Proceedings
Members of the committee deliberated on the issue on 18.4.2012 and
24.4.2012. Civil Society Members from Mumbai shared their view points with the
committee members on 1.5.2012 on related issues i.e. restriction on setting up
of BTS towers and reduction in RF radiated power from BTS antennas to 1/10th of
the existing level i.e. from 20 watt per carrier to 2 watt per carrier. The Service
Providers, Cellular Operators Association of India (COAI), TAIPA and
representative of ASSOCHAM expressed their view points with the committee
members on the issue on 2nd May 2012.
The representatives of Telecom Equipment Manufacturers and Antenna
Manufacturers expressed their view points on tower installation, related issues
and in-building solutions, for Radio frequency coverage in telecom networks with
the committee members on 3.5.2012. Representatives from M/s. Alcatel, a
telecom equipment manufacturer gave presentation to the committee members
on low power Micro Cell, Pico Cell, Femto Cells and in-building solutions for
telecom networks on 4.5.2012.
Chairman of the committee discussed the issues with BSNL/MTNL officers
in Mumbai and Ahmedabad on 21st & 22nd May 2012. It was expressed that use
of mobile handsets is the real concern and not the BTS as the handset is very
closed to the human body and suggested that govt. should educate the public on
its own expenses about the safe use of handsets.

General
_______________________________________________________________________________________________ Report of Departmental Committee

The infrastructure used in the cellular communication network has both
Active and Passive components. The passive infrastructure is the land, buildings,
shelters, antenna systems, towers/masts, power supply and battery back-up etc.
The active infrastructures are base station trans-receiving radios, popular names
being BS (Base station), Node-B (in 3G networks) and e-Node B (in LTE standards
), Microwave radios for back-bone, backhaul, other RF / base band equipment and
various switching and network control equipments etc.
2.0 The mobile communication networks use radio frequency propagation for
transmission of signals. These radio frequencies are electromagnetic waves. The
frequency bands of these waves fall under the category of non-ionizing radiation,
which does not disturb the cell structure of the human body. However, in order to
keep the human exposure to these radiations within limits, the International
standards organizations have developed certain limits. These limits have also been
adopted in India. The limits take care of the radiations taking place in all the bands
used by telecom service providers. These limits take into account adequate factor
of safety for all population.
3.0 An Inter Ministerial Committee consisting of officers from DoT, ICMR,
Ministry Environment & Forests and Dept. of Bio-technology was constituted to look
into the effects of EMF radiation from mobile base stations and mobile handsets on
health. The acceptance of the recommendations of the Committee was
communicated vide DoT OM 32-7/2010-EW dated 17th Nov. 2011 and necessary
directives for revised exposure limit of base station emission level to 1/10th of the
existing level and SAR of mobile hand-set of 1.6 watt per kg effective from
1.9.2012 was issued by the AS and IP Units of DoT respectively.
4.0 The inter-ministerial committee in its report had recommended formulation
of uniform guidelines at national level, enforcing restrictions for setting up of BTS
towers, creation of appropriate frame work for structural safety clearance of towers
set up on roof-top, identification of location for installation of mobile towers in
master plan of town and cities in consultation with Ministry of Urban Development
and induction of new technology low power transmitters with in-building solutions
for future expansion of telecom network in the country.
_______________________________________________________________________________________________ Report of Departmental Committee

5.0 As per the existing policy Wireless Planning & Coordination Wing of DoT
issues siting clearance for installation of mobile towers for each and every site from
the point of view of interference with other wireless operators, aviation hazard and
obstruction to any other existing microwave links. The siting clearance is issued
without prejudice to applicable bye-laws, rules and regulations of local bodies such
as Municipal Corporations/Gram Panchayat etc. Before installation of mobile towers
the telecom service providers are required to obtain necessary permission from
local bodies.
6.0 The base stations, the transmission towers and their antennas provide the
link to and from mobile phones and fall in the category of life-line buildings. The
towers/antennas are located in sites based on the radio propagation characteristics
in the network and are spread over in all areas, lease rented buildings. The
buildings over which the towers are erected are generally not analyzed for the
associated risk of earthquake and appropriate retrofit measures from structural
safety point of view is required to be taken. Such an analysis is necessary to ensure
compliance with the relevant BIS provisions.
7.0 In Orissa Super Cyclone and Bhuj Earthquake there was large scale damage
to property and essential services including telecommunication. The latter added to
the problem of overall disaster management including search and rescue. BIS
subsequently revised the code for earthquake resistance design of structures (IS
1893) identifying revised seismic zone with additional earthquake resistance
features. Cellular mobile BTS infrastructure falls under the category of life line
installation and as such compliance to relevant revised BIS provisions in the
respective areas is necessary so as to effectively respond to any severe disaster
situations. The life-line installation category should facilitate priority in land
allocation, power connections, and maintenance of service etc.
8.0 At present there is no uniform policy guidelines for location of towers. This
has resulted in unregulated telecom BTS cellular infrastructure in country. IMC
desired that there is a need to Identify/ earmark some areas in the master plan in
the new cities for cellular towers. This will, however, not be the ultimate solution as
_______________________________________________________________________________________________ Report of Departmental Committee
9
the siting of tower shall be as per the WPC clearance and radio frequency coverage
requirements.
9.0 At present the RF power radiated from BTS antenna is 20 watt per carrier.
In a shared BTS site, with multiple operators, the radiated power from a single
tower goes as high as 100 -150 watt per sector. In certain cases, the high-powered
towers can be avoided with the introduction of “Energy efficiency analysis process”
for installing large vs. small cells i.e. low power Micro Cell, Pico Cell, Femto Cells
and other in-building solutions in telecom networks.

Guidelines for setting up
of
BTS towers
_______________________________________________________________________________________________ Report of Departmental Committee
11
Telecom infrastructure falls in the category of lifeline installations and BTS
tower is a critical infrastructure for providing essential communication service.
2.0 As per the Present Procedure, the Siting clearances for installation of BTS
towers are issued by SACFA (Standing Advisory Committee on Frequency
Allocation), WPC, DOT. SACFA clearances are issued after getting 'no objection'
from various SACFA members (such as Airport Authority of India, JCES etc.) who
carry out detailed technical evaluation including field surveys. The technical
evaluation by SACFA members is done primarily for –
i) Aviation hazards.
ii) Obstruction to line of site of existing/planned networks
iii) Interference (Electro Magnetic Interference (EMI)/Electro Magnetic
Compatibility (EMC)) to existing and proposed networks.
The site location for tower installation is decided by the concerned
service provider as per the technical and commercial requirements.
3.0 Siting clearances are issued without prejudice to other applicable byelaws,
rules and regulations of Local bodies such as Municipal Corporation, Gram
Panchayats etc”. Therefore, before installation of towers, Service Providers obtain
necessary clearances from concerned local authorities/State Govt. bodies. This pre-
condition is clearly laid down in SACFA siting clearances.
4.0 As stated above, before installation of towers the services providers are
required to obtain necessary clearances from the local authorities also. At present
there is no restriction for location of the mobile BTS towers. In the absence of
national guidelines, some state governments have issued their own guidelines. The
Committee has noted that the local bye-laws issued by Delhi and West Bengal
enforce certain precautionary measures while giving permission for installation of
towers like
“avoid installation of base station antennas within the premises of schools
and hospitals as children and patient are more susceptible to EMF radiation.
Installation of base antennas in narrow lanes to reduce the risk caused by any
_______________________________________________________________________________________________ Report of Departmental Committee
12
earthquake or wind related disaster. Base station antenna should be at least 3 mt.
away from nearby building. Signboards and warning signs in base station antenna
sites for identification. Towers in residential areas only in consultation with the
concerned residents’ welfare association and so on.”
There are some other states like Tamilnadu and Karnataka where no
permission is required for erection of a tower. The infrastructure providers intimate
the state government and install the tower.
5.0 The local bye-laws in regard to setting up of cellular mobile base stations
vary from state to state and there is no uniformity in the guidelines for grant of
permission for installation of towers. In various states, the service providers face
difficulties in obtaining the clearances. Further, for installation of mobile towers
the telecom service providers are required to pay one-time fee to the local
municipal authorities. Some states are charging the “renewal fees” also. The fee
structure specified by the State/Local Authorities varies with the location of the
installation and also from state to state.
6.0 The committee is of the view that formulation of uniform guidelines in the
matter for adoption of structural safety measures, fee structure, taxes, other
charges and ROW etc. of cell site / base station at national level is very much
necessary so that there will be uniformity in approach for grant of permission for
installation of towers by the local bodies / state authorities. The idea is that the
state government/ local bodies charge a simple administrative fees for such
clearances.
7.0 The Committee observed that the antenna for Macro cells in a mobile
phone network have power outputs of 20 watts per carrier and are mounted on
ground based masts, roof-top and other existing structures at a height 30-60 mt.
that provides a clear view over the surrounding buildings to have a larger area
coverage. Further, CMTS/UAS licenses provide mobile services that are
governed under Indian Telegraph Act 1985. The cellular towers are being
installed to provide radio coverage in extending mobile phone services and the
_______________________________________________________________________________________________ Report of Departmental Committee
13
Telecom Service Providers pay annual license fee to the Dept. of Telecom (Govt).
As such the recurring fee levied by the state/local authorities is not appropriate.
8.0 The committee recommends to-consider imposing restrictions on
installation of BTS towers within the compound of schools and hospitals as the
children and the patients may be more susceptible to the possible effects of
electro-magnetic radiations. In-door building solution for low wattages may be
deployed.
9.0 The committee also recommends the implementation of uniform
guidelines for installation of towers / antenna.
10.0 The committee is of the view that in order to have uniformity in approach
for installation of mobile BTS towers, DoT may issue a model draft guidelines for
setting up BTS towers so that local authorities verify them and issue expeditious
clearance for installation. Following uniform measures are recommended for
inclusion in the draft guidelines for State/local municipality bye laws.
i) Considering the importance of telecom services, the service
provider/infrastructure provider should have unrestricted right of way
for installation of mobile tower, irrespective of land usage.
ii) Installation of base station antennas in narrow lanes may be avoided in
order to reduce the risk caused by earthquake or wind related disaster.
iii) Installation of base station antennas within the premises of schools
and hospitals may be avoided because children and patients may likely
to be more susceptible to electro-magnetic fields. In-door building
solution of low wattages may be deployed.
iv) Base station antennas to be away from nearby buildings and above the
ground and roof to ensure compliance to the prevailing radiation limits.
v) Access to base station antenna site to be prohibited for general public
by suitable means such as wire fencing, locking of the door to the roof,
etc.
vi) The access to tower site for the maintenance personnel also to be for a
minimum period as far as possible.
_______________________________________________________________________________________________ Report of Departmental Committee
14
vii) Sign boards and warning signs (Danger RF Radiation, Restricted Area,
Don’t enter) are to be provided at base station antenna sites which are
clearly visible and identifiable.
viii) Consent from the owner is required.
ix) Copy of the siting clearance granted by Dept. of Telecommunication to
service providers
x) Structural Stability Certificate from certified Structural Engineer or
from recognized institute like IITs, NITs, CBRI Roorky and CBM,
Faridabad or any of the recognized govt. institution. The Service
providers to file a fresh structural stability certificate after every 5
years.
xi) No permission for installation of cell site / base station to be granted
on buildings which are structurally unsafe.
xii) The provision of DG sets used for mobile towers shall be as per the
provisions under Environment (Protection) Act 1986 and the Noise
pollution (Regulation & Control) Rule 2000 as amended from time to
time.
xiii) Design parameters / necessary drawings for installation.
xiv) NOC from the concerned authority in case of CRZ area, heritage
building, municipality lease-hold property and cess property
xv) The processing fee for grant of approval/renewal/sharing of mobile
BTS towers if any levied by the state / local authorities should be
restricted to administrative expenses if any as the service providers
provide radio coverage in extending mobile phone services and other
facilities that are governed under Indian Telegraph Act 1985 and pay
annual licence fee to Dept. of Telecom.
xvi) The permission of local authorities should be automatic, in case the
other requirements mentioned above are met. However, if the local
authority decides to have a prior approval system, then it needs to
process the application within a period of 30 days from the date of
submission, in a single window mechanism. The said application will
be deemed to have been approved after the expiry of aforesaid 30
days, to facilitate faster roll out.

Structural Safety for Towers
on
roof top
_______________________________________________________________________________________________ Report of Departmental Committee
16
The base stations, the transmission towers and their antennas provide
the link to and from mobile phones and fall in the category of life-line buildings.
Among others, the mobile towers are erected in areas spread all over towns and
cities, in rented/leased lands/roof tops. The buildings over which the towers are
erected are generally not analyzed for the associated risk of earthquake; and
appropriate retrofit measures from structural safety point of view are also not
taken which are necessary to ensure compliance with the relevant BIS
provisions.
2.0 In the cases of natural disasters such as earthquakes etc. in the past,
there were large scale damages to the property as well as essential services
including telecommunications. Therefore, it is to be ensured that
telecommunication services are not disrupted during such events. With this
objective in view, the design, installation, maintenance and upkeep of cellular
towers are very crucial.
3.0 BIS Code for Earthquake Resistance Design of Structures (IS 1893) was
revised identifying revised seismic zones with additional earthquake resistant
features and accordingly the design, fabrication, material and erection of mobile
towers are to be made so as to conform to latest BIS code applicable to the
respective areas/zones.
4.0 In view of above, the Structural stability certificate should be from one of
the following institutes:-
Indian Institutes of Technology (IITs).
Central Building Research Institute (CBRI), Roorkee/its units.
Rail India Technical and Economic Services Ltd. (RITES).
National Council for Building Material, Faridabad/its units.
Indian Institute of Technology (IIT), Roorkee.
Respective State PWDs/CPWD
Any qualified registered structural engineer
_______________________________________________________________________________________________ Report of Departmental Committee
17
5.0 Advisory guidelines / norms pertaining to structural safety of ground-
based towers and of the Building/towers established on roof-top of buildings
need to be formulated considering the following:-
a) The revised code now covers additional earthquake/cyclone resistant
features. The design, fabrication, material and erection of mobile
towers and the buildings should conform to relevant BIS provisions
in the relevant areas.
b) To undertake exercise of inspection of existing buildings / towers in
Seismic Zones III, IV & V by structural engineers in order to ensure
that these are compliant to revised BIS codes in the relevant areas
and to take appropriate retrofitting measures wherever necessary.
c) To ensure that the new construction in seismically vulnerable zones
follow the norms laid down for safe construction in these areas as
per relevant BIS standards.
d) To use technology and network architecture that would minimize the
number and size/weight of the BTS towers.
e) To submit self certification for structural compliance in respect of
existing/new towers to respective TERM Cell of DoT within specified
time-limit in the prescribed proforma (annexed).
f) Service providers / infrastructure providers to obtain requisite
permission from the concerned local authority before installation of
tower and submit a copy of the permission cell to respective TERM
cell before made operational.
g) All new towers and buildings shall comply with SAFETY PROVISIONS
listed under Annexure A.
_______________________________________________________________________________________________ Report of Departmental Committee
18
h) The certificate furnished by the infrastructure provider shall also be
acceptable. However, responsibility of compliance shall be with
service provider.
i) The TERM Cells of at their discretion may test up to 1-2% of towers
and buildings randomly from IITs, NITs, CBRI Roorky and CBM,
Faridabad or any of the recognized govt. institution. The sites
against which there are public complaints shall also be tested by
TERM Cell of DoT. The cost of the testing shall be borne by the
service provider.
j) If a tower/building fails to meet the criteria of relevant BIS provision
specified, suitable penalty provision as per Telegraph Act may have
to be specified.
k) The details of towers and buildings be hosted on DoT website with
status i.e. self-certified, TERM Cell certified/ not certified etc.
Draft instructions to service providers on disaster resistance buildings
and towers for communication services has been prepared and placed at Annexure- A.

Location of Mobile Towers
in
Master Plan
_______________________________________________________________________________________________ Report of Departmental Committee
20
At present there is no regulation on the location of the towers. One of
the recommendations of the IMC was to identify the location for installation of
mobile towers in the Master Plan of Towns and Cities in consultation with the
Ministry of Urban Development.
2.0 The idea of identification of suitable areas may be aimed at identifying, in
advance, and thus providing for suitable space/area meant exclusively for the
establishment of mobile services antenna farms; which in turn may help address
various issues such as radiation health hazards, noise/air pollution, structural
safety/natural disaster aspects and aesthetics/landscape etc. of the city/town.
3.0 However, the towers are placed at locations which are best suited to
service providers, technical and business requirements/network design e.g.
distribution of towers for a network operating in 700 MHz band would differ from
that from operating in other bands such as 1800 MHz, 450 MHs and 800/900
MHz etc. Installation of mobile towers depends on factors like coverage,
population density, traffic etc. Micro management for identification of location in
the master plan may not be feasible.
4.0 However, it may be considered to examine the feasibility of such a plan
as it would require good amount of spare land area at multiple places in a regular
pattern which will be dedicated to the provision of mobile services antennae only
and to earmark some areas in the master plan for cellular tower parks in
consultation with Ministry of Urban Development.

In-Building Solution
of
Telecom Network
_______________________________________________________________________________________________ Report of Departmental Committee
22
The mobile wireless technology relies upon an extensive network of fixed
antennae. Each individual service provider install single high power tower
antenna and radiate RF power to cater large coverage area, both outdoor and
indoor premises.
2.0 The committee is of the view that high power BTSs may be suitable for
scattered and thinly populated rural/semi-urban areas but the high density urban
areas can be well-served with multiple low power BTSs leading to better
spectrum utilization i.e. same amount of spectrum can be utilized to provide
connectivity to large number of people as well as associated RF health hazard
issues (if any) are also addressed. However, the urban areas may be provided
with better and ubiquitous mobile coverage if the traditional BTSs are augmented
with various in building/micro/pico-cellular solutions.
The high-powered towers can be avoided with the introduction of “energy
efficiency analysis process” for installing large vs. small cells i.e. low power Micro
Cell, Pico Cell, Femto Cells and other in-building BTS solutions in telecom
networks.
3.0 By augmenting the mobile coverage through In-Building-Solutions,
standard cell-sizes can be maintained and issues relating to interference and re-
use patterns etc. can be kept simplified. This will help improve spectrum
utilization efficiency and increase battery life of the hand-sets.
4.0 In uncovered, isolated, scattered and small locations, the outdoor DAS
(Distributed Antenna Systems) concept can also be implemented independently.
5.0 At present, each individual operator install their own proprietary antenna
system within a building leading to large number of antenna for extending mobile
services. With a neutral host antenna system, all TSPs can utilize the same
powerful antenna system, eliminating the need for multiple unsightly antennas
distributed across a building. DAS (Distributed Antenna Systems) protects the
ambience and aesthetics of the property because multiple antennae/wiring
projects are not required. Changing service providers does not lead to the
_______________________________________________________________________________________________ Report of Departmental Committee
23
defacement of property because no change to the wiring is necessary. Service
providers can simply “plug-in” and services are available immediately.
6.0 In all multiplex complexes, both residential and commercial, there should
be provisions of telecom chamber at the ground floor having optical fiber /
copper cable / RF cable connectivity, to each and every flat and allow all the
service providers to extend telecom related facility i.e. broad band, mobile, land
lines and other services.
7.0 In cellular wireless network, such as GSM, the Pico cell base station is
typically a low cost, small, reasonably simple unit that connects to a base
station. The Pico cell and Femto cell base stations typically cover a small area
such as offices, schools, hospitals, malls, multiplexes etc.. These cells connect to
the service providers network and allow to extend service coverage to indoor
where outdoor signal do not reach well. These cells are available for most cellular
technologies including GSM, CDMA, UMTS and LTE from manufacturers.
Availability of uninterrupted power for the Pico and Femto cells in any case have
to be ensured.
8.0 For making Provision of IBS, there can be several arrangements of
sharing the costs/business models as listed below:
• Carrier/operator pays (traditional model)
– Carrier bears cost of all equipment, cabling and installation
– Customers “lock-in”, through long term contract
– Increase in customer satisfaction
• Enterprise (Buisiness House) pays –
– Enterprise pays for all equipment, cabling and installation
(carrier provides RF source)
– No long term commitment to any carrier
– This model generally requires support of at least 2 carriers on
the system
_______________________________________________________________________________________________ Report of Departmental Committee
24
• Neutral Host – i.e. Malls, Airports
– Bear the cost of CAPEX and project organization.
– Add technical value and remove all performance risk from the
building owner
– Focused ownership of the wireless assets to add value
throughout the life of the project
– Recurring revenue is realized through “lease” of the system to
the carrier(s)
IBS should be part of the specification of the building itself for making
provisions as well as subsequent maintenance. A suitable model is to be evolved
for incorporating in the national building bye-laws as a sub-section (telecom bye-
laws) like fire bye-laws, earthquake resistance bye-laws, energy conservation
bye-laws etc. In high density population areas the in-building solutions like
provision of DAS, Light Radios and femto cell etc. may be considered. The
responsibilities of providing IBS can be shared by building owner, solution
provider and Telecom Service Provider in accordance with the policy of the Govt.
9.0 A conceptual diagram applicable to Indoor DAS as well as outdoor DAS is
placed as Annexure-B.

ii) The high density urban areas to be well served with multiple low
powered BTSs for better spectrum utilization efficiency and increased
battery life of the handsets.
iii) The high powered towers to be avoided with “energy efficiency
analysis process” by installing Large vs. Small cells i.e. low powered
micro cells, pico cells, femto cells.
iv) In uncovered, isolated, scattered and at small locations provide the
outdoor Distributed Antenna System (DAS )

v) Avoid use of large number of antennas by individual operators with
neutral host antenna system. DAS protects the ambiance and
aesthetics
vi) In all multiplex complexes both residential and commercial make
provisions of telecom chambers at ground floor having optical fiber/
copper cable / RF cable connectivity to each and every flat and allow
all the service providers to use the same for extending telecom related
facilities i.e. broadband, mobile, landlines and other services.
vii) The responsibility of providing IBS and telecom chamber at the ground
floor to be shared by building owner, solution provider and telecom
service provider in accordance with the policy of the govt.
viii) The provision of IBS as well as subsequent maintenance should be a
part of the specification of the building contract.
ix) To evolve a suitable model for provision of IBS, incorporating in the
National Building Bye-laws as sub-section “Telecom Bye-laws” like
“Fire-Bye” “Earthquake Bye-laws” and “Energy Conservation Bye-laws”
