Arianna Wants to Implement 802

Arianna wants to implement 802.11b for a series of hotels that her employer won the contract on. Her boss says that one of the customers was concerned that if TCP error checking was part of the configuration, the network would be slower. Arianna pauses, and explains …. ?

A) TCP error checking effectively speeds up the network. Since there will be fewer retransmissions the speed will surpass the speed of the wired network.
B) The resulting speed will be about 6Mbps. Since the Ethernet in the hotel is 10Mbps, accounting for several users at the same time, a throttle speed makes sense.
C) Error checking is part of the TCP protocol already. Network speed measures bits, the overhead that gets delivered are bits too.
D) Her boss is correct, and the whole project should just get scraped. Let someone else deal with these difficult customers.
