According to the BBC English Dictionary, Radio is defined as ‘the
broadcasting of programmes for the public to listen to, by sending out signals
from a transmitter.’ Also, the Wikipedia online Encyclopaedia defines it as
‘the radiation or wireless transmission of electromagnetic signals through the
atmosphere or free space.’ In the same vein, a piece of equipment used to
listen to radio programmes or receive radio signals is also referred to as a
Radio.
Information such as sound is carried by systematically changing or
modulating some property of the radiated waves including amplitude, frequency,
phase, or pulse width. When radio waves strike an electrical conductor, the
oscillating fields induce an alternating current in the conductor. The
information in the waves can be extracted and transformed back into its
original form.
A radio communication system
sends signals through the radio. The radio equipment involved in communication
systems include a transmitter and a receiver, each having an antenna and
appropriate terminal equipment such as a microphone at the transmitter and a
loudspeaker at the receiver in the case of a voice-communication system.
The etymology of radio or radiotelegraphy reveals that it was initially
called ‘wireless telegraphy’, which was later shortened to ‘wireless’ in
Britain. The prefix ‘radio-‘ in the sense of wireless transmission, was first
recorded in the phrase ‘radio conductor’ – a description provided by the French
physicist, Edouard Branly in 1897.
In recent years, the more general term ‘wireless’ has gained renewed
popularity through the rapid growth of short-range computer networking like
Wireless Local Area Network (WLAN), Wi-Fi, Bluetooth, as well as mobile
telephony such as GSM and UMTS. Today, the term ‘radio’ specifies the actual
type of transceiver device or chip, whereas ‘wireless’ refers to the lack of
physical connections; suffice to say that, the former talks about radio
transceivers only while the latter talks about wireless devices and wireless
sensor networks generally.
Presently, the radio set seems to be the easiest and most affordable
means of telecommunication. Until the invention of the social media, it was
widely regarded as the only handy medium for information dissemination. It is
the easiest, in the sense that most current electronic devices such as GSM
among others have access to radio signals; most affordable, in the sense that
anyone regardless of his/her status can boast of an access to radio
communication.
For instance, a portable radio set can be obtained at the rate of three
hundred naira (#300) in any local market in Nigeria, and the Direct Current
(DC) battery, which could be used to power the said device, can be purchased at
most sixty naira (#60). But a GSM, which could guarantee an access to a certain
social media such as Facebook, can never be obtained at less than five thousand
naira (#5000); in most cases, it takes only Symbian phones such as Android, Phantom,
iPod, and Blackberry for one to gain access to most recent social media like
BBM, Whatsapp, Badoo, Twitter, Instagram, and what have you, and such phones
cannot be obtained at less than twenty thousand naira or thereabouts.
The television communication system is not left out in this analysis or
comparison. In an average electronics market in Nigeria, a 14-inches television
set is sold at about sixteen thousand naira or above. And after purchasing the
TV Set, the consumer still needs to obtain an outdoor antenna to enable him
boast of absolute clarity while using the device. Even, sometimes he may still
need to buy a Power Generating Set to aid power supply since there is no
assurance for steady power supply in Nigeria.
Therefore, another remarkable phenomenon to be considered while comparing a radio communication system with other means of telecommunication is that due to instability of power supply in most developing nations like Nigeria, acquiring information through the communication system in question has remained the only reliable means of telecommunication in existence.
On the other hand; considering other means of communications such as the
print media, how many Nigerians can afford a one hundred and fifty naira (#150)
or one hundred naira (#100) newspaper as the case may be, on a daily basis, or
even a four hundred naira (#400) newsmagazine weekly? Needless to say; the
print media is not just expensive to an average Nigerian but no doubt an
exorbitant means of communication, compare to radio broadcasting service.
Today Friday February 13, the world over is commemorating the 2015 World Radio Day. The Day was proclaimed on 3rd November 2011 during the 36th General Conference of the United Nations Educational, Scientific and Cultural Organization (UNESCO). It was originally proposed by the Spanish Kingdom; the first procedure was in January 2008 by the President of the Spanish Radio Academy, Mr Jorge Alvarez. The Day 13th February was chosen in line with or in recognition of the day the United Nations Radio was established in the year 1946.
Afterwards, in December 2012
precisely, the General Assembly of the United Nations endorsed the Proclamation
of World Radio Day thereby enabling it to become a Day to be celebrated by all
the UN Member States, agencies, as well as their partners. Various radio
industry bodies around the world have been supporting the initiative by
encouraging radio stations in developed countries to assist those in the
developing world.
As the global society celebrates the annual World Radio Day, there is
need for the totality of the Nigerian Radio Broadcasting industry to be
overhauled. In this regard, the concerned bodies should as a matter of urgency,
be mandated to switch over from the ongoing analogue broadcasting to digital
broadcasting.
Thus, in view of the above remark, the recent mandate of the Nigerian
Communication Commission (NCC) in collaboration with the National Broadcasting
Commission (NBC) in line with the directive of the International
Telecommunication Union (ITU) regarding migration from analogue to digital
broadcasting by all the broadcasting firms in the country not later than June
17, 2015, ought to be very taken seriously by the concerned authorities.
On their part, the members of the National Assembly are expected to
enact a formidable law that would mandate the closure of any media firm that
fails to meet the stipulated deadline as well as sanction anyone that attempts
to return to analogue broadcasting in future. The proposed law should also
mandate NBC and other relevant authorities to ensure that provision of digital
broadcasting equipment by any upcoming or intending media firm is a
prerequisite to issuance of license to the company in question.
In addition, the Broadcasting Organization of Nigeria (BON) ought to in
its capacity assist the government in conscientizing their members on the
significance of digital broadcasting. Therefore they should at all times
maintain a cordial relationship with the NBC with the aim of actualizing a
totally digitalized broadcasting industry in Nigeria. The generality of the
civil society is as well expected to follow suit in this sensitization crusade.
Yes, radio broadcasting service remains the most reliable and affordable means of communication in the world, but it is worthy to note that its reliability or affordability is liable to become a thing of the past if abused or if adequate attention is not given to the sector. Think about it!
