Title: Communicating with Light: from Telephony to Cell Phones Revision
Title: Communicating with Light: From Telephony to Cell Phones Revision: February 1, 2006 Authors: Jim Overhiser, Luat Vuong Appropriate Physics, Grades 9-12 Level: Abstract: This series of six station activities introduces the physics of transmitting "voice" information using electromagnetic signals or light. Students explore how light can be modulated to encode voice information using a simple version of Bell's original photophone. They observe the decrease of the intensity of open-air signals by increasing the distance between source and receiver, and learn the advantage of using materials with different indices of refraction to manipulate and guide light signals. Finally, students are introduced to the concept of bandwidth by using two different wavelengths of light to send two signals at the same time. Special Kit available on loan from CIPT lending library. Equipment: Time Required: Two 80-minute periods NY Standards 4.1b Energy may be converted among mechanical, electromagnetic, Met: nuclear, and thermal forms 4.1j Energy may be stored in electric or magnetic fields. This energy may be transferred through conductors or space and may be converted to other forms of energy. 4.3b Waves carry energy and information without transferring mass. This energy may be carried by pulses or periodic waves. 4.3i When a wave moves from one medium into another, the waves may refract due a change in speed. The angle of refraction depends on the angle of incidence and the property of the medium. 4.3h When a wave strikes a boundary between two media, reflection, transmission, and absorption occur. A transmitted wave may be refracted. -

It is therefore important to make it cheap and affordable. To be reliable and affordable over the common Public Switched Telephone Network, change is therefore inevitable to keep abreast with the global technological change. It is on this basis that this paper tends to critically review this new technology VoIP, x-raying the different types. It further more discusses in detail the VoIP system, VoIP protocols, and a comparison of different VoIP protocols. The compression algorithm used to save network bandwidth in VoIP, advantages of VoIP and problems associated with VoIP implementation were also critically examined. It equally discussed the trend in VoIP security and Quality of Service challenges. It concludes by reiterating the need for a cheap, reliable and affordable means of communication that would not only maximize cost but keep abreast with the global technological change.

Voip Demystified
Chapter 1 VoIP Demystified Abstract VoIP tools come in many configurations and have been applied with great diversity in libraries. This chapter outlines the technical foundation and adoption patterns of online voice and video calling, and explores how VoIP provides insight into the library technology cycle on a broader scale. Why VoIP? In a 2007 Librarian in Black post, Sarah Houghton-Jan described Voice over Internet Protocol (VoIP) as “not a really sexy technology.”1 In terms of the bleeding-edge con- Library Technology ReportsLibrary Technology cepts Library Technology Reports tends to focus on, I’d have to agree. Web voice and video are old news: Skype’s international popularity is established, voice and video chat proliferate in social media, embedded webcams are com- monplace, and many organizations have made the transi- tion to IP phones in offices and classrooms. The rise of mobile technology is another nail in VoIP’s nonsexy coffin: international cell subscriptions continue to skyrocket and have already far outstripped landline and Web phones.2 www.alatechsource.org Bearing this in mind, you might be wondering why I’ve chosen VoIP as the subject of this report. When Web calling tools began to emerge several years ago, I took on the de facto role of video reference evangelist. I predicted that applications like Skype could transform how librar- ians provided public services over the Web. I imagined video consultations and kiosks that could increase ser- vice point efficiency and humanize the virtual reference 2010 July experience. When I worked at Ohio University between 2006 and 2008, my colleagues and I built an interest- Figure 1 ing, innovative, and frequently hilarious proof-of-concept Hilarity ensues.
