What is integrated positioning technology?
The integrated positioning technology integrates all positioning methods on the market, including GPS, base station positioning, Wi-Fi positioning, Bluetooth positioning, and sensor positioning, which can be described as integrated positioning technology sets.
In our daily lives, more than 80% of the information belongs to related information with spatial location features. Location information and people’s production and daily life, both in indoor or outdoor environments, quickly and accurately obtain location information of a mobile terminal, and the need to provide location-based services is becoming increasingly urgent.
Demand for positioning has been more than just a rough track, and navigation, in the era of the Internet, high-precision positioning is becoming just a need.
In the current practice, increasing the positioning function requires a separate positioning technology, which will also mean additional costs. Therefore, it is destined for the users to consider the positioning scheme to generate tangible value, such as security monitoring, vehicle monitoring, prison guard, unmanned aerial vehicles, agricultural machinery, construction machinery, surveying and mapping equipment, machines, and objects networked terminals.
With the emergence of new applications (such as autonomous vehicles and unmanned aerial vehicles), the development of technological breakthroughs (such as dual-band chipsets for the mass market), and market services optimization (in some countries, high-precision positioning service cheap or even free), high-accuracy location-based services market is developing very rapidly, and its application will be more than just a professional level of service, it will become a popular level of service.
Therefore, precise time and space services are gradually replacing the current location services and becoming the core direction of industrial development, and the popularity of high-precision applications of innovative development of the industry has become an inevitable trend.
Bluetooth radio technology to release high-precision positioning of charm
The high-precision positioning is becoming just a need, this demand can be achieved is also dependent on precipitation technology for a long time, along with advances in communications technology and the popularity of Bluetooth, WiFi, UWB, 5G, and so on, each communication positioning solutions provider in precision aspects in constant progress, improve technology provides the basis for the application of high-precision positioning.
Bluetooth communication capabilities for its initial public known, the four major applications of Bluetooth are audio transmission, data transmission, location services, and Mesh networks. Now, location-based services will be the fastest-growing application of Bluetooth applications.
According to SIG recently released “2021 Bluetooth market the latest information,” while the new crown outbreak travel and work restrictions and the consequent results in the amount of short-term deployment of Bluetooth location-based services have declined about 25 percent.
However, as the market for indoor location and asset tracking use cases continued to have interest, analysts expect Bluetooth location service deployments will bounce back by the end of 2021, and between now and 2025 to achieve a 32 percent compound annual growth rate.
By the end of 2021, the total position of Bluetooth service deployment will reach 262,000.
Only from the point of view in 2021, more than other indoor navigation location services deployments: While location-based services solutions support from near class service to many different use cases such as asset tracking, indoor navigation services are deployed at each location necessary.
At present, nearly 80% of Bluetooth deployment of location-based services includes indoor navigation.
Retail Bluetooth use cases to lead the deployment of location-based services: a decent amount of Bluetooth technology in a number of different vertical areas emerged as a strong growth trend. At present, 66% of the amount of the deployment of Bluetooth support retail use cases, is expected to deploy Bluetooth amount will double in the next five years.
Bluetooth technology has now become a huge ecological, 2025, Bluetooth device shipments will reach 6.4 billion. Emerging Bluetooth AoA / AoD technology will lead to higher more excellent positioning performance, and Bluetooth-based massive ecological, this new technology will help accelerate the adoption and landing.
Only from the location services application point of view, in 2025, Bluetooth with real-time asset tracking deployments will reach 516,000 cases; deployments of indoor location services will grow by 2 times; Bluetooth medical location service solutions will grow by about 5 times, to about 380,000.
In addition, a smartphone is a digital key, and now has been very acceptable to the phone as a digital wallet payment, and smartphones will continue to expand their role in daily life.
Dispute positioning technologies: integrated positioning technology is the way
Fragmentation is the biggest feature of the networking industry, networking applications have different requirements that vary widely, like all networking applications no one communications technology adaptation, like, no one can meet all targeting positioning technology scene and in many applications scene, after the functional needs, in order to pursue better value for money needs to be more integrated positioning technology of location applications, integrated positioning technology has gradually become a trend in the industry.
At present, with the integrated positioning technology, many manufacturers have considered or are trying in the system development process.
Bluetooth AOA + UWB integrated positioning technology
The former advantage is that small area of the scene, and the latter even greater advantage of large areas of the scene, their cost advantages and disadvantages of the two scenarios have huge differences.
To address the limitations of a single system of two or more, plus a targeting site diverse scenes even complex, the fusion of two isomers positioning schemes, to improve the reliability and confidence in the results of the Bluetooth AOA + UWB integrated positioning technology, the integrated positioning system to solve a single anti-blocking ability UWB difference, positioning data transitions becomes large;
And solve big problems assuming that the error caused by a single terminal height AoA positioning system, while fully meeting the positioning needs effectively reduces the cost of deployment.
It is reported that there are already a number of projects using the Bluetooth AOA + UWB integrated positioning technology such as the floor, covering prisons, nursing homes, hospitals, substations, oil and gas pipelines, and other industries. In the future will also carry out more in-depth research work and achievements in the field of indoor positioning.
5G + Bluetooth AOA integrated positioning technology
5G allows service providers to see the value of indoor positioning technology and a combination of 5G since operators have a natural ability to indoor communication network construction and operation and maintenance.
5G operators to deploy in accordance with the order after the first indoor-outdoor, which is the first deployment of an outdoor macro base station, after the deployment of small indoor base stations. With 5G indoor network coverage construction, operators began to consider the deployment of a precise position 5G Communications + network, which will locate a base station and base station deployment of converged communications.
