Part Number: IWR6843AOP
According to the document in the link below, the detection range of mmWave sensor is 100+ meters.
For people counting and tracking applications, a customer would like to confirm if the mmWave sensor can count people in a 100 x 100m outdoor location.
Please see the User's guide for the Long Range People Detection Demo: http://dev.ti.com/tirex/explore/node?node=AHoEHc6j2uX.XSbB65w0Tg__VLyFKFf__LATEST, check the Performance expectation section. When using a 100 meter chirp configuration, we are limited to a 90 degree FOV. A single device will cover a 90 degree cone of length 100 meters.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Justin Curewitz:
Thank you for sharing the link to the Long Range People Detection Demo. For people counting applications, what would be the possible limitations in the number of people it can measure in a 90 degree cone of 100 meters length? Is it the limitation of the software or the mmWave itself?
In reply to Danilo Austria:
We primarily test this demo for speed of detecting people and ability to avoid false detections. The software is limited to 20 tracks, so if 20 people are detected, you will not detect the 21st person to enter the scene. This limitation is based on available memory to store tracking information for each tracker person.
Thank you for your response. The customer have further inquiries as follows.
A) If we were to buy this instrument, we would need to buy the IWR6843ISK and the MMWAVEICBOOST , right?B) Our intent is not only to use this outdoors but also indoors. If we were then to implement this in a small room, would the IWR6843ISK suffice alone? Or would we need another device?C) In both cases, we would also need:
1) Something to place the instrument (for example, a tripod and a smartphone clamp)2) A power supply (5V, 3A) to power up the instrument3) A computer and a micro-USB cable to process the data.Is this right?
D) Will the instruments be "naked"? By this I mean, will we need to provide something to protect them from dust/rain/wind/etc. ? Or do they have some sort of protective case? If not, do you sell one?
A: The latest EVMs are standalone, and don't require an ICBOOST. However, if you use Long Range People Detection and intend to use the 100 meter configuration, you need to ICBOOST to provide enough power to the IWR6843 device to support beamforming. My recommendation is to purchase the ICBOOST if you are going to do any type of outdoor detection, incase the 100 meter detection scenario interests the customer. If you are only doing indoor testing, you can get by with just the ISK EVM, but if you want GPIO access you will need the ICBOOST.
B: IWR6843ISK can work very well indoors using the "Sense and Direct: HVAC Control" demo when wall mounted. If you want to mount on the ceiling, I suggest purchasing the IWR6843ISKODS EVM.
C: You need
D: These EVMs don't come with any type of case. We do not sell one. Some plastic cases can cause signal degradation, try to conform to the guidelines in section 5 of this document.
