Types of Interference in Mobile Communication
- Co-Channel Interference
- Adjacent Cell Interference
Co-Channel and Adjacent Channel Interference in Mobile Computing
Co-channel interference is not actually an interference but more a sort of congestion when more than one device is operating on the same frequency channel. It hinders performance by increasing the wait time as the same channel is used by different devices. Sources of interference are as follows:
- Another mobile in the same cell.
- Ongoing call in neighbor’s cell
- When a different Base Station operates on the same frequency.
Types of channels on which interference is present are-
- On Voice Channel: leads to crosstalk which is an interference or background noise while we are talking to another person on mobile. Crosstalk is unwanted interference that should be minimized.
- On Control Channel: It can lead to problems in creating a connection between the sender and receiver during a call which leads to missed calls. Calls may terminate abruptly known as blocked calls.
Interference causes the above two problems because it reduces the channel capacity and thus, affects the performance.
