7. What is the wavelength (in m ) of an RF signal that has the center carrier frequency of 1GHz ? II using half wave dipole antenna in this case, what is the length of the antenna? (10 pts) =fCx=fCC=11063108m/s=30m 8. A link budget analysis, for a wireless system operating at 1.9GHz, shows that allowed path loss is 110dB, Calculate the cell size for the path loss using Lp=32.4420log10(fc)20log10(d) fc in MHz, and d in km in the equation. (10 pts) 9. Consider a communication system that uses 16-QAM modulation. It is desired that the system communicates 36Mbits of information each second. What should the symbol rate be? With this symbol rate, how many bits per second can achieve with 256-QAM? (10pts) Consider a communication system that uses 16QAM modulation.
