  There are many systems for indoor navigation specially built for visually
impaired people but only some has good accuracy for navigation. While there are
solutions like global navigation satellite systems for the localization
outdoors, problems arise in urban scenarios and indoors due to insufficient or
failed signal reception. To build a support system for navigation for visually
impaired people, in this paper we present a comparison of indoor localization
and navigation system, which performs continuous and real-time processing using
commercially available systems (Beacons and Decawave) under the same
experimental condition for the performance analysis. Error is calculated and
analyzed using Euclidean distance and standard deviation for both the cases. We
used Navigine Platform for this navigation system which allows both
Tri-lateration as well as Fingerprinting algorithms. For calculating location
we have used the concept of Time of Arrival and time of difference of arrivals.
Taking into concern about the blind people, location is important as well as
accuracy is necessity because small measurement in the walk is important to
them. With this concern, in this paper, we are showing the comparative study of
beacons and Decawave. The study and the accuracy tests of those systems for the
blind people/user's in navigating indoor are presented in this paper.
