90km Wireless link

[TomLima]

Hi there,

 

Ive seen some LTT videos about PTP links recently.

 

Wi-Fi (or Wireless, duh) links can be very efficient and reliable even on a long distance.

 

Here's an example of a 90km PTP link with Carrier Grade SIAE radios, and a 2,40m antenna. (Also one of the towers are @ my profile pic!)

 

Link Speed is currently between 1.4Gbps-1.5Gbps, Link Mode 2x 2+0 XPIC (quad chain IDU)

 

IDU overview and tower locations in attachments, for science! haha.

 

Keep in mind those radios provide internet to a whole city. We're a ISP.

Nice

That's sexeriffic!

I have a picture of some logistics of a smaller antenna (not that small but...) and aswell a picture of the IDU (which controls the radios mounted on the antenna)

 

Notice the 4 chains (the black cables) in the IDU. Those cables goes all the way up to the radios.

Awesome! Here in Minas Gerais, Brazil, something like that would be harder. Like @LinusTech said in the first long range WiFi video, geography is a bitch.

I think there's huge differences between setting up for regular usage and ISP. Specially in frequency.

latency?

Solid 1ms.

ISPs usually licenses the frequency to prevent noise.

This looks like a serious microwave link. Thanks for showing this off!

The CCR is set up for tunnelling over the link?

Nice! Siae seem to make some nice stuff, though I hated their web UIs. A colleague of mine maintains if someone can make great DMRs with good web stacks would instantly have us as a customer! Our largest dishes were 1.8M and I thought those were huge!

Thanks for sharing, its really interesting hearing what proper high-end installations are capable of.

Do you only work in Goiás?
