Re: Anyone understand physics of the electromagnetic spectrum?
said by PastTense:Same way that cable Internet can offer 20 Mbps packages to an entire neighborhood over just four channels. Residential Internet service simply *has* to assume that people will not saturate the connection 99.9% of the time in order to achieve low pricing that the consumer is willing to pay.
I don't see how you can handle 2 million 5 Mbps connections off of one satellite. Could someone explain the physics of this?
EchoStar 17 has 100 Gbps of aggregate capacity. 2 million users at 5 Mbps each would be an oversubscription ratio of 100x -- pretty typical. Per-user guaranteed bandwidth would be 50 Kbps. That's a lot better than the existing satellites, which have single-digit Kbps of per-user guaranteed bandwidth.
Caps should keep users watching the meter and not streaming too many videos, so this could realistically give a couple of hundred Kbps during peak times.
Of course, until the 2 million users actually show up, there will be plenty of bandwidth to spare.
