Evaluation of CRTP performance over cellular radio links

Evaluation of CRTP performance over cellular radio links

IP telephony gaining momentum and cellular telephony having several hundred million users, it seems inevitable that some future wireless telephony systems will be based on IP technology. What we know today as cellular phones may, in addition to telephony and video, have IP stacks, Web browsers, e-mail clients, net-worked games, and so on. If based on IP, telephony service will be much more flex...

Performance Evaluation of TCP Enhancements over Slow Wireless Links

Phase-modulated radio over fiber multimode links.

We present the first experimental demonstration of a phase-modulated MMF link implementing high-frequency digital transmission in a cost-effective solution based on direct detection. Successful subcarrier transmission of QPSK, 16-QAM and 64-QAM data channels for bit rates up to 120 Mb/s through a 5 km MMF link is achieved over the microwave region comprised between 6 and 20 GHz. The overall cap...

Performance Evaluation of VOIP over Multi Radio Multi channel Network

Wireless mesh network is an advanced form of wireless network. A wireless mesh network provides a better solution to problems that often arise in cellular and WLAN. Wireless mesh networks (WMNs) are receiving increasing demand as an effective solution to deploy ISP’s wireless last mile access, such as wireless enterprise backbone networks and other applications. Wireless mesh networks (WMNs) pr...

TCP Performance over Satellite Links

Over the past few years, we have reported on the performance issues faced by TCP/IP based applications on satellite links. Performance is limited by the delay inherent in geosynchronous systems and the probability of bit errors found in any wireless system, including satellite systems. These limitations are becoming more important as new satellite systems ooer much higher data transmission rate...
