IWR6843: Comparing to 24G products

Tom Fisher

Part Number: IWR6843

Hi,

We've found there are several 24G radar solutions based on Infineon's products and our client needs a list comparing 24G solutions with ours that are based on 60G. Would you please help us to elaborate some key points that we can persuade our client not to choose competitors' solutions based on Infineon's 24G or 60G products?

What we could propose are:

1. their existing solutions lack the ability of better angle information since their devices have less than 2 receive antennas

2. their range resolution is worse than ours since the available bandwidth is 2G

But the price of their devices is unbelievable and just $3.xx for 1K. 

It would be really appreciated that if you guys could point out some intrinsic flaws about its center frequency or their design philosophy. This is urgent and a headache problem that everyone using TI's solution will have to face when going to the market.

Thanks

Tom

    Hello

    It would help to know what exact features are looked at to do a fair comparison.  As you may be aware Ti's mmWave devices provide on chip capability for post processing of RF signals and decision making, This enables numerous standalone applications and ease of design.

    It may further help to narrow down what kind of applications you are trying to use TI's mmWave sensors in.

    From  BW and frequency perspective you may want to look at the following white papers :

    Moving from legacy 24GHz to state-of-the-art 77GHz radar

    Leveraging the 60-GHz RF band to enable accurate mmWave sensing

    Please see the following to see advantages of Ti's mmWave family :

    mmWave radar: Enabling greater intelligent autonomy at the edge

     How antenna-on-package design simplifies mmWave sensing in buildings and factori (Rev. A)  Simplifies RF designs complexity and size.

    Hope this helps you extract the relevant pieces for comparison.

    Thank you,

    Hi Vaibhav,

    Thanks for your great answer which helps a lot.

    We are competing a large  project for smart home in which appliances  in every  room are controlled by a radar via BLE or WiFi. For the bedding room, vital signs and sleep monitoring are supported. In addition,  intrusion detection is also supported for the whole environment.

    Our competitor utilizes a bunch of the low price 24G sensors to complete with centralized solution, which is still much cheaper than ours per room.

    All of our product lines are basically  human activities related  applications and we’ve been seeing many Infineon  solutions in these days. Their prices  are unbelievably  competitive for simple cases and still competitive for complicated cases.

    Would  you and your team please give more suggestions about this scenario from the tech perspective or  any other perspective?

    Cheers,

    Tom

    Hello

    Single sensor that fits multiple applications and scalable portfolio for easy portability across various device platforms should help for building an ecosystem of sensors with varying features  with common platform.

    This is where one time development  can be reused across the wide range of  60Ghz devices and antenna configurations.

    Application specific information may help in further determining how the portfolio helps.

    Thank you,

    Vaibhav
