I moved my most of network to ethernet over powerline using AV500 kit a few years ago, as the WiFi congestion was pretty bad around here and I was getting lots of drop outs streaming video etc. Cheap and effective, and works well. 75-85 megabit rock-solid transfer rates, tested transferring large files.

I still need WiFi for two phones and tablet. I have moved the phones to the 5GHz band, which works better but seems to lack range (the tablet won't do 5GHz). But I have just discovered powerline units that you can apparently set up as dual-band access points - connecting back to the router over powerline and extending the WiFi coverage. Two on order, so I will see how it goes for extending WiFi coverage when they arrive.

Remember 802.11ad is now official with the first kit on display at CES. Seeing 2Gbps on a speed test was pretty impressive!

60GHz means every room in the house will need an AP, I can just see the problems when people start complaining their WiFi is bad because they're not willing to do this.

The 802.11ad-2012 amendment is being targeted at wireless docking, wired equivalent data transfers and streaming of uncompressed video. There is some debate about the use of 60 GHz signals in high density deployments (lecture halls in universities, for example) but I can't see a residential deployment with an access point in each room. You may have a 802.11ad compliant access point in a multi-media room specifically for video streaming though.

I have 5 of these virtual interfaces, with RTS/CTS enabled enabled.

Virtual Interfaces ath0.5 SSID [AP5] HWAddr []

I then have one interface I actually use without RTS/CTS.

The other APs scans the area, determines channel 6 isn't useable for anything (even though only 1 AP/SSID has any traffic on it) and go to the other channels.

Clear skies for me (if I choose to keep it going, which I won't as everyone else must have a pretty bad time on the other channels).

Just got 2 friends off a nightmare 2.4GHz WiFi. They were seated only 3 to 4 metres from the router.

They each just got new laptops with 2.4GHz b/g/n and couldn't understand why they had even more dropouts and very slow WiFi compared to their old laptops (which also had poor WiFi issues).

I counted 8 2.4GHz Wifi devices:

2x Laptops

Mobile phone

Printer

and 3x neigbours with strong signals.

They spent hours trying to get Vodafone help desk to solve the dropouts etc. They ended up being given a replacement router from Vodafone. That did not fix the problem.

Luckily the new router had 5GHz WiFi.

Fitted dual band dongles on their laptops and linked them to the 5GHz network.

They are very happy with stable WiFi...

My first ever AM radio network connection was with a 1MHz AM crystal(OA91) radio receiver.

It may take some time to become cheap enough to pull off but imagine if 802.11ad is as good as they say and having tiny AP's inside power sockets or network jacks which are patched will probably make the product feasible for a residential set up. And you wont have interference from the neighbours cuz the range will be low.

the idea of doing that is certainly already out there so it would be good example of where 802.11ad could be implemented well.

Wall's not a bad idea. I prefer to put a 1-4 Watt AP centrally mounted in the roof cavity for a whole house better reception. Then the xDSL routers built in AP I use for the media player on to TV in the same room on a different channel.

Sounds like you need a new high power AP.

To increase a radio's coverage area you should increase the antenna gain not increase the radio transmit power. Increasing the radio transmit power can cause asymmetric power issues resulting in increased retries and CRC errors.

edc:

Is channel 13, 14 legal in NZ?

There are two commonly used channel allocation systems in the world - ETSI (Europe) and FCC (US).

The ETSI system uses the centre channels 1, 5, 9 and 13 which has the advantage of an additional 20 MHz wide channel over the FCC system but can result in higher adjacent channel interference due to the increased channel overlap.

The FCC system uses the centre channel 1, 6 and 13. With the transmit powers utilised in most deployments there should be no channel overlap but the tradeoff is that there are only three 20 MHz channels available.

As a general rule the FCC system is used in New Zealand.

richms:

You may find that it has forced 40MHz off when you went to ch 13, which is why it is working so much better.

A standards based wireless device with disable 40 MHz channels in the 2.4 GHz spectrum when it detects the 40 MHz Intolerant bit set in an association request from a wireless client. The association request may be for a neighbouring wireless network or your own. The 40 MHz Intolerant bit is set in association requests when this option is enabled in the wireless driver.

I'm well aware of this - it was a joke aimed at richms who's also well aware of WiFi related issues.
