ABSTRACT
Long Term Evolution (LTE) is the next major step in mobile
radio communications and is introduced in 3rd Generation
Partnership Project (3GPP) Release 8. It is the last step toward
the 4th generation (4G) of radio technologies designed to
increase the capacity and speed of mobile telephone networks.
With industrial attachment very few radio planning works of
LTE are going on. But because of certain commercial issues
those works aren‟t widely available. Radio network planning
is a very vital step for wireless communication technology. As
standardization work of LTE is approaching the end line, it is
high time to go for efficient radio network planning guideline
for LTE. In LTE just like other cellular technologies, initial
planning is normally guided by various industries and vendors
at their own discretion. They aren‟t likely to disclose their
advancements and findings. That makes the job even more
challenging. As a result, going on with LTE radio network
planning perspective is a well-chosen challenge and a certain
hot topic in the current research arena. In this work, a detailed
LTE radio network planning procedure has been elaborated
which concentrates on nominal and detailed planning
considering possible network implementation in the densely
populated South-Asian city-Dhaka.

1. INTRODUCTION
Whenever new cellular technology is considered for mass
deployment hundreds of its RF parameters go through tuning
process with a view to find out optimum value. But this phase
is time consuming and very costly. So, before commercial
deployment if extensive simulation can be run this tuning
phase can be facilitated in numerous ways. Cost can also be
greatly minimized. That is the benefit of running simulation
before mass commercial deployment. In this sub-continent
LTE is expected to be commercially launched in Q4 of 2012.
All these aim at proper radio network planning of LTE. So,
looking for optimization of the vital parameters in the least
possible time is a very challenging issue which will obviously
help network operators in a greater extent.
the number of resources to be allocated to the PDCCH and
how UEs should be efficiently signaled over the PDCCH is
addressed in [8]. Resource allocation in LTE downlink and
LTE PHY layer simulation aspects have been featured
respectively in [8] and [9]. [10-16] are the 3GPP Technical
Specifications related to this work. Link and system level
The main advantages with LTE are high throughput, low
latency, plug and play, frequency division duplexing (FDD)
and time division duplexing (TDD) in the same platform, an
improved end-user experience and a simple architecture
resulting in low operating costs. LTE downlink transmission
scheme is based on Orthogonal Frequency Division Multiple
Access (OFDMA) - which converts the wide-band frequency
selective channel into a set of many at fading subchannels.
The LTE specification provides downlink peak rates of at
least 100 Mbps and an uplink of at least 50 Mbps. LTE
supports scalable carrier bandwidths, from 1.4 MHz to 20
MHz and supports both FDD and TDD [1] [2] [3]. LTE will
also support seamless passing to cell towers with older
network technology such as GSM, CDMA-One, W-CDMA
(UMTS), and CDMA2000 [1, 2] [4, 5].
Radio network planning being quite a vital step for a wireless
communication technology and as its standardization work is
approaching the end line; it is high time to go for efficient
radio network planning guideline. For the same reason, along
with the fact that in LTE radio network planning just like
other cellular technologies, initial stage planning is normally
guided by various industries and vendors at their own
discretion; they aren‟t likely to disclose their advancements
and findings. That makes the job even more challenging.
The ultimate objective of this work is to come up with the
detailed radio network planning guideline with respect to
Dhaka city. With this mission ahead, in this paper a step by
step method has been followed using radio planning tool
Atoll. The idea was to cover the nominal and detailed
planning stage in detail with respect to Dhaka city.
Performance analysis of the planned network has also been
