I agree with you 100%. If you have sensitive data then yet it should either be going over a wired connection or a secure tunnel/vpn when going over a wireless connection.
My point was that adjusting the TX power does serve a purpose though. In many situtation were you want to try to prevent your signal from being broadcast farther than the needed. Not even for any security reasons but to try to prevent APs from causing noise onto each others channel.

Unsafe. Howver generally people on it are uninterested in the data passing across it just because of sheer volume. If you have data that is sensitive or you just don't want people to view it use tunneling, that's what Ipsec and PPTP were invented for. i.e. leave your APs open and tunnel into your "own" network. My view is that lowering tx and using directional antennas is a courtesy thing. If you spend time thinking about your design you get better performance because you have less noise.

But for typical laptop w/ integrated wireless reducing the power would help reduce the range. You deal with the 99% and try your best to protect yourself from the 1%.

If the receiving end uses a high performance antenna they can both talk and listen to your AP many miles away. 2. High power cards only gives you more noise. Stick to a cm-9 type card with high RX sensitivity. That will give you much better results. You can not restrict the range of wireless buy lowering the output RX power. Radio lan can not be restricted this way. It's a 2way communication, so anyone with a high gain antenna can both talk and listen to a low powered AP. Range for a 100mw card with a 32dbi directional antenna at NLOS is about 120KM so if you guys think that restricting the TX power is going to keep you safe from the next door internet café, then you are very much mistaken.
