High accuracy location services is not a new industry, after years of development, precision, capacity, latency and other indicators of indoor positioning technologies have made a breakthrough. With increasing maturity of the industry, UWB, Bluetooth, RFID and other indoor positioning technology is also widely used in various fields, including the development of UWB indoor positioning technology momentum was particularly strong, high-precision indoor location field is rapidly becoming the most important part of .
The reason UWB indoor positioning technology to quickly develop the following points:
1) 10 cm accurate positioning of
UWB indoor location positioning technology is the industry's highest positioning accuracy location technology. Reasons localization algorithm, hardware and other equipment, UWB positioning system accuracy of different R & D will be slightly different. For example, UWB ehigh constant high precision positioning system uses wideband communication technology narrow pulse (high time resolution, the positioning error is reduced), multi-source data fusion (positioning system effectively enhance immunity) and the time series signal processing techniques (strong complex multipath environments, path of the first signal is extracted), 10cm high-precision positioning can be achieved.
2) Comprehensive location services
UWB positioning system not only provides positioning, but also on the basis of positioning on a comprehensive expansion of location services, such as historical track playback, staff attendance, electronic fence, behavioral analysis, intelligent data logging, etc. . These services based on location data, can assist managers in the enterprise security management, can effectively reduce the occurrence of accidents.
3) Low-power devices, working time is long
pulse UWB Positioning technique using a batch of data is transmitted, the pulse duration is very short, typically 0.20ns between 1.5ns, there are empty duty cycle, the system power can be done is very low, only a few hundred μW power consumption in high-speed communication system when tens of mW. Civil UWB device power is generally required power is about 1/100 of the conventional mobile phone, the required power is about 1/20 of Bluetooth devices. Thus, the battery life of UWB devices, with respect to the conventional wireless device has great advantages.
4) small interference to other devices
Since UWB pulses very narrow, a very wide band, which corresponds to the bandwidth of 1000 or 30,000 channels FM radio channel, so the power density per unit bandwidth is very low. US FCC for UWB transmit power to do a strictly limited, the power density is even lower than the average noise level (for example, less than the radiation a laptop). Therefore, the impact of UWB positioning technology to other equipment is minimal.
The label 5) 1S can work simultaneously, high-capacity
bandwidth of UWB used in the above 1GHz, even up to several GHz, then each transmits a UWB signal of very short duration. Plainly, we considered the communication signal can be different widths with vehicle, bicycle (UWB signal), automobiles (narrowband signal), the width of the road constant (time resources), the narrower the vehicle, to accommodate the more vehicles on the road, such as only bike ride and only when the cars on the road, bicycle capacity will be much more than cars on the road. Thus, UWB system capacity, can accommodate hundreds of tags simultaneously positioned.
As EHIGH UWB locating an expert constant high, is a leading global 10cm high accuracy location service provider, has 8 years of professional experience in the field of indoor positioning field, six years of product development experience, with a complete product line. We have always been committed to provide users with set of software, hardware, and precise positioning solutions for the integration of localization services.
Currently EHIGH Constant high-UWB positioning has been successfully applied to the tunnel, chemicals, prisons, wisdom factories, tunnels, coal mines, hospitals, nursing homes, construction sites and more than 10 industries, the implementation of the project landing 500+, market share lead.
For better, faster to help companies achieve precision personnel location, EHIGH constant high opened a number of offices across the country, Southwest (Chengdu) headquarters, East China (Shanghai) office, Central China (Changsha) office, North ( Beijing) office in South China (Shenzhen) office, and strive to bring better service for business users.
