Problem:
(a) Cellular systems are based on two types of multiplexing, what are those two types of multiplexing? Describe how they are used to improve channel allocation in cellular systems and illustrate your answer.
(b) What do you mean by the HO_Margin and how does it optimise handovers in networks?
(c) Explain and illustrate the different possible handover scenarios in a GSM network.
(d) Explain what is known as Macro-diversity in a UMTS context and how this property inherently caters for such phenomena as multi-path propagation and cell breathing.
