In this paper, we report on a mobile broadband wireless access (MBWA) system field trial with Fast Low-latency Access with Seamless Handoff Orthogonal Frequency Division Multiplexing (FLASH-OFDM), which was carried out in a suburban area of Sendai city. This paper focuses on coverage and downlink throughput performance, which are the most important criteria for assessing broadband wireless data communication...
In mobile wireless ad-hoc networks, data messages are forwarded by each intermediate node through a wireless communication link which is less reliable than a wired communication link. For achieving reliable data message transmissions, two main methods have been proposed; BEC (Backward Error Correction) with conditional retransmissions of data messages and FEC (Forward Error Correction) with unconditional...
The rapid increase and proliferation of mobile wireless technologies has led to the rise of new problems that fall under the umbrella of challenged networks, namely, intermittent network connectivity. This diversity in wireless devices, along with their convergence, has granted users access to multiple heterogeneous networks available in parallel. Nowadays, a user generally expects to be connected...
In this paper, we report the first fully bidirectional wireless data transmission of IEEE802.11a Wireless Local Area (WLAN) signals over fibre using uncooled directly modulated lasers thus providing a low cost solution. A successful connection of IEEE802.11a was established between a mobile unit and the remote base station (BS) which in turn was connected via an optical fibre to the wireless access...
Heterogeneous wireless environments are now a reality in many urban areas. Designing and deploying a wireless network in such an environment is complicated by the unpredictable propagation paths of radio signals and by the unpredictable behaviour of the network users themselves. Network simulation and modelling can be used to assist in the design process. However, in order for simulation models to...
