(a) A cellular system using a cluster size of seven is operated with 660 channels, 30 of which are designated as control channels. Answer the followings, given the system's user density of 9000 users/km2, cell radius R of 0.5 km and the area of a cell equals 2R2 km2. Assume each user makes an average of one call every 2 hours and each call lasts 2 minutes during peak hours. Calculate the number of voice channels per cell. Calculate the average number of users in one cell. by half of What is the traffic intensity per cell? If the traffic intensity increased its value, describe the effect on the system capacity? [5 marks] Based on the number of voice channels found in (1), find the blocking probability. Erlang B Traffic Table is given in Appendix. [5 mark] Based on the number of voice channels found in (1), find the number of users that can be served in a cell, if grade of service (GOS) of 2% offered by Erlang B formula is chosen. What is the percentage of difference to that found in (2)? Justify your answer. [10 marks]Window= 1. 2. 3. 4. 5.
