IWRL6432: Parameter issues with chips

Hello,

1. What is the maximum supported angle for radar FOV?

FOV depends entirely on the antenna design. For information about the maximum supported FOV for each of the antennas that we have designed for our evaluation boards as well as for our partner's modules you can refer to the antenna pages in the Radar Toolbox.

2. How many kinds of gesture functions can algorithms support?

If you are referring to our hand gesture recognition examples and wondering about the number of distinct hand gestures that are supported, I can say that the example for IWR6843 supports 9 gestures and the example for IWRL6432 supports 6 gestures but the number of gestures is really only limited due to the accuracy of gesture recognition. Since we are using machine learning for these examples then if more gestures are added there will likely be less accuracy if using the same model structure etc... It may be possible to have a greater number of gestures and maintain the accuracy level if the structure of the machine learning model is altered but eventually the model may become too large to run on the device due to memory constraints.

3. Is there low power consumption?

The "L" family of devices (ex: IWRL6432) are designed with a specific power architecture to be useful for applications requiring low power consumption. The older gen devices (ex: IWR6843) consume much more power but we do have example software which implements "low power modes" and other software optimizations which reduce the power consumption that you would see in the out-of-box demo.

4. Can antenna design be supported?

Can you clarify what you mean by this? There are several third party companies which will assist in the antenna design process. We can help direct you to those companies if needed. We also provide publicly all of the design files for the antennas on our evms for your reference. 

Best Regards,

IWR6843 is much higher. What is its specific power consumption?

The specific power consumption varies greatly depending on the radar configuration (number of antennas enabled, chirping duty cycle, processing time, etc..) but for IWR6843 the average power consumption can range from 0.5-2 W whereas for IWRL6432 it will be more in the range of 3-100 mW. 

By Out-of-Box demo, I am referring to the base demo software that comes as part of the mmWave SDK. This is typically what all of the other example code for specific applications is built off. We have a modified version of the out-of-box demo which has software optimizations which reduce the average power consumption (such as, clock gating of certain subsystems when they are not in use, etc...). Here is a link to the user guide for that example. The modifications made are discussed at a high level in this application note including expected/measured power savings.
