Crossing the Great Divide with PTP Links

By Ray Savich   May 26, 2016

As the current record holder for the longest wireless network link in the world, Cambium Networks is serious about connecting places that once seemed distant from each other. With our point-to-point (PTP) links, there is no rift too far to cross.

What you might not know is that these links can even work across completely inhospitable divides where RF performance is particularly challenging. Gorges, crevasses, craters, seas – the world’s great chasms.

Today, I’d like to showcase some of the great work that the Cambium team is doing to bridge the gap across these divides around the world. Here are some of my favorite examples:

Andaman and Nicobar Islands

There are hundreds of islands in the Bay of Bengal, but until recently, there was no network connecting the two most populated ones. There was no feasible way to run a 40 kilometer-long undersea cable between Port Blair and Neil Island, so we stepped in to provide a wireless PTP 650 link. Now a single radio link crossing the Bay of Bengal has been established for the first time in history.

For a full case study on this endeavor, see here.


The Ngorongoro Conservation Area in Tanzania covers 8,000 square kilometers of dense natural beauty. But the 500,000 yearly visitors to this region still wanted Internet access, and the Ngorongoro Conservation Authority needed a reliable video surveillance system to catch wildlife poachers in their tracks.

Trenching wires through this pristine landscape would not only be unsightly, it would be far too expensive. And previous efforts using satellite communications provided weak signals that hardly worked on cloudy days.

Tasked with delivering consistent high-speed communications to this vast area (without encroaching on the region’s treasured ecology), local service provider Cybernet deployed a combination of Cambium’s point-to-point and point-to-multipoint links to connect various buildings, video cameras and more. In this network, the longest backhaul link covered a full 143 km (88 miles).

Pike’s Peak

This aforementioned record-holding link spans 245 kilometers (152 miles) between Pike’s Peak, Colorado and Cheyenne, Wyoming. To put it in perspective, that’s about the distance between Paris and Brussels. Over the past year, the connection has powered clear, high-speed communications over high-interference areas including the Denver metropolitan region. Learn more about this project here.

So, why do I care so much about expanding wireless broadband across these great distances and rugged regions?

It’s because high-speed Internet access should not be limited to wealthy, densely populated regions. It should extend just as easily to people who live in remote places far from urban centers. And if we can connect these seemingly impossible spans, just think what we can do for you. If you have a link that you are particularly proud of, you can showcase it on our Community.

Everyone, in every far-flung corner of the Earth, has the right to a wireless connection. This philosophy is what drives much of the work we do, and we look forward to pushing the boundaries of broadband even further in the years to come.
