Interesting reasoning here: "the reasonableness of a cordless telephone user's expectation of privacy depends on the specific technology involved."
Considering that analog cell phones and cordless phones use the very same modulation method (FM), albeit at higher power for the cell phones (making them much easier to intercept than cordless phones at a distance), it would be much more accurate to say "...depends on whether the specific technology involved has a large US industrial base lobbying for it". Cellular is protected under ECPA because it's big bucks for some powerful US businesses. Cordless phones don't use a large domestic infrastructure that charges for airtime. The only money in cordless phones are in the phones themselves, which are invariably made overseas. And Japanese, Chinese and Korean businessmen can't vote in US elections. Phil
