bandwith

Are the computers wired/wireless?
What kind of Internet Service do you have in the building already?

Linksys/Cisco products are what you will use for this.  

I just need more info.

okey, is a brand new office  80 % of the pc are wired the rest are wireless
thank you a lot, do not have any service, it must be provided by a wire
thanks

You should contact verizon to get yourself set up with an internet connection first.  Then you get a few switches to connect all the machines.  Get the service first, then we will go from there.

recomended bandwith? based on your experience?
thank you a lot

Surely to make recommendations on bandwidth you need some idea of what these users will be doing ?  If for example they're all going to be streaming video then you'll need a reasonable pipe, but if we're talking general email and normal Internet browsing then anything from a 2Mbps to 10Mbps leased-line would be fine.  Of course the higher the bandwidth the better the performance.  I would avoid DSL type services though for that number of users.

normal browsing, no video streaming, some emailing, but are 90,
thanks a lot

ADSL standard service or what kind off?
thank you a lot

what you would use then?

Like I said before I would use a 2Mbps+ leased-line service or similar.  You need to make contact with some ISPs and see what services they can provide in the location.

is ADSL service, TELMEX provider, is it ok?

who, might be good then, need some advice here?

Sorry I don't know or am able to recommend ISPs in the US.  Have you tried google ?

I mean, what internet tecnology you use in this case, im refere to you guys because your experts in this field, what you could use in the case of give internet to 90 computers?
thank you
