How many times has it happened to you that you’ve got lost in a place where even your GPS doesn’t work? Ring a bell? Airport, hospital, shopping complex maybe? Bang on! GPS doesn’t work inside a closed roof as the technology only works if your device is in visual contact with the GPS satellites. Thus, to eliminate this problem of navigating inside a closed roof building, Indoor Navigation technology was evolved.
Indoor navigation technology uses Bluetooth beacons, WiFi and, other prominent technologies to provide a clear navigation throughout the area where GPS just won’t work!
In this blog, we’ll discuss 4 different features of an efficient indoor navigation system.
Let’s get started..shall we?
An efficient indoor navigation system should be ACCURATE
There is no point developing a technology which doesn’t give desired results. What do the users want from a map? It should be accurate! Same logic goes with this technology. Accuracy is one of the most important performance metrics for this technology.
Different technologies used for indoor navigation and their accuracy:
WiFi: 5-15 meters
Beacons: 1-3 meters
Visible Light Communication (VLC)*: 50 centimeters
*VLC basically works with the help of special flickering lamps which gets detected by your phone’s camera or other light detector you have. This helps the navigation system to sync with your movements inside the building and provide you proper indoor navigation.
Indoor navigation should be highly RESPONSIVE
The map should be fast enough to respond to your queries. A mobile app is only good if it is responding to the user’s queries as soon and as accurate as possible. The users will get frustrated if the navigation takes time to respond.
It is a fast tracked world we are living in. While navigating us through the buildings, the system should always be up and ready to offer any help which might be required to the users. Real time synchronization with the user’s behavior is required to cut out the number of unsatisfied users.
Indoor navigation system should be SCALABLE
Scalability allows the system to spread its range according to the requirement. Let’s understand this feature with the help of an example. Suppose a shopping mall, which already is enabled with indoor navigation system, is expanding its area for a larger complex. It would be much easier if the navigation system is adaptive and scalable in nature.
A scalable indoor navigation system helps in cost cutting and provides a wide range of options.
It should be equipped with Proximity Detection Technology
An indoor navigation system can only be efficient if features like proximity detection are integrated with the system. If a user’s phone gets detected by more than one device (like a beacon or WiFi system), the overall navigation can get all crumbled up. This happens due to conflict of instructions coming out from different devices to a single phone.
With the use of proximity detection technology, the cell phone of the users will be just be detected with the nearest beacon. It is seen that the accuracy of indoor navigation is directly proportional to the number of beacons functioning in the area.
These were the 4 most important features which, when combined, make indoor positioning system even more efficient.
