well, this is a good question, if you are planning to use a "pair" of this 
devices one as master and one as a slave with some external omni atennas that 
you might get maybe 80m or so but only in LINE OF SHIGHT!!!, in normal shack 
conditions with wires and shields I would say maybe 10m or so. Also important 
the level of interference in ISM band, the modulation for BT devices is GFSK, 
DQPSK and DPSK, the good part is the BT protocol is designed to avoid 802.11 
b/g/n/ac and can go up to 2485Mhz and at least for NA the upper freq is ch 11- 
2462  as central freq so at 30dBc you'll get 2473, so there is some free 
sectrum room to avoid house interference from wifi equipement (in EU I think 
can go up to ch 14). The BT  BW is 3Mhz as far as I remember plus the protocol 
is close to FHSS one. However the biggest BT killer are the 2.4Ghz wireless 
phones, try to avoid this at home (I witched with DECT ones). Having a free of 
interference spectrum will
 "extend" the coverage coz the RSSI on wifi devices is not an absolute value 
(is a long story with wifi/BT rx calibration) and is enterily based on SNR, if 
there is an interference the BT device will "report" a lower RSSI and will 
decrease the modulation scheme. In my HF shack I had no problems with HF 
interference (no wonder the spectrum is faar away) consider mounting this 
gizmos with external antenna in a pair config and do not relay on internal 
computer BT card....my two cents

Hi Daniel
That's an interesting solution too and cheaper than the WiFi units.
Do you know what would be the range using a Lenovo notebook (the adaptor should 
be OK for 100m according to the spec., but I don't know about the notebook)?

I was thinking at this one
http://www.ebay.ca/itm/221236298021?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649#ht_2256wt_701
 
there are cheaper solutions on ebay but I am not sure if can handle RTS and CTS.

Hi,,

Works great for what? That's an Ethernet to Wi-Fi adapter. What's needed is
an RS232 to WiFi adapter.
