Cambium Mission    |    Forum    |    Blog    |    Contact


On October 28, 2011, Cambium Networks was a fledgling new company with a vision of bringing broadband to where it’s most difficult. By coincidence, America’s Broadband Heroes: Fixed Wireless Broadband Providers was published by WISPA (Wireless Internet Service Providers Association) just a few weeks prior. Recognizing as the white paper states that “fixed wireless operators are doing the heavy lifting in rural areas,” we set out to make it simple and economical to become a wireless Internet service provider (WISP) in areas that lacked adequate connectivity, and also educate traditional wireline operators on how they can more quickly grow their coverage areas.HappyBday3.jpg

Today on our third birthday, we are proud to have delivered on this through our completely refreshed and update solutions portfolio that feed into our company mission of Connecting the Unconnected. In 2014 alone, we’ve upgraded and made improvements to all our platforms, including five additions to our one-year-old ePMPTM solution, and numerous software updates, in addition to an update to our industry-leading LINKPlanner tool for point-to-point and multipoint path planning. We’ve made tremendous headway in developing a true end-to-end portfolio, as evidenced by the variety of end users our products support. Every day, thousands of networks built with Cambium equipment connect schools, hospitals, oil rigs, governmental agencies, businesses and homes in more than 150 countries. We are present in rural and urban areas and developed and developing communities. Through our installations, we have proven that fixed wireless broadband is not just an alternative to the “traditional” way of doing things – it goes hand-in-hand with other technologies in proliferating high-quality connectivity.

The milestones we’ve met and surpassed over the last three years are numerous. With over 4.5 million units deployed, the stories that come to us from our customers let us know that we’re making a difference every day in people’s communities:

As we embark our fourth year, we will continue to innovate and lead in outdoor broadband, and build into new areas to broaden our portfolio. The coming year will be our most transformative yet, and we look forward to sharing our progress here. If you use our products and have any case stories or suggestions for us, please let us know on our forum where you can meet our engineers and chat with other network operators from the many verticals we support, or on our social networks: Facebook, Instagram, Twitter, LinkedIn and Google+.

Making a difference is what makes our team get up every day, and we look forward to working with you in the years to come.

Much as people want them, silver bullets are hard to come by – long gone are the days when a single solution can solve for any connectivity situation or need.

In the wireless broadband industry, this is especially the case for point-to-point (PTP) solutions which can backhaul both IP and legacy TDM traffic today, but be future-proof and scale to handle tomorrow’s high-volume IP traffic. The reality is that there are many different PTP applications – wireless ISP (WISP) backhaul, small-cell backhaul, video surveillance, public safety backhaul, enterprise access and campus connectivity using private networks – all of which have different requirements.


Today, Cambium Networks is introducing the PTP 820 point-to-point licensed microwave backhaul platform to our PTP portfolio with three distinct modules designed to meet those varied demands: PTP 820S, PTP 820C and PTP 820G. PTP 820 can be deployed in all-outdoor, split-mount and all-indoor configurations, and supports all types of networks requiring either hybrid or all-IP traffic.

PTP 820S and PTP 820C are all-outdoor radios, well-suited to the all-IP traffic needs of WISPs, enterprise access and campus networks. PTP 820S is a single core radio capable of 1Gbps throughput which provides the lowest entry cost for the network edge. PTP 820C has dual-core functionality, enabling the system to be deployed up to 1Gbps day 1, with scalability of up to 2Gbps day 2 via a software upgrade to enable the second radio core. This eliminates the need for expensive manual intervention on the tower when more capacity is needed in the core network.

With options for both native Ethernet and TDM traffic, the flexibility of PTP 820G makes it ideal for public safety, utility, railroad, transport and government private networks. With both split-mount and all-indoor options, PTP 820G provides a solution for the most challenging network availability requirements.

With its breadth of capabilities, PTP 820 will solve the specific connectivity challenges you are facing and provide you the scalability and flexibility you need for the job. Plug in your own specs into LINKPlanner, our free tool for designing and configuring PTP links.

It's often easy to see the results of the work of a knowledgeable expert. In any field of work, the finished product performs well, and the design is clean with little or no wasted effort. Wireless networks are no different. When a network is designed and installed by an expert, hardware and software performance is maximized, and installations are clean, safe and secure. Failures are rare, and the overall effect is a network tailored specifically to the needs of the end users. Customers quickly grow to trust the network and the service provider, because like a fine piece of machinery it is always ready and available for them.

No one is born with the expertise to build a finely tuned network. Experience and up to date product knowledge has to be acquired, and our technical training program makes it easy. In our technical certification classes, technicians get in depth planning, design, and operational theory, as well as hands on experience with the latest hardware and software on ePMP, PTP 650 and PMP 450. Many service provider technicians in our classes are building networks for the first time, and our classes certainly enable them to be successful. Even more insightful is the information that technicians share with each other based on their real world experience. When teaching these sessions, we go deep into the details to show exactly how to optimize performance, and we often hear "I didn't know it could do that." Most satisfying for me as an instructor are those "A-Ha" moments when a technician will see the solution to solving an important customer's technical issue, implement the change during a break, and see immediate results.

We make it easy for all students to gain this high level of expertise. We suitcase our equipment and technical trainers travel around the world to make it convenient. Check out the training schedule here

Technical expertise makes the difference between installing equipment and enabling long term customer satisfaction, and it's available today.

While collecting personal fitness data and social “likes” is fueling our well-documented data explosion, other streams of non-stop data creation are working harder for humanity. These bytes are collected to measure how to continuously improve and hence sustain more efficient, comfortable and safer cities, an enticing goal fueling the global smart cities services and infrastructure market projected to reach $1,266.58 billion by 2019. 

This data collection can happen efficiently and cost effectively because of wireless broadband. Cambium Networks is well-versed and experienced in the ways in which wireless broadband can be applied in building the smart city of the future. Here are a few examples of the work we’ve done in this realm:blog - Smart Cities.jpg

1. Smart Traffic Safety and Management: Every driver or pedestrian’s nightmare is getting into an accident not being able to get help. Through cameras installed along highways or at intersections that are backhauled to a law enforcement agency, videos of accidents can be viewed by the police in real time to they can respond accordingly. 

On a more routine level, wireless broadband can also work to manage traffic congestion, controlling traffic signals and traffic flow in real time, as a PTP 600 network does in the U.K. for its national motorway networks. 

2. Smart Security: For The Housing Authority of the City of Los Angeles, hiring security guards to monitor every building in its largest housing projects was well out of its budget. A cost-effective solution was installing a Cambium Networks point-to-point video surveillance solution that backhauls video footage from cameras installed in stairwells, hallways and other hidden corners so residents feel safer and criminals can be caught on film, any hour of the day. 

3. Smart Energy Supply: There are multiple applications of wireless broadband that assist with efficient energy distribution. For its smart grid communications infrastructure, Oklahoma Gas & Electric is using a combination of PTP 600 and PMP 320 wireless broadband modules. SCADA, or supervisory control and data acquisition, is another key wireless application that allows network managers to remotely monitor reservoirs and wells situated far from the community they serve. San Diego is using PTP 600 and PTP 800 for its water department to this end. 

This is just a taste of what’s possible with wireless broadband. With the ability to measure what city governments and agencies seek to improve upon, new efficiencies and a greater level of comfort and safety can be achieved for city dwellers and those passing through. If you have a smart-city application of Cambium Networks technology to share, please email [email protected].


This article is abridged from Making Cities Smarter through Wireless Broadband, which ran in Future Cities on August 27, 2014.

John Lennon said “Life is what happens when you’re busy making other plans,” but what if things in your network performed exactly the way you planned? Of course, you'd save time and money avoiding expensive rework. Even more meaningful, you would have the satisfaction of knowing things were done right the first time.

Planning a wireless broadband link is that way for network operators who use the LINKPlanner software tool. This free software takes the source and destination location and provides an estimate of the link performance. If you're not familiar with LINKPlanner, check out the case studies on Hackensack UMC, Brockton Housing Authority and Z-Net.

What’s new is that this powerful tool is now able to plan links for Point to Multipoint PMP 450 and ePMP access networks. To test it out, one network operator in North America put in the coordinates of his PMP 450 AP and associated Subscriber Modules. He wanted to compare the LINKPlanner modeling tool predictions against actual field data. You can see his screen shot here. His summary comment:

“After all this chitter chatter about it, I spent some time with it today. The predicted signal levels match actual subscribers almost spot on. When you export back to Google Earth it will draw your sectors on the map as a shaded arc and it will draw lines to the SM's showing the fresnel zones and such. This screenshot is at a weird angle to keep my subscriber's names out of the view, but you get the idea. The red line coming off the tower is an install that honestly wouldn't have worked on the AP's shown in the image.”

Check out the LINKPlanner software…it’s free, and it will save you time and money. Also, let us know your experience and share improvement suggestions. Your ideas help us plan improvements for the planning tool.
