A) The effective aperture of a 144.0cm-diameter parabolic reflector antenna is 6m of the physical aperture area. Compute the gain in dB at 10GHz.

- b) Vodafone decides to use a digital TDMA scheme
that can tolerate a Signal-to-Interference Ratio of
17dB in the worst case. Find the optimal value of
the path lost exponent for an omnidirectional
antenna; assuming i=3 and j=2. Assume that there
are six co-channel cells in the first tier, and all of
them are at same distance from the mobile. Use
suitable approximations.
- c) Draw the table of frequency assignments and
system layouts for a seven-cell repeat pattern and
three-sectored antenna per cell site, using E-GSM
900MHz in which the total number of channels
needs to be divided, assuming that the full spectrum
is available from the operator of the system is used.
In the sixth (6th) cluster, list all the possible
channels that will be assigned to the cells in sector
B?
