Ultra-wideband is basically wideband plus 1.8 kbps. Wideband ranges from
about 4 kbps to 42 kbps. The useful bit-rates are about 10-28 kbps (add
1.8 kbps for ultra-wideband). Note that ultra-wideband sometimes
produces high-frequency artifacts that make it worse than wideband. It
depends on the application. Test first.
