An Evaluation of the Effects of Propagation Channels on the Performance of WiMAX (IEEE 802.16-2004)
The purpose of this paper is to evaluate the performance of fixed-WiMAX (IEEE 802.16-2004) operating in seven propagation channel models, by implementing a W...
Fiber Bragg Grating Compression-based Tuning Device for Reconfigurable OADM
In this work a fast Bragg grating-based tuning device, working according to the mechanical compression of the fiber, is demonstrated. The device achieves a...
An Application Server Approach for Number Portability in IMS networks
Number portability (NP) is an important requirement present in most telephony networks. Typically, NP is regulated by local legislation and is inherently a...
