Current IEEE 802.11 wireless local area network (WLAN) standard products can provide up to 54 Mbps raw transmission rate, while non-standard WLAN products with 108 Mbps have already appeared in the market, and the next generation WLAN will provide much higher transmission rates. However, the medium access control (MAC) was designed for lower data rates, such as 1–2 Mbps, and it is not an effici...

Possible Difference in the Sympathetic Activation on Extreme Dippers With or Without Exaggerated Morning Surge To the Editor: We read with great interest the report by Grassi et al1 that sympathetic activation is responsible for the nocturnal blood pressure (BP) dipping status in hypertensive subjects. We agree that reverse dipping status is characterized by a marked sympathetic activation. We ...

Cloud servers are generally used for data storage and remote office activities, but it can be applied gaming purposes, where cloud paired with virtual machines platform that accessed by users via an internet connection. This makes the device user no longer needs to process resources because workload is carried out on server. The author designs a system using Google as server parsec optimizer at...

Bandwidth-intensive applications compete directly with the operating system’s network stack for CPU cycles. This is particularly true when the stack performs security protocols such as IPsec; the additional load of complex cryptographic transforms overwhelms modern CPUs when data rates exceed 100 Mbps. This paper describes a network-processing accelerator which overcomes these bottlenecks by of...

The power consumption of wireless access networks will become an important issue in the coming years. In this paper the power consumption of base stations for mobile WiMAX, fixed WiMAX and UMTS is modelled. This power consumption is evaluated in relation to the coverage. For a physical bit rate of 2 Mbps, a power consumption of approximately 5600 W and a range of 1 km is obtained with UMTS. Fix...

During the design of ABR tra c management at the ATM Forum, we performed several analyses to ensure that the ABR service will operate e ciently over satellite links. In the cases where the performance was unacceptable, we suggested modi cations to the tra c management speci cations. This paper describes one such issue related to the count of missing resource management cells (Crm) parameter of ...

In a SONET/SDH network the frame alignment is an important function. This paper presents a component that realizes it and the section layer functionality in a SONET/SDH network. The user can choose between STS-1/STM-0 at 51.48 Mbps or STS-3/STM-1 at 154.44 Mbps operation. There are some components to do frame alignment [1] but here we present a new component with a wider range of functions. The...
