Abstract –In this modern era, due to the rapid growth of
technology, the usage of mobile has become wide which leads
to implementation of enormous communication towers. The
source input for the cellular towers depending on the power
requirement in the developing countries are always greater
than the generated. Hereby our idea is to reduce the energy
usage and emission of CO2 into the environment by Green
Radio Technology, which prefers environment friendly
approach towards the mobile communication. The
methodology in Green Radio Technology is dynamic switch
over of towers. The dynamic switch over is based on the
frequency handling of a tower. Based on this, a tower may
remain either in an active state or idle state.

1. INTRODUCTION
Cellular phones first become widely available in 1990’s and
the corresponding usage of cellular phones also increased in
parallel. This parallel increase in usage of cellular phones
has lead to implementation of communication towers called
base stations.. The base stations comprises of electronic
equipment and antennas that receive and transmit radio
frequency signals. Effective energy management is the
essential requirement for successful operation of mobile
communication networks. Energy saving is one of the
important parameter for mobile operators because directly
and indirectly mobile operators are creating huge loss to the
society by wasting power. As a part of energy management,
reduction of energy consumption by the towers is achieved
by Green Radio Technology.
Fig-1.Cellular Network Power consumption
Fig-2.CO2 emission from base station (observed at various
distance in atmosphere)
The FIG1 clearly demonstrates that, the base stations alone
consume more power than other parameters in cellular
networks. The FIG2 shows the CO2 emissions in atmosphere by
subscribers from base stations. The impact due to several
million towers installed in a country is unimaginable.
Moreover, in communication towers, power is not only
used for the signal transmission process but also running
the cooling unit of generator and light indicator along with
lighting arrestor. These cooling unit operates throughout
the day irrespective of the temperature and environmental
change. So by turning off the cooling unit at unnecessary
condition will reduce considerable amount of power usage.
Green Radio Technology prefers the use of renewable
energy sources like solar and wind in the place of
conventional source (diesel). In general, all the towers
remains on working state irrespective of the traffic (number
of users) which leads to the wastage of power. In order to
overcome this, our project proposes a comprehensive
approach towards an energy efficient operation of
communication towers during less traffic (less number of
users) by keeping only one mobile tower on working state to
take up all communications while the remaining towers stay
in idle mode. Hereby our objective is to reduce the energy

consumption in the base stations and reduce the amount of
CO2 emission.

stations is important.

3. EXISTING SYSTEM
The architectural operation of presence scenario is not
energy efficient. On an average, a typical diesel generator
that is used for supplying power for communication towers
consumes seven million of diesel per day. This results in
emission of 85 kilogram of carbon per day into the
atmosphere. On the other hand, irrespective of the user
frequency (number of users) all the towers in an area are
turned on. This leads to the considerable wastage in power.
4. PROPOSED SYSTEM
In order to overcome the disadvantages we have proposed a
technique Green Radio Technology. This technique limits
the usage of power and reduce the CO2 emission. Solar
photo voltaic based power generation is believed to be a
solution for reduction of carbon dioxide emission. The other
disadvantage is overcome by activating the tower based on
the user strength that is in accordance with the user
strength in a region, the towers in the particular region is
turned on/off.
5. BLOCK DIAGRAM
In this block diagram, the current and voltage sensing circuit
helps to sense the power and give the corresponding output
to monitoring system. The responder frequency which will
be received from the main server will help microcontroller
to decide whether tower should activate or not ,this is
achieved by setting predefined threshold frequency and that
corresponding received value can be displayed in PC. Local
temperature and humidity monitoring sensor senses the
temperature and humidity level of the environment and
controls A/C and cooling fan according to the temperature.
If the current and voltage sensing output is zero, it indicates
that the number of users is zero in that instant of time
.Similarly if number of users using the cell phone tower get
increased then relay will activate neighbouring towers
6. SOFTWARE IMPLEMENTATION
The tool which we are going to use is Visual Basic. Visual
Basic is Windows based application which is easy to learn. It
is one of the language to support programming which
especially suited to graphical user interface(GPI).Visual
Basic is ease to use which makes us to work in dialog boxes
etc and they required only less lines of programming to
control.

7. METHODOLOGY
A. GREEN RADIO TECHNOLOGY
Power consumption in communication towers is reduced by
adapting the network capacity to the actual demand at a
given time. The cellular tower working will be based on the
peak and off peak hours. In current scenario, even at the
time of less traffic(less number of users) condition in a
particular region ,all the towers were made to work. This
results in wastage of power. Our idea is to propose a new
methodology to reduce this power wastage. The
methodology is dynamic switch over of towers. It is as
follows. Based on the survey conducted, the time zone of
less traffic condition is extracted .During that interval, only
one tower (primary tower) is made to be active and the
remaining towers were set to remain in idle state. When the
frequency handling of primary tower is exhausted, the other
tower (secondary tower) is activated. Consequently, if the
number of users count decreases again, the secondary tower
is made idle and the primary tower alone is capable of
handling the users.
B. RENEWABLE ENERGY SOURCE
On an average, each tower consumes 28 litres of diesel per
day which results in emission of 85 kg of carbon in
atmosphere .The total CO2 emission rate by millions of
towers in country is unimaginable. In order to reduce CO2
emission, the power used by the base station is reduced.
This is achieved by controlling different parameters within
the base station. Communication towers, in addition to
signal transmission and reception , consumes power for
cooling unit that consists of air-conditioner ,cooling fan
,lightning arrester along with a light indicator. By controlling
these parameters based on their need, the reduction of
considerable amount of power consumption is achieved
.Also by using renewable resources like solar power, wind
energy in place of conventional diesel source, the emission
of green house gases is reduced.
8. CONCLUSION
In this paper, a framework for efficient power utilization in
cellular towers is proposed. Thus by introducing Green
Radio Technology, energy usage by base stations will be
limited as much as possible and hence the emission of
harmful green house gases (carbon dioxide) will be reduced.
This leads to an environmental friendly approach towards
wireless communication.
