Have you ever been amazed at how your GPS is able to accurately route you from home to grandma’s house miles away? The advent of GPS technology changed the world we live in. It enabled applications that the inventors of GPS never dreamed about. At Ciholas, we are working with Ultra-Wideband (UWB) technology to build real-time location systems (RTLS) that provide location to applications that need more precision than GPS. We believe that UWB based RTLS systems will be as transformative to indoor navigation as GPS was to outdoor navigation.

We have been involved with UWB technology for more than seven years and have watched the technology grow from early applications into the viable technology it is today. When Decawave introduced their DW1000 IC, commoditizing UWB, we knew that we would be able to leverage the chip to develop high performance RTLS systems. Our history and exposure to tracking technologies over the years provided an inherent sense for what an RTLS system built on UWB could be.

Over the years, our UWB and RTLS toolbox has grown to include a large set of distinguishing features and capabilities. The CUWB system offers a variety of different algorithms, firmware, circuits, and antennas. This toolbox, paired with our experience operating in a wide variety of industries, allows us to create unique RTLS solutions that meet the needs of our clients.

It is impossible to build a generic set of UWB equipment to satisfy the array of unique applications. The off-the-shelf CUWB system encompasses a generic set of capabilities that our clients have used primarily as a technology demonstrator. Once a potential client has had exposure to the CUWB system, with its underlying features, they will often ask us to extend the technology to fit their application.

Some clients are looking for high performance, some are interested in battery life that lasts for years, and others might be focused on ruggedness or low cost. To meet these needs, our services extend to feasibility assessments of UWB for client applications. Our engineers’ experience with UWB allows them to predict system performance under various conditions. This experience can help clients to understand the viability of the technology for their application before they make a significant investment in UWB research and development.

Ciholas’ ability to customize our technology for different applications is a unique and distinctive feature. We help clients take their applications to the next level.

Ciholas’  CUWB Technology In Action.

The first step to successfully implementing the CUWB location system is understanding the tracking area in planning anchor locations. Survey accuracy is critical to the performance of the system. Any inaccuracies in the location anchors will be realized in the output location calculations.

Another aspect to keep in mind when planning anchor locations, is the line of sight between the tracking area and the anchors. It’s important that the anchors maintain line of sight as much as possible with the tracking area to produce accurate location data. Tripods are often used as a temporary installation solution, when ceiling mounting is unavailable.

It’s important to keep line of sight visibility from the tracking area to the anchors. Turn left, turn around, turn right, turn left, turn left, turn around. The CUWB system is a complete real-time location solution for your needs.

An Interesting project we’ve done is the Museum of the Bible in Washington, D.C. This museum is four hundred and thirty thousand square feet of space that is covered by our system. It’s a very large scale, to single largest installation of UWB-tracking in North America currently. The design process for them was a complete cycle, starting for early conceptual designs, through prototyping phases, and definitely iteration back and forth with them improving the design.

There were several different stages that we went through. Early stages obviously involved a lot of software. From there we researched different ways of holding the device, whether it be a lanyard or straps. From there, we designed an enclosure for the device with the user interface in mind. The Museum opened in November of 2017, and since that time we’ve maintained a presence on site and remotely, troubleshooting any problems that might arise.

At Ciholas, we’ve developed an ultra-wideband system called CUWB.

This system is now being licensed by companies all over the world in their particular applications, from medical, to livestock, to forklifts, to tracking athletes, to tracking drones, and so forth.

When a tag is being located by anchors, line-of-sight is required to use the over-the-air timing information between the radios.

If a human body for instance, gets in the way, our system is capable of identifying the problem and weighting that information out of the location calculations to ensure accuracy.

Ciholas’ Ultra-wideband system is superior in a few ways in that the amount of locations per second that we can get is much higher than some of the competing sources.
