Why? Our current encryptions schemes aren't really dependent on the type of signal....

lets start with channel bonding.. great ! but.. separation occurs when nearby 802.11 wireless access points are detected. This is part of the standard it cant be switched off and for good reason to reduce co-channel interference. Think about it, if you have a clean RF environment then you can have more bandwidth, if you don't sort that out then don't expect for everyone else to be interfered with or go slow just because you want the fastest speed.

one of the new additions to AC is MU-MIMO ((multiple user)) this allow for dedicated streams to individual clients which is good for giving priority devices dedicated bandwidth, if you want all of the streams then thats good but again any bonding can come undone if other local wireless is detected which in 90% of cases is true ((next doors sky router for example)) further more with spacial multiplexing you get a better picture of quieter signals so again your router will unbond if it hears 802.11 wireless from potentially quite far away.

There is also some marketing fluff here, 54mbps on 802.11g/a is actually 22mbps each way and there is a good few mpbs overhead as wireless management frames take up a lot of bandwidth. your realistically looking at a real world transfer rate of 3 mega bytes per second on a a/g connection so by that logic with single stream unbonded N your are looking at 9-10 megabytes per second (for the whole access point) its not exactly slow but id expect in real world tests for a 1gig wireless connection to peak at 75-80 megabytes per second vs 125 megabytes for LAN (correct me if im wrong) and this can only happen in a clean environment with like wise hardware and drivers.. so if we half that for bonding then we get the magic number of about 35 megabytes to 40 megabytes per second transfers (450mbps)

I think the main point is that wireless is a dynamic channel / speed capable medium with many different MCS rates, it will change on the fly depending on the specific environment and provide the best that it can given many factors. In the case of N or AC the actual benefit is a cleaner much less disrupted data flow in the home. People wanting to reach that magic transfer number will be of a fairly low percentage.

its still enough for streaming even 4k video or any rate of HD audio to multiple clients at the same time ! for storage and large transfer / imaging you use LAN obviously

If 100MB is the fastest you can get, why spend all that money, research and working hours on a product that can go that much faster?

Guess you don't do any networking at home. This is for intranets, users who have media hubs in the household who wants to share and stream HD content wirelessly.

2) What is beam forming and how will it change the fact waves lose wall penetration power every time you up the frequency.
3) Since I'm not convinced that my number 2 is negated i still stand by it, and to add you said 256QAM WILL allow more simultaneous signals. By using the word "will" does it mean that its not implemented yet?
4) your 4 doesn't make sense. People said the router is pointless due to the fact internet speeds isn't available in the theoretical speeds the router is rated at. I never mentioned that 1Gbps home networks are useless. In fact if you want a fast home network your best bet is power-line.
5) an opinion really. to me this is worthless, but to you it obviously is worth something

1) Look at industry.

2) I linked you an article on beamforming. It can make up for the wall penetration loss by improving the total signal through the aggregation of multiple adjusted signals.

3) 256QAM is more than 64QAM... by definition. There is more signal processing to reduce the increase noise sensitivity BUT it allows more channels. Noise can be processed, limited channels cannot (without "tricks").

4) The thing only has a 1GbE WAN port anyways. High-throughput wireless is mainly for LANs. Of course Netgear realizes that virtually no one has 1Gbps Internet so "the fact that internet isn't available at that speed is irrelevant.". Power-line is not the best bet for everyone:
- a) older wiring
- b) apartment complexes
- c) noisy lines (i.e. due to other appliances)
- d) not everyone wants a hardline

5) You made the statement of fact "Due to all reasons above this device is worthless, impractical, and a waste of money." Note, that you did not mention "in my opinion" or "to me" anywhere.
Once again...

People would actually use wireless at a Lanparty? rolleyes.gif

A cheap switch and a bunch of cables is an infinitely better solution.

100mb on more than 1 pc at once
I should game.

The benefits of a good wireless router for a lanparty greatly outweigh the consequences of running around a small room drunk with heaps of cables everywhere. I can attest to this.thumb.gif

Running? At LAN parties? tongue.gif

I've seen lots of tripping, ankle banging, knee busting, and being stepped on, (lol) but never much running, especially drunk! tongue.gif
