3G signals attenuate severely when
traveling through building walls, floors, and windows, leaving more than 40% of
homes and offices with poor indoor coverage …
e.g In Singapore IDA addresses this issue
by demanding a Higher Levels of Service from 3G Networks: Indoor
coverage within buildings has to be at least
85% coverage.
Example of Coverage Improvement for a
home with Cel-Fi
