## 6 Conclusions, Limitations, and Future Research Directions  
The analysis results show that the causal relationships between the proposed facets of ITOE framework are tenable and consistent with expectations. Fifteen determinants were identified from a pilot qualitative study and were further validated by the empirical analysis. This study verified that the internal users' intentions will certainly affect the SME's adoption of broadband mobile applications; this is also in line with our hypothesis. These findings provide several valuable insights for both SMEs and broadband mobile applications providers. For the SMEs, this study suggests that the characteristics of broadband mobile technology are largely boosting the innovation of mobile applications; this can bring considerable benefits and advantages for business. It is important to ensure the compatibility between the new applications and the inner process and systems of an enterprise before the adoption. The adoption preference of business partners and clients should be taken into account. The possibility of a long-term partnership with external IT supporting resources should not be ignored. Apart from the above, issues of human resources are absolutely crucial to consider. Commitment and resources devoted from high-level management, the enhancement of employees' knowledge, and favorable processes of continuous learning and knowledge sharing will be the cornerstones of successful adoption. Most importantly, the enterprises must fully communicate with internal users to be willing to join the process together and instill the habit of using the new applications with personal mobile devices. The SMEs should consider and prioritize the determinants from the results of this study while determining broadband mobile applications are crucial to the growth of the business. For application providers, apart from the functions and effectiveness, a thorough data security and privacy protection strategy of products and services must be developed. Providing a trial version or a free trial period would be very helpful in attracting clients and customers to try the application. Furthermore, it is indispensable to provide sufficient after-sales services and timely support to win SME clients. These determinants from the results of the study should fairly improve the SMEs' approach to the adoption of broadband mobile applications, spurring growth for both providers and SMEs. For the theoretical implication, this study makes contributions to the research of the innovative mobile technologies and applications adoption by SMEs. Internal users' context was added to the TOE framework and then to an ITOE model that has been proposed in this study. The study also incorporates employees' personal considerations and provides a comprehensive view and extensive insights. Feasibility is confirmed by the results of this study. It is expected to serve as a practical reference for future studies. Overall, both SMEs and broadband mobile application developers should consider the results of the significant determinants, demonstrated to be important factors that could improve the adoption process. In terms of limitations and future research directions, although the results of this study are expected to be constructive for SMEs of both domestic and foreign countries under similar conditions, there may still be issues in individual industries and countries. This study has strived to obtain an in-depth understanding by qualitative interviews and a comprehensive sample collection process. Considering that the respondents of SMEs may not have sufficient expertise for the use of specific broadband mobile technology and its applications, complicated broadband mobile applications are indeed a real challenge for SMEs; however, this study is focused only on the conventional usage of broadband mobile applications. Future research could further explore the adoption of broadband mobile applications in specific settings.
