Case study: Cowin antenna's 4G flexible antenna eliminates hidden dangers in the security field and cooperates in disaster prevention.
Customer background:
Hangzhou Tpson, as a provider of new fire protection and new power solutions, is a national high-tech enterprise focusing on the research of current fingerprint AI (Elec AI) algorithm and fire early warning technology. Tpson has end-to-end product research and development capabilities. Cloud platforms, early warning terminals and alarm terminals are widely used in safe cities, smart communities, universities and other industries with intelligent fire protection scenarios, and use power AI SAAS services to connect a better world.
Antenna performance requirement:
Since 80% of wireless data traffic occurs indoors, an important factor for building owners to consider is wireless connectivity, ensuring that it can support the growing number of IoT applications, including smart building applications, Connect security, and monitoring, early warning systems. For large buildings, rely on LTE network to solve.
The challenge:
For fire, timely and effective real-time monitoring plays a vital role. A stable communication system ensures timely transmission of information.
Problem Description:
For indoor and some public areas, the instability of the signal has higher requirements on the performance of the antenna, which requires the antenna to have high TRP (Total Radiated Power Sensitivity) and TIS (Total Isotropic Sensitivity), so that for weak operator signals can be obtained in time.
Solution:
1. The customer provides the original product model (including the shell and the finished circuit board), the circuit diagram of all the circuit boards, the mechanical assembly drawing and the material of the plastic shell.
2. Based on the above materials, the engineers will conduct antenna simulation and design the antenna according to the actual environment.
3. Determine the position of the antenna and the space given by the structural engineer. For this reason, we define the size of the antenna as length 68.8*width 30.4MM, the internal structure of the shell is irregular, and the flexible board is irregular.
4. The use of the engraving machine allows engineers to greatly shorten the development time, and the delivery of antenna samples is successfully completed within a week. The product has passed the active test in the darkroom, and the TRP can reach 20, and the TIS can reach 115, which has been verified by the customer's actual machine.
Economic benefits:
The customer has successfully launched the product to the market and has achieved sales of 100,000 units.
