RE: Unifi wifi AP's

[Nigel Giddings <nigel@xxxxxxxxxxxxx>]

Actually considering using 802.11a at home with some  Netgear WAG102s
(probably 4) as an overlay network for a few RaspberryPi based media
players leaving 802.11g for laptops.



Using =91n=92 isn=92t really on the roadmap as we have slow Broadband and
w=
hile
150Mbs sounds good not sure we would see the benefit=85

Yeah - doing shows and such like nowadays is an absolute nightmare ... the
venue obviously want to try to get you to use their WiFi (and often
specifically exclude you from throwing up your own wireless network) but
ca=
n
you imagine somewhere like ISE or CEDIA with a couple of hundred exhibitors
with all their kit streaming media on a single network ...

The "boss" usually just expects you to be able to throw in a self
contained
network and use that because you use it for dealer demos and of course
assumes you can use WiFi so that you don't have the hassle of wiring the
stand for Ethernet (as the stand builders generally don't understand that
yet).

WiFi really shouldn't be used by anything other than portable devices and I
mourn the passing of 802.11a which was actually a really good standard -
short range and 5GHz - and would have been a great basis for building a
nic=
e
stable, reliable managed network. :-)

Oh Yes!

Have been at conferences in the US (couple thousand geeks), where people
with MiFi's were completely trampling over the conf WiFi due to channel
conflict and broadcasting at higher power.
