A system, method and network device for covering a plurality of areas by one cell are disclosed. The system comprises: a plurality of radio frequency groups and at least one base band unit. One radio frequency group corresponds to one area of the cell, one radio frequency group corresponds to one date channel, and one base band unit is connected to a plurality of radio frequency groups through a plurality of date channels. The embodiment of the invention reduces the signal interference among each area of the same cell, increases the system capacity, and benefits cell splitting, i.e. benefits increasing the capacity and upgrading during network enhancement. |
