Connecting Wireless Network from Building to BuildingWe 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.

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. Show quoteHide quote "Barb Bowman" <barb@nospam.com> wrote in message news:pv3cg39geld1vh17jducn12eeqm8v2md71@4ax.com... > 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. > > On Fri, 5 Oct 2007 09:52:01 +0100, "Jim" <j**@nomail.com> wrote: > >>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.

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. Jack (MVP-Networking).

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. -- Show quoteHide quoteBob Lin, MS-MVP, MCSE & CNE Networking, Internet, Routing, VPN Troubleshooting on http://www.ChicagoTech.net How to Setup Windows, Network, VPN & Remote Access on http://www.HowToNetworking.com "Jim" <j**@nomail.com> wrote in message news:XfWdnZTlkIVTjpvanZ2dneKdnZydnZ2d@pipex.net... > 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. > > > "Barb Bowman" <barb@nospam.com> wrote in message > news:pv3cg39geld1vh17jducn12eeqm8v2md71@4ax.com... >> 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. >> >> On Fri, 5 Oct 2007 09:52:01 +0100, "Jim" <j**@nomail.com> wrote: >> >>>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.

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.
