cat5e vs 802.11ac. dedicated stream throughout

by ajayk78 / June 23, 2013 3:01 AM PDT


I have a structured wiring home on cat5e wiring. With the advent of gigabit 802.11ac standard, I was wondering if it makes sense to build a home network lan on cat5e. Both being giga bit, what is the key advantage of going the wired route.

Would a structured wired network provide me with simultaneous multiple dedicated gigabit speed from a central server to different access points in different rooms, whereas a wireless network would have to share the same gigabit bandwidth across all access points for simultaneous multiple streams?

If that is true, i can see that as a big advantage over wireless.

I'm sure you figured it out.

Multiple access points versus one. Since all WiFi is shared half duplex, by having more access points you do get more wireless throughput.

Since this is new stuff I didn't think you were asking for vaporware but have some idea on what you have now.

So given you have you hardware all ready I thought you may want to know I use the older(?) but available WAPs (or router configured as a WAP) so we don't lose time looking for vaporware.

Still not sure

I guess the more I think about it, both wired cat5e and wireless 802.11ac share the same limitations. A single server connected to the wired LAN through a switch still has to route multiple simultaneous data requests through a single input line and multiple output lines. So in theory the gigabit throughput is split across multiple access points. Maybe there is no strong advantage of wired over wireless, besides the usual security/slightly better performance/reliability etc of wired networks. The advantages of wired don't really justify investing in wiring your home especially with cat5e with 802.11ac standard being ratified soon if you are mainly after throughput. Unless someone strongly disagress with this assessment, I hope this post helps someone else in the same shoes as I am.

802ac is new. Please fasten seat belts, turbulence ahead.
