OnAccess G42xx-C is based on the latest technology for in-house networking - G.hn Wave 2, which can use any type of coax cable, including the standard RG-6 and RG-59 lines.
The data transfer always takes place in the SISO procedure (2-200 MHz). The frequency range starting at approx. 240 MHz can be used for the provision of cable services. It is therefore possible to transmit both data and SAT TV channels (950-2250 MHz) via a coax cable.
In buildings, coax cables are often looped through from one TV/multimedia outlet to another. This feature is taken into account by G.hn technology - the master device (headend or modem as master) can communicate with up to 16 clients on one cable harness.
The OnAccess G42xx-C series consists of two G.hn headends and several G.hn modems:
In the simplest case - if you want to establish a network connection between two points of a coax cable - two identical G.hn modems are sufficient. One of them takes over the role of the master, the other one - the role of the client.
If you want to build a network over several coax cables, it is recommended to use a G.hn Headends (alternative name GAM = G.hn Access Multiplexer).
It always acts as a master and allows the connection of 6 coax lines (G4200C) with up to 16 G.hn modems per cable.
For even larger networks several headends can be interconnected.
The G4224 headend, which is also available, has a special feature - it can supply its clients (G4202TCP) with power via the G.hn line simultaneously - up to 600 meters away!
Each G4202TCP client can in turn provide power to other devices (e.g. IP cameras) via its two Ethernet ports (PoE+ with 15W/30W up to 100 meters).
