Which of the following data network would you implement if you wanted a wireless network that had a relatively high data rate, but was limited to very short distances?

A.
Broadband personal comm. Seivice (PCS)

B.
Broadband circuit

C.
Infrared

D.

E.

Explanation:
A good example of the range of an infrared is a television remote control or a garage door opener. Infrared networks are capable of high data rates, but they are limited in the distance between the infrared points, and also by the fact that a line of sight between the nodes is usually required.
Incorrect answers:
A: Although these are both wireless methods, the data rate capabilities are somewhat limited, especially when compared to infrared links.
