The transmission data rate is decided by several factors:

1. Bandwidth: The range of frequencies that a communication channel can carry. A higher bandwidth allows more data to be transmitted in a given amount of time.

2. Signal-to-Noise Ratio (SNR): This is the power ratio between the signal (meaningful information) and the background noise (unwanted signal). Higher SNR means that signal quality is better, and thus higher data rate can be achieved.

3. Error Rate: The number of errors that occur in a communication system. If the error rate is high, the data rate will be low because more bandwidth is used to send error correction codes.

4. Modulation Technique: The way in which the data is encoded onto a carrier signal. Different modulation techniques can provide different data rates.

5. Channel Coding: The coding scheme used can also affect the data rate. Some codes can detect and correct errors, allowing a higher data rate.

6. Path Loss: The reduction in power density (attenuation) of an electromagnetic wave as it propagates through space. Path loss is a major factor in setting the maximum possible data rate.

7. Multipath propagation: This occurs when signals reach the receiver by two or more paths. It can cause interference and reduce the data rate.

8. Network Traffic: The amount of data moving across a network at a given point of time. If the network is congested with high traffic, the data rate can be affected.
