I have been getting several requests for analysis of devices that use the WirelessUSB standard. This standard uses MB-OFDM in UWB channels. These UWB channels are in the frequencies shown:
As you can see, none of the band groups overlap 2.4GHz. Then I get a request for a devices that claims to use WirelessUSB LR. This device uses DSSS modulation with a 1.5 MHz channel in the 2.4 GHz range.
As you can see here:
I have a few questions:
Have you been getting requests to use these devices in your RF domain?
Have you had as hard a time as I have trying to hammer out the standards just to come across devices that do not follow them?
Have you heard of WirelessUSB LR? Or seen a standard for this?
