Answer the following questions in relation to Wireless networks. [5 Marks] a. Give one example for infrastructure and no- infrastructure wireless networks. (1 Mark) b. Assume two devices placed at 30 m and 50 m from a Wi-Fi access point. The first device experiences a signal strength of 1 mW, while the second one experiences 0.1 mW respectively. (2 Marks) i. Explain why the second device experiences lower received signal strength. ii. If both devices experience a noise level of 10 W, which device achieve higher data rate? Justify! c. In which cases the wireless device can operate at higher modulations order? How this impact the device throughput? (2 Marks) Answer the following questions in relation to Wireless networks.
