So, Waylanders post made me think about usuage of power for stuff in our house - in the cellar i have a bog old Nortel 48 port switch humming away - it cannot be very power friendly at all - the fans are on all the time and it makes a racket. Are there any low power consumption switches (gigabit)about that are 19" rack mountable? Oh, and not very deep.... :-)

And i just looked the switch up that I have now - the max usage is 135W (i am not using all 48 ports but i guess that's really high!)

I was all set to make a recommendation until I saw the layer 3 requirement. Hmm. I know a few that will let you power off the LED's but I can't imagine that makes any significant difference.

Don't worry about Layer 3 - i don't use it much only for fiddling and testing etc. Been looking at some TP-Link ones - any good?

TP-Link tends to polarise opinion, some people love their kit whilst others hate it.  My opinion is that for the price point it's pretty good stuff.  I've got a few bits of TP-Link stuff knocking about and it hasn't give me any trouble.

 

I like HP edge switches, I'm not a fan of their big chassis switches.

Blimey what do you do with a 48port switch in the home??

All sorts of stuff.. I've got about 20 hard wired CAT6 ports in the house that all go to the cellar and terminate there. Then a variety of servers / routers / firewalls for a lab for testing etc for work related stuff.

Think I can beat that number, got a coax ports (for TV) and dual RJ45 ports in every room - no idea what I was thinking when I built the house, maybe it was wifi and cordless phone will never catch on lol

I can never get wireless working very well in my house, thick walls and the signal doesn't seem to go very far. Best I've found so far is Cisco Meraki AP. Working well and very quick!

What's up with wifi for a 1080 stream?

 

Here is a list of the Internet speeds recommended by several popular streaming services:

Netflix

  • 1 Mbps for viewing on a laptop computer
  • 2 Mbps for SD video on a TV
  • 4 Mbps for 720p HD video
  • 5 Mbps for "the best video and audio experience" (according to Netflix)
Hulu Plus

Note: If a TV show or movie repeatedly needs to buffer, Hulu Plus will stop streaming the video and recommend that you downgrade the video quality.

  • 1 Mbps for SD video
  • 2 Mbps for 720p video
  • Over 3.2 Mbps for best quality HD video and audio
Vudu

Note: All Vudu movies are streamed with Dolby Digital Plus 5.1 audio.

  • 1.0 - 2.3 Mbps for SD video
  • 2.3 - 4.5 Mbps for 720p video
  • 4.5 - 9.0 Mbps for HDX 1080p video
  • Over 9 Mbps for 3D HD movies

 

 

Scaling up for multiple streams would possibly become an issue depending on your wifi setup.

Nothing, if you're streaming compressed "HD" video with 2 channel sound from the internet and like the wifi router pretty close to your TV. However, I prefer to watch less compressed Bluray quality 1080p with DTS (or TrueHD) audio and watching over Gigabit, streamed from my server, which doesn't have caching or blurring issues.

 

BTW,  25 Megabits per second is recommended for Ultra HD,  Netflix equivalent to 1080p.

 

Netflix consumes:

Medium (SD: 0.7 GB per hour)
High (Best video quality, up to 3 GB per hour for HD and 7 GB per hour for Ultra HD)

Aha! I've not noticed any issues on my wifi but I must be honest and say it normally goes to my TV which is all wired up at 1Gb.

When the content is remote I can't say I've really noticed any issues. Streaming VirginMedia content to the TV is done over dedicated 10Mb and I've streamed 3D HD from the web without issue.

 

It could of course be I'm not that fussy/blind and I don't notice the difference  :unsure:
