A number of problems are associated with the generation, management and security of PINs, a subset of password. The PINs may be recharge card used by GSM operators or for authentication in ATM. The problems associated with the use of these PINs range from scratching off any of the recharge PIN numbers in recharge card to loss of PIN number or entering invalid number in the case of authentication. It usually takes time for the customer service of the service provider or system administrator to provide convincing solution to these problems promptly when it occurred. PINs generation could seem like simply arranging ranges of number and feeding it into the telecommunication systems such as mobile handsets or ATM to grant access but it requires a specialized and secured way to generate, store and manage it in order to achieve prompt access. This paper focused on the development of database concept to provide solution to these problems by desiging a system by which the PINs generated can be effectively stored and managed so that userss can have immediate access to the PINs if they can provide the identification number on the card. Succintly, the paper discusses the design of a system that generates, manages and secures PINs application using Visual Basic Version 6.0 for designing the front and interface and Microsoft Access 2007 as the database. The system was implemented using real data and the result was successful.

Using Database Management System to Generate, Manage and Secure Personal Identification Numbers (PIN)

Multimedia services are increasing due to necessity of life. As a result, issue of poor quality of services (QOS) and data rate need to be considered for their sustainability. The conventional Multiple Input Multiple Output (MIMO) previously in use can only improve Qos at low data rate while OFDM only reduces data rate. Therefore, this paper aims at investigating the hybridization of MIMO-OFDM with different antenna configurations over Rayleigh fading channel. The binary data are encoded by the convolution encoder. The encoded data forwarded to the mapper are being recorded by the bit inter leaver which are later converted from serial to parallel subcarriers after Quadrature Amplitude Modulation (QAM). The data from Parallel subcarriers 2, 4 and 8 are processed by Inverse Fast Fourier Transform (IFFT). Then cyclic prefix is added to prevent Inter symbol Interference (ISI). The distorted signals are received by 2, 4, 8 antennas, synchronized, cyclic prefix is removed and Fast Fourier transform processes the synchronized signals. The data through different antenna are converted to serial, demodulated and decoded after the de-interleaving. The hybridized system is evaluated using data rates and Bit Error Rate (BER) for 2x2, 4x4, and 8x8 MIMO-OFDM sectorial antenna configurations. The results obtained show that as SNR increases, the data rate also increases for both conventional MIMO and Hybridized MIMO-OFDM, but data rates for the Hybridized MIMO-OFDM are higher than conventional MIMO. Similarly, BER values for hybridized MIMO-OFDM are lower than the values obtained for conventional MIMO. This indicates that Hybrid MIMO-OFDM performs better over Rayleigh fading than conventional MIMO.

Hybridization of MIMO-OFDM Wireless System with Different Antenna Configurations over Rayleigh Channel

Wireless Data Media (WDM) provide data exchange between subscribers who can perform a single tasks in the conditions of active electronic influence. That is why it is important an indicator that characterizes the effectiveness of such WDM is the ability to ensure a given reliability of information reception in the conditions exposure to interference of various origins, including intentional, which characterized by high power spectral density. Effective the direction of counteraction to disturbances is application in WDM of technologies of expansion signal spectrum and code constructions. The purpose of the research is to increase effectiveness of WDM in the conditions of influence of disturbances through ensuring reliability information through the development of methods based on adaptive coding and their using. To develop technology to ensure the reliability of information in WDM on the basis of adaptation of code constructions methods of the theory of management were used, coding, decision making, adaptive systems, optimization, communication, simulation, noise-tolerant coding theory, information theory. The results of the research permit: to ensure reliability of information of departmental radio communication systems under impact of intentional jamming; to quantify reliability of information of departmental radio communication systems under impact of intentional jamming; to choose control parameters in selecting an operating mode of radio communication equipment; on the basis of the developed results to design components of modem equipment for means of departmental radio communication. The results of the study should be used by industrial and research organizations in order to ensure the reliability of adaptive programmed radio stations in conditions of intentional interference.

Abstract Purpose: This article investigates trends in studies on the impact of cultural factors on mobile marketing acceptance. To that end, the article provides a literature review of technology acceptance models and cultural models used in research on mobile marketing. Design/method/approach: This study used qualitative methods to assess the situation of studying cultural factors in the context of mobile marketing acceptance. Various bibliographic sources were consulted, mainly from publications specializing in mobile marketing and cultural theories. These queries were primarily performed through Scopus, one of the main databases of indexed publications related to this topic. Findings: In the field of mobile marketing, interest in the impact of cultural factors on consumer behavior has steadily increased over the past decade. Furthermore, the research showed the role and impact of each cultural dimension on mobile marketing acceptance. Cultural differences lead to differences in consumer behavior toward mobile marketing. Originality/Value: This overview provides a comprehensive discussion and appraisal of cultural theories, a review of technology acceptance theories, and an analysis of previous cross-cultural studies on technology adoption.

Integrated Cultural Theories on Mobile Marketing Acceptance: Literature Review

In this paper we throw a light on the various generations of mobile wireless technologies (1G to 5G) and also presents an overview of 5G technology trends in the wireless technology market.The First Generation were referred to as cellular, which was later shortened to "cell", Cell phone signals were based on analog system transmissions.The wireless industry is busy with the standardization of the 4th generation (4G) cellular networks.The word wide revolution in mobile is changing our lives in term of the way we work, learn and interact. Mobile devices are fast becoming the most pervasive and ubiquitous technology ever invented. We have an overview of the mobile technologies.
