Location Based Service (LBS) 'as a kind of emerging applications based on the mobile Internet technology, is one of the most potential mobile value-added services. With the mobile network positioning technology and electronic map platform, it provides position information of the traffic, tourist attractions, shopping center etc. to users. This paper studies on the background, significance, types and...
This paper analyzes the changes of the operators' competitiveness structures under the background of 2/3G network convergence. First, it builds the operators' competitiveness structure model from dynamic perspective. Second, it analyzes the relationship between capability and resources of telecom operators and its impact on enterprises competitiveness in the light of resources and capacities. Finally,...
The deployment of WLAN emerged weaknesses in security and manageable, controllable characters, which also limited wireless city plans to discover a successful business model. The paper analyzes the effort of choosing WAPI from three key factors: firstly, the infrastructure of WAPI improves WLAN's authentication system; secondly, the certificate authority of WAPI adapts to flexible network construction...
The application of 3G will provide an opportunity for the development of M-Commerce. In this paper, we analyzed the development tendency of M-commerce and the advantages of 3G, and finding that the launching of 3G services will greatly contribute to the development of M-Commerce in China. We also found that M-Commerce would become the development emphases of 3G, basing on the survey of the mobile...
This paper finds that, in the process of marketization, network-type service monopoly enterprises tends to pursue their profit goal through product and service differentiation, by lowering the quality of universal service and increasing the price and quality of high-paid services, which usually expel customer from universal service to more expensive service, hence reduce the social welfare. After...
In the current networked globe, Web has proved itself the most advanced and effective way of communication. During early development of the Internet there was a little notion that the Web development will hit this Internet so hard one day. In such a short time, Web 2.0 and now Web 3.0 has created great heights in the face of Internet industry. The distance from Web 1.0 to Web 2.0 has been covered...
Since the traditional innovation models based on the proprietary system and internal R&D are reaching their limits, the open innovation model has been developing steadily in recent years, especially in the ICT sector which is characterized by a strong segmentation of skill-sets among firms. Business drive has taken the place of engineering drive in telecom market, which indicates that business...
NGN is an increasingly becoming the market reality of the information and communication sector and hence has put forward many challenges to the National Regulatory Authorities of the whole world. In this period of migration from the legacy networks to the NGN, every regulator has adopted an approach different from other depending upon the regulatory environment in which they operate and the future...
In this paper, packet error rate (PER) of Zigbee (IEEE 802.15.4) under the interference of radio frequency identification (RFID) is analyzed by establishing a mathematical model of the mutual interference. This proposed model takes PHY (such as the channel model, the transmitted power, the spreading and the modulation) and MAC (such as CSMA/CA, the traffic load and the packet format) into account...
The performance of Bluetooth under the interference of RFID is investigated. A mathematical model is proposed to quantify the performance degradation of Bluetooth. The proposed model carefully takes PHY (i.e., the channel model, the transmitted power, the distance and the modulation) and MAC (i.e., the frequency hopping, the packet format and the traffic load) into account. Packet error rate (PER),...
This paper highlights the discrepancies in the current structure of the policy & regulatory framework of spectrum management. Some driving forces for the spectral reforms have also been discussed here. Innovative techniques for spectrum management and also to increase the spectral efficiency have also been proposed for the harmonization and standardization of this sector. This paper also discusses...
This paper puts forward the model of cooperation between mobile operators and the SP (service provider) enterprises. Through the detailed comparison between the "stimulate - reaction" regulation strategies and its sequent effect of implementation, it points out the disadvantages of the current regulation policies. In conclusion, on the basis of empirical analysis and service quality theories,...
