Wireless Building Control Communications Using WLAN Mesh

Route Discovery


• On Demand route discovery
• Triggered whenever a source node wants to communicate with other node for which there is no entry in the former’s routing table.
• Source node broadcasts a RREQ (Route REQuest) across the network. Nodes receiving RREQ will update their information by setting up backward pointers to the source node in their route tables (Reverse Route set up)
• A RREP (Route REsPonse) packet is sent back to the sou ....etc

Antenna Design for WLAN
Abstract
Antenna is a vital component in wireless application systems. The microstrip antenna can be used for wireless applications as it has features such as light weight, easily mounted and it is easy to mass produce. Although there are many features that suits well for microstrip antenna to be deployed for wireless applications, there is a very serious limitation where it has a very narrow bandwi ....etc

Abstract—This paper presents a novel approach to building a WLAN-based location fingerprinting system. Our algorithm intelligently transforms received signal strength (RSS) into principal components (PCs) such that the information of all access points (APs) is more efficiently utilized. Instead of selecting APs, the proposed technique replaces the elements with a subset of PCs to simultaneously improve the accuracy and reduce the online computation. Our experiments are conducted in a realistic WLAN environment. The results show that the mean ....etc

Enterprise FMC and the T-Mobile HotSpot@Home service
In recent years the features of dual-mode devices (cellular voice and data clients with additional Wi-Fi
radios) have grown increasingly sophisticated. The burgeoning capabilities of these devices have attracted
the attention of IT staff at enterprises and universities with campus environments because of potential
synergies with already installed wireless LANs. More specifically, the potential exists for a user to carry a
single device that leverages Wi-Fi coverage where cellular ....etc

Abstract


This paper outlines some of the technical challenges that must be met, particularly with respect to handset radio design, that will allow coexistence between Cellular and WLAN modes of operation. Various aspects of coexistence are considered, such as the demands of the RF architecture, interference issues, chip set fabrication and cost issues. Conclusions are then drawn as to the defining aspects of WLAN and Cellular convergence ....etc
