lpwa standard

With the rise of smart cities and the acceleration of mobile connectivity, people are increasingly active indoors and the demand for information is growing, and location technologies are extending from outdoors to indoors. From motorcycle positioning to small product positioning in shopping centers, lpwa standardfrom vehicle navigation to indoor navigation in museums and airports, the demand for indoor positioning technology is growing.

There is a wide range of technologies and positioning solutions based on indoor positioning, which can be divided into wide area positioning and local area positioning based on the positioning coverage.

Wide-area interior positioning information technology can be achieved through a bearer on current wide-area networks, such as CDMA and GSM networks, with positioning system accuracy ranging from fifty to several hundred meters. The advantage is that it lies in the control signal to carry out a wide range of coverage nationwide, but the positioning accuracy is low, the communication power consumption is high, and the base station concurrent access terminal management capability is low.

Indoor positioning technologies include Bluetooth, Wifi, RFID, UWB and Lifi. Local indoor positioning technologies can reach the level of metre and sub-metre positioning accuracy, which is higher than the positioning accuracy of wide area positioning methods, but the signal coverage is small and the transmission distance is limited.

Lpwa lbs, ultra-low power indoor positioning extension outdoor

LPWA is a low-power wide-area communication technology born because of the rise of IoT, including NB-IoT, LoRa, Sigfox and other technologies. On the one hand, it makes up for the high power consumption and high cost of previous cellular communication technologies, and on the other hand, it makes up for the limitations of WiFi, Bluetooth, zigbee and other technologies in terms of transmission distance and access quantity. Therefore, combining low-power wide-area communication with indoor positioning networks such as Bluetooth and WiFi can maintain high positioning accuracy and expand the coverage of positioning signals, while extending indoor positioning to the outdoors.

Application of LPWA+LBS positioning technology solution

The application solutions of LPWA and location services can be widely used in smart scenic spots, loss prevention management for children and the elderly, asset tracking management, smart hospital location services, smart building visitor management and personnel location, factory personnel item location management, museum and exhibition smart navigation, etc.

Smart hospital location service management

At present, there are many problems in the hospital management, such as the medical equipment management process is not standardized, which leads to the loss of equipment handling, resulting in repeated procurement and asset waste; the real-time positioning of hospital nurses and security personnel cannot be controlled, and the personnel concerned are not protected in the first place when accidents occur.

LPWA+LBS positioning solution is used to locate medical equipment and medical assets, which makes it convenient for doctors to view the current location and detailed usage data of equipment in real time, improve the utilization rate of idle equipment, and realize the visual management of materials. Real-time positioning tracking of hospital nurses and security personnel can accurately obtain information of personnel in the corresponding area and mobilize relevant personnel for accident handling at the first time. Patients can wear positioning bracelets to view their location information and track and monitor their physical condition in real time. In addition, electronic medical guide provides hospital positioning navigation function, gives the patient corresponding department navigation route, improve the efficiency of medical treatment.

Suzhou search interest electronic titanium quasi-personal/items for positioning information system

Titanium quasi-person/goods positioning system developed by Suzhou Search Electronics accelerates the construction of smart cities and promotes the rapid landing of the Internet of Things through a positioning service solution that combines LPWA technology and indoor positioning network.

Titanium Quasi Positioning System is mainly applied to the positioning management of personnel and medical equipment in intelligent hospitals, the positioning management of personnel and goods in factories, the positioning monitoring of elderly people in nursing homes, the positioning management of corporate assets, the positioning management of prisons, and the management of visitors and personnel in intelligent buildings. The positioning accuracy can reach 3-5 meters, and the network deployment cost is lower compared with other positioning methods, making it the most cost-effective monitoring and control room positioning system in the industry.
