UWB to connect several devices in parallel while sharing the same RF channel?

Wireless Connectivity Ultra-Wideband

Hello,

I’m searching for a way to link several devices simultaneously using a fixed UWB RF channel for UWB data connection.
I was employed by Bluetooth, which operates between 2.4 and 2.48GHz (80MHz to 40 channels, each 2MHz) and allows for the interference-free connection of many devices every 2MHz.

Is there any alternative concept in DW1000 similar to BLE? I discovered a sub-banding technique online. Can I use Sub-Banding with DW1000 or DW3000 modules?

Thanks in advance

He Velli,

In order to share the air across multiple UWB devices and use the same RF channel, you will have to implement a TDMA scheme so each devices are synchronised and receiving/transmitting in dedicated slots.

If you use the QM33 SDK 1.0, Qorvo is delivering some application implementating FiRa TWR with contains is a TDMA application. You can also build your custom application on top of the driver API (recommended for advanced users)
