Company Profile
Shenzhen Nuclear Core IOT Technology Co., Ltd. (hereinafter referred to as "Nuclear Core IOT") was established in April 2020. It is a technological innovation enterprise for high-precision positioning, industrial operation monitoring and other IoT segments. The founding team of Nuclear Core IOT originated from AMD, TP-Link and other domestic and foreign industrial chain head enterprises, the company was founded at the beginning of the indoor positioning technology and application integration support and other aspects of the formation of considerable accumulation. Since its establishment, the Nuclear Core Internet of Things has successfully introduced a number of indoor high-precision positioning equipment based on AoA/AoD algorithm. It is the first manufacturer in China to independently develop mass-produced 2.4G Bluetooth AoA positioning base station and deploy 2.4G Bluetooth AoA plus fusion positioning scheme, leading the research on sub-meter positioning technology based on low-power Bluetooth scheme and the trend of localization of core equipment.
At present, the company is committed to the research and development of high-precision positioning equipment, algorithm engine design and application ecological cultivation with cross-industry, wide compatibility, easy integration and multi-technology integration, promoting the intelligent upgrading of government management and enterprise operation in related fields, and providing safe, reliable and efficient product technical support for upper-level partners.

Key Technologies and Key Products
key technology
AoA technology is based on a receiver and transmitter combination. A multi-antenna linear array device (base station) acts as a receiver, and another single-antenna device (beacon) acts as a transmitter, assuming that the radio wave acts as a plane wave surface instead of a sphere. If the transmitter sending a sine wave in the measurement space is located on the normal line perpendicular to the array line, each antenna in the array will receive the same phase of the input signal. If the transmitter is not normal, the receiving antenna will measure the phase difference between the channels and estimate the angle of arrival using the phase difference information.
AoAPositioning
AoApositioning
in AoD, the tracked device uses only a single antenna, while the transmitter device uses multiple antennas. The transmitting apparatus sequentially converts the transmitting antennas, so that the receiving side learns the antenna array architecture and converts the sequence. From an application point of view, a clear difference can be found between the two techniques. In AoD, the receiving device calculates its own position in space based on a plurality of target angles and positions; while in AoA, the receiving device tracks the arrival angle of each object in space.

key products
Core Internet of Things covers the whole technical chain of positioning base station equipment, positioning algorithm engine and positioning application program, and can realize the system application support of sub-meter (ideally up to centimeter level) high-precision positioning for complex indoor space, building ancillary space and large-scale semi-open space.
1. AoA/AoD positioning base station
Based on the low-power Bluetooth scheme and AoA/AoD positioning algorithm, the company has introduced a variety of sub-meter-level high-precision positioning equipment, which can achieve coverage support for the above-mentioned scenarios.
CL-GA10-P(2)
The equipment is divided into CL-GA10-P and CL-GA10-P 100.00g models, of which CL-GA10-P is a single network port model and supports PoE power supply. The CL-GA10-P2 is a dual-network port model, which can support DC and PoE cascade power supply. The maximum installation height of the base station is 10m, which can realize the radius coverage of 2 times the installation height, and accurately locate the target object in two dimensions.

CL-GA60-P2
The equipment is a long-distance positioning base station for large-scale closed or semi-open spaces such as terminal buildings, high-speed railway stations, stadiums and stadiums, as well as building ancillary spaces. It is recommended that the installation height of the equipment should not exceed 30m, which can achieve 2 times radius coverage and accurate positioning of the target object in two dimensions.

CL-GB20-P
The device is also known as AoA positioning from the base station, the use of RSSI positioning algorithm, is for only 0-dimensional (presence) detection of small space or one-dimensional positioning of the narrow corridor scene positioning design, compared to ordinary AoA positioning base station has a significantly lower cost. The maximum installation height is 10m, which can cover the radius of 2 times the installation height.

2. Localization algorithm engine
Core Internet of Things is named CoreLocation Engine(CLE), which is a supporting application software based on the combination of 2.4GHz low-power Bluetooth technology and AOA /AOD precise positioning algorithm. The positioning accuracy of the system can reach the order of 10cm. It obtains real-time positions for beacon terminals (personnel, vehicles and assets), and has its own visual interface to display position information in real time and open data interfaces for upper-layer applications, on this basis, historical track query, electronic fence alarm, video linkage detection and big data statistical analysis can be realized to meet the needs of different industry integrators and user positioning applications, and provide key technical support for information, precision and intelligent management based on location data in various scenarios.

3. Locating applications
positioning application program is mainly a standard application program (positioning assistant) for the positioning of the mobile phone, which can realize the high-precision positioning of the end user in the coverage scene. At the same time, the application provides an open interface to support raw data support for potential upper-level users in complex scenarios such as fence alarms, trajectory queries, and hotspot distribution.
