Medium Long Range OSP setup - HW & Performance

Hello,

I have been asked to consider the situation mentioned below.

A typical situation of a client, with a house out of town, who wishes to connect to the town studio.

Conditions :

The client's hill residence ~20 Km from the client's studio in a nearby town.

Aim/Request :

1. Obtain a decent Internet connection for the house, which does not have DSL, using the Office connection as a gateway.

2. Enable an Office VPN and eventually make use of a mini Video Conference system while at home

One would wish to propose a solution which can cover a distance of around 20+ Km with a good signal (all supposing there are no other problems such as interference, obstacles, winter weather etc) and offer a final throughput of at least 2 Mbs.

It would be could nice to be able to guarantee a minimum throughput but in similar conditions this will probably out of the question.

The main problem here will be the LOS.

It is highly improbable that there will be a perfectly direct line between the Antennae thus implicating the consideration of using a repeater somewhere on the route. (Any suggestions here, HW, typical elevation difficulties?)

Comments, suggestions or links regarding this type of task, difficulties encountered and the performance obtainable in similar conditions would be most appreciated.

If there were any tables mentioning the components used with their tech specs in recently successful comparable setups this would be very useful.

I have noted that the Aironet Wireless Bridge Series, such as the 1400, seems promising, however since this alone would not be sufficient; ie The high gain antennas (eg: AIR-ANT3338/AIR-ANT58G28SDA-N Types) and the secure installation add significantly to the cost, I need to find a solution that is reasonably priced, otherwise the overall cost might well overcome the use advantage.

Many thanks for any support.

Cisco Aironet Bridges would be the ideal choice in this scenario. Cisco 1400 Bridge would be the best for this. As you said for such long range communications to happen without any interference and line of sight issues, high gain and appropriate antennas should be used. You will find all the information that are necessary to choose the right antenna at this URL.

Hi Pengke11,

Thanks for reply. I realise that this type of theme has been discussed on several occasions in the past, however there are a few considerations which I have not found mentioned with detailed explanations.

I had already visited the link you offer and read about the Antennae - mentioned in my post.

There is a question of limiting the power/EIRP budget in Europe-ETSI. Apart from this there is the problem of the location of the Antennae (height) and the LOS. A complete solution, for a semi private venture, could be difficult, cost prohibitive or both.

I was wondering if the people here have any links to successfully managed similar projects and the problems encountered and how they were affronted. [Not 'Access Provider' projects but private projects, as stated before.]

Thank you for any comments
