Impact factors for mobile internet applications in the agri-food sectors
Mobile communication and the mobile Internet can provide important opportunities,
economic advantages for enterprises end organisations and support their more efficient operating as they can
be used anytime and anywhere. We can make their wide spread use, innovative effects and advantages
economical if we consider the effect system of technologies and services. The technological, social and
economical complex effect system puts a pressure on the spreading of business applications. The types of
applicable equipment are increasing. According to social aspects there are four player groups:
manufacturers, enterprises, customers and workers. The Internet technology and the Internet network have
become essential communication tools in business processes recently. Using the Internet by means of
mobile appliances increases the possibilities. By studying the business process the expenses, advantages,
disadvantages can well be seen. Nowadays these applications are more and more successful in areas such as
agriculture, different parts of the food industry, extension services, precision agriculture and logistics. It can
be stated that the international and the Hungarian development tendencies of the mobile Internet, the RTD
Programmes of EU help the wide-spread use of mobile services. The rapid development of the Hungarian
domestic mobile market over the last years is the basis for the wide spread use of new broadband mobile
services and applications. This system can contribute to the development of agriculture, enterprises and rural
areas and can support production, commerce, services and product tracing. But for successful applications
we have to consider the impact factors

The impact of organisational culture on WiMax adoption by Saudi SMEs
Although there is some research that examines Worldwide Inter-operability for Microwave Access (WiMax) adoption, the role of the organisational culture by Small and Medium Enterprises (SMEs) has not been studied in the context of the Kingdom of Saudi Arabia (KSA). This paper presents the outcome of a study carried out to examine the impact of organisational culture on the WiMax adoption by SMEs in the KSA. Based on Cameron and Quinn's Organisational Culture Assessments Instrument (OCAI), 63 questionnaires were distributed to different SMEs in Saudi Arabia. The results showed that there is a relatively low level of WiMax adoption by Saudi SMEs. Findings stated that Saudi SMEs are dominated by the clan culture where people are less innovative than the people in adhocracy culture

Survey of Spectrum Sharing for Inter-Technology Coexistence
Increasing capacity demands in emerging wireless technologies are expected to
be met by network densification and spectrum bands open to multiple
technologies. These will, in turn, increase the level of interference and also
result in more complex inter-technology interactions, which will need to be
managed through spectrum sharing mechanisms. Consequently, novel spectrum
sharing mechanisms should be designed to allow spectrum access for multiple
technologies, while efficiently utilizing the spectrum resources overall.
Importantly, it is not trivial to design such efficient mechanisms, not only
due to technical aspects, but also due to regulatory and business model
constraints. In this survey we address spectrum sharing mechanisms for wireless
inter-technology coexistence by means of a technology circle that incorporates
in a unified, system-level view the technical and non-technical aspects. We
thus systematically explore the spectrum sharing design space consisting of
parameters at different layers. Using this framework, we present a literature
review on inter-technology coexistence with a focus on wireless technologies
with equal spectrum access rights, i.e. (i) primary/primary, (ii)
secondary/secondary, and (iii) technologies operating in a spectrum commons.
Moreover, we reflect on our literature review to identify possible spectrum
sharing design solutions and performance evaluation approaches useful for
future coexistence cases. Finally, we discuss spectrum sharing design
challenges and suggest future research directions
