From traditional compasses to smartphone GPSs, we have seen a huge transformation in indoor positioning technology. Location tracking has become such a ubiquitous term that it’s almost impossible to imagine our lives without it. Outdoor navigation using GPS technology is an essential part of our daily lives.
As useful as GPSs are for outdoor tracking they have traditionally failed to work inside. That necessitates the need for indoor location technology or indoor GPS which guides you when searching for indoor spaces. But, before we jump into indoor positioning technologies, it’s important to see how these indoor technologies have evolved over the ages.
The first “compass” dates back between 300-200 B.C China, during the Han Dynasty and Tang Dynasty.
While using ladles made of lodestones in their fortune-telling rituals, the Chinese noticed its unique ability to always point North-South. What seemed to be some sort of mysterious property turned out to be the lodestone’s natural magnetic field. Because of the lodestone’s directional predictability, the Chinese have been credited as the developer of the first compass. This first compass was a square-shaped slab with cardinal points and constellations marked all over it and honestly was not intended to be used as a navigation system. Rather, it was intended to be used in fortune-telling by means of geomancy and feng shui.
By the 11th century, the use of the compass as a navigational technique had gained popularity among sailors, voyagers, etc. The compass is known as China’s gift to the West.

How Indoor Positioning Technology Works
While the compass is known as China’s gift to the West, Mapsted has gifted the most accurate indoor navigation technology to the world. Indoor positioning technologies are very different from global positioning systems.
Indoor navigation is a term used to describe wayfinding within a building through the use of an IPS (indoor positioning system). An IPS is a network of devices used to locate or help people navigate precisely inside buildings such as airports, parking garages, underground locations, schools, hospitals, resorts, and shopping malls. There are many different methods, techniques, and devices, such as Bluetooth beacon indoor positioning technology and Acoustic indoor positioning system technology that are used to provide indoor navigation; all of which revolve around mobile devices. Technology such as Wi-Fi, Bluetooth, digital cameras, and clocks are all found within smartphones today and can help relay information to beacons that are strategically placed throughout a defined geographic area.
The term “indoor positioning technology” is broad and can be implemented in almost every industry whether it be commercial, military, retail, or inventory tracking industries. While there are many commercial systems on the market, there are no standard indoor navigation platforms (yet). Instead, the installation of an indoor navigation platform is designed specifically to the customer’s spatial dimensions, accuracy needs, and budget limitations.
IPSs rely on the use of different indoor technologies, including distance measurement to nearby anchors with fixed positions (e.g, Wi-Fi routers or Bluetooth beacons), magnetic positioning, and dead reckoning. They either actively locate a mobile device or provide ambient location or environmental context for an iOS or Android device to get sensed.
Current Approaches to Indoor Positioning Technology
Prior to Mapsted, there were 5 main approaches to detecting indoor location information: GPS/ cellular technology, Bluetooth beacon indoor positioning technology, geomagnetic technology, UWB indoor positioning system technology, and inertial navigation technology.
GPS/ cellular technology simply doesn’t work. Walls and similar obstacles interfere with the signal between satellites and mobile devices. While a 30-meter mistake is relatively okay for Google maps outdoors, 30 meters indoors could be the difference between walking into the store you actually want to go into or not.
Bluetooth beacon indoor positioning technology needs to be placed at numerous positions inside to cover the entire facility. Yes, beacons are precise, but customers must have their Bluetooth enabled or be connected to Wi-Fi within 100-150 meters. Scaling beacons is hard because their batteries must frequently be replaced, and their accuracy gradually diminishes.
Geomagnetic technology is affected by indoor magnetic disturbances. Environmental changes such as renovations, hospital machinery, kiosk placement, or furniture rearranging can interfere with accuracy.
Ultra-wideband (UWB) is interesting. Three or more ultra wide-band readers transmit a very wide pulse over a GHz of spectrum. The readers then listen for chirps from ultra wide-band tags. These tags have a spark-gap-style exciter that generates a little pulse within them, which creates a short, coded, very wide, nearly instant burst. The readers then report very accurate time measurements from the tags back to a central server. Because the UWB signal is extremely wide, the accuracy of the location information is relatively good. However, UWB indoor positioning system technology is the most expensive system to install. Even though UWB tags are inexpensive, every location has to have at least three readers because of the limited range of the tags. These readers are very expensive.
Inertial navigation technology can cause problems just from daily cell phone use. Phone swinging, change in orientation, or simply not walking in a straight line can affect the accuracy.
Indoor Positioning Technology in Action
By far, beacon-based indoor positioning technologies have been the most popular indoor navigation technology. In theory, Bluetooth beacon indoor positioning technology should allow for smart and highly detailed data collection.
Forbes wrote that beacons would be “especially useful in places (like inside a shopping mall) where GPS location data may not be reliably available” and also said that, “BLE [Bluetooth Low Energy] allows for interactions as far away as 160 feet” with greater sensitivity than GPS or Wi-Fi tracking methods. This should mean owners get the same detailed insights into their in-store activity as they do on their app or website.
A good beacon network should allow you to track how customers move throughout each store. You should be able to see all their patterns in detail, aisle by aisle. Then with this data, you should be able to optimize the layout of every store, understand what is working about your in-store experience, and take the small information gathered to make big improvements to your customer personalization and targeting.
In actuality, traditional location-based services are one-dimensional. Meaning that when mobile users use beacon-based indoor positioning technology, they only receive GPS services- nothing more, nothing less.
Mapsted’s hardware-free indoor positioning technology is new, cost-effective, and innovative. This technology allows users to navigate indoors without the technical limitations experienced by other solutions such as WiFi or Beacons. Mapsted is the leading provider of hardware-free indoor location tracking technology. They have developed an advanced algorithm that uses a unique combination of sources to accurately pinpoint a person’s location in any indoor venue. Since this technology is hardware-free, users can navigate through traditional dead zones, such as tunnels, using only their smartphones, and still expect 1-3 meter accuracy.
Unlike traditional one-dimensional location-based services, Mapsted is divided into 3 distinct segments that ensure everyone’s indoor positioning technology needs are met.
I) Under the Location Positioning Technology division, Mapsted offers a suite of products that deliver seamless outdoor-indoor navigation without the need for beacons, Wi-Fi, or additional external hardware.

Frequently Asked Questions
Q1. What exactly is indoor data?
Ans. Any activity on your smartphone generates data, and simply changing its position generates data, which is typically the smartphone’s location within an indoor area.
Q2. What is the most effective indoor positioning technology?
Ans. Today, a variety of indoor positioning technologies are in use. Ultra-wideband (UWB), Geomagnetic, WiFi, Bluetooth Beacons (BLE), and Radio-Frequency ID (RFID) are some of the best.
Q3. How does indoor positioning operate?
Ans. To achieve room-level accuracy, tags that emit signals in pulses and receiver devices that pick up signal transmissions are required. The data would then be measured for real-time positioning using time of arrival, angle of arrival, and other methods.
Q4. What exactly is blue dot navigation?
Ans. Blue-dot navigation is a well-known type of navigation. Most of us have used Google Maps, which displays our current location as a visible dot and a path if we enter a destination. This is the best example of Blue-dot navigation in the wild. Similarly, an indoor version is available through Mapsted.
Q5. Can GNSS be used indoors?
Ans. While GPS is the gold standard for outdoor navigation, it is ineffective indoors due to poor accuracy and the inability of signals to penetrate large obstacles. This is the reason why GNSS isn’t popular for indoor navigation or positioning. However, Google is offering GNSS-based indoor navigation without leaving the Google Maps app.
