The term Wi-Fi is a trademark of the Wi-Fi Alliance, formed in 1999 to promote 802.11b. It did not apply to 802.11a until 2002. 5 Ghz support didn't start to become popular until the days of the 'pre-N' routers, which offered an early implementation of MIMO and sometimes dual band. A device marked B or G operates on 2.4Ghz. A device marked A operates on 5.0Ghz. A device marked N is ambiguous. It's odd for a dual band device not to support A and say so. | |

However, both WiFi 802.11a and 802.11n can support 2.4GHz and 5GHz, but this is not available unless both the AP (access point) and client (your device) both support 5GHz. The other advantage for the 5GHz spectrum is that it is not overcrowded and is (generally) unaffected by cordless phones and microwave ovens. | |
