As seen in Table 1, the FCC limits equivalent isotropically
radiated power (EIRP) to -41.3dBm in the 3.1GHz - 10.6GHz
range, with even tighter restrictions in other frequency ranges.

Frequency (MHz) EIRP (dBm)
960-1610 -75.3
1610-1990 -53.3
1990-3100 -51.3

Above 10600 -51.3
UWB Consortiums and Alliances
Interoperability is critical to ensure mass adoption of UWB.
Because every user expects their electronic devices to easily
connect and operate with minimal or no effort, it's vital that
products, systems, applications, and services from different
vendors work together reliably and predictably. Different players
within the UWB industry—from semiconductor suppliers to

device manufacturers and test equipment vendors—have
already started to address this need for interoperability.
Notably, several key consortiums and alliances are
collaborating to ensure the interoperability of UWB products.
Among their goals is to create protocols that ensure your car
can talk to your phone, your phone can talk to your door lock,
and your phone can communicate with location infrastructure.
