In spite of the advantages for instantaneous wireless phy/macinformation, what are the pitfalls that a wireless monitoringsystem needs to be aware of?

given the options, i would say your best bet is c. the modem supports up to 56 kbps, which is too low for video streaming. dial up modems use actual phone lines, which only can go up to 56 kbps as that's more than sufficient for traditional phone calls. this is also the reason why when a dial-up modem connects, you hear all those sounds. it's literally using the phone line to establish a connection.

can you include the statments that complete the question ?

you are welcome for my answer it is b⇔⇒⊕
