I don't know if there is more than a 'general' answer to the question.
The general answer is higher frequencies have less range for the same power, all else being equal. However, there are other considerations, such as the antenna configuration on the different bands, interference, which is usually lower at 5 GHz and more. Bottom line, there is no absolute answer, but given he was looking at a 5 M distance, either band should work fine. It's also difficult for a user to tell how much power is used, as WiFi uses only a tiny fraction of what the computer would. Cell phones, with a hot spot, would also use more power for the cell network than WiFi. On cell networks, there is a mechanism where transmit power level is adjusted to optimize reception, but there isn't a similar mechanism for WiFi. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
