I.3 The evaluation and planning of the U900 base stations

Use case
Name The evaluation and planning of the U900 base stations

Description The U2100 base stations are 3G base stations deployed in the 2100MHz band and
the U900 are base stations deployed in the 900MHz band. The 900 can provide
superior coverage compared to U2100. To evaluate the effect of the U900 in the
real scenes, the MR data before and after the deployment of the U900 base
stations in one particular area are collected. Figure I.1 shows the received signal
code power (RSCP) before and after the deployment of the U900 base stations. In
this figure, the coverage levels are distinguished by different colours. We can see
that through the deployment of the U900 base stations, the coverage of the mobile
network has apparently been improved. In the future construction of the mobile
network, the U900 can be used to improve the coverage.
