Ol/ul community

Ol/ul cells, also called concentric circles, are generated to reduce the frequency reuse distance, reduce frequency interference, and expand network capacity when the traffic volume increases constantly and frequency resources are limited.

The ol Community undertakes the traffic near the base station. The traffic volume is high and requires a small amount of transmit power. The Inter-cell interference is small and the frequency of reuse is more closely. This mainly solves the traffic.

Ul Community undertakes the traffic of the outer layer, with a small traffic volume, requiring a large amount of transmit power, high mutual interference between cells, and sparse reuse of frequency points, mainly solving the coverage problem.

Ol cells: Use Frequency Points with severe frequency interference; Ul cells use relatively clean frequency points;

Rldei: Cell = 201790471, c0000ype = GSM;
C0000ype: the type of the cell system. Possible values: DCS1800, GSM, and pcs1900.
