Figure 3-5: Coverage Service Area with Cell Overlap
The combination of Cell Overlap and Dynamic Channel Allocation increases the
flexibility and the capacity of the system. Every user has access to all channels
(77x4) due to the overlapping base station topology. Cell Overlap enhances the
reliability and service quality. One malfunctioning base station does not affect
the performance of the system. Due to the Dynamic Channel Allocation, there is
no need for frequency planning, which allows the network to meet operators
current demands with the option to easily expand at a later date.
3.1.3 Air Interface Handling
The radio interface has four-channel time division multiple access capability with time
division duplexing (4-channel TDMA-TDD), which provides one control channel and
three traffic channels for each cell station.
