Solve and show work on paper. Attached are examples please solve same way thanks.

PTX 10) Suppose the wireless client device sends a signal with 0 dBm transmit power, and that both transmitter Leh - (Lair ) and receiver have 4 dBi gain antennas. Ignore losses in antenna wires. Let the client device be at a distance from the AP so that the air channel loss is 80 dB. Calculate the system margin when the AP is operating in 802.1 1g mode at 54 Mops. PTX Odom PRX, min = - 77 dBm ( From table) Lair : 80 d Bm G = G2 = 41Bi Leh = Lair - G-G2=80-4-4 = 72dB PAX = PTX - Leh = 0- 72 =- 72 dBm b. Calculate the system margin when the AP is operating in 802.1 1g mode at 18 Mops. M PAX, min = - 86 dBm now M = PRX - PRXMin PAX = - 72 dBm =-72--77 min M =-72--86= 14613 =5 d B. c. Suppose the AP is operating in 802.11g mode at 6 Mops, and that the received power is equal to the receiver sensitivity (i.e., the system margin is exactly o dB). What is the maximum noise floor if we are to maintain the SNR at or above 15 dB?

Ignore losses in antenna wires. Let the client device be at a distance from the AP so that the air channel loss is 75 dB. a. Calculate the system margin when the AP is operating in 802.1 1g mode at 54 Mbps. b. Calculate the system margin when the AP is operating in 802.1 1g mode at 18 Mops. c. Suppose the AP is operating in 802.11g mode at 6 Mbps, and that the received power is equal to the receiver sensitivity (i.e., the system margin is exactly 0 dB). What is the maximum noise floor if we are to maintain the SNR at or above 20 dB
