Ok, if my work (based out of new york) require's me to have a 500-600kbps upstream for my video calls.. & i'm on Telstraclear Lightspeed and have done a speed test from here to new york and say's i get between 1.5-1.8mbps upstream does that mean i can upstream at 1500-1800 kbps or is that not how it works?

So if i'm getting 1.5-1.8mbps with Telstraclear what would i be able to upstream if i was on Telecom inhome broadband plan? would it be good enough for webcam video calls from here to New york, thankyou

Hi, 

Speed tests usually give your speed in Megabits (Mb) to get the MegaByte value (MB) you need to divide the Megabits by 8.

so if you are getting 1.8 Megabits on a speed test, you are only getting 225 KiloBytes.

Bits are a measurement of speed and Bytes are a measurement of size in this sense.

Thanks,
Ben

Hi, so they are recommending 500-600kb/s, thats 0.5-0.6Mb/s and currently on your TCL cable connection are achieving 1.5-1.8Mb/s (1500kb/s - 1800kb/s) so you have plenty of margin and yes you could put the video codecs rate up to a higher rate, but you will hit your data rate sooner.

A Telecom DSL connection is capable of around 1.0Mb/s upstream rate at best, typically at least 0.7Mb/s or better so should easily achieve what is required.

Cyril

Edit, what software are you using to make connections with your clients.

Doesn't work out to be exactly 1000kbps/Mbps but yeah.

ADSL2+ on telecom/xtra is usually around 800-900kbps upstream

But it comes down to the realtime usage, They may say it NEEDs it, but it may only use up to that (recommended)

Depending on the software used the video encode rates and audio can oftgen be tweaked to lower them anyway.

/edit

Super Cyril beats it again

Ok, so the first post says im below 500-600kbps (only 215kps) and the other one say's i've got room to play, im using a webcam pro 9000 (logitech) and using there software that come with camera LWS 1.1

So Cyril7 is correct not Slingshot?.. how could I play with the software codec to test how much each video is using upstream lower the video resolution in the cam software?

thanks guys your awesome

Results on speedtest are ALWAYS in Mbps or Kbps (Megabits or Kilobits). No need to convert to bytes in this case.

In precise terms a megabit is 1024 times a kilobit. For general use we settle at 1000 times.

Therefore 600 Kbps = 0.6 Mbps (approximately), and conversely 1.8 Mbps is 1800 Kbps (approximately).

If your application requires 600 Kbps (0.6 Mbps) and your connection is giving you 1.5 Mbps (1500 Kbps) then you have more than enough for your needs.
