Ever since mobile phones became "smart", some manufacturers seem to have lost sight of the fact that a mobile phone's primary function is just that - a phone. Consequently, attention to good RF design is of paramount importance. Manufacturers do not appear to publish a mobile phone's radio frequency (RF) sensitivity. This is measured in units known as dBm. As such, it is difficult to compare one phone with another.
With specific reference to the HTC Desire S, I own one such device. I find it amazing that HTC chose to put the phone's antenna into a part of the phone shielded when the phone is held normally. What say we reintroduce the good old-fashioned external antenna? Were they really an eyesore?
