Looking for a Wireless Bridge Solution

We have just bought a second office building 2 kilometers away. We would like to setup a wireless P2P connectivity between both as the leased line option is coming out to be quite expensive.

The best solution that we have found so far is Motorola PTP300 Bridge (25MBps Kit - 5.4 or 5.8GHz frequency kits) but it an expensive option. It is better than paying an ongoing charge for a leased line but I am just wondering if anyone knows of any better options?

Many thanks,

Nick

2 km is not a big distance. You could use any commercial wifi bridge with directional antennas, if you have a clear line-of-sight.

Thanks Tamas

In our case clear line-of-sight (image attached) can be easily achieved by installing the antennas at some height but its the equipment that I need help with. Would you have any recommendations as I have no knowledge of the PTP bridges?

If you want it cheap, even a TP-Link WA5110G (plus external antenna) would be enough. If you want brand, the Cisco Aironet 1300 series is for this exact purpose.

For the TP-Link, an antenna like this would be okay:

Also, since it's an external antenna, a lightning arrestor never hurts. Something like this:

Make sure the connector types (RP-TNC or RP-SMA) matches on the equipment you buy.

TimotiSt,

I don't see TP-Link is a P2P(As per your link).Moreover, author's choice is 5.4GHz or 5.8GHz. wheres TP-Link is 2.4GHz

I'd assume the author's choice is connectivity, not frequency band... But you are right.

The mentioned TP-Link model works perfectly as a P2P (even P2MP) bridge, but it was just an example. Most decent APs can do it.

Go with 5GHz as it's less likely to suffer from interference.

Use something like this...
