Selling and Using of cordless phone become illegal, For what???
may be because of some frequency related issues.
A lot many of them are actually another type of wireless radio hand set, and you can get ones up to a range of 30 KM, can use them in terrorist activity without getting caught. It would be stupid if there is any other reason as still the ones operating at home operate in the range of a wifi band, ban the wifi too after this I suppose, if there is no logic
