Site Selection(General Considerations‚Äč)

Proper site location determines usefulness of its cells

Sites are expensive

Sites are long-term investments

Site acquisition is a slow process

Hundreds of sites needed per network

Bad Site Location

Avoid hill-top locations for BS sites

•uncontrolled interferences

•interleaved coverage

•awkward HO behaviours

but: good location for microwave links

Good Site Location

Prefer sites off the hill-tops

•use hills to separate cells

•contiguous coverage area

•needs only low antenna heights if sites are slightly elevated above valley bottom.
