146.68km link

175.85Km link

I just want to find out if any other WISP has setup a long link.

We did a joint Venture with Green Wireless from Johannesburg all the way back to Standerton 175.85km links with Mikrotik equipment. We are still planning a link to Newcastle.

Will keep you up to date with the testing..

is this one continuous link, ie one hop, or is it multiple hops?

the longest microwave link i have heard of is about 120-130km or summin, so just wondering

 

[acidrain]

I assume you'll be running dual nstreme on the links with dishes?

 

[Ryder_JHB]

hmmm, What hardware was used here? I'm specifically interested in exactly which radios you made use of?

 

[sawireless]

I see that wugs want to now all the info here is it is

We have 3 hops back to Standerton using 532 RouterBoard R52H cards and 31dBi antennas.

Please note that we do not have Big investors backing us like other WIPS out there, this is all out of our own pockets.

Ah, 3 hops.
See, thats not a continuous link, so that doesn't count

 

[Ryder_JHB]

R52H (350mw Radios) plus 31dBi Grids!

Smokin! ;]

nice ... but how did you buy them, given our tiny legal limit ?

I didn't! I'm merely posting a reply, stating the obvious!

 

[Wynand]

As far as I know, 1000mW is legal on 5.8, 100mW on 2.4

I might be wrong or it could have changed.

*shrug*

 

[Trybble]

1000mW EIRP on 5.4-5.7 GHz. 5.8 is 25mW EIRP. 350mW into a 31dBi grid is way above 1000mW EIRP - it's closer to 350W EIRP.

[sawireless]

R52H

2.4GHZ runs at 350mw but on 5.8GHZ runs on 100mw

 

[Trybble]

Still way over the top, even for 5.4 - 5.7GHz. 100mW into a 31dBi grid is around 100W EIRP. If you lose 3dB in the pigtail, coaxial cable and connectors you end up with 50W EIRP.

what does this kind of distance cost?

 

[protzkrog]

the title says 146.68km link and the post 175.85km ?

It's three hops in anycase, not one link. Counting all the backbone links on PTAWUG and Jawug we have more than 1000km of links.

 

[sawireless]

The Wugs link from JHB to Pretoria 58km
as i said from town to town to town we have 3 hops from JHB to Standerton 175.85Km and the ping is 2ms from Standerton to JHB.

[protzkrog]

What is the longest link between the three hops?

So long links only count when you link between towns over rural areas, not over urban areas ? mmmkay

the title says 146.68km link and the post 175.85km ? which is it ?

 

[Xarion]

that kinda distance perfectly do-able running high powered cards, donno what the big fuss is about =] and to somewhere like standerton where i am sure there is no noise - even easier. the problem is you have one link supplying the whole of standerton what happens when that link goes down

 

[daffy]

A quick little count of some of the major backbone links on Jawug, comes to about 200km.
Thats only the backbone links between our major highsites. Not the user links, which would add up to a whole lot more...
