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 the wavelength of the signal, then the wave will face (A-Scattering, B- Diffusion, C- Reflection, D- Diffraction) sec 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 this region is to be split in half so that micro-cells can be created to accommodate additional users in the region, then the transmit power of the BS of the micro-cell is --W to keep CCI at the same level as that of the un-split cell. a 5- Suppose the acceptable signal-to-cochannel interference ratio (CIR) in a certain cellular system is 22 dB. Also, from measurements, it is determined that loss factor is y = 3.5. Then, the minimum cluster size N is
