What is the telephone line network?
The telephone line for the telephone line connects the household computers using existing telephone lines. The standard for this technology is set by Home Phone Networking Alliance, often referred to as Homepna. The first HPNA incarnation, version 1.0, was very slow at 1 megabit per second (MBSP). Version 2.0, developed by Broadcom, increased this speed to a more acceptable 10 Mbps.
The telephone line network uses more channels to transmit data transmission multiplexing (FDM). These channels work on the frequencies of unused voice carrier signals or DSL modems, allowing one telephone line to support all three technologies simultaneously.
The advantage of the telephone line network is that it is easy to install, cheap and reliable. It provides 10 Mbps data speech, regardless of the use of the phone. No other devices such as routers or switches are needed, and the telephone line will support up to 25 devices. Is fast enough toTo add video and work on both Macintosh and PC computers.
Some disadvantages are that the telephone line requires a telephone connector near each computer or the use of extension wires. If a large amount of data is usually transferred between computers, faster technology such as Ethernet (100 Mbps) may be required. The telephone line network also has a physical limit of 1,000 feet (305 meters) of total connection and a cover limit of 10,000 square feet (929 square meters). In some cases, the installation of the telephone network may cause noise on the voice line. Low passage filters can be required in most electronic stores.
If you want to set the telephone line network, an internal PCI card or an external USB card must be installed on each computer. When purchasing cards for telephone network network, be sure to get cards that arerated for HPNA 2.0 or better. The sets come with one or more Asoftware cards. The total cost is almost $ 100 to set two computers and printers.
Telephone network network can be a simple, cost -effective solution for setting up a home network. Other technologies include a power plant network, wireless and Ethernet. Everyone has its advantages and disadvantages that should be considered before selecting the technology best for your needs.
