UWB vs BLE vs GPS: Which One for Indoor Positioning?

You already know the concepts. Now you have to pick one. That is the hard part. On paper, UWB, BLE, and GPS all promise to tell you where something is. In practice they answer very different questions, at very different price points, with very different accuracy. Choose wrong and your prototype either bleeds budget or […]

UWB Indoor Positioning: A Beginner’s Guide

Indoors, GPS quits. Walk into a warehouse and your phone’s blue dot drifts through walls, lands two aisles over, then gives up. The signal from satellites cannot punch through a steel roof and metal racking, so anything that needs to know where it sits, down to the centimeter, hits a wall the moment it steps […]

UWB Arduino Positioning: How to Get Real X,Y Coordinates

Most “uwb arduino” tutorials stop at distance. You wire up two off-the-shelf UWB modules, run an open-source ranging library, and the serial monitor prints a number in meters. Then you try to turn three of those distances into an actual point on the floor, and the whole thing falls apart. That gap is the reason […]

Creator Kit vs Creator Expansion Kit: Which Q1 UWB Kit Is Right for Your Project?

Hello! This is Freegrow. GrowSpace’s UWB kit line comes in two configurations built around the same 10–30 cm accuracy, but sized for different stages of a project: the Creator Kit and the Creator Expansion Kit. Both kits use the same UWB anchor-based positioning technology. The difference is in what’s in the box, how the system […]

UWB Smart Key, Getting Truly “Smart” with UWB Technology

Hello, this is Freegrow. Today, you do not need to take the car key out of your pocket. You touch the door handle, and the car opens.You press a button, and the engine starts. This convenient feature comes from the smart key. Recently, a more advanced smart key using UWB (Ultra Wideband) technology has appeared […]

Mobile Anchor Distance Measurement Test by OS

Hello, this is Freegrow. Today, we introduce a simple test using our Mobile Anchor. We wanted to see how far the distance can be measured on Android and iOS. One of the most common questions from users is: “How far can my smartphone stay connected to the Mobile Anchor?” So we ran the same test […]

Smart Exhibition Technology: BLE and UWB for Location Curation

Hello, this is Freegrow!These days, museums, art galleries, and exhibitions focus on smart exhibition technology. It is not only about how you design the exhibition, but also about what kind of visitor experience you provide. A key part of this is location-based curation technology. This system detects where the visitor is and gives the right […]

UWB Indoor Positioning : How to Install Anchors for Better Z-Axis Accuracy

Anchor installation is the step most teams underestimate when their UWB results come out wrong. Hello, this is Freegrow 😊When you set up a UWB-based indoor positioning system, most people only think about the XY plane. But what if you need height (Z-axis) information? For example, worker safety, drone position, or separating multi-level spaces. With […]
