TDMA (Time Division Multiple Access) is a technology used in digital cellular telephone communication that divides each cellular channel into three time slots in order to increase the amount of data that can be carried.

Here's a step-by-step explanation of the channel capacity of TDMA in a cell system:

1. **Channel Division**: In a TDMA cell system, the entire bandwidth is divided into multiple channels. Each channel is further divided into time slots. Each user is assigned a specific time slot for transmission. This means that only one user can transmit at a time on a given channel.

2. **Time Slot Allocation**: The time slots are allocated in a cyclic and sequential manner. Each user is given a unique time slot during which they can transmit or receive data. This time slot comes back after a fixed interval of time, hence creating a cyclic pattern.

3. **Data Transmission**: During the assigned time slot, the user's data is converted into a burst and transmitted. The receiver, knowing the time slot of the sender, listens for this burst and receives the data.

4. **Channel Capacity**: The channel capacity in a TDMA system is determined by the number of time slots per cycle. The more time slots there are, the more users can be accommodated, and hence, the greater the channel capacity. However, increasing the number of time slots can also increase the chances of interference and can decrease the quality of the transmission.

5. **Efficiency**: TDMA is efficient because it allows multiple users to share the same frequency band without interference because they are transmitting in different time slots. This increases the capacity of the network without requiring additional spectrum.

6. **Limitations**: The channel capacity of a TDMA system is limited by the number of time slots that can be effectively managed without causing interference. Also, there is a limit to how much data can be transmitted in each time slot, which also limits the overall capacity.

In conclusion, the channel capacity of a TDMA system in a cell network is determined by the number of time slots and the amount of data that can be transmitted in each slot. It is an efficient way to increase capacity without requiring additional spectrum.
