Question

A laptop computer communicates with a router wirelessly, by means of radio signals. The router is connected by cable directly to the Internet. The laptop is 7.2 m from the router, and is downloading text and images from the Internet at an average rate of 242 Mbps, or 242 megabits per second. (A bit, or binary digit, is the smallest unit of digital information.) On average, how many bits are downloaded to the laptop in the time it takes the wireless signal to travel from the router to the laptop?

Explanation / Answer

Wireless signal travels at the speed of light, being an EM wave.

time taken : 7.2/3*108 = 24 ns ; nano sec.

and the bits downloaded in this time are :

242*106 bits in 1 sec

so in 24ns : 5.8 bits.. appx 6 bits
