Are there routers available which allow to introduce latency and configure BER for testing

Question

I am currently working on an application which is a client server based application. The client and server will be on a wireless network with limited bandwidth and both could be moving. I need to simulate latency and BER issues in order to test and ensure that my application's performance does not degrade too much.

I was wondering if there are any routers available which will allow me to introduce latency and also increase or reduce the BER. If anyone knows of such a router which I can buy from the market or a software which I can install to simulate this on LAN, please do answer.

Thanks.

You can try netem if your application running in Linux. With it, You can simulate packet delay, loss, corruption .etc
