Hi

Basically, it is simply a WLAN hotspot.
Advantages over Eifon:
- Better reception
- Eifon does not break down because of heating up during longer use
- More stable W-LAN signal
- Larger range of the W-LAN signal
- Massively cheaper than an Eifon
- Possibility to connect it as a general router in the network via RJ45
- Not sure but: Possible to connect to the internet via USB interface with the PC
- More bandwidth in the W-LAN possible
- and much more.
