Satellite Internet vs. Cable Internet

Cable TV versus satellite television is an old rivalry that can be seen discussed on TV at all hours of the day. The comparison seems to end however when it comes to satellite internet and cable internet access. This seems strange as cable and satellite companies are pushing packaged services over anything else. So, which is the superior Internet service provider, cable or satellite? Here we will examine both and see if we can answer the question.

Cable Internet:

Cable modems allow Internet access through the same lines that over 60 million Americans now receive cable TV. The infrastructure is proven and sound and more importantly already paid for. The coaxial cable allows dual band transmission, one for uploads the other for downloads. Cable Internet offers about as much bandwidth as any consumer customer would ever need boasting downloads of up to 30Mbps and uploads passing 512Kbps in some areas.

Cable also offers a high degree of reliability as it has been in service in many markets for over a decade, and of course the cable companies date back to the early 1970’s. Generally 99% uptime can be expected.

Bundled together, cable TV and cable Internet will cost around $90.00 per month, or around $55.00 for Internet-only. This is comparable cheap for a broadband Internet service, with DSL being a slightly less expensive option in most areas.

Satellite Internet:

Internet over satellite, or IoS Service, is the technology that provides Internet access via a low, geosynchronous orbiting satellite. This means that the static position of the satellite relative to Earth allows customers to maintain connections any time of day.

One serious drawback to satellite Internet access is signal latency. Every data packet sent and received must travel from the consumer’s computer, through the Internet, through a transmitter, into orbital space, then return. The round trip is around 45,000 miles, and can create a great deal of lag. Although satellite ISPs offer up to 1.5 Mbps downloads speeds, the average signal speeds are closer to 512Kbps. Add latency to this and you can see how the connection can be very slow compared to cable or DSL.

Satellite internet access is also far from affordable. The service typically costs around $50.00 to $120 per month. This doesn’t include the equipment investment which can cost around $300.00 to $600.00 or more, and this is most often an upfront cost. This additional cost does not bring any additional reliability. Many customers complain about slow or even no Internet access during inclement weather, and though these interruptions are generally brief they certainly don’t help justify the cost.

Internet Safety for Kids: How and Why Parents Should Learn About the Internet

Are you the parent of a child who uses the internet or the parent of a child who will start using the internet soon? If you are, you should know that the internet is a great way to stay up-to-date on the news, do research for school projects, and communicate with friends, but it can also be very dangerous. As a parent, it is your responsibility to make sure that your child stays safe online. Unfortunately, for this to happen you must know your way around a computer and the internet. Do you?

A child should never know more than a parent does about the internet. At the very least, you should know about the same. If you are looking to block adult websites or websites that have offensive language, it will not do you any good if your teenager knows ways to get around the parental controls that you set. That is why it is important that you know how to use a computer and the internet or learn if you don’t know.

Another reason why you should be well educated on the internet and computer use is because you are better able to fully understand the dangers of them. You may hear that an internet predator approached or kidnapped a child on the news, but you may automatically assume that it will not happen to your child. Unfortunately, until you understand how the internet works, you really have no idea. Does your child use internet chat rooms or social networking websites? If so, do you know how easy the internet makes it for someone to create a whole new, fake identity?

A good understanding of computer and internet use can better enable you to protect your child. Do you know that Internet Explorer, the browser that comes standard, has a free parental control option that just needs to be activated? A few easy steps and you can have certain websites blocked from your child. Unfortunately, you won’t know this if you don’t know all that you can know about the computer or the internet. Speaking of the internet, additional online safety tools for parents can be purchased online as well.

Now that you know the importance of staying in the know about the internet and a computer in general, you may be curious as to how you can go about doing so. The good news is that there are a number of ways that you can learn all that you need to know about computer and internet use. A few of these ways are outlined below for your convenience.

Teaching yourself is an easy way to learn about the internet and computer use. In fact, what better way is there than to just jump on the computer and see what you can find. For starters, examine your computer or your internet browser for free internet safety tools for parents. You may also want to visit some of the websites that your child visits, just to see what they are subjecting themselves to. Visit their online profile for MySpace, Facebook, or another social networking website. Does it make you uneasy? Are the discussions taking place in your child’s favorite chat room too adult?

You can also ask a trusted friend or relative for help. Do not ask your child or teenager for help though. If they know that you want to set up parental controls or keep tabs on their internet use, they may withhold important information from you. Instead, invite a trusted friend or relative over for coffee and lunch and let them show you the ins and outs of the internet. All you really need is a couple of hours.

You can also take an internet or computer education course. These courses are sometimes offered for free or for an affordable fee by local community groups, colleges, or vocational training centers. In fact, see if your child’s school offers anything. Some schools host informational seminars for parents on internet safety about once a year.

Satellite Internet Wireless

When we use the terminology satellite internet wireless, this is really a misnomer because we think of wireless internet as a connection to the internet that does not require any wires to hook up and get online. For example, as I sit here working on my laptop computer, I do not need any wires to connect to the internet – all I need is to be close to a router which we have hooked up – with a wire, I might add – to our main desktop computer. With satellite internet wireless access still requires the use of a coaxial cable to connect to the internet. The cables run from the satellite to the modem in order to connect your computer.

However, when we speak of satellite internet wireless, my laptop would probably work the same way. The desktop would be connected to a router. The desktop would have the modem which would be connected to the satellite through a cable which we would hook up to a router thus making my laptop completely wireless. The thing about satellite internet wireless connections is that it is a simple process to hook up the desktop with just one wire running from the satellite dish and into the modem port with one coaxial cable.

With satellite internet wireless, you are going to get a lightning fast internet connection, but it is not always reliable when you consider that interference like rain, wind, and snow can hinder satellite access. Of course, to have a satellite dish wireless system, you must have a clear view of the southern sky with no trees or barriers to block the signal. This is because the orbiting satellites are over the equator area.

What is amazing about satellite internet wireless connection is that up to five thousand channels can be simultaneously served by a single satellite. When you consider we have hundreds of satellites in space, that makes it much easier and much more reliable than any other internet connection you can find. Some satellite internet wireless services still require you have a dial-up or modem connection for information you send to the internet, but that would defeat the purpose, so the way technology is working right now, advances are being made to make satellite internet completely wireless.

Satellite internet wireless technology is great for people who live in rural areas and who do not have access to normal high speed internet access. However, there are downfalls, so you need to be completely aware of the advantages and disadvantages before you sign on the dotted line and then check out your other options as well. Satellite internet wireless is a great option for you if you need reliable and fast internet.
