Nowadays, users are relying on mobile service ecosystem for their daily life, while there is a lack of support for users to efficiently migrate their tasks across different terminals. Furthermore, the same application running on different terminals may even have different layouts to guarantee the user experience, which makes the migration more difficult. To facilitate the switching among multiple...
Growing mobile data usage has led to end users paying substantial data costs, while Internet service providers (ISPs) struggle to upgrade their networks to keep up with demand and maintain high quality-of-service (QoS). This problem is particularly severe for smaller ISPs with less capital. Instead of simply upgrading their network infrastructure, ISPs can pool their networks to provide a good QoS...
Internet service providers (ISPs) struggle to invest in upgrading their networks to catch up with growing mobile data demand, while users have to face significant data overage fees. Pooling ISPs' network infrastructures can potentially enable better user experience and lower prices. For example, Google recently launched a cross-carrier MVNO (mobile virtual network operator) data plan called Project...
A compatible low-noise multi-phase voltage controlled oscillator is demonstrated in this paper. A compatible current steers are used to reduce the gain of VCO. The cascade structure of inverter is used to suppress the intrinsic noise and power supply noise. By increasing the output resistance of current steers with the cascade structure, the supply noise is suppressed. A modified inverter delay stage...
This paper reports on the authors' attempts for realtime lecture delivery between Japan, Thailand and Malaysia using a redundant network consisting of a high-speed internet satellite (WINDS) and a terrestrial line (JGN2plus). The feasibility of multi-site real-time distant lecture system has been confirmed in several lecture delivery experiments. Also, the robustness of system has been proved by near...
An investigation on the latent advantages of switched beamforming combined with cell-site diversity in the context of millimeter-wave local multipoint distribution service (LMDS) systems is presented in this paper. Rain attenuation is the major fading mechanism in such systems over the frequency range above 25 GHz. A moving rain cell is randomly generated in an LMDS network to analyze the system performance...
