Is it normal that 5ghz has less signal strength? It works fine on my wife's laptop, hasn't dropped once on there. Perhaps iCrap was just in an iMood. Seems to switch to 5ghz fine now. |
2.4GHz has a longer wavelength due to the lower frequency which allows the signal to travel futher and through objects easier. 5GHz on the other hand is more susceptabl to attenuation and and does not travel as far. So, 2.4GHz will travel futher than 5GHz.
Having said that, there are many more sources of interference on 2.4GHz as opposed to 5GHz which is relevavely clean in comparison. So, if you can get an Access Point(s) that can service your needs in terms of signal strength on 5GHz, it will usually perform better than 2.4GHz. It's also worth noting that newer modulation techniques and performance 'enablers' such as 80-160MHz channels, Explicit Transmit Beamforming, 256QAM etc. only work in 5GHz (802.11ac is 5GHz only).
As for your laptop vs. iPhone, the laptop will have a more powerful Wi-Fi adapater. That extra output power can acheieve greater distances (and possibly performance) than your phone. Apple devices actually tend to have fairly decent chipsets. It's simply a matter of your Access Point being too far away from your phone (the laptop is able to compensate).
