I'm just curious what the difference between one-way and two-way sattelite internet is? From what i've been reading I think I understand the difference, but I just want to confirm it with someone that may know for sure or link me to some places that can clear up my questions. Thanks to those who help.

With one-way satellite internet, you transmit your requests (your uplink) via a dial-up modem. Your requested data is returned to you (downlink) via the satellite. With two-way satellite internet, you send and receive via your satellite dish. Unless you send a lot of data, taking in to consideration of the roundtrip times (500 to 900ms) of satellite communication, a one-way satellite internet connection may be more responsive than a two-way system where the dial-up modem would typically be delayed around 150 to 200ms. Some two-way satellite systems also employ a dial-up connection as a backup for faster response data, and only using the satellite for high bandwidth uses...

Thanks for the detailed response. Does this mean with one-way sattelite internet the phoneline would be blocked, still? Also. Does this mean that any information I received such as if I was to download or surf websites would be sattelite fast? Also. How does the uploading work? Such as if I was to upload a picture or video would this also be sattelite fast or not? Please help to clear up these questions.

Thanks for the BR... ^_^ Sadly, yes... since the only way you can send out will be via the dial-up modem, your phoneline will be tied-up... Regarding the download, there are a number of factors that affect your downstream "speed" but, it's dependant on the satellite downstream... your upstream (uploading) will be limited by the dial-up connection... IIRC, the upstream for a 56k modem is 33.6k, which realistically will give just under 3kBytes upload...

Alright then yeah, kind of how I thought it worked. Frustrating but i'm not much of an uploader. More of a surfer n' such. Still frustrating to know that the upload speed will be sloowwww. Good to know the download speed will be much faster, though.(At least from what I got from what you were saying.) So basically the only downfalls to one-way sattelite internet is a blocked phone-line & slow upload speeds? Everything related to browsing, downloading, etc. is sattelite speed?(basically anything where you aren't sending out information but receiving it, right?) One more thing. Does this mean that phone service like Skype wouldn't be an option or well, give me an idea if it will be. If you used a normal wireless phone compatible with skype, would that mean hooking it up to a USB port or something along those lines? Orr! Would it simply not be an option? If not, any suggestions? The problem arising now then is still having to pay the rip-off prices phone companies charge but if you need to use Dial-up with a one-way sattelite internet connection I suppose that can't be avoided?(I guess you could limit the phone service dramatically to pay a lot less while still keeping it, and then making something like skype the primary phone service though, eh?) Feel free to help me with this if you want. Would be really nice.

Not positive, but I would think it would have to do with the streaming process. If it's only one way, you can stream information from the sattelite down to your unit or computer, and if it's two-way, you can stream/beam your stuff up as well as download information. One way sattelite would probably be info like: you can read your emails but not send one back. Two way would let your end be interactive rather than just receiving info. Couldn't find any info, but this is what my take on it would be.
