Most folks want that laptop for work, school, or college. Most laptops these days are Wi-Fi enabled. That means that they have the wireless hardware and software built into the computer. To the average consumer, wireless is a form of magic. You turn it on and it works, right? Not always. Understanding the basics to wireless will help avoid frustration and headaches.
First, before we get into the basics of wireless networking, I have a few opinions to express.
It seems that everybody wants to go wireless with their laptops and desktop PCs. Wireless for laptops makes sense, since they get moved around between work and home and points in between. You can always connect using the Wi-Fi network at work or steal bandwidth from someone else. There are hotspots all over. There are ethical questions involved with borrowing?your neighbors signal. Let your conscience be your guide.
Wireless for desktops is an open subject. Since most of us usually set our desktops up on our home or office workstations, they tend not to move around. The only benefit of having a wireless desktop is that you dont have the expense and trouble of running Ethernet cable around your house. If you are not a DYIer, an Ethernet cable installation is an extra outlay. If youre lucky, your present PC is only a few feet away from your Broadband Modem. I personally prefer to have all my stationary PCs hooked up with Cat 5 Ethernet cables. That way I dont load up the wireless bandwidth on the router. Well talk more on bandwidth later.
There are hardware requirements to wireless networking. These are the things you need to communicate.
At home you need:
- (1) a Broadband internet connection (Cable or DSL modem),
- (2) a router to broadcast the wireless signal,
- (3) a wireless enabled computer.
The Broadband internet connection gear should already be present. Thats the Cable or DSL Modem that your Internet Service Provider installed when you got their service. Its connected to the Cable or DSL filter connection coming from your wall. The Modem has two connectors as a rule. One for the Cable or DSL data into the Modem, and one RJ45 connector you probably have connected to the computer you have in service now.
Youll need to unplug the Ethernet cable between the computer and the Modem. Reconnect that cable to your wireless router. It goes into a RJ45 connector usually labeled WAN?for Wide Area Network. The only other connection you will need to make is to connect another Ethernet cable between from one of the wired ports on the back of the router to your PC. There are usually 4 of them. Any one will do to reconnect your existing PC so its on the network. The existing PC will get its internet connection through this port. Your routers default settings should allow you to start connecting to your Wi-Fi enabled computers.
If all the cables are correctly placed, you should now be able to get on the Internet from you existing computers and your wireless computers.
Some quick notes of interest:
- (A) Your Wi-Fi router is transmitting and receiving in the 2.4MHZ range. So are your Wi-Fi enabled computers. This is the same frequency range of a number of cordless telephones. You may have interference on your cordless phones once the Wi-Fi network is installed. If this occurs youll need to get 5.8 MHZ phones or put up with the noise.
- (B) One of the most common questions I get is ?strong>I bought a wireless laptop and I cant get on the internet. Why not??If your wireless router is installed properly, then your wireless laptop may need configuration. Go to your Network Places or Network Neighborhood for a wizard to help you set up your computer for wireless.
- (C) Bandwidth is the volume of traffic you can sustain through your network. The more devices using the Wi-Fi network, the slower the network uploads/downloads will be.

When you connect to the Internet, you might connect through a regular modem (dial-up), through a local-area network (LAN) connection in your office, through a cable modem (Cable Internet) or through a Digital Subscriber Line (DSL) connection.
For me DSL connection is the most cost-effective solution that home based and small business office can leverage to grow a business. It is not only widely available but its reliability and high-speed capability is what it makes one of the most preferred access service.
DSL is a broadband high-speed connection that uses the same wires (2-wire) as a regular telephone line. Simultaneous use of voice and data (internet) one can log on to the internet while also using the line to make voice calls. The speed connection is much higher than a regular modem which can hit to a max of 56Kbps only. DSL can use existing phone line or delivered as stand-alone DSL connection. The company that offers DSL will usually provide the modem as part of the installation.
A drawback with DSL is that a DSL connection works better when you are closer to the provider's central office. The connection is faster for receiving data than it is for sending data over the Internet. The service is not available everywhere again owing to distance limitation.
All types of DSL service fall into one of two basic categories: symmetric and asymmetric. Symmetric types of DSL support the same bandwidth between the subscriber and the service provider in both directions.
Asymmetric types of DSL or ADSL support relatively more bandwidth in the downstream direction (from the service provider to the subscriber) and less bandwidth in the upstream (from the subscriber to the service provider). ADSL is popular among Internet Service Providers (ISP).
ADSL uses two pieces of equipment, one on the customer end and one at the Internet service provider which is usually telephone company or other provider of DSL services. At the customer's location there is a DSL transceiver also called Customer-Premise Equipment or CPE, which may also provide other services. The DSL service provider has a DSL Access Multiplexer (DSLAM) to receive customer connections.
A DSL Modem or CPE is like transceiver equipment, it transmit and receive data packets (information) over ordinary telephone cable. This data packets are actually digital signals but since digital signal cannot travel far, the DSLAM from the ISPs head end transform the signal from digital to analog signal for transmission over an analog channel (two-wire telephone cable) usually at a distance of up to 5Km from central office and the DSL Modem or CPE converts the signal back to digital. The DSL Modem is the equipment where data from the user's computer or network is connected to the DSL line. DSL Modem can connect to a customer's equipment in several ways, though most residential installation uses USB or 10 base-T Ethernet connections (RJ-45).
The DSLAM at the service provider is the equipment that really allows DSL to happen. A DSLAM is the point-of-contact where a dedicated, high-speed link to the internet called backhaul connection is terminated. An E1 (2048Kbps) or T1 (1536Kbps) Dedicated Internet is an example of a backhaul internet link that can be use to service between 80-100 DSL subscribers. DSL technology is the reason why internet connection is becoming cheaper by the days. It is able to share or distributed for greater use a dedicated connection (backhaul) to several subscribers while maintaining quality of service. Cost-of-service is significantly lowered.
The DSLAM takes connections from many DSL subscribers and aggregates them onto a single, high-capacity connection to the Internet. DSLAMs are flexible and able to support multiple types of DSL in a single central office, and different varieties of protocol and modulation. In addition, the DSLAM may provide additional functions including routing or dynamic IP address assignment for the customers.
ADSL is a distance-sensitive technology: as cable connection's length increases, the signal quality decreases and the connection speed goes down. Connection is much more stable the nearer the user is to the central office. With a maximum 18,000 Feet (5,640 meters) effective service length, some ADSL providers generally limit distance it serves to a max of 3.5Km. Beyond this some subscribers enjoy speeds below the promised maximums.
Bursting and Committed Information Rate (CIR) are two factors to consider in choosing a DSL service. Remember, DSL is a shared internet connection service depending on the port configuration or package variation of the service providers. Bursting is the term use to describe a service which does not guarantee a certain speed. Connection bandwidth may vary from maximum of the port-speed subscribed (as provided by the ISP) to a minimum of as much as 32Kbps. DSL that offers Committed Information Rate (CIR) or minimum guaranteed speed is much more desirable for it assures a sure connection to the international internet gateway.
In choosing an ADSL package fit for your home-based or small business requirements, try to ask the ISP of the recommended count of users and type of application that the DSL package can support. Usually, residential package can support only up to 1 or 2 PC. However, with competition and greater availability of other broadband internet access, ADSL packages currently being offered by ISPs can support all type voice, data and video applications and at greater speed.
