We have a requirement to connect a number of notebooks in a building to a
ship - wirelessly.

The current proposal is to have a wireless bridge on the ship, bridging to a
bridge on the ground. This bridge on the ground is then connected to an
access point by cable and the notebooks connect to the access point.

The access point maybe required to be a distance from the bridge due to the
structure of the buildings - so that the access point can definately connect
to the notebooks.

I am not sure this is the best way. I don't want to run a cable from the
bridge to the access point. I looked before at a repeater inline - with only
using access points - but the signal was slightly un-reliable and we cannot
afford this network connection to be unreliable.

Any thoughts appreciated.

You need to be a lot more specific about distance, obstacles between
the ship and the building and define the actual number of
simultaneous wireless users.

Can't be that specific as it is not going to be tied to one building.

The laptops (six devices) will be anything up to 150 metres from the ship,
with various obsticles inbetween eg walls, metal doors etc.

That's why I am asking about repeaters etc.

Hi
Technically you do it as describe in this page.
Wireless Bridging - http://www.ezlan.net/bridging.html
Would it work?
It depends on the environment and the capacity to install multiple
Bridges/Repeaters.

We are did the same in our outdoor wireless using Cisco 1310 bridge. Based
on our experience, you must have very clean distance between bridge and
bridge/repeater/AP. More repeaters, the single will be weaker and
un-reliable.

You might need wired access points for roaming and/or wireless
repeaters coupled with one or more devices on the ship (you didn't
say how big the ship is). Or even a combination of everything,
depending on topology. Special antennae might help as well. If you
have the capability to hardwire some access points at the edges of
buildings, that would help, especially with walls and metal doors in
the line of sight.
