Docent Corp Solutions: Indoor Positioning System

What does an IPS (Indoor Positioning System) do? People use positioning systems such as GPS on an hourly basis without realizing it. However, GPS doesn’t work inside a building and does not provide enough accuracy to be useful in indoor venues where things are very close to each other. Indoor Location Based Services will help customers find products and services quickly and easily.
In an indoor setting, high accuracy is the key. An Indoor Positioning System must provide much greater accuracy compared to GPS, which is used over long distances or areas.


A General Rule of Thumb

In order to implement a positioning system, you must have several reference points with a known location or a known path of movement. In the case of GPS, there are satellites with a known trajectory orbiting the earth. For indoor locations, you need to have some kind of device installed in the building that provides reference points (the exception is photographic positioning, which mimics the complex processes of the human brain). There is no way you can know your position without reference points. Most IPS’s use devices that utilize radio frequency signals at a fixed location to provide your position on a map.


Alternative Methods

Photographic methods mimicking the human brain are very expensive and require knowledge of the landscape. They require a large database of images. Maintaining the system is also expensive. You basically need to photograph every single corner of your building periodically. It will never work in locations such as parking lots where the landscape changes very frequently.
Positioning someone on a particular floor is a major challenge for most IPS’s. This is mainly due to the big margin of error of radio frequency based IPS’s. However, IPS’s that use non-radio frequency methods are very expensive to implement and maintain.


Docent’s IPS

Low Cost and High Accuracy
Our basic devices cost as low as $60 per 2,000 sqm (20,000 sqft). Once installed, they can last up to 20 years without maintenance.
Our basic IPS utilizes a set of unique algorithms that will give you 1 to 3 meter (3 to 10 ft.) accuracy to make sure it positions you at the right spot and more importantly on the right floor. IPS’s with a higher margin of error of 3 meters can position you on the wrong floor.
We try our best to make our hardware as low cost as possible. It’s our intelligent software that provides greater value, not expensive hardware with super-fast processors and exotic parts that are not needed for most situations.

Flexibility
We are a platform provider run by resident and non-resident scientists and engineers. Therefore, we can provide different levels of IPS technologies depending on your needs and budget.
One of our patented IPS’s provides accuracy up to 15 centimeters (6 in.). Our basic nodes, which have 1 to 3 meter (3 to 10 ft.) accuracy depending on the complexity of the space, utilize regular smartphone protocols. However, some of our systems with very high accuracy require a special receiver.
Our IPS uses a proprietary algorithm that yields highly stable and highly accurate positions of your customers’ phones or our tags.
We also can customize the IPS to suit your accuracy needs. Contact us to find out which IPS is the most suitable for your organization.

Grocery Shopping In The Time Of A Pandemic

Image
If your retail business has managed to stay safe and afloat during the rough ride of coronavirus – congratulations. Many haven’t been so lucky. As of November 2020, the United Food and Commercial Workers International Union (UFCW) — a labor union comprised of 1.3 million members — reported that over 17,400 grocery workers have now been infected or exposed to  Covid-19. Grocery shopping, once an ordinary chore, has become a hazardous outing and one many avoid for fear of infection.   What Scientists (& Legislators) Are Saying Coronavirus is an airborne virus, so it’s not exactly mind-blowing news that essential workers are especially vulnerable. Tight indoor spaces, like those found in grocery stores, allow viruses to linger and infect those nearby. The EPA even claims that indoor infections can occur beyond the previously reported 6-foot range. Of course, research suggests that minimizing the number of people in an indoor space can reduce the spread of Covid-19. And some le

Why Do We Need to Count Footfall Traffic?

  Why Do We Need to Count Footfall Traffic?   If you own a retail establishment or manage a shop at a mall, you’ve probably heard of the term “footfall traffic”. F ootfall traffic is the measurement of people entering a shop or shopping mall. Footfall traffic is far more important than simply knowing how many people are entering your shop; it’s taking that information and using it to make important marketing decisions that will impact the number of consumers converted into sales. Keep in mind that large numbers of people entering a store doesn’t necessarily mean that the store will be profitable but understanding the numbers will help businesses find ways to generate profits. Why Footfall Traffic Matters Footfall traffic matters because it can show a shop what they’re doing right and what they need to improve. For example, finding out that huge numbers of unique people are entering your shop indicates that your brand is recognizable or that the outside of your shop is attra

Beat The Pandemic with High-Tech Solutions

Image
  Has your business been hit hard by coronavirus? If the answer is yes, you’re far from alone. Physical stores across the globe have been forced to shut down with no signs of re-opening and minimal relief. Not to mention, consumers are on tight budgets and e-commerce has never felt easier. This newfound fear of being outdoors and standing (and shopping) among large crowds has warranted a new word – coronaphobia. And it’s impacting bottom lines everywhere. However, there’s one silver lining. Most grocers and supermarkets have managed to hold on in a post-pandemic universe. There’s just one caveat. Continued growth is dependent on new strategies, business models, and high-tech tools designed for in-store use. To combat the inevitable decline of in-store businesses, Docent Corp, the developer of a high-precision Indoor Positioning System (IPS) , aims to use its patented technology to bring the grocery business back to life and keep it alive indefinitely. How IPS Works Utilizing
