Ok, let me give my spill on DSL vs satellite internet. If you live in a super rural area and your telephone cables haven't been updated since the beginning of telephone services, ain't gonna happen. Essentially the old cables had a lead outer jacket with paper insulators around your copper conductors. Phone companies will not usually even try to push DSL down these old lines because they are so prone to a condition known as crosstalk which can not only mess with your old computer modems but it'll cause a world of trouble for a DSL modem. As for your DSL service, the phone company needs to a switching station everything 3 miles in order for DSL to work. What does that mean? If you live more than 3 miles from your closest phone switching station DSL IS NOT GONNA HAPPEN. Note also the farther you live from a switching station the worse your internet is going to be due to line attenuation and noise.

Now onto the subject of satellite internet. Alittle background on me. I was in the military for 8 years doing wireless communications and I worked as a LMR and satellite tech for a government agency for the past two years so heres the deal on satellite. Hughes net isn't bad if you aren't doing alot of heavy downloading but hughes and all other providers advertise their services in a somewhat misleading way I'll explain. Basically the cheap home plans three different things to cheapen things up as much as possible.

First they use a small reflector IE dish. They should use a 1 meter dish or larger IMO but you'll see that most home service providers give you a .75 meter dish. Without getting too technical think of the reflector (round part of the dish that everybody thinks of being the dish) as a concave mirror. A bigger mirror is able to focus more light than a smaller mirror right? RF coming from the satellite in space behaves much like a light. Thus the smaller the reflector the harder it is to see the satellite signal in bad weather. Think of it like this its easy to see someone's brake lights in the middle of good weather but what about a snow storm? Number 2 reason your BUC or Block Up Converter on these home Hughes Net systems is only 1 watt. This is very small particularly when combined with the size of the reflector. Think of the BUC as your transmitter or in this case being we are explaining a flashlight. That light in this case is now your RF energy from your BUC going to the satellite in space. Now a lower power light is more likely to get blanked out by things like snow, fog, rain, and cloud cover isn't it? Most of you have driven in a blinding snow before and not be able to see infront of you?

And the third thing about why the Hughes net service is so slow is because of their bandwidth manager policy IE you use it too much and they throttle back your connection for a given time. Also it is contention based. What that means is that they have X number of users on a given carrier (their satellite dish on their end). Most of the Hughes plans I've seen are close to 500:1. When they give you a bandwidth expectation you'll see in the fine print or maybe right there with the bandwidth the contention rate and speed. Basically what that means is that the speed that they advertise is the speed you will see IF NOBODY ELSE IS ON AT THE TIME. Because that is the speed available to all however many of you are using that same carrier.

If you want a better education on home based satellite services start looking here. www.datastormusers.com and look and ask around. You'll find after talking to some folks that you often get what you pay for. If you do opt to go with a Hughes based high speed I highly recommend using a different dish than they use. www.motosat.com makes internet satellite dishes for RV's and such like that that use Hughes and other services. And the dish reflectors and BUC's are far superior to the cheapo units that Hughes sells directly. If you have an RV that you use alot it might make sense to do this.

Today's Featured Article - Memories of an IH Super A When I was ? up to 10, I worked on my Papaw's farm in Greeneville, TN every summer. As I grew older (7), it was the thrill of my day to ride or drive on the tractor. My Papaw had a 1954 IH Super A that he bought to replace a Cub. My Papaw raised "baccer" (tobacco) and corn with the Super A, but the fondest memory was of the sawmill. He owned a small sawmill for sawing "baccer" sticks. The Super A was the powerplant. When I was old enough (7 or 8), I would get up early and be dressed to ... [Read Article]
