My bad. Rounded to 2 significant digits:
Class 1 is 100 m (~330 ft).
Class 2 is 10 m (33 ft).

Interesting!
Well I have an Anycom USB250 which is their re-branded BCM2045 that I
use for VOIP and it does way less than 400Ft/120M/Class 1 it's spec'd
for in practice could be my Motorola HT820 headset nevermind wifi
interference.
Had not realized there were 300M Class 1 transceivers out, what
chipset does it take to get that? Sure would like to replace my dongle
if it meant I could get more than 30Ft in the house. ;)

I'm interested in the Bluetooth v2.1 spec (higher data rates and less
power dissipation) and Class 1 (300m) range. I'm looking for
low-power, high data rate wireless data technologies with enough
range that they be battery powered for days or weeks at a stretch.
They would be riding up and down on the bell part of a 600 liter bell
prover (a primary gas flow standard).
The Belkin F8T016 (same specs, but Class 2, 10m range) might work in
a pinch, but the short range could be a show-stopper.
Maybe Rocketfish dongle would work as well (Class 2), but never heard
of them.
Broadcom BCM2046 is a Bluetooth 2.1 +EDR Class1 HCI chip in 130nm. I
also saw BCM2070 (65nm) on Broadcom's product list which may be
bumping the BCM2046 - who knows?

As usual Belkin is less than detailed with the spec sheet! Can't
tell if it's Broadcomm's 2046 or what so I'd be suspect over other
dongles.
What's drawing you to them?
