important advantage of e-mail is its ability to reduce the consumption of paper in the office. Internal memos & reports can be exchanged electronically without using paper. Being a computer based messaging system; files prepared on computers can be instantly copied & easily exchanged as e-mail. This facility has the potential of improving office efficiency considerably.

Fax:

 Fax (short for facsimile, from Latin fac simile, “make similar”, i.e. “make a copy”) is a telecommunications technology used to transfer copies (facsimiles) of documents, especially using affordable devices operating over the telephone network. The word telefax, short for telefacsimile, for “make a copy at a distance”, is also used as a synonym. Although fax is not an acronym, it is often erroneously written as such (“FAX”). The device is also known as a telecopier in certain industries. When sending documents to people at large distances, faxes have a distinct advantage over postal mail in that the delivery is nearly instantaneous, yet its disadvantages in quality have relegated it to a position beneath email as the prevailing form of electronic document transferral. Satellite & Microwave Technology:

Since the introduction of modulated microwaves in the 1920’s for communication between two distant points, this technology has gone through a tremendous amount of development. However, these links were limited to distances within the ‘line of sight’ (roughly 30 kilometers). Thus, the need for orbiting satellites to relay information over long distances was realized; pilot concepts evolved in the early 1950’s and were followed by the successful deployment of communication satellites a decade later. Today satellites of all shapes and capabilities have been launched to serve almost all the countries of the World. Most communication satellites are in geo-stationary orbits (some 35,800 km above the Earth’s surface) and are able to ‘see’ nearly one half of the Earth from this vantage point. To provide continuous coverage to any point on Earth, only three satellites in such an orbit are sufficient [1]. However, signals are weakened about a hundred times after traveling these large link distances, thus necessitating the usage of high gain antennas and powerful transmitters. A more pertinent problem, however, is the delay and echo often experienced in long distance phone calls that use these satellites.

Optical Fiber Technology:

Faced with the aforementioned fundamental shortfalls of a satellite-based system, real interest in optical communication was aroused with the invention of the laser in early 1960’s. Proposals for using optical fibers to avoid degradation of the optical signal while propagating through the atmosphere were made almost simultaneously in 1966 [2]. Early systems exhibited high attenuation (1000 dB/km). Today, less than 40 years on, attenuation of less than 0.2 dB/km is easily achieved for a carrier wavelength of 1.55m as shown in Figure 2. Figure 2: Loss characteristics of a silica optical fiber showing the three wavelengths of interest. Thus the majority of the transmission and receiver systems are geared for operation at this wavelength.

Internet:

Internet is the largest discovery of science & the greatest advancement in the field of communication. It is the computerized process with telephone set. To get internet connection, it requires a modern telephone line & a different sort of software for using the network system. Like telephone number internet is maintained by its own number. There are two types of internet. They are on-line internet & off-line internet. Internet usually gets connection from three networking systems. They are LAN (Local Area Network). MAN (Metropoliton Area Network) & WAN (World Wide Area Network). Now- a- days an internet is of great, use to us. It has made the world smaller & brought the world within our reach. We can get information on every matter within a very short time. It has widened our knowledge & made us thirstier for the unknown. It is a miracle. It works like Aladin’s magic Lamp.

 Internet is a computerized network of information. The activities of the internet are very smooth, easy & rapid. A man can dial a number from his computer & a link to the internet will soon give him a connection in & outside the country according to his expectation.

The first connectivity of internet was only in 1996. Though It was somewhat late, over the past few years the growth is rapid. The government’s high internet tariff is impeding the growth of this sector. Recently the government is decided to reduce the tariff 50%.

Internet Service Providers (ISPs): As of 2005 more than 180 Internet Service Providers are operating in the country. ISP’s are regulated by the Bangladesh telecommunication regulatory commission (BTRC).

Internet users: The number of internet users in Bangladesh is now 450,000(2007) compared to 100,000 in 2000.

(a)Broadband Internet Access:

Though broadband internet access is available it charges high for high speed connection than other south asian countries.Broadband internet and e-commerce in Bangladesh is slowly progressing.WiMAX service is now available from some internet service providers.

(b)Submarine cables:

SEA-ME-WE 4 or South-East Asia – Middle East – Western Europe 4. The landing site is Cox’s Bazar, Bangladesh.

Radio:

Bangladesh Betar  is the state-owned radio broadcasting organization of Bangladesh. It was also known as Radio Bangladesh between 1975 and 1996.

Radio transmission in the region now forming Bangladesh started in Dhaka on December 16, 1939. Initially, the station was located in old Dhaka. Later, the station was relocated to Shahbag. It played an important role during the Bangladesh Liberation War of 1971. On March 26, 1971, the broadcasting center of Radio Pakistan was used to transmit a declaration of independence, which was picked up by a Japanese ship in the Chittagong Harbor and retransmitted. During the war, it was known as Shwadhin Bangla Betar Kendro (Independent Bengal Radio Station). Due to heavy shelling, the station had to be relocated several times, and ultimately moved to Calcutta on May 25, from where it would broadcast until the end of the war. On December 6, it was renamed Bangladesh Betar.

Satellite Channels:

The channels that go air world-wide & are telecast with the help of satellite are satellite channels. Dish antenna is large sized & dish shaped. It is much improved & more powerful version of the earlier antennas. Dish antenna has brought about a revolutionary change in the world of showbiz. It can provide thousand connections simultaneously. Through dish antenna now one can watch any program of any channel on T.V.  Earlier, the views could watch only domestic T.V.  programs. Sometimes, it was boring & dull. But the viewers had no way out of this.

Now dish antenna has offered the viewers thousand options. One can watch sports, movies, news & many other entertainment programs whenever he likes. Dish antenna has world closer than it was before.

There are many advantages of satellite channels. We can learn many types, of educational things. We can also know about co curriculum works. It also increases our creativity & brave. We can watch adventurous things by the satellite.

We can use new types of channels through satellite channels. Our creativity will be improved by satellite channels. Then our brave will be increased by satellite channels.

List Of Television Stations:

The first television signal broadcast in Bangladesh was in 1964 by the state-owned television network BTV. From then onwards BTV had a virtual monopoly until the late 1990’s. Ever since then a number of stations had arrived. Many have also shut down in the process.

Telecom System in Bangladesh:

Jump to: navigation, search

The Bangladesh telecommunications system contains several subsystems. A general assessment of the telephone system is that it is totally inadequate for a modern country. The domestic system is undergoing modernization. Digital systems; trunk systems including VHF and UHF microwave radio relay links, and some fiber-optic cable are being introduced in the cities. The international system consists of two Intelsat satellites in geostationary orbit, international radiotelephone communications and landline services to neighboring countries.

Code System: The telecom sector in Bangladesh is rapidly emerging.

  The area code has 1-4 digits.

  The Subscriber Number has 3-7 digits.

  The Trunk Prefix is “0”.

We can express our all the opinion through telecommunication. That’s why most of the telecommunication company has reduced their mobile service cost. We can call to others, chat with others, send massages, browse, use internet, picture messages etc. It is very cheap.

Telex:

Telex communication is also electronic in nature.  Telex communication is terminal to terminal. In telex, messages designed to a number of users are sent to the same terminal from where it is distributed in a printed from by an operator.

1) 2-ply and 3-ply
2) Size: different sizes available
3) Carbonless paper roll
4) Instant and clear copy image, which presents excellent optical density and light
resistance;
5) Good dimensional stability and curl control for converting;
6) High surface strength, can not smear or rub off onto hands or clothes.

Many companies have been providing Telex services to its international customers. As the use of telex services declines around the world this companies remain committed to its long term provision. Save costs with no need for server software, desk top licenses, modems, hardware, telex lines or expensive maintenance contracts. This company also provides internet Telex solutions. They are given below:

Wireless Communication:

Wireless Connectivity:
Wireless – Term describing communication that requires no wire between two communicating points.
Connectivity – The ability to connect communications systems to exchange data or share resources.
Wireless Connectivity – Wireless connectivity involves all the new wireless devices and technology. It brings in all the new ways of collaboration, mobile, so that now we can manipulate, share and shape our digital content from anywhere, with anyone totally mobility.

Wireless can be divided into some groups such as:

*  Fixed wireless — the operation of wireless devices or systems in homes and offices, and in particular, equipment connected to the Internet via specialized modems

*  Mobile wireless — the use of wireless devices or systems aboard motorized, moving vehicles; examples include the automotive cell phone and PCS (personal communications services)

*  Portable wireless — the operation of autonomous, battery-powered wireless devices or systems outside the office, home, or vehicle; examples include handheld cell phones and PCS units

*  IR wireless — the use of devices that convey data via IR (infrared) radiation; employed in certain limited-range communications and control systems

Cell Phones:

A mobile or cellular telephone is a long-range, portable electronic device for personal telecommunications over long distances. The phones have a low-power transceiver that transmits voice and data to the nearest cell sites, usually 5 to 8 miles (approximately 8 to 13 kilometres) away. When the cellular phone or data device is turned on, it registers with the mobile telephone exchange, or switch, with its unique identifiers, and will then be alerted by the mobile switch when there is an incoming telephone call. The handset constantly listens for the strongest signal being received from the surrounding base stations. As the user moves around the network, the mobile device will “handoff” to various cell sites during calls, or while waiting (idle) between calls it will reselect cell sites.
Cell sites have relatively low-power (often only one or two watts) radio transmitters which broadcast their presence and relay communications between the mobile handsets and the switch.

VOIP:

Voice over Internet Protocol, also called VOIP, IP Telephony, Internet telephony, Broadband Telephony, Broadband phone & voice over broadband is the routing of voice conversations over the Internet or through any other IP-Based Network.

Skype users essentially make telephone calls and video calls through their computer using Skype software and the internet. The basis of the system is free communication between users of Skype software; however the product also allows Skype users to communicate with users of regular landline and mobile telephones. This software is currently available free of charge and can be downloaded from the company website, but the software is proprietary and the Skype protocol is unpublished.

Conclusion:

The role of communication in the economic development of Bangladesh, which is to be communicated, how and why-are key question in communication. In disseminating the message, selection of appropriate media is as important as language. Wrong selection of media and inadequate and improper communication supports lead to failure in development.

Telex:

Telex communication is also electronic in nature.  Telex communication is terminal to terminal. In telex, messages designed to a number of users are sent to the same terminal from where it is distributed in a printed from by an operator.

Wireless Communication:

Wireless Connectivity:
Wireless – Term describing communication that requires no wire between two communicating points.
Connectivity – The ability to connect communications systems to exchange data or share resources.
Wireless Connectivity – Wireless connectivity involves all the new wireless devices and technology. It brings in all the new ways of collaboration, mobile, so that now we can manipulate, share and shape our digital content from anywhere, with anyone totally mobility.

Wireless can be divided into some groups such as:

*  Fixed wireless — the operation of wireless devices or systems in homes and offices, and in particular, equipment connected to the Internet via specialized modems

*  Mobile wireless — the use of wireless devices or systems aboard motorized, moving vehicles; examples include the automotive cell phone and PCS (personal communications services)

*  Portable wireless — the operation of autonomous, battery-powered wireless devices or systems outside the office, home, or vehicle; examples include handheld cell phones and PCS units

*  IR wireless — the use of devices that convey data via IR (infrared) radiation; employed in certain limited-range communications and control systems

Cell Phones:

A mobile or cellular telephone is a long-range, portable electronic device for personal telecommunications over long distances. The phones have a low-power transceiver that transmits voice and data to the nearest cell sites, usually 5 to 8 miles (approximately 8 to 13 kilometres) away. When the cellular phone or data device is turned on, it registers with the mobile telephone exchange, or switch, with its unique identifiers, and will then be alerted by the mobile switch when there is an incoming telephone call. The handset constantly listens for the strongest signal being received from the surrounding base stations. As the user moves around the network, the mobile device will “handoff” to various cell sites during calls, or while waiting (idle) between calls it will reselect cell sites.
Cell sites have relatively low-power (often only one or two watts) radio transmitters which broadcast their presence and relay communications between the mobile handsets and the switch.

 VOIP:

Voice over Internet Protocol, also called VOIP, IP Telephony, Internet telephony, Broadband Telephony, Broadband phone & voice over broadband is the routing of voice conversations over the Internet or through any other IP-Based Network.

Skype users essentially make telephone calls and video calls through their computer using Skype software and the internet. The basis of the system is free communication between users of Skype software; however the product also allows Skype users to communicate with users of regular landline and mobile telephones. This software is currently available free of charge and can be downloaded from the company website, but the software is proprietary and the Skype protocol is unpublished.

Conclusion:

The role of communication in the economic development of Bangladesh, which is to be communicated, how and why-are key question in communication. In disseminating the message, selection of appropriate media is as important as language. Wrong selection of media and inadequate and improper communication supports lead to failure in development.
