WiFi/Bluetooth Coexistence Testing

[rvargo]

Hi, I am working on a product that has both Bluetooth and WiFi. It has one antenna for Bluetooth, and a separate one for WiFi.

I want to measure how much isolation I have between the 2 antennas, to make sure they can coexist. I also want to compare different antenna architectures. Most coexistence testing I've read about looks at throughput or something similar.

I'm hoping to see how many dB of isolation I get between antennas. Is there a standard way of doing this? I was thinking something as simple as using an RF signal generator to put a signal on one antenna, then measuring the signal on the second antenna.

Is there a better, more standardized way of doing this?

Thanks.

You can use some duplexer/filter/circulator at one antenna to test another antenna. Make sure both two signals transmiting, because this status is different from only exciting one antenna.
