Name: Notes: 1) Answer All Questions, 2) Fill all blanks in what you find suitable. 1- We use Frequency Reuse to increase the network capacity by adopting more users. (A- True, B- False) 2- When propagating wave impinges on an object that is larger as compared to wavelength of the signal, then the wave will face (A-Scattering, B- Diffusion, C- Reflection, D- Diffraction) 3- The time required to send a 2.5 GB file over the different air interfaces is: for 3.5G HSPA, -------- sec for 4G LTE-Advanced, and sec for 5G NR. 4 If the transmit power of a BS is 5 W and the loss factor is y = 3.2, the coverage of region is to be split in half so that micro-cells can be created to accommodate additi users in the region, then the transmit power of the BS of the micro-cell is -W to CCI at the same level as that of the un-split cell. 5- Suppose the acceptable signal-to-cochannel interference ratio (CIR) in a certain cell system is 22 dB. Also, from measurements, it is determined that loss factor is y=3.5. TI the minimum cluster size N is 6- If the path loss Pu in a small city is determined according to Hata model as depicte the figure below. If the transmitted power of the BS is 40 dBm, then the received powe a distance of 30 Km is dBm when operating at 800 MHz frequency. Small and Medium City Path Loss (Hata) 180 170 ***** 160 150 @ 140 2 130 120 110 o-oooo 100 - 100 MHz -- 800 MHz -* 1500 MHz 90 0 10 20 Distance (Km) 30
