Use inSSIDer at you home (or place of residence where you have other WiFi networks) and observe the signal strength and channel number of your own network and other networks. Make some observations based on the data you collected, like, how do you relate SNR with the distance (from your own location to access points), overcrowded channels (i.e., multiple networks are transmitting using the same set of channels), etc.ī. Include your screenshots from the software. Give the list of available networks/access points including their technical characteristics like channel number, signal (SNR, signal to noise ratio in dB), security, etc. Record the wireless networks available in at least three spots (you may consider going close to a McDonnalds). Use the inSSIDer package installed on your laptop and walk through a shopping centre. Investigate wireless networks available in a shopping centre. Download inSSIDer 3.1.2.1 from the following link:Ī. The software inSSIDer from metageek lets you scan surrounding WiFi networks. Part B – Scanning Wireless Access Points ITECH2300 Describe how AARNet is connected to the Internet in Australia and overseas. Information about the speed and the coverage. Use internet resources and describe the Australian Academic and Research Network’s (AARNet) national and international network with diagram and Theįollowings are the spreading codes and the data that each user wants to send. Four users (U1, U2, U3 and U4) are using CDMA access techniques to transmit data to their respective receivers (U1->R1, U2->R2, U3->R3 and U4->R4). Under what conditions do contention?based media access control techniques outperform controlled?access techniques (i.e., have lower response time)? When might one access method be preferred over another in a network, and why?ĭ.

Give one example each of the controlled access methods and contention based media access methods?Ĭ. What is media access control and why is it important?ī. In relation to access to wireless network (e.g, WiFi), answer the following questions:Ī.
