a) determine the critical distance for the two-ray model in an urban microcell (ht=10m, hr=3m) and an indoor microcell (ht=3m, hr=2m) for fc=2GHz. What are the practical implications of your obtained values
b) Consider an indoor wireless LAN with fc=900MHz, cells of radius 100m, and none-directional antennas. Under the free-space path lost model, what transmit power is required at the access point such that all terminals within the cell receive a minimum power of 10uW. How does this change if the system frequency is 5GHz.
c) The transmission power of a wireless system is 40W, under a free-space propagation model. 1) what is the transmission power in unit of dBm 2) The receiver is in a distance of 1000m, what is the receiver power, assuming that the carrier frequency fc=900MHz and Gt=Gr=0dB 3) Express the free space path lost in dB

Two-Point Mapping The general strategy used to determine the genetic distance between linked genes is to: 1. Make all of the genes of interest heterozygous in an individual or strain 2. Examine the gametes produced in the heterozygous individual(s) Using our example above. You have two pure-breeding lines of plants, one with green seeds and short height (GG tt) the other with yellow seeds and tall height (gg TT). You cross the two strains to make the genes heterozygous. What...
