bridge between 2 buildings

hi,

I need an advice for a bridge solution. 2 buildings, 150meters between them. What cisco equipment to use for this case. I'm a beginer in wireless. I really need your help

Re: bridge between 2 buildings

First, keep in mind that making a recommendation without being able to do a site survey, knowing the budget, seeing where you have access (window to window? rooftop to rooftop?), or knowing what the bandwidth requirements and size of the LAN on either side would be tricky, at best.

ASSUMING that you have good line-of-sight, access, and reasonable bandwidth needs, check out htese application guides for the 1300 and 1400 series outdoor bridges:

It may also be possible and / or desirable to use a 1200 series in a bridging role with the appropriate antenna.

Generally speaking, 150 meters is not a problem. You must have clear line of sight, plus some distance to accommodate the Fresnal Zone. The application guides I linked to include a calculation tool to determine if you have enough space to handle a true clear path.

One of the primary differences between the 1300 and 1400 bridges is the band (2.4G vs, 5G). IF you have a lot of activity in the 2.4, then you may want to go with the 1400 - there isn't as much traffic in the 5G band. As part of your site survey, you'll wnat to scan the bands to see what the level of traffic & intereference is for your area.

Give the App guides a look and let us know what other questions you have. If you are new to this, it might be better to refer the planning & inplementation to an experienced contractor. There a lot of gotchas .... ranging from "This will keep the system from working" to "This is danerous and can get someone killed or seriously injured."

Also keep in mind that there are usually local electrical codes that must be followed (safety & grounding) and federal regulations that must be followed (power, antenna implementation).

A professional wireless contractor will know these things and build a safe, functional system that won't kill you or your network in bad weather.

Good Luck

Scott
