Mobile Network Planing Process Case Study - 3G Network

Third Generation cellular networks (3G) were developed with the aim of offering high data rates up to 2Mbps and 384Kbps for stationary and mobile users respectively which allows the operators to offer a multimedia connectivity and other data services to the end customers. In this work we apply techniques to design a 3G radio network, in particular we study the planning and implementation in developing countries, and state of Palestine as a case study. In order to carry a 3G radio network planning for a selected regions, we must follow a roadmap consists of set of phases; First of all, we must determine the region under study on the digitized map in order to obtain some useful information, such as the area distribution; thus using digital maps gives a good clearness for areas classification, land use, land terrain, heights, vectors, etc. Also we must forecast subscriber profile to perform coverage and capacity dimensioning process to achieve nominal cell plan. This paper work studies Nablus as one of the major Palestinian cities. then, subscriber forecast profile is applied in order to calculate the service traffic demand, the capacity and and coverage requirements, this study is carried in corporation with Wataniya which is one of the leading mobile telecommunication service provider in Palestine. For Nablus city we’ve found that 28 sites are required to be installed to meet the given capacity requirements, on the other hand 46 sites are for coverage. At this point we should make decision about how many site will be implemented. In general we have to select number of sites relative to coverage requirement; so to serve Nablus city by 3G services we should implement 46 sites. At final stage, we have to be sure that our proposed 3G network is suitable not only for the first year of running the 3G services over the deployed network, our design takes into consideration the growth of subscribers number and their demands, so periodically, the networking administrators and the network planning department, assess the network current status and upgrade the network to meet the future demands.

Investigating the Organizational and the Environmental Issues that Influence the Adoption of Healthcare Information Systems in Public Hospitals of Iraq

Healthcare information systems (HIS) are an important part of nowadays hospitals as it provides valuable benefits and functionalities for healthcare provision. However, the implementation and adoption of these complex innovations is a challenging task as documented by the literature; therefore, careful planning and consideration to all important factors that influence the adoption process by healthcare staff is required. Governmental reports stated that the usage of HIS systems within public hospitals of Iraq is still low and problematic; that’s why the current study aims at empirically investigating the opinions of healthcare staff regarding the adoption of HIS within public hospitals of Iraq. The current study extended the UTAUT model by integrating additional organizational and environmental factors and for that purpose a questionnaire was developed for obtaining the healthcare staff’s opinions. To the best of our knowledge, this is the first empirical study that utilized the UTAUT model to tackle the topic of HIS adoption in Iraq public healthcare sector. The study was able to explain 33% and 46% of the variance within the behavioral intention and the usage of HIS, respectively. The practical findings of this quantitative study can be helpful for healthcare officials to address the actual challenges related to HIS adoption and to set proper strategies for implementing futuristic HIS projects.

Social networks and its impact on knowledge management

Given the growing interest and popularity of the social network studies at an individual and organizational level, this paper present critical review of literature, identify gaps and appraise current trends and limitations. Nowadays, the topic of social networks is generally viewed from technology perspective; that is to study the adoption and impact of social networking tools and completely ignore the managerial aspect of social networks. In this paper we argue that organization can leverage the power of social networks for performance, growth and eliminate collaboration inefficiencies. This paper also highlights the importance of network analysis at an organizational level and its role in knowledge sharing processes. This paper ends with highlighting the academic and practitioner implications on future research.

Continuous use of social commerce: Its conceptual relation with E-WOM, commitment and trust

The popularity of social media has changed the way of doing business and introduces a new type of commerce known later as social commerce (s-commerce). Within s-commerce, consumer’s loyalty and returning to use have reduced mainly because it is a high competitive environment, which is simply presented by products that proposed and announced rapidly to the market. S-commerce has a magic power called Electronic Word-of-Mouth (E-WOM). E-WOM enables consumers to make a collaboration decision as well as it enable business to reach up their consumers and their network in low cost and short time. Yet, to date, there is limited research that conducted the effect of E-WOM on consumer’s continuous use behavior. Therefore, this study is an attempt to propose a value conceptual model that explains the relationship between e-WOM and continuous use behavior. This study serves not only to clarify the relationship between e-WOM and continuous use, but also to explain the mediating role of trust and commitment in this rel...
