What Technology is Best for Accurate Indoor Navigation?
Over time, advancements in indoor navigation technology have been significant, moving from basic systems to advanced options that can determine an individual's location within a few meters. I have personal familiarity with the development and wide range of solutions available today, having worked extensively in the tech business and with navigation systems. I'll provide my thoughts on the top technologies for precise indoor navigation.
The Evolution of Indoor Navigation
The Global Positioning System, or GPS, is frequently the first thing that springs to mind when we think of navigation. GPS performs remarkably well outside, but when we enter a building, it becomes much less useful. Many indoor navigation technologies have been developed due to this restriction, each has advantages and disadvantages.
Wi-Fi-Based Positioning Systems
Wi-Fi-based positioning is among the oldest techniques for indoor navigation applications. This method gathers a user's position by utilizing the signal strength from Wi-Fi access points. Based on my experience, deploying Wi-Fi-based solutions is relatively easy, considering that most buildings have Wi-Fi networks installed. But the precision varies a lot, usually in the range of 5 to 15 meters, thus it might not be adequate for applications that need exact location information.
Bluetooth Low Energy (BLE) Beacons
Because they use less power and offer better precision, BLE beacons are becoming more and more common for indoor navigation. By deploying a network of beacons throughout a building, a user's device can determine its location based on the proximity to these beacons.? BLE beacons can provide accuracy within 1 to 3 meters, based on my experience working on multiple projects involving them.This level of precision is suitable for a variety of applications, from retail to healthcare. However, since there are a lot of beacons to install and maintain, the initial setup can be expensive and time-consuming.
Sensors
Numerous proximity sensors are designed to reduce damage and prevent collisions. In order to detect changes in the electromagnetic field or return signal, proximity sensors frequently emit an electromagnetic field, primarily infrared light. The maximum distance that this sensor can detect is defined as the "nominal range." Some sensors have adjustments of the nominal range or means to report a graduated detection distance.
Since proximity sensors have fewer mechanical parts and have less physical touch with other objects, they frequently have great reliability and long working lives. In my experience, sensors work especially well in settings where other signals may be weak or blocked. Sensor-based systems' main flaw is their tendency to drift over time if they aren't periodically calibrated.
Map Engine
Effective indoor navigation requires a strong map engine. Behind the scenes of our map view, it operates a route engine and a navigation engine. The Android/iOS SDK plots the navigable zones and path points on a web interface for ease of use in navigation. Both bidirectional and unidirectional navigation should be supported by your application.
The web interface gives complete control to edit the routes and points. It also supports navigation between floors, making use of escalators and elevators. In my opinion, the quality of the map engine directly impacts the user experience, making it a critical component of any indoor navigation system. However, developing and maintaining accurate and up-to-date maps can be resource-intensive.

RFID
Radio-frequency identification is known as RFID. These are tiny electrical devices, usually with a data capacity of no more than 2,000 bytes, made up of a small chip and an antenna. Three components make up the RFID technology system. The scanning antenna is usually affixed to a platform and kept stationary, other handheld antennas are also available. These antennas identify RFID tags when they pass through the vicinity, and the chip on the tags is activated, communicating unique information.
RFID tags typically have a very long battery life because they don't require batteries. 'Passive RFID' tags don't need a power source and have an almost infinite lifespan, but 'Active RFID' tags, which can communicate over vast distances, have their own power source. According to my observations, RFID tags are inexpensive and simple to use in a variety of settings. But the read range is narrow, and for bigger areas, substantial infrastructure is required.
The Future of Indoor Navigation
With the latest innovations like LiDAR and 5G offering even more precision and new possibilities, the future of indoor navigation is intriguing. Indoor navigation systems should become more streamlined, dependable, and ingrained in our daily lives as these technologies advance.
