An SHDSL modem is a transmission device that enables high-speed and stable data transmission over long distances using telephone lines.
Compared to methods such as UTP and optical wiring, the installation of optical fiber cables that extend several kilometers generally requires huge costs.
An SHDSL modem, on the other hand, is relatively simple and requires only a short construction period, resulting in a low-cost long-distance transmission network.
This make SHDSL modems very suitable for use in large areas such as factories, airports, and railroads, because they can be installed at a very low cost.
By using existing telephone lines, LANs can be extended to locations several kilometers away.
This is ideal for facilities with large areas, such as factories, parking lots, campuses, shopping malls, ski resorts, airports, and train stations, where LAN wiring and fiber optic installation would be very expensive, but SHDSL enables creation of a low-cost network by using pre-existing lines (SHDSL requires an open copper line), it is possible to extend the network and LAN at low cost.
Thus, it can be said to be a cost-effective solution since existing facilities can be used as they are.
SHDSL modems have the following characteristics.
First, the installation cost is much lower than other methods such as optical fiber.
This is because existing premises telephone lines are used, so there is no need for any new wiring work.
Compared to other methods that require wiring work and other construction costs, installation costs are lower.
Second, installation itself is overwhelmingly simple.
All that is required is to install SHDSL modems at both ends of an existing telephone line.
It is also possible to use copper lines.
And while installation is this simple, long-distance communication is also possible.
With Ethernet, the maximum distance is 100 meters, but with SHDSL and VDSL, LANs can be extended to several kilometers away.
In addition, high-speed communication is also possible.
Furthermore, the symmetrical design allows bi-directional communication at the same speed.
If a VDSL modem is used, even faster communication speeds of up to 100 Mbps in both directions are possible.
Finally, speeds can be increased by using additional bonding technology.
Bonding is a technology that bundles multiple lines together, and by bundling lines together, speeds can be improved.
