It monitors the quality of the service by measuring the strength of the WiFi signal at 20 locations.  Every 10 minutes, it receives a sequence of 3 bits from each location. This is essentially a number that indicates how strong the signal is:                                                                                    000   001   010	  011     100  101  110	111                                                                                                                        (000 being low signal and 111 being high signal)                                                                                                     How many bits are received from each location in one day? You may need to use a calculator for this question.

The number of bits in each measurement is called...................................

How often measurements are taken is called .....................
