Hi All,

 I just want to set up  wifi technology in my company which  should cover over 30 KM, wifi strength ratio should be more( I mean wifi or network speed should be more ) , so accordingly i need instruments and their design, so please suggest me list instruments  needs to use  to set up ,best way to set up and give cost estimation also to implement this project ,

Thanks in advance :)

Thanks

Hi there - Can you elaborate on the availability of wired drops across this 30Km range? We do have mesh technology which helps you backhaul traffic over a 1-2 km range. You can have multiple such outdoor access points which can provide the required connectivity. Any map/floor plan indicating wired drop availability will help a lot.

I need to provide network 30 km surrounding area via wifi where customer can use that  network at any point which should be more effective to use ( I mean speed and performance ) , for that what kind of instruments do I need to use ?

I assume this is outdoors - so you will need AP170 which is our outdoor rated access point. In order to get the coverage you will need to mesh the APs for data backhaul. We support 2 hop mesh networks - which means you will need a wired drop spread across this 30km space. Appreciate if you can share a topology of this space and indicate places where the AP can connect to rest of the wired network.

Thanks for the response Krishna,

Actually I thought to use wireless connections for providing network to individual user , i mean i don't want to use wired technology 

I mean i can get network from any network provider , and from that point i need to distribute the data to customer according to their subscription,so suggest me some idea for this kind of setup and what are all the instruments i need to use to distribute the data across the specified area.

Thanks,
Rahul

The best is always to bring wired network to each AP. If that's not always possible, the Aerohive MESH gives you a good and flexible way of sending backhaul data via wifi. Use it carefully though, ideally for satellite locations only, as all devices behind would depend on the reliability of this one link (and it's performance).

On a campus like this I would try to get a proper fiber backbone running, connecting each building, and ideally with a redundant path. At each connection point you can then install a PoE switch (e.g. from Aerohive) and pull Cat6a cabling to each AP location. Depending on the size of each building, you might need intermediate Switches (e.g. if the cabling length exceeds 100m). If you are talking about outdoor coverage, you can also plan with the outdoor PoE injector, which also extends your cabling reach.

AP170 is good for outdoor, we have used them for several outdoor events and are currently covering several parts of a city with them. The "default" Omni-directional antennas are good for a generic 360° signal reach, but if you are looking at complete coverage you should take a look at the sector antennas. E.g. 120°. Same for MESH: Use the directional antennas to build a proper p2p (or point-2-multipoint) link.

You can also use AP350 (or AP390 if you want 802.11ac already), install them on the inside wall of a building, and then use an external antenna that you attach to the outside wall. Just be aware that you'd need one antenna for 5GHz and one for 2.4GHz. Or, if the outside link is for MESH only, you use a 5GHz antenna outside and the default omnidirectional antennas for 2.4GHz inside for client access.


Now, your instruments...

The Aerohive planning tool gives you a pretty good start. Enter the map into the system (you might want to create segments / areas), define a few basic walls, and place your Access Points.

To get an idea of how many APs you need, outdoor and indoor, you will have to do some measurements. Use a tools like Netspot or Ekahau (if you have the money), place 2 or 3 APs at strategic locations, and do your survey. You need to get a feel for each building, and also for the outside area. If you do not have any experience with wifi site surveys I'd seriously recommend you to check with an external company to do that for you!

Hope this helps...

Thanks for the reply,

 I need to set up this in outdoor ,and for secure distribution of  data what kind of instrument I need to use?

For giving higher speed  of data over a  network do I need to user any booster kind of thing?

approximately for 30 km distance and I need to give higher speed data to user, for that  how many antenna I need install?

For the complete setup what are all the instruments I need to buy or install?

can anyone list out the complete requirements?


Regards,

Rahul

Sorry, it's hard to understand what you really want to achieve.

You want to provide high-speed wireless Internet access over a distance of 30km, meaning that users are up to 30km away from the closest Access Point???

Or maybe you mean something else... can you please try to explain the intended setup a bit better? Maybe you can create a little diagram and post it here?

yeah you are correct, I need to provide high speed wireless internet access over a distance of 30KM for that only i have asked list of instruments

You may need to check with your local or national regulatory commissions, if they exist, to see if that is even legal.

Roughly, you need to bridge the 30km with a point-2-point wifi link first. You need proper directional antennas on each side, and you'd use 5GHz. More below.

Then, on the side where you want to connect clients, you either use the 2nd radio inside the same Access point, 2.4GHz, with normal omnidirectional antennas, or you extend your network with cable, switches and additional access points (for client access only).

Now, for the point-to-point link over 30km... well, good luck :-)

If it was 5km or similar I'd recommend you to try the Aerohive AP170 (Outdoor Access Point) and use this directional Antenna, one pair on each side:
http://www.aerohive.com/node/1452

Now, for 30km... I am not even sure this is possible with "normal" wifi.

A few hints:

- You need clear line of sight AND:
- You need to respect the so-called Fresnel zone, see here: http://en.wikipedia.org/wiki/Fresnel_zone
To calculate it, you can use a tool like this: http://www.wirelessconnections.net/calcs/FresnelZone.asp
- You probably want to look at special antennas, ideally like a satellite dish.
See here, for example: http://store.freenet-antennas.com.au/product_info.php?products_id=541&osCsid=b44f3d859d8a6db470d...
Also check out this discussion: http://forums.whirlpool.net.au/archive/1961541

As BJ said, you need to check out the regulations in your country as well!

And, honestly, you might want to look at something else than "standard wi-fi"... e.g. WiMax...

Well - good luck!!!

 Good Morning Guys

Thanks guys for your response ,

And one more thing,

finally I have question, if I need to establish wifi over a 3 KM radius ,I mean if possible we can get wired source data , from that point I need to distribute the data in all direction evenly with use of wifi. is it possible to do?

Then if possible what are ways we can implement, if possible give me 3 more option to pick best one.

Thanks

Rahul
