Ultra-wideband (UWB) is a wireless communication technology that uses low-energy, short-range radio waves to transmit large amounts of data over short distances. Unlike other wireless communication technologies that use narrowband signals, UWB signals use a very wide frequency range, typically spanning several gigahertz, which enables them to transmit data at extremely high speeds. UWB technology is used in a variety of applications, including high-speed data transfer, location tracking, and sensing. In the context of data transfer, UWB can be used to transfer large files, such as high-definition videos, between devices at speeds of up to several gigabits per second.

In location tracking, UWB can be used to accurately determine the location of objects or people within a confined space, such as a building or a room, with a high degree of precision. In sensing applications, UWB can detect objects’ presence, measure distance, and even detect motion. One of the advantages of UWB technology is its ability to operate in crowded radio frequency environments without interfering with other wireless communication technologies. This is because UWB signals are spread out over a wide frequency range and are designed to coexist with other wireless technologies.

During 2019, one of the largest theme parks in Hong Kong introduced the first UWB adoption into game environment in Hong Kong. Mega Fortune was responsible for digital communication among devices for tracking the children playing a 3D projection game scene with centimeters-level of accuracy. Mega Fortune also utilizes location-based service driven products equipped with the readiness and the reliability of indoor and outdoor positioning system. In 2019, an NGO worked with Mega Fortune for location-based service adaptations on their existing mobile application to enable extra technology to substantiate location-awareness assist visual impaired persons in a technology park in Hong Kong. Wireless fingerprinting and magnetic fields are captured for indoor positioning estimation to provide a coordinate on an app, speak-to-navigate approach is used for visual impaired app users.
