Wireless communication protocols have evolved rapidly since the introduction of 802.11 Legacy over a decade ago. Over the last 10 years we have seen efficiency and performance increases on all fronts‚ which have lead to greater range and faster transfer speeds. With Legacy 802.11 protocols‚ speeds maxed out at around 2 Mbits/sec and indoor range was only about 20 meters. In 1999‚ the 802.11 protocol got a couple of amendments in the form of 802.11a and 802.11b. Both offered higher speeds and slightly

COMMUNICAITONS THROUGH A FOREST CANOPY Clinton Lee Edwards‚ Master of Science‚ 2004 Thesis Directed By: Professor Christopher C. Davis‚ Department of Electrical and Computer Engineering This paper models the effects of the leaves of mature broadleaf trees on air-to-ground free-space optical (FSO) communication systems operating through the leaf canopy. Ecological radiation transfer models are considered and the concept of Leaf Area Index (LAI) is reviewed and related to a probabilistic model. Leaf

Reaction on Reaction Paper The first thing that came to my mind when I have heard about Reaction paper is “What exactly is it?” and before I get an understanding of that‚ I resisted that change. But later‚ when I have studied about it and understood its purpose‚ I have started thinking “Why people avoid change at the first look without an analysis?” The general human tendency is to live in a comfortable zone in which he has lived for quite some time. He draws a circle‚ thinks that circle is his

What risks and safeguards are associated with wireless communication? What is “war driving” or “war flying”? Are you comfortable (or would you use) a wireless “hot spot” to do computer work? What safeguards might you use in accessing an unprotected (public) wireless communications? Are you more at risk using a wireless connection via laptop or a connection via a smart phone? Transmissions over wireless networks can be intercepted by any suitable device within the transmission radius. If a network

The aim of this report is to research wireless antennas and differences between them. Antennas are included 3 types: omnidirectional‚ semi-directional‚ and highly-directional. Any antenna has three fundamental properties: gain‚ directional and polarization. Omnidirectional Antennas. We can use this antenna in a: point-multipoint link‚ warehouse‚ hotspot‚ trade show‚ airport. The omnidirectional antennas transmit a signal in all directions‚ it is known dipole ("non-directional") antenna. The

Wired or Wireless‚ What’s the Difference? The main difference between a wired and wireless data communication infrastructure is the existence of physical cabling. The same‚ or similar techniques are employed for both types of data communication infrastructure in terms of the core elements of essential network services. The basic difference between a wired and a wireless network is self-explanatory. A wired network uses wires to communicate whereas a wireless network uses radiowaves. Let us look

Further‚ to fully use new pedagogical possibilities offered by ICT‚ profound changes in managers’ conceptions of learning and knowledge are required. Technical expertise alone is not sufficient for exploiting new pedagogical possibilities provided by ICT; insofar as ICT is used in the educational system as a purely technical innovation‚ it is not likely that significant pedagogical progress will be achieved. Several cognitive researchers (e.g.‚ Salomon‚ 1997; Salomon & Perkins‚ 1996; Scardamalia
