Why is 1000mbps internet only guaranteed at 900mbps and what’s the equipment needed to get the 1000mbps advertised?
In: 90
It is pretty much the provider limiting the bandwidth. There may be some technical limitations but if the provider wanted to they could pretty easily provide 1Gbps guaranteed to the on premises router (for the right price).
Wire speed is different from data speed.
Basically, with all the encapsulation protocols and things that “carry” the data, there’s *at least* a 5 or 10 percent degradation … *Just because those ‘lower levels’ of transmission take up the other room+.
It’s similar to asking why postal mail weighs more than just the paper you are sending … Everything that tells it “how to get to the other side” encapsulates (contains) it, and makes up that “extra weight.”
You will need —
– A modem that supports DOCSIS 3.1. 3.0 is the old standard that theoretically hits 1gbit – but it doesn’t in reality.
– A router with 10gbit ethernet.
– A computer with 10gbit ethernet.
Although WiFi standards and speeds are cleverly marketed, you generally will not see *wifi* speeds of 1gbit. You’ll need to be on a desktop computer with the above mentioned equipment to get 1gbps. Some ISPs are purely fiber optic, and it that case, you would not need the modem however.
Bandwidth is a finite resource. Advertised Internet speeds are like plane tickets, they are oversold. It’s the only way to keep costs down and advertise good speeds, it relies on everyone not using their connection to the max all the time.
That’s why busines/industrial dedicated Bandwidth is so expensive. You can pay hundreds per Mbps in that scenario. That’s because the ISP has to actually reserve that Bandwidth whether you are using it or not.
The speed of your connection is determined by the weakest links in your chain to the remote site you are connecting to, and that can be in your local wifi, in the connection between your home and your Internet Service Provider, or further away on the remote legs of the internet all the way up until the site you are connecting to. As such for many people reaching the speed specified in their internet contract, which only specified for the speed locally between yourself and the Internet Service Provider, is something that happens now and then, or may even be a bit of a pipe dream if your line quality is poor.
Although you can work towards your maximum speed by removing weaker links such as ensuring your wifi is faster than your internet connection or using a CAT6 cable, or having the internet provider correct any issues there may be on the line, the most reliable way to get 1000mbps is to pay for a connection that is somewhat faster than 1000mbps while downloading from local sources that don’t have bandwidth congestion.
ELI5: When Data is sent over a network, it is not sent “whole”; it is broken up into small chunks to transmit and each chunk has a “conversation” back and forth between the sender and receiver. The further your data has to travel, the longer it takes for this conversation to take place for each piece of data (this is called latency). This lowers the total amount of data you can transmit over a period of time – ie MB/second because each data chunk has to wait.
Therefore, even though your infrastructure (modem, hub, wiring etc.) might be able to support 1Gb/sec “Bandwidth” , as your latency increases, the “travel time” for communications (data) to go from (or back to) your computer to (or from) the destination (web site, ftp site etc.) increases and your total real life effective Mb/sec throughput decreases.
When there are a few arguably valid numbers you can use to describe something, different people in different positions will be biased to use numbers that benefit them.
In this case the advertisers/salespersons say 1000mbps because that’s the engineered bottleneck speed of any of the standards and equipment used to bring you the internet.
Of course ‘real world’ stuff brings that number down. Dropped packets or frame loss, slow processing, interference, etc.
Lots of people saying to take 10% off which is a pretty conservative estimate.
The next level of hardware after 1Gbps is 10Gbps so any speeds above 1 uses hardware that supports ’10’. ISP’s can sell you a package that offers you 1100mpbs which will get you your full 1Gbps but all the hardware involved would actually support 10,000mbps.
I lived in Germany in the 2005 lived there for 4yrs. They guaranteed set data rates and they delivered. This included wifi.
So when I’m the US and they say they can’t guarantee it, I call them liars.
Anal retentive here. For those using the megabits per second convention, it is Mbps. Not MBPS or mbps (though I’ll accept that as more accurate than all upper case).
Mega*bits* per second. It is not Mega*bytes* per second. Please stop uppercasing the ‘b’.
One reason is because of how they measure it and network limitations.
Lets start by lightly explaining data over-head, data is sent in packets of data and these packets have data added to them explaining among other things what it is and where its going. This means to transfer a 1000KB file you may actually transfer 1050-1100KB of raw data.
Internet Service providers know a customer wouldn’t be happy when they order a 100Mbps service but never get above 90-95Mbps which again is due to the over-head, so sometimes they provide slightly more then the stated service to compensate for the overhead so you still get 100Mbps net (after over-head). But when you order a service that’s 1000Mbps we hit a problem, almost every home network caps at 1000Mbps which after overhead brings you down to 900-950Mbps and because we hit this limit the service provider cant provide a slightly improved speed to compensate.
