Darrin Wright Due: November 6, 2011 ITT 650 P.8.1. What are the specific advantages of static channel allocation over dynamic channel allocation channel strategies? A static allocation has a fixed number of channels allocated to each cell while dynamic allocation implies that allocation of channels. P.8.4. If you do not sector cells, can you still borrow channels from adjacent cells? Explain clearly. Yes. If you do not sector cells, the channels can still be borrowed and used with the “ x” cells, but they would cause interference with the “abc” cells of the clusters. P.8.13. How do you compare hybrid with flexible channel allocation? Which one would you prefer and why? The HCA is has traffic channels with traffic channels divided into fixed and dynamic sets.

Unformatted text preview: The FCA is similar to HCA but its channels are divided in to fixed and flexible sets. I prefer the FCA because the flexible channels are only used by the cells only when more channels are needed after utilizing the fixed set. P.8.16. A service provider decided to split each hexagonal cell of 20 km radius to seven microcells of appropriate size. (a) What is the size of each microcell? 20km/ 7 = 2.86 km (b) How is the signal strength influenced by such a redesign? The signal strength isnt as strong (c) What is the CCIR compared to the original design, assuming the propagation path loss slope = 4.5 It could cause deterioration, which leads to finding new channels....
