Skype Mars One h1 supports dual-band wifi.

Dual-band Wifi means that the device simultaneously supports 2.4GHz/5GHz dual-band wireless signals, which can support a complete wireless network including 802.11a/b/g/n, and belongs to the fifth-generation Wi-Fi transmission technology (5G Wi-Fi), which is supported by routers or some Wifi devices in daily contact. Wifi devices support 2.4Ghz Wifi, as long as some high-end routers or the future of some tablets, boxes and smartphones may be able to use this newer generation of wireless technology.

The advantage of dual-band Wifi devices is that they have stronger and more stable Wifi signals, higher transmission speeds, and allow for more power-efficient wireless devices to meet the future needs of high-definition and big data wireless transmission.
