A Wi$-$Fi gateway supports $802\mathrm{.}11$g$,$ achieving $54$ Mbps radio data rate. The gateway radio

transmitter has a utilization of $\backslash$rho $=0\mathrm{.}2.$ The average data frame contains $800$ B$.$ The average number of frames

stored at the gateway is N $=1/4.$

A$)$ Compute X$,$ defined as the average time a frame remains in transmission $[$pt$.10].$

B$)$ Compute $\backslash$lambda $,$ defined as the frame arrival rate at the gateway $[$pt$.10].$

C$)$ Compute T defined as the average total time a frame spends in the gateway $[$pt$.10].$
