Question

1.Explain how nodes exchange wireless signals and specifically how this relates to the wireless spectrum;2. Today, wireless transmission media are commonplace in business as well as residential applications, and their application is growing. This week, we will learn about wireless technology by starting with the fundamentals. How are wireless signals carried? What are the obstacles to successful transmissions and their repercussions? What standards govern wireless transmissions? How do we secure our wireless networks?;3. Traditionally, packet-switched networks carried primarily data and the public switched telephone network (PSTN) carried telephone calls and fax transmissions. Convergence is the use of one network to carry data, voice, and video communications simultaneously. Let?s begin this discussion by identifying and discussing key terms such as IP telephony or VoIP, VoATM, VoDSL, Internet telephony, FoIP, and video over IP.;4. Identify potential obstacles to successful wireless transmission and their repercussions. What can be done to minimize these obstacles?;5. Identify and describe voice over IP (VoIP) applications and interfaces.;6. Describe the quality of service (QoS) assurance methods critical to converged networks, including RSVP and DiffServ.
