SPECTRUM MANAGEMENT
#. Radio Frequency (RF) Spectrum encompasses the
entire range of electromagnetic radio frequencies used
in the transmission of voice, data, and images.
#. The RF spectrum is also important resource for
economic growing of a country.
#. It is a limited and finite national resource and
hence it requires very precious utilization in the most
efficient manner.
3
SPECTRUM MANAGEMENT
#. For the requirements of modern communications
with increasingly higher data rates wireless is the only
option.
#. The requirements of captive applications are also
growing.
#. All these have resulted in greater demands on the
already scarce RF spectrum resource.
4
Spectrum Uses
1. Military & Police applications,
2. Telecommunications for fixed/mobile wireless
access,
3. Transmission and satellite networks;
4. Broadcasting:
5. Radio and television,
6. Emergency/disaster management;
7. Meteorology;
8. Civil aviation;
9. Radio navigation;
10. Aeronautical and maritime communication;

SPECTRUM ALLOCATION
Bangladesh Telecomm Regulatory Commission
(BTRC) is responsible for frequency management,
assignment and its use. Sometimes in the past,
frequency was assigned just upon application without
giving any consideration to any other relevant factor.
A National Frequency Allocation Plan (NFAP) has
been formulated to address these issues.

Spectrum Division
#. The main task of Spectrum Division is to assign
frequency under the guidance of National Frequency
Allocation Plan.
#. There is a Spectrum Management Committee
consisting 13 members from concerned Ministries,
Armed Forces Division, Bangladesh Radio,
Bangladesh Television, Shipping Department, and
Civil Aviation Authority & Law enforcing Agency.
9
Spectrum Committee
#. The spectrum committee has been formed under
the section 56 (1) of Bangladesh Telecommunication
Act 2001.
#. The Spectrum Management Committee only
recommends to the Commission for assigning
frequency from different bands to various
organizations.
10
Spectrum Committee
#. Upon recommendations, the Spectrum Division
has assigned frequencies to mobile operators, PSTN
operators, Broadband Wireless Access service
providers, satellite TV channels, Aeronautical and
Maritime communications, Private Mobile Radio
(Walkie Talkie), Internet Service Providers and other
Government organizations.

Tasks of Spectrum Division
The division does the following works:
• Spectrum Planning.
• Spectrum Assignment.
• Frequency revalidation.
• Issuing NOC for importing radio equipments.
• Issuing import permission of the mobile handsets.
• Issue Amateur Radio, TV, FM Radio and
Community Radio License.
• Issue Maritime, Aeronautical License.
• Issues related to ITU.
12
Spectrum Division
#. To manage all such important activities, the
Spectrum Division conducts expansion and
appropriate training of its personnel.
13
National Frequency Allocation
Plan
#. Different frequency is used by different
technologies, there are possibilities of interference. In
order to avoid this, country has its own frequency
allocation plan depending on technology based
spectrum management. This plan is known as
National
Frequency
Allocation
Plan.
#. After BTRC was established, NFAP was prepared
by UK based consulting firm ‘Interconnect
Communication’ in the year 2004.
14
National Frequency Allocation
Plan (NFAP)
#. The 9 KHz to 1000 GHz frequency band has been
reserved
for
various
services
in
NFAP.
#. According to ITU Radio Regulation, currently
frequency is allotted to the applicant after consulting
NFAP.
#...Presently, NFAP is from 9 KHz to 275 GHz.

Spectrum Interferrence Handling
•
•
•
•
Interference information submit to BTRC.
BTRC checks it by intelligent activity.
Warns and stops the unauthorized user.
Allocate a new frequency to the user.
• Nobody can use any spectrum without written
permission of BTRC.
