Could someone please tell me the differences between DWM3001C and DWM1001C and why I would want to use DWM3001C? What are the advantages of each?
I’m planning to create a RTLS for a large area (400 m x 4 m) and aim for localization accuracy of < 20 cm.
The main reason to move to DW3000 based design is CH9 support and lower power.
You may well be able to use the DWM1001C and PANS RTLS for your system
The DWM3001C and DWM1001C are both modules used for implementing real-time location systems (RTLS). They are designed to provide precise location information for applications such as asset tracking, indoor navigation, and location-based services.
The DWM3001C is a newer module that is part of the DecaWave ScenSor family of products. It is based on the IEEE 802.15.4-2011 standard and uses ultra-wideband (UWB) technology to provide highly accurate ranging and location information. The DWM3001C is capable of providing location accuracy of up to 10 cm, making it suitable for applications that require high precision.
The DWM1001C is an older module that is also based on the IEEE 802.15.4 standard, but uses a different type of ranging technology called time-of-flight (ToF). The DWM1001C is capable of providing location accuracy of up to 50 cm, which is still very good, but may not be sufficient for some applications that require higher precision.
In general, the DWM3001C would be a better choice for applications that require the highest level of accuracy, such as asset tracking or indoor navigation in complex environments. It may also be a good choice for applications that require a long range, as the DWM3001C has a maximum range of up to 500 meters.
On the other hand, the DWM1001C may be a good choice for applications that do not require the highest level of accuracy and where cost is a major consideration. It may also be a good choice for applications that do not require a long range, as the DWM1001C has a maximum range of up to 100 meters.
I hope this information helps. Let me know if you have any other questions.
your information’s are not so correct.
DWM1001 can support accuracy up to 10cm (PANS firmware can do that if all is well positioned and LOS ). It is all about the installation accuracy, antennas, LOS and other stuff.
The maximum range is more like theoretical issue - I don’t think that with the antennas onboard they can go up to 100/500m meters. For example from our test the DWM1001 and DWM3001 can archive more or less the same range on channel 5 with the same frame format / RF setting.
The DWM3001 is successor of DWM1001 - the main differences are:
- DWM3001 support only channel 5 and 9
- DWM3001 has a much lower current consumption
- DWM3001 support encryption
- DWM3001 support FIRA
There are more differences between DW1000 and DW3000 chip, check it with the Datasheet.
If you are newbie then I would recommend you to begin with DWM1001 as there are far more examples for it than for DWM3001. But the DWM3001 is future.
Thank you for all the information!
Thank you for the information.
