account before setting the RSSI threshold. Generally, the following four site
configurations are available for your reference.
2.7.2.1 Overlapping coverage
This scheme is designed for a large city or an area where a large population is
present. It involves a number of sites and much overlapping coverage. In the
overlapped areas, multiple frequencies are used, while the non-overlapped areas
share frequencies, but different color codes are required for roaming service. In
some cases, a user may be within coverage of three to four sites at the same time,
and it takes about 10 minutes to move from one site to another.

2.7.2.2 Non-overlapping coverage
This scheme is designed for the countryside or a single part of a small city. It
involves multiple separate sites and no overlapping coverage is present. The
non-overlapped areas share frequencies, but different color codes are required for
roaming service. With this scheme, a user may be within coverage of one site at the
same time, and it takes several hours to move from one site to another.
