When choosing a broadband connection you will find that many providers offer ADSL or cable broadband, but not both. There are a few simple differences between the two that can help you make a decision about what service to go for. You might have to make a call to the providers under consideration, but it will be worth it to ensure you’re receiving the fastest service you can for your money.
The basic difference is distance versus users. An ADSL connection is a dedicated circuit from the provider to you. The advantage to this type of connection is that, in most cases, the number of people logging on to the service does not have a significant impact on your service quality or speed. Your distance from the telephone company’s nearest “node” or DSL hub will be the biggest determinant of your service quality. There are several internet sites that can give you ideas of hub locations, but calling the providers in your area can give you a better idea of whose hub is located closest to you. Ideally, a hub within 1.5 kilometres is best; quality degrades slightly beyond that, and more precipitously the further from the hub you are. Beyond about 5-7 kilometres your service will be likely to be seriously impaired.
Cable broadband has generally higher transfer speeds, but it is impacted by the number of users. Cable is not a dedicated line to your house like ADSL; it’s shared by all users. This means that as more users log on, the more your speed degrades.
Of course, ultimately, your decision will be based upon what’s available in your area, but if you have a choice between the two, you’ll need to consider hub location as well as the number of people around you who could share the connection when you’re making your final decision.
