Performance and Implementation of Dynamic Frequency Hopping in Limited-Bandwidth Cellular Systems
White Paper This paper evaluates the performance of recently proposed Dynamic Frequency Hopping (DFH) when applied to cellular systems with a limited total bandwidth. The performance evaluation is accomplished by system-level simulations of a system with 12... [10 Jul 2008]
Measurement of the Bandwidth of Helicon Maser
White Paper Radio frequency (RF) magnetoplasmic waves known as helicons will propagate in solid - state plasmas of metals and semiconductors when a strong magnetic field is applied. In Helicon Maser (HM) the helicons are exited by RFs much higher than the... [10 Jul 2008]
A Low-Noise Fast-Settling PLL With Extended Loop Bandwidth Enhancement by New Adaptation Technique
White Paper Extended loop bandwidth enhancement is achieved by the adaptive control on the reference frequency and frequency divide ratio. It enables the loop bandwidth in the speed-up mode to greatly exceed the limit of approximately 1/10 of the channel... [10 Jul 2008]
Load Balancing in Large-Scale RFID Systems
White Paper A Radio Frequency IDentifier (RFID) system consists of inexpensive, uniquely-identifiable tags that are mounted on physical objects, and readers that track these tags (and hence these physical objects) through RF communication. [10 Jul 2008]

On the Relation Between Bandwidth and Robustness of Indoor UWB Communication
White Paper This signal has been characterized by its lower frequency and bandwidth. The paper focuses on the effect of small-scale fading on the throughput of communication systems that operate with different bandwidth within an indoor environment. [10 Jul 2008]
Practical Load Balancing for Content Requests in Peer-to-Peer Networks
White Paper It shows that unlike previous algorithms, it is not tied to the timeliness or frequency of updates, and consequently requires significantly less update overhead. This paper studies the problem of balancing the demand for content in peer-to-peer... [10 Jul 2008]
Reaching the Last Mile With 802.16a Wireless Technology
White Paper The IEEE 802.16a standard provides wireless last-mile broadband access over the frequency bands between 2GHz and 11GHz - a range that enables non-line-of-sight performance. This makes the IEEE 802.16a standard the appropriate technology for last... [09 Jul 2008]
Design Alternatives for a High-Performance Self-Securing Ethernet Network Interface
White Paper This system, called LineSnort, parallelizes Snort using concurrency across TCP sessions and executes those parallel tasks on multiple low-frequency pipelined RISC processors embedded in the NIC. This paper presents and evaluates a strategy for... [07 Jul 2008]
Synchronous Ethernet - A RAD White Paper
White Paper The final difference between conventional TDM-based networks and Ethernet is that the former also transport frequency information, needed for some applications, while Ethernet does not. As more and more traffic is being delivered in Ethernet format... [06 Jul 2008]
