devolo Giga Bridge
Expansion of the internal home network using
a telephone line
In this scenario, the G.hn signal is transmitted over
two or four telephone lines between the router
and another LAN device with an Ethernet port at a
data rate of up to 1 Gbps. In the case of two tele-
phone lines, SISO mode is used. In MIMO mode, all
four lines are used as two pairs. MIMO mode is rec-
ommended only for large distances exceeding
100 metres. For shorter distances, MIMO transmis-
sion does not provide any higher data rates.
Expansion of the internal home network using
a coaxial line
In this scenario, the G.hn signal is transmitted over
a standard coaxial cable between the router and
another LAN device with an Ethernet port at a data
rate of up to 1 Gbps. Only SISO mode can be used.
Due to the high RF performance of coaxial cables
and the very high amount of insulation, long dis-
tances of several hundred metres can be bridged at
data rates of up to 1 Gbps.
