The one way bandwidth available to a single operator in the telecommunication system is 12.5 Mhz with a bandwidth of 30 Khz and 21 control channels. Calculate the efficiency with which this system utilizes bandwidth for a particular installation. Following parameters are available: • A common definition of spectral efficiency with respect to modulation or modulation efficiency in Erlangs/Mhz/Km2, is ? m = (Total traffic carried by the system) / (Bandwidth) (Total coverage area) • Total coverage area = 4000 Km2 • Average holding time of a call = 100 s • Average number of calls per unit during the busy hour = 1.2 • Call blocking probability = 2% • Cell area = 8 Km2 • Frequency reuse factor = 7 Questions : i) Calculate the number of calls/hour/cell and the number of calls/hours/km2 ii) Calculate the number of users/hour/cell and the number of users/hours/channel iii) Find the modulation frequency for this system.
