1. Introduction

The development of telecommunication networks is now growing rapidly. Which initially only carried analogue technology or better known as 1G or Advanced Mobile Phone Service (AMPS), then developed again to the technology using the first digital technology (2G) [1] then 2G technology previously developed again so that data transfer speed is faster known as third generation (3G) digital technology [2]. And until finally found the communication technology with a very high speed of previous generations known as 4G / LTE (Long Term Evolution) [3]

LTE is a continuation of third generation (3G) WDCMA-UMTS technology. LTE bandwidth is from 1.4 MHz to 20 MHz network operator can choose different bandwidth and provide different services based on spectrum. It is also the design goal of LTE that is to improve the spectrum efficiency of the network, enabling the operator to provide more packets of data on a bandwidth [4]

Telecommunication service providers should be aware that consumers want high data access and strong signals. The level of customer satisfaction creates new challenges for telecommunication service providers (operators) to improve and provide the best service for consumers. The quality of a network can be done with a real observation in the field through the measurement of signal quality of a regional 4G LTE service. The method that many do is drive test. Therefore it is very important to test drive on e Node B sites that have implemented 4G LTE technology in North Balikpapan.

4G LTE technology

The LTE architecture consists of two main parts namely the E-UTRAN (Envolved Universal Terrestrial Radio Access Network) and SAE (System Architecture Evolution) which is the heart of the LTE system

e Node B (envolved Node B) is a network interface (LTE) with the user. its ability to perform connection and handover control functions [5]

Operator X

In 1993 Operator X began to explore GSM wireless technology, in the next year, in 1994 PT. Palapa Indonesia satellite is the first GSM network operator in Indonesia to issue SIM cards. Operator X became the largest mobile telecommunications operator in Indonesia with 139.3 million subscribers as of December 31, 2014. The X operator network has covered 288 international roaming networks in 155 countries by the end of 2007

Operator X has become the world's sixth mobile operator with more than 100 million subscribers in one country as of May 2011. Operator X officially launches the first 4G LTE mobile commercial service in Indonesia. Service operator X 4G LTE has data access speed reaching 36 Mbps.

Currently X operators are deploying more than 100,000 BTSs that cover about 98% of the population in Indonesia. As the number 6 mobile operator in the world in terms of number of subscribers. Operator X is the market leader of the telecommunication industry in Indonesia which is now believed to serve more than 143 million subscribers in 2015-2016. In an effort to guide the development of the telecommunications industry in Indonesia into a new era of mobile broadband services, X operators consistently implement 3G, HDSPA, HSPA + technology roadmaps, and Long Term Evolution (LTE) network development. Now operator X develops broadband network in 100 big cities in Indonesia[6]

Operator Y

Operator Y was established in 1967 as the first foreign investment company in Indonesia that provides international telecommunications services via international satellite. Over time, Operator Y evolved into the first international telecommunications company purchased and 100% owned by the Government of Indonesia. In 1994 the Y operator became a public company listed on the Indonesia Stock Exchange and the New York Stock Exchange, the Government of Indonesia 65% and the public 35%

Operator Y gets a 3G network license and introduces 3.5G services in Jakarta and Surabaya. In 2009 Qtel purchased 24.19% of B series shares from the public to become a majority shareholder of Y operator with 65% ownership. In the same year operator Y obtained an additional 3G frequency license from the Ministry of Communications and Informatics and won a tender for a government-run WIMAX license.

In 2013, operator Y held commercialization of 3G network at 900 MHz frequency. The following year Indosat launched 4G service launch and service at 900 MHz with speeds up to 42 Mbps in some major cities in Indonesia.[7]

2. Methodology

Drive test mechanism

Drive Test is a measurement process of mobile communication system on the radio waves side in the air, from the direction of base stations to MS or from MS to BTS by using mobile phones specially designed for measurement. The purpose of the implementation of Drive Test is to measure signal quality and fixes problems associated with the signal.

Drive test also has a special purpose within network optimization:

  • Knowing whether coverage at the time of planning or planning the same as the actual situation in the field.

  • To look for poor coverage or areas that have power receive low signal.

  • Find out whether the network parameters in the field are appropriate with the reality at the time of planning and optimization.

  • Knowing network performance after the changes are made, such as the addition or reduction of BTS (Base Transceiver Station).

  • To know the performance of other carrier networks or Benchmarking.

  • Know if there is interference from neighboring cells.

  • To search for RF (Radio Frequency) issues related to the Drop Call or Block Call [8].

Reference signal received quality (RSRP)

RSRP is the average power on the resource element that carries the reference signal in the subcarrier. UE (User Equipment) measures the power of many resource elements used to carry the reference signal and then calculated the mean in one bandwidth.

Table 1

RSRP Signal Strength [10].


RSRP Value Signal Strength
-80 dBm Excellent
-80 dBm to -90 dBm Good
-90 to 100 dBm Mid Cell
< = - 100 dBm Cell Edge

Pilot pioneer

Pioneer is a flexible laptop-based diagnostic tool for indoor and outdoor assessment of all major wireless networking technologies (GSM/CDMA/UMTS/TD SCDMA/HSDPA/Wi-Fi/WIMAX/LTE). It is a user-friendly, highly-scalable solution that accelerates returns on your network investment. Pioneer can display map-based data in real time and simultaneously export said information to a server for further analysis. The data it collects reflects user perceptions, enabling engineers to maximize subscriber satisfaction and your bottom line.

Below, features of Pilot Pioneer:
