Bluetooth uses licensed frequency range for its operation (True / False) Part B (5*2 = 10 points) 11. Check to see if the following set of chips can belong to an orthogonal system. [+1, +1] and [+1,-1 12. Compare the range of 16-bit addresses, 0 to 65,535, with the range of 32-bit IP addresses, 0 to 4,294,967,295 (discussed in Chapter 4). Why do we need such a large range of IP addresses, but only a relatively small range of port numbers?
