    Data Loss
In summary: I suggest you look into it more. Thanks for asking!In summary, a transceiver with a data rate of 1.2kbps will lose more data during transmit than a transceiver with a data rate of 19kbps. If there is some noise which causes a loss of connection, then for a given time the faster link will lose more data. However, neither transceiver will lose any data if the transmission path is loss free.

Hi! Recently I done some survey on transceiver, may I know if a transceiver which data rate is 1.2kbps and a transceiver with data rate 19kbps, which transceiver will loss more data during transmit?
Can anyone recommend me a suitable transceiver?(data rate high, loss of data low)
thanks!

The loss rate shouldn't depend on the data rate
If there is some noise which causes a loss of connection then for a given time the faster link will lose more data, ie. if the interference lasts for 0.1sec then one link will lose 120bits while the other will lose 1900bits.
On the other hand if you need to transmit a certain amount of data then the faster link will allow you to send it more often or to send more error correction bits.

Neither will lose any data if the transmission path is loss free.

Handshaking is usually included and this keeps checking to see if the transmission was received OK. This is done with checksums.

If there are losses, the transmission is sent again. Doing this slows the process down, but unless conditions are very bad, the faster system should still work out faster than the slow one, especially if the faster one is 16 times as fast as the slow one as in your example.

Can't suggest any transceivers as you haven't explained what you want to do. Probably couldn't anyway.

thanks a lot! What I want to do is to transmit data from sensors such as pressure,temperature by wireless transceiver to my computer, and the distance between my computer and those sensors more than 300m.

It matters how much of the project you can do yourself.
If you are not too familiar with electronics and sensor interfacing, A to D converters and computer programming, you may have to look for a commercial data logger module.

If you have experience with these things, there are 433.92 MHz transmit / receive modules which are quite legal in some countries and are available cheaply. These could provide the data radio link.

Please have a look at these files as well as the main site :

Actually collecting the data would be easy with a Picaxe chip.
I suggest you Google this. These cpu chips that have precision A to D converter inputs and Ascii outputs. Ideal for your job.

Here is some more info about Picaxe chips :

This is fun stuff to do.

1. What is "loss of data during transmit"?

Loss of data during transmit refers to the situation where data is not successfully transferred from one device to another during the transmission process. This can occur due to various factors such as network errors, hardware malfunctions, or software bugs.

2. How does loss of data during transmit affect my work as a scientist?

Loss of data during transmit can have significant consequences for a scientist's work. It can lead to inaccurate or incomplete results, wasted time and resources, and delays in research progress. Therefore, it is crucial to prevent or minimize data loss during transmission.

3. What are some common causes of data loss during transmit?

Some common causes of data loss during transmit include network congestion, faulty network equipment, power outages, corrupted data packets, and software conflicts. It can also occur due to human error, such as accidentally deleting or overwriting data.

4. How can I prevent or minimize data loss during transmit?

To prevent or minimize data loss during transmit, you can take several precautions, such as using reliable network connections, regularly backing up your data, and implementing data encryption. It is also essential to test your network and equipment regularly and have a contingency plan in case of data loss.

5. What should I do if I experience data loss during transmit?

If you experience data loss during transmit, the first step is to identify the cause of the problem. You can troubleshoot the network or equipment, check for software updates, or contact your IT department for assistance. If the data loss is significant, it may be necessary to retrieve data from backups or consult with a data recovery specialist.
