11 Introduction
2.2 The solution:
devolo Giga Bridge
The problems mentioned here mean additional ef-
fort and costs, but the Giga Bridge provides a solu-
tion. It uses the G.hn standard to bridge the gap
between the NT/ONT and router or terminal de-
vice by using the home's existing coaxial line (SAT/
TV) or telephone line.
The Giga Bridge can also be used to expand the in-
ternal home network in order to connect devices
with an Ethernet port, e.g. computers, notebooks,
televisions, game consoles, etc., to the Internet.
This also achieves the best performance and stabil-
ity in places where network lines are not possible
or not wanted, and/or where Wi-Fi frequently
drops out due to ceilings and walls.
And the best part is that the Giga Bridge is con-
nected easily by plug and play.
G.hn technology explained
The Giga Bridge uses G.hn technology for the
transmission of the Internet signal over coaxial
(TV/SAT) or telephone lines. G.hn was developed
by the International Telecommunication Union
(ITU) with ongoing development provided primar-
ily by the HomeGrid Forum industry association.

2.3 Possible applications of the
Giga Bridge
Telephone line: Two telephone lines are used
b
here. The speed between the ONT and router
can reach up to 1 Gbps and the range can be
up to 100 metres.
Coaxial line: Coaxial cables have very high
b
amount of insulation and high RF performance
(radio frequency). The speed between the ONT
and router can reach up to 1 Gbps and the
range can be several hundreds of metres.
SISO mode is set to 200 MHz.

2.3.1 Expansion of the Ethernet WAN

Connection using a telephone line
In this scenario, the G.hn signal is transmitted over
two or four telephone lines between the ONT and
router at a data rate of up to 1 Gbps. In the case of
two telephone lines, SISO mode is used.
