Case analysis: Cowin WiFi 6 joins hands with smart home enterprises to integrate high-density, large number of access and low-power optimization, providing good interoperability
Customer background：
Xiezhu Technology is a one-stop service provider for smart hotels and intelligent scenes in China. It provides the industry with leading intelligent hotel service solutions integrating software, hardware and Internet. It combines intelligent hardware and software to provide a full set of services for hotels and apartments to quickly transform into "future hotels" and future apartments. Based on "platform + terminal + application" to comprehensively upgrade the hotel, it adopts the industry's first zero-wiring, non-stop strong electricity customer control installation scheme, sets a variety of equipment control, scene customization, products in the body, to create a variety of intelligent scenes, so that customers can experience more comfortable, more convenient, more personalized service. Through comprehensive information integration and big data analysis, to achieve effective management of the hotel, so as to improve hotel revenue and customer satisfaction.
Business requirements:
Industrial WIFI6, frequency distribution in 2.4-2.5g / 4.9-6g / 5.925-7.125g
The challenge:
Intelligent scene the wide application of wireless terminals connected to the surge in the number of the wireless access bandwidth, number of concurrent, time delay, etc. Put forward higher requirements, the corresponding higher throughput and faster speed, support more concurrent connections, for many antenna can communicate with multiple terminals at the same time, the introduction of MU - MIMO technology is more capable to increase network speed, The need to connect more devices. 1800Mbps high-speed performance, support 160MHz bandwidth, 17 built-in antennas.
Problem Description:
The customer can provide a space size of 250* 250MM for placing antennas. At the same time, 17 antennas (5 2.4-2.5g, 8 4.9-6g and 4 5.925-7.125) should be placed in this space. Standing wave of all antennas is less than 2, gain is higher than 4DB and efficiency is higher than 60%. The isolation degree is higher than 20%, and the small space represents the interference between antennas before. Engineers play a crucial role in the debugging results of the isolation degree.
Solution:
1. The customer shall provide the original product model (including shell and finished circuit board), circuit diagrams of all circuit boards, mechanical assembly drawings and materials of plastic shell.
2. According to the above materials, the engineers conduct antenna simulation and design antenna according to the actual environment.
3. The location of the antenna and the space given by the structural engineer. For this purpose, the size of the aluminum alloy substrate of the antenna is defined as 240* 220MM in length and 17 antennas are evenly distributed.
The 17 antennas are fixed on the substrate with rivets and copper vibrator structure.
5. The final antenna sample is tested and accepted by the customer.
Economic benefits:
The customer successfully introduced the product to the market, and 10,000 units have been sold.
