Wireless Indoor Positioning-
By utilising the (IoT) and pervasive connectivity, Wireless Indoor Positioning for establishing precise wireless indoor location information has become very crucial for satisfying increasing demands for location-based services. The indoor environment affects most Wi-Fi-based indoor location approaches that use wireless received signal strength (RSS)-based methodologies, which rely on signals from at least three reference access points.
The wireless indoor positioning system operates by utilising Wi-Fi access points that may transfer data to define coordinates. Using the multi alteration technique and the RSSI (received signal strength indicator) and MAC-address, the system may pinpoint the exact position of the user's device. Wi-Fi positioning accuracy is determined by the number of access points, building topology, and kind of device is in use. Modern Android devices may be able to provide indoor positioning as accurate as 2 to 3 metres.
UWB Outdoor Positioning-
UWB Outdoor Positioning systems can pinpoint locations within 20 cm or less in real-time. Signals with a wide range of frequencies can be monitored properly in terms of the time it takes for an encoded signal to journey from a transmitter to a receiver because of the capacity to precisely measure the "time of flight" of any radio wave is a function of bandwidth. The usage of a wide-frequency spectrum allows for a short transmission length. The signal is sent at a low power level with UWB, preventing interference with other radio systems such as cell phones and police radios.
Warehouse automation is one of the applications where the location accuracy of a UWB positioning system is clearly advantageous. Amazon has massive warehouses loaded with hundreds of thousands, if not millions, of different things; profitability rests on controlling labour expenses, which includes providing personnel with a mechanism to rapidly discover items when they are ordered by customers.
All of the different objects in a large warehouse may be simply mapped using UWB Outdoor Positioning systems. As items are scanned into stock by workers, scanners fitted with location tags communicate information about their location. The positions of things in three dimensions are recorded so that they can be quickly recovered to fulfil consumer orders.
IoT Based Physiological Monitoring Equipment
Internet of Things (IoT)-based physiological monitoring devices could be extremely valuable for patients during the present pandemic situation. This research provides an IoT-based system for real-time health monitoring that uses the patients' observed body temperature, pulse rate, and oxygen saturation, which are the most crucial metrics for critical care. The observed temperature, heart rate, and oxygen saturation level are displayed on a liquid crystal display (LCD), which can be readily synchronised with a mobile application for rapid access. The suggested IoT-based technique was tested and verified on five human test participants using an Arduino Uno-based device.
The system's results were promising: the data acquired from the system are saved relatively quickly. When compared to other commercially available devices, the system's results were confirmed to be accurate. During the COVID-19 epidemic, IoT-based gadgets could be extremely useful in saving people's lives. For more updates visit here - https://www.ubitrack.com/
