If you have a bad radio link, this can lead to brief transmission impairment due to bad signal quality or even interference. It is possible that the TIM modules recognize a connection break and then re-establish the connection shortly afterwards. In such cases, bookkeeping messages are always sent before data messages can be exchanged again.
These brief interferences, which usually last only seconds, finally lead to the overall radio transmission becoming very sluggish and even unstable, because too many bookkeeping messages have to be exchanged.
Take the following measures to minimize recognition of connection and ensuing exchanging of bookkeeping messages.
- In the case of a bad radio link you can set interference suppression on the dedicated line of the TIM 4R-IE. If brief interferences occur, no bookkeeping messages are exchanged between the central TIM 4R-IE and the communication partner.
- Increase the repeat factor
- Increase the extra transmission time
- Use long acknowledgment
The long acknowledgment prevents data loss with radio links, because interference or noise on the radio link might be erroneously mistaken for a short acknowledgment.
