Cell Phone Bands—A Question
This raises an obvious question: Why don't all phones have four and three? One possible answer is that additional frequencies are in some way costly, require more expensive hardware or use more power. That does not strike me as very likely, but it isn't a subject I know much about.
A second possible answer is that phones are being deliberately designed to work well in only one area, in order to enable some form of price discrimination.
Do any of my readers know the answer? From the standpoint of this consumer, the consequence of the limitation is that, not uncommonly, the phone I am most interested in is out in a European version but not an American version.
