Now, we'll talk about power-line networking and the technology used to make it happen. We'll also discuss the advantages and disadvantages of using a power-line network.
Pros and Cons
There are two competing power-line technologies. The original technology is called Passport, by a company named Intelogis. A new, soon-to-be-available technology is called PowerPacket, by Intellon. PowerPacket has been chosen by the HomePlug Alliance as the standard for power-line networking.
Here are the advantages of a power-line network:
- It's inexpensive. (This author bought a complete Intelogis' PassPort kit to connect two computers for $50.)
- It uses existing electrical wiring.
- Every room of a typical house has several electrical outlets.
- It's easy to install.
- A printer, or any other device that doesn't need to be directly connected to a computer, doesn't have to be physically near any of the computers in the network.
- It doesn't require that a card be installed in the computer (although there are companies working on PCI-based systems).
There are also some disadvantages to connecting through power-lines, particularly when using the older Intelogis technology:
- The connection is rather slow -- 50 Kbps to 350 Kbps.
- The performance can be impacted by home power usage.
- It can limit the features of your printer.
- It only works with Windows-based computers.
- It uses large wall devices to access an electrical outlet.
- It can only use 110-V standard lines.
- It requires that all data be encrypted for a secure network.
- Older wiring can affect performance.

New power-line networking products are based on Intellon's PowerPacket technology.
- It is very fast, rated at 14Mbps.
- It 'avoids' disruptions in the power-line, maintaining the network's connections and speeds.
- It does not limit the features of your printer.
- It can be compatible with other operating systems (depending on driver availability).
- It may have the necessary circuitry embedded within the device, necessitating only a standard power cord to access an outlet.
- It works independent of line voltage and frequency of current.
- It includes encryption.
- In tests, it showed no signal degradation due to older wiring.
Now let's find out how each of these technologies works.
Intellon's PowerPacket technology, which serves as the basis for the HomePlug Powerline Alliance's forthcoming standard, uses an enhanced form of orthogonal frequency-division multiplexing (OFDM) with forward error-correction, similar to the technology found in DSL modems. OFDM is a variation of the frequency-division multiplexing (FDM) used in phone-line networking. FDM puts computer data on separate frequencies from the voice signals being carried by the phone line, separating the extra signal space on a typical phone line into distinct data channels by splitting it into uniform chunks of bandwidth.
In the case of OFDM, the available range of frequencies on the electrical subsystem (4.3 MHz to 20.9 MHz) is split into 84 separate carriers. OFDM sends packets of data simultaneously along several of the carrier frequencies, allowing for increased speed and reliability. If noise or a surge in power usage disrupts one of the frequencies, the PowerPacket chip will sense it and switch that data to another carrier. This rate-adaptive design allows PowerPacket to maintain an Ethernet-class connection throughout the power-line network without losing any data.

This card plugs into a PCI slot in your computer and into a wall outlet to create a power-line network.
The latest generation of PowerPacket technology is rated at 14 Mbps, which is faster than existing phone-line and wireless solutions. However, as broadband access and Internet-based content like streaming audio and video and voice-over-IP become more commonplace, speed requirements will continue to increase. Along these lines, Intellon's OFDM approach to power-line networking is highly scalable, eventually allowing the technology to surpass 100 Mbps. Products based on the current revision of PowerPacket are expected to be available by the third quarter of 2001.
The older power-line technology used by Intelogis relies on frequency-shift keying (FSK) to send data back and forth over the electrical wires in your home. FSK uses two frequencies, one for '1's and the other for '0's, to send digital information between the computers on the network. (See How Bits and Bytes Work to learn more about digital data.) The frequencies used are in a narrow band just above the level where most line noise occurs. Although this method works, it is somewhat fragile. Anything that impinges on either frequency can disrupt the data flow, causing the transmitting computer to have to resend the data. This can affect performance of the network. For example, this author noticed that when he was using more electricity in the house, such as running the washer and dryer, the network slowed down. Intelogis includes line-conditioning power strips with its network kit and encourages you to insert them between the wall outlet and your computer equipment to help reduce the amount of electrical-line noise.
Because the current crop of power-line networks are designed to work on 110-volt electrical systems, the technology is not very useful to countries outside of North America that use different standards.

A power-line network provides access all over your home.
How to Install a Power-line Network
The physical connection between each computer and the Intelogis power-line network uses the computer's parallel port. A wall device is plugged directly into the electrical outlet (it will not operate properly if plugged into a surge protector).
A parallel cable is plugged into the wall device and into the parallel port of the computer. The power-line network must be the last item connected to the parallel port. For this reason, if you have anything else connected to the parallel port, such as a scanner or Zip drive, it must have a pass-through for the parallel port. Unless you have a second parallel port on your computer, your printer must be connected to the network through a wall device of its own. Something to keep in mind is that current power-line networks do not support bidirectional printing. 'Bidirectional' means that data is sent in both directions, allowing your printer to send information back to your computer, such as how much ink is left and if there is a paper jam. This will not keep your printer from working, but it is worth noting that you will lose the use of such features.
Initial PowerPacket devices will connect via a USB or Ethernet cord from the computer to a small wall adapter. Subsequent devices will have the circuitry built in, meaning the only connection needed would be the power cord.
Once the physical connections are made, installation of the software is a snap. The software automatically detects all nodes (computers and printers) on the network. Whether your Internet connection is by cable modem, DSL or normal modem, the included proxy server software allows you to share the Internet with your other computers. You can easily add computers by simply plugging a new adapter in and installing the software. Additional printers can be added using the printer plug-in adapter. File and printer sharing is done through Windows.
There are two common types of home networks: peer-to-peer and client/server. Client/server networks have a centralized administrative system that provides information to all of the other devices. Peer-to-peer means that each device can talk directly to each other device on the network without consulting a central system first. Intelogis' Passport technology uses a client/server network. The first computer that you install the software on becomes the Application Server. In essence, it is the director of the network, controlling the flow of data and telling each device on the network where to find the other devices. Intellon's PowerPacket technology uses a peer-to-peer network.
There are two other networking technologies to discuss: phone-line and wireless networks. Click on the title to go to one of these articles for more information, or proceed to either A Word About Macs or The Future of Home Networking.

What is a LAN?
LAN stands for Local Area Network. It is a network that we can install on 2 or more computers and allows these computers to talk directly with each other. It is kind of like the internet, but on a much smaller scale. The internet allows us to connect with computers all over the globe, while a LAN is limited to a small area, such as a home or office.
LANs are used by businesses as well as personal users to upgrade the capacity for information transfer, as well as share utilities such as a printer or an internet connection. Through a LAN you can also directly connect computers in order to play in multiplayer computer games, such as Half-Life or WarCraft III.
When the computers are connected, there are two primary types of connections. The first of these is a client/server network. What this means is that one computer is the server, which hosts the majority of the information and directs all info. If you have five computers on a client/server network, any computer must first talk to the server to talk with any of the other client computers.
It is contrasted by the peer-to-peer network, where all computers are equal in the connection, and any computer can talk directly to any other computer. If your system only has two or three machines, the difference between these two network types is minimal.
A LAN requires two components: hardware and a software component. The hardware is the actual physical connection that allows your computers to communicate with each other. The software component involves the proper configuring of the two systems so that they are in sync with each other once we create the physical connection.
Options for Connecting Your LAN
When it comes to the actual hardware involved in setting up a LAN in your home, there are many different options available for you. They are:
- An Ethernet Connection (Computers are directly connected either through an ethernet hub or using crossover ethernet cable)
- Powerline Networking (Computers talk to each other through power lines)
- Phone line Networking (Computers talk to each other through phone lines)
- Wi-Fi (Wireless Networking)
Each of these options is very different, and require very different hardware to install. However, once we complete the hardware installation, the configuring of the computer’s software to talk to each other is the same process no matter what kind of connection you have.
Installing a LAN Using an Ethernet Connection
If your computers are in relative proximity to each other, either in the same room or in a place where wires will not have to run very far, an Ethernet connection may be your best choice for connecting your LAN.
Ethernet and exceptionally Fast Ethernet connections have higher transfer rates than most of the other connection types. (Fast Ethernet can transfer information at a speed of 100 Mb/s!). However, unless the computers are nearby, it might be awkward or even impossible connect computers over ethernet without hardwiring cables into the walls.
An ethernet connection is the most direct networking connection option. Generally, a single wire is used to connect one computer to the other. It is called a crossover ethernet cable.
An ethernet cable is five separate wires twisted with each other. At both ends of the cables are jacks where these wires connect into a port, similar to a phone jack. (An ethernet jack is also approximately the same size as a phone jack).
When the wires come out of the cable in the same order they entered the cable; then this is a straight ethernet cable. If the end wires are in opposite order from the beginning wires (or crossed over), then we have a crossover ethernet cable. For a direct cable ethernet connection to work, you must have a crossover ethernet cable.
Connecting the computers is simple with a crossover ethernet cable. Firstly you must make sure that there are ethernet ports on both machines. Many computers these days come with an ethernet port as standard. To check, look at the back of your computer. The ethernet port looks just like a phone jack for a modem line but has an emblem beside it with three computers connected to each other.
If you do not already have ethernet ports on your computers, you will have to install them. Ethernet ports are cheap and cost about $25. Most ethernet ports connect to a PCI slot inside your machine.

If you have three or more computers in the same room you want to connect; you will need an ethernet hub. It is a little box that allows you to connect straight ethernet cables to it from each computer. It will direct all information over the LAN.
Power Line Networking
If you have computers spread across the house, then powerline networking is a cheap and easy way to connect your computers. Rather than having a direct wire connection between each machine, computers get the connection to a particular power adapter in your power outlet, and data travels between computers via the power lines already existing in your home.
There are two main competitors in the power line networking field. One is Intelogis, which offers its Passport technology to connect computers. The other is Intellon, whose technique is called Power Packet.
The two cost about the same, and are about the same quality although Power Packet is somewhat faster than Passport. Passport products generally connect to your computer through the parallel port (the same place your printer is hooked up), while Power Packet products connect either through USB or Ethernet ports.
Deciding which of these two solutions to use is entirely up to you. The cost is generally between $60 and $80 for either one to connect two computers. (Cost increases if you wish to connect more than two computers via this method).
Installation is simple. You must install the software that allows the computer to recognize the new connections, then plug in the cables into either your parallel port or your USB port. These cables then plug into a special power adapter into your power outlet. Once we connect the wires on both computers, we can set up our LAN.
Powerline networking also allows for the connection of a printer through the power lines. It is particularly useful with Intelogis’s product, as it can be difficult to hook up your printer if you only have one parallel port on each machine.
Phone Line Networking
Phone line networking is similar to power line networking in that it uses already existing wiring in your home to connect computers. Rather than using power lines, however, it uses phone lines.
To connect your computers to a wall-jack, you must either have a special phone networking card installed in your computer (a regular modem jack won’t work) or have a phone line adapter that will allow you to plug in the phone wire into another port. Most phone networking products use cards that must have in your machine (making phone networking more difficult that powerline networking).
Once you have your card installed or your adapter ready, you need merely plug in all computers into the nearest phone jack, and they will then be able to be configured for your LAN. (Note that if you have two or more lines in your home, the computers should have the connection to the same phone line).
The newest technology in the networking field is wireless networking or Wi-Fi. With Wi-Fi, you require no cords, cables or lines at all. Computers talk to each other via radio signals.

Computers cannot talk directly to each other via a Wi-Fi network; however, they must have a router in between them. It is a small box that you plug in at some location and is generally also where you plug in your DSL or cable internet connection if you want to share internet between computers.
The router has a range of about 100 feet, which should cover most every area in your house. The signal sent by the router is not affected by floors, ceilings, walls, doors, etc., so you do not need direct line of sight between computers and the router.
Intellon Network Services
Once you have your router installed, you must have your wireless adapters installed into your computers. These adapters generally plug into either a USB or ethernet port. Once router and adapters are in place, you are ready to set up your LAN on your computers.
Configuring Your LAN
Once the actual hardware connections are in place, the next step in installing your LAN is setting your computers to talk to each other. We will discuss how to do this process in Windows.
To begin, you must open your Control Panel. Once in the Control Panel, you want to go to Networking Options (Or Network and Internet Connections). Click on the Setup or change Home or Office Network, and this will open up a wizard that allows you to configure your new LAN.
When you go to configure your LAN, you must make sure that all computers you are attempting to connect are on, and that if you are going to share an internet connection that this connection is active.
The wizard will then automatically check your network both for computers on the net and for the shared internet connection. You will have to choose a host computer from which the internet connection is to be shared (the computer that has the internet connection). The host computer should be the computer that you first configure for the LAN.
After that, the wizard will direct you through any other processes that might be required. It is very rapid and straightforward. Afterward, you must log onto the other computers and configure the LAN there as well.
Once you have finished the configurations, you are ready to start using your LAN!
