Woah....

And to think I thought my current comcast cable modem was fast

This thing is blazing fast!! It makes current household broadband look like dial-up by comparison.

i want 2 in a teamed connection

Cool. Will be able to hit the forums crazy fast

 

[avaserfi]

Wow, that thing is blazing fast...sign me up!

How fast will it really be? I mean... I have a cable modem @ home thats said to do 7mbps. My approximate download speed over the internet is 150-200kbps. I mean... I really think that the guy was directly connected to his server! lol How about a real-life demo and specs?!

One thing I don't get is that they are implying that the modem is holding the speed back? How so? And, why is it they can throttle it or increase it for more $$?

I want that Verizon now. That would be plenty fast for me, 5mHz up, 50mHz down.

I must be one of the lucky ones, because my cable speed has always performed as advertised.

My DSL is as fast as my Comcast was previously (and costs less), and even via wireless it is pretty darn quick.

Old news. This type of service (100mbps) is already available in Japan and Korea for like $30/month.

I want WiMax so i can use my VOIP anywhere i travel within 30km (45 miles?)radius..

Downloading takes time because of your source, the other end is likely running something else and bandwidth gets stepped on when there are others downloading.

The Comcast service I have now is the basic service, I can upgrade my service to a higher speed using the same cable modem, all I need to do is make a phone call and request the change. So the modems now are quite capable.

Try some of these places for a speed check.

Yes, the sender can be at fault. By issue is why the upload speed is throttled so low on comcast 360 something on basic..

No, 30km is 18.75mi.
A mile is 1.6km.

The article says, "It bonds together four cable lines but is capable of allowing much more capacity." Does this mean they'd need to run 4 cable lines to your house for you to take advantage of this?

No, it means that multiple physical cables that run from the cable company to the taps on your street can operate logically as one physical cable. The logic is in a switch that routes the packets arriving on different physical cables to the one cable that feeds your house.

Sounds neat, but as seth mentioned the speed at which you download any data is limited by the speed at which it's being sent so if you got this service any time soon you aren't likely to see a dramatic increase in performance.

Ok..i got it all reversed and wrong.. I knew many were much smarter than me here..

Thanks for clarifying, now for a follow-up question. Does this mean that the single cable that currently feeds my house could technically push 4x more data than it currently deals with?

Yes and a whole lot more. The typical RG6 cables you find inside your home are sweep tested to 3 GHz or more (which means that they can carry frequencies that high with no more than some specified loss - usually 3 dB).

But we're talking digital data here so it depends on how the data is encoded (currently MPEG2), how compressed it is (currently a lot!), and what communication protocol is being used (currently TCP/IP). If your house were the only one on a particular tap you could easily obtain multi-gigabits per second. The reality though is that there are usually 100 or more houses on each trunk line and we all have to 'share'. When the cable companies install more physical cables and implement this channel bonding scheme they are talking about we'd be able to use more of the capacity of the fiber optic lines that feed the trunks in each neighborhood...and you can bet the price will go up to pay for the cost of all that new infrastructure.

Not about being smarter or not as I have my fair share of weakness and not knowing I just happen to know this tidbit info from school and charts. We all have weaknesses and strengths. Don't underestimate yourself.
