Is 5GHz better than 2.4GHz for wireless

I've experienced lots of problems with wireless using the normal 2.4 GHz
does anyone have experience of the 5GHz hardware? As taken for the Solwise
web site below?

Operating at the 5GHz radio bands has several advantages over the more
common 2.4GHz band:

Better penetration

Better scatter

No abnormal adsorbtion by water or damp

Larger number of non-overlapping channels which means less radio congestion

OFDM over the whole speed range (better for non line of site operation)

I use a wgu624 from netgear (Its a cr@p router but thats not relevant).

The 802.11a gives me a higher throughput to my laptop when I am close to the
router.
Its range is significantly less than the 802.11g.

This may be because I swapped an Intel 802.11g card for an Intel 802.11a/g
card in my Toshiba laptop so I don't have a matching aerial.

From my understanding, the higher the frequency the lower the range... The
case if you look at 900 or 1800Mhz mobile phone networks.

Ermm what?

Yes of course it will. Its a higher frequency.

Bollox. This is back to the (very) old bollox about 2.4GHz being some
sort of mystical absorption/resonance frequency of water. Its TOTAL
CRAP. Not at all surprised that Solwise keep peddling this nonsense
though.

>Larger number of non-overlapping channels which means less radio congestion

For now

Main advantage is that less use is made of the 5GHz band. You won't
get any further than at 2.4GHz (assuming the same ERP) but you may get
better data transfer rates due to less interference.

So back to my other plan to look at homeplug systems - Devolo and Solwise?

If you just want a bit of extra range then..

buy two 802.11g USB sticks.
Buy some foil backed card..
Cut a couple of 150mm x 600mm strips from the card.
Bend them to a parabola shape and stick a USB stick at the focal point.
Point them at each other.

Don't expect miracles you will only get a few hundred feet using a pair.
You will get less with just one and an omni aerial on the router.

got a photo of this?

Photos? I know where photos are for something 'similar' to this...

I rather liked this one http://www.usbwifi.orcon.net.nz/brmwifi.jpg
and it's the sort of design someone on an island might want to try
(so long as there's a lot more weatherproofing :-)
