Allow me to introduce myself...

My name is Sascha Reuter and I'm working as an network engineer. Among 
other infrastructural things I'm responsible for the high-available 
enterprise WLAN infrastructure with more then 200 accesspoints providing 
wireless coverage for thousands of square meters.

The point of my post is the following...

Call me a chaos theorist, but from my experience (you guys ever visited 
the chaos communication congress in the last years? ;-)) I would say we 
will get into some real problems providing the wireless infrastructure 
with random SOHO Routers which will make the wan-connection (at least 
over the air) unusable. I don't know much about the location. How many 
m² do we have to cover with wireless access? How many clients do we 
expect?! (I would say an average of 1 per person). SOHO Routers are very 
limited in the amount of clients they can hold at one time.

We have a _shared_ bandwidth of theoretically 54mbit/s, which means 
about 2,2mbytes/s in real life situations ( 
http://en.wikipedia.org/wiki/Real_Life )
Internal transfers (I know you guys like to share the stuff you "own" 
;-)) will slowdown the hole wireless network. Because we do not have an 
enterprise
solution over there where we could switch each client in a seperate 
private vlan, i would recommend to bring your crosscables and/or 
switches for these kind
of "experiences"..  to don't f*ck up the network... Otherwise it's not 
the network to blame, it's you! :-p

Because we can't use WDS in this dimension of clients (it would cut the 
bandwidth by half on every accesspoint we add) and we have no wired 
infrastructure (have we??) between the access points we don't have a 
really good way to connect these, do we? [fill in your suggestions here]

On the other side... ( the wan side )...

We have this very nice dedicated line of 22mbit/s which would serve 
everybody's home requierements (and I really appreaciate it that 
Claudio organized this bandwidth for us in 2228m height!), but... I hope 
the WAN Router supports some good/flexible QoS/bandwith-limitation 
features so everybody gets a piece of the cake. (this cake is _no_ lie, 
you portal(tm) playing guys!).

Maybe I'm just thinking too far/large and we just have a few people 
sitting in two rooms using the access to the internet... :-)

I'll bring no hardware with me ( because I don't wanna explain the
airport security staff for what all these cables are looking out of my 
luggage. :-) ) but will always like to offer my help/knowledge to make
the best out of what we got...

See you on (t3)board!

Cheers,

Sascha
