This paper introduces a multiband base-station antenna to provide multiple communications services. There is growing need for multiband base-station antennas for mobile communications to serve existing 2nd and 3rd generation systems and to provide emerging 4th generation communication service as well as WiFi. For example, cellular, PCS, and especially WCDMA service are currently widely used in Korea, and 4th generation service (WiBro and LTE), introduced in 2011, will have to operate in parallel with existing services. The proposed multiband base-station antenna can provide a single/dual/triple or more multiple services using dual-polarization (±45° linear polarizations) according to the requirements of the service provider. This antenna has a shared aperture, having several array antenna sets for multiple services (Band 1: cellular service in 0.824~0.894 GHz, Band 2: PCS, WCDMA, and WiFi in 1.920~2.170 GHz, Band 3: WiBro and WiMAX in 2.300~2.400 GHz, and Band 4: WiMAX in 5.150~5.850 GHz). This antenna can be helpful for reducing base-station operating expenses and to create a clean urban landscape by minimizing the number of base-station antennas, which are increasing rapidly.

Knowledge Articulation

An e-business new product development (NPD) knowledge articulation model is built from the interdisciplinary empirical and theoretical literature. The model is intended to facilitate a case study of a large multinational mobile communications services/products company (with team members in Europe, Asia and Australia). The NPD teams include subject matter experts that function as a community of practice, electronically collaborating in a virtual context. The knowledge created and shared in the NPD teams involve various unknown levels of tacit and explicit ideas, which are difficult to understand or assess. The goal of the research is to build a tacit knowledge articulation framework and measurement construct that can be used to understand how a successful (or unsuccessful) NPD team operates, in terms of knowledge innovation and productivity. Complex issues and controversies in knowledge management are examined to clarify terminology for future research.

Real World Datasets

The emergence and widespread use of mobile Internet technology has led to many different kinds of new mobile communications services, such asWeChat. Users could have more choices when attempting to satisfy their communications needs. The ability to predict the way in which users will use new mobile communications services is extremely valuable to mobile communications service providers. In this work, we propose a method for predicting how a user will use a new mobile service. Our scheme is inspired by the evolutionary game theory. With large-scale real world datasets collected from mobile service providers, we first extract the benefit-related features for users who were starting to use a new mobile service. Then we design our training and prediction methods for predicting potential users. We evaluate our scheme using experiments with large-scale real data. The results show that our approach can predict users’ future behavior with satisfying accuracy.

Modern business, characterized by growing user expectations and intense competitive relationships requires companies to survey customer satisfaction in a continuous manner. Customer satisfaction increases loyalty, fosters repurchase intention, enhances positive reaction and reduces the number of complaints. Customer satisfaction survey on regular basis is one of the prerequisites for creating adequate offer that meets customers’ expectations and ensures their long-term loyalty. Namely, loyalty as a long-term preference for the company’s products and services assumes customer who is willing and able to maintain interact with the brand offered by the company. Essentially, brand loyalty implies that the customer, based on the information and his beliefs, prefers the brand that is superior to the others. The main objective of this paper is to examine the level of customer satisfaction with specific aspects of services provided by mobile operators in the Montenegrin mobile communications market. Customer satisfaction with specific aspects of services available in the mobile communications market in Montenegro has been surveyed in 2013. This survey covered 788 respondents, and their levels of satisfaction have been examined using the survey method along with the statistical analysis of a number of variables. The first part of questionnaire consisted of questions aimed at collecting data on demographic characteristics of respondents, i.e. users of services of mobile operators, while the second part consisted of questions related to the basic research subject, i.e. the levels of customer satisfaction with the mobile communications services provided by mobile operators in Montenegro.The presented research method and recommendations provided in relation to the process of surveying customer satisfaction in terms of methodology may be important also for mobile operators operating beyond the Montenegrin market, enabling them to raise the quality of their customer satisfaction surveys and to improve thereby their own business.
