Abstract With an integrated framework, this paper aims to
analyze user perception and acceptance toward long-term
evolution (LTE) services,focusing on factors that may influence the intention to use. We conducted a web-based
survey of 1,192 users to test our research model. We
employed structural equation modeling (SEM) as the analysis method. The results of the integrated model analysis
indicate that system satisfaction is a core determinant of
intention to use LTE services. The model also found that
other factors, includingperceived usefulness and system and
service quality, significantly affect intention to use these
services. In addition, both perceived adaptivity and processing speed significantly influence perceived usefulness and
service quality, respectively. These factors also play key
roles in determining users’ attitudes. This paper is of value
to researchers and engineers designing and improving LTEservices for use via mobile phones.

1 Introduction
3GPP Long-term evolution, normally called LTE or 4 G LTE
in commercial markets, is a wireless communication standard
that is used across the world [1, 2]. It is designed for the

exchange of data using mobile systems including mobile
phones and related communication systems. LTE provides
higher speed and larger capacity than 3 G mobile communication standardsincluding WCDMA or UMTS. Many people
have used LTE service via their mobile phones. In South
Korea, the number of LTE users has already exceeded four
million [3]. Engineers and researchers who are interested in
mobile communication systems or services have focused on
factors that affect user satisfaction and perception to provide
better service. In particular, because LTE service is used inmobile phones, researchers have started to find differences
between traditional 3 G and 4 G LTE in mobile phones with
related services and systems.
Although LTE services and their mobile phones are highly distributed and developed, LTE users have not been well
studied. Today, mobile phones play a crucial role in our
daily lives because they offer various types of service [4].
For instance,mobile phones allow people to use mobile
banking systems [5–7], learning [8, 9], and internet and
intranet [10, 11]. This growth of mobile devices and technology has motivated research on the use of mobile services.
With this perspective, this study aims to investigate factors
that affect user perceptions of LTE and mobile phones, and
to propose a user acceptance model of LTE service. To dothis, the unified theory of acceptance and use of technology
(UTAUT) model and the technology acceptance model
(TAM) were adapted and used to compose a new predictive
model [12]. Using the new model, this study tries to forecast
and explain user acceptance of LTE service. Also, to better
predict user motivation to utilize LTE services, factors including perceived adaptivity, perceived processingspeed,
system and service quality, and system satisfaction were
integrated into the model. The present study aims to provide
an integrated and fundamental model for explaining user
acceptance of and motivation to utilize LTE services. This
study has two subjective goals: (1) explore the feasibility of
