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

10) Suppose the wireless client device sends a signal with 0 dBm transmit power, and that both transmitter 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. IMarsh a. Calculate the system margin when the AP is operating in 802.11g mode at 54 Mbps. PTx=0dBm PRx, min = -77 dBm (from table) Lair = 80dBm = Lair - G-G = 80-4-4=72dB G=G = 41B; PAX = PTx - Leh = 0-22= b. Calculate the system margin when the AP is operating in 802.11g mode at 18 Mbps. PRx, min = -86 dBm now PRE = -12dBm =-72dBm M=PRY-PRxmin =-72--77 = 5dB. M=-72--86=14d13 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 15 dB? =-86dBm Pax, min PRx = PRE min = -86 SNRmin=15dB SNR= PRx - Pnoise min Puoise = PRA-SNR min = ~86-15=-101dBm (PTX PRE (PRY.
